An overview of Vaping Associated Lung Injury (VALI) Hosts: Audrey Bree Tse, MD Larissa Laskowski, DO Brian Gilberti, MD https://media.blubrry.com/coreem/content.blubrry.com/coreem/Vaping_Associated_Lung_Injury.mp3 Download Leave a Comment Tags: Pulmonary, Toxicology Show Notes Why this matters As of Oct 15, vaping has been associated with acute lung injury in over 1400 people 33 deaths have been confirmed in 24 states 70+% of those with VALI are young men A large number of patients are requiring ICU/ intubation/ ECMO 4 main ingredients in solvent +/- Flavor additives +/- Nicotine or THC (Tetrahydrocannabinol) Propylene Glycol (PG) Vegetable Glycerin (VG) CDC definition of VALI (Vaping Associated Lung Injury) Using an e-cigarette (“vaping”) or dabbing* in 90 days prior to symptom onset AND Pulmonary infiltrate, such as opacities, on plain film chest radiograph or ground-glass opacities on chest CT AND Absence of pulmonary infection on initial work-up.  No evidence in the medical record of alternative plausible diagnoses (e.g., cardiac, rheumatologic, or neoplastic process). *Dabbing allows the user to ingest a high concentration of THC.  Butane Hash Oil (BHO), an oil or wax-like substance extracted from the marijuana plant, is placed on a “nail” attached to a specialized glass bong called a “rig.” A blow torch is used to heat the wax, which produces a vapor that can then be inhaled to supposedly produce an instantaneous effect. Pathophysiology At present, no single compound or ingredient has emerged as the cause, and there may be more than one cause The only common thread among the cases is that ALL patients reported using e-cig or vaping products Leading potential toxins: Vaping products containing THC concentrates: most cases are linked to THC concentrates that were either purchased on the street or from other informal sources (meaning not from a dispensary) Vitamin E acetate: nutritional supplement safe when ingested or applied to the skin (but likely not when inhaled) has been found in nearly all product samples of NY state cases of suspected VALI vitamin E acetate is NOT an approved additive at least by NYS Medical Marijuana program Other potential toxins: IT CANNOT BE UNDERSTATED that a small percentage of persons w/ VALI have reported exclusive use of nicotine-containing vape products, such as JUUL; as such, we must consider the potential toxicity of standard e-liquid or vape juice Flavor additives, that exists as chemical aldehydes: irritating and potentially damaging to lung tissue

An overview of septic arthritis. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Septic_Arthritis.mp3 Download Leave a Comment Tags: Infectious Diseases, Orthopedics Show Notes Episode Produced by Audrey Bree Tse, MD Background Bacteria enters the joint by hematogenous spread due to absence of basement membrane in synovial space from invasive procedures, contiguous infection (e.g. osteomyelitis, cellulitis), or direct inoculation (e.g. plant thorns, nails) WBCs migrate into joint → acute inflammatory process → synovial hyperplasia, prevents new cartilage from forming, pressure necrosis on surrounding joint, purulent effusion Why do we care?  irreversible loss of function in up to 10% & mortality rate as high as 11% Cartilage destruction can occur in a matter of hours Complications include bacteremia, sepsis, and endocarditis Etiology Risk factors: extremes of age, RA, DJD, IVDA, endocarditis, GC, immunosuppression, trauma, or prosthesis Organisms:  Staph: staph aureus (most common), MRSA, Staph epidermis N gonorrhea: young healthy sexually active adults Strep: group A & B GNRs: IVDA, diabetics, elderly Salmonella: sickle cell disease Cutibacterium acnes: prosthetic shoulder infection Consider mycobacterial & fungal in more indolent courses Presentation Typically a single, warm, erythematous, tender joint (#1: knee (50% of cases) → hip, shoulder, ankle) *Any joint can be involved! IVDA can involve sacroiliac, costochondral, & sternoclavicular joints  Classic teaching: very painful with ROM, but this is not always present! Joint usually held in position of maximum joint volume Prosthetic joints may have less pain than expected for a septic joint given changed anatomy and disrupted nerve endings In 10-20% of cases, can see polyarticular involvement GC typically monoarticular but commonly polyarticular Often have fever & separate infection as well (only see fever in ~60% of cases) Diagnostics Arthrocentesis:  Gold standard  Tap joint even if acceptable ROM: septic joints can have normal motion so it does not exclude the diagnosis! Use ultrasound if possible Relative contraindications: overlying cellulitis (risk of seeding joint) or severe coagulopathies (weigh risk of creation or worsening of iatrogenic hemarthrosis) Keep in mind that a “dry tap” may occur due to incorrect needle placement, absent/ minimal joint effusion, ort mechanical obstruction Note: talk to ortho colleagues if prosthesis present prior to per...

A look at the most common type of seizures in the young pediatric population. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Febrile_Seizures.mp3 Download Leave a Comment Tags: Pediatrics Show Notes Background * The most common type of seizure in children under 5 years of age * Occur in 2-5% of children * In children with a fever, aged 6 months to 5 years of age, and without a CNS infection * Risk Factors * 4 times more likely to have a febrile seizure if parent had one * Also increase in risk if siblings or nieces / nephews had one * Common associated infections * Human Herpesvirus 6 * Human Herpesvirus 7 * Influenza A & B * Simple Febrile Seizure * Generalized tonic-clonic activity lasting less than 15 minutes in a child 6 months to 5 years of age * Complex Febrile Seizure * Lasts longer than 15 minutes, occurs in a child outside of this age range, are focal, or that recur within a 24-hour period. Diagnostics / Workup * Gather thorough history and perform thorough physical exam * Most cases will not require labs, imaging or EEG * If e/o meningitis, perform LP * AAP suggests considering LP in: * Children 6-12 months who are not immunized for H flu type B or strep pneumo * Children who had been on antibiotics * For complex seizures, clinician may have a lower threshold for obtaining labs * Hyponatremia is more common in this group than in the general population. * LPs are more commonly done by providers, but these are low yield with one study showing bacterial meningitis being diagnosed in just 0.9% (Kimia 2010), all of whom did not have a normal exam or negative cultures. * Neuroimaging is also exceedingly low yield if the patient returns to baseline (Teng 2006) * One study that showed that the duration of complex febrile seizure, being greater than 30 minutes, was associated with a higher incidence of bacterial meningitis. (Chin 2005) * Of they have history and exam concerning for meningitis, they should get an LP * If they look dehydrated or edematous, you would have more of a reason to get a chemistry Treatment * Benzodiazepine if seizure lasted for >5 minutes, either IV or IN * Supportive care * Tylenol or motrin if febrile * Fluids if signs of dehydration * Antipyretics “around the clock” * A majority of data show no benefit in preventing recurrence of seizure * One study (Murata 2018) found that giving tylenol q6h at 10 mg/kg for the first 24 hours following the initial seizure decreased the rate of recurrence when compared to children who did not receive ant...

A look at this common and controversial topic. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Acute_Otitis_Media.mp3 Download Leave a Comment Tags: Pediatrics Show Notes Background: * The most common infection seen in pediatrics and the most common reason these kids receive antibiotics * The release of the PCV (pneumococcal conjugate vaccine), or Prevnar vaccine, has made a big difference since its release in 2000 (Marom 2014) * This, along with more stringent criteria for what we are calling AOM, has led to a significant decrease in the number of cases seen since then * 29% reduction in AOM caused by all pneumococcal serotypes among children who received PCV7 before 24 months of age * The peak incidence is between 6 and 18 months of age * Risk factors: winter season, genetic predisposition, day care, low socioeconomic status, males, reduced duration of or no breast feeding, and exposure to tobacco smoke. * The predominant organisms: Streptococcus pneumoniae, non-typable Haemophilus influenzae (NTHi), and Moraxella catarrhalis. * Prevalence rates of infections due to Streptococcus pneumoniae are declining due to widespread use of the Prevnar vaccine while the proportion of Moraxella and NTHi infection increases with NTHi now the most common causative bacterium * Strep pneumo is associated with more severe illness, like worse fevers, otalgia and also increased incidence of complications like mastoiditis. Diagnosis * The diagnosis of acute otitis media is a clinical one without a gold standard in the ED (tympanocentesis) * Ear pain (+LR 3.0-7.3), or in the preverbal child, ear-tugging or rubbing is going to be the most common symptom but far from universally present in children. Parents may also report fevers, excessive crying, decreased activity, and difficulty sleeping. * Challenging especially in the younger patient, whose symptoms may be non-specific and exam is difficult * Important to keep in mind that otitis media with effusion, which does not require antibiotics, can masquerade as AOM AAP: Diagnosis of Acute Otitis Media (2013)* * In 2013, the AAP came out with a paper to help guide the diagnosis of AOM * Moderate-Severe bulging of the tympanic membrane or new-onset otorrhea not due to acute otitis externa (grade B) * The presence of bulging is a specific sign and will help us distinguish between AOM and OME, the latter has opacification of the tympanic membrane or air-fluid level without bulging (Shaikh 2012, with algorithm) * Bulging of the TM is the most important feature and one systematic review found that its presence had an adjusted LR of 51 (Rothman 2003) * Classic triad is bulging along with impaired mobility and redness or cloudiness of TM

A look at foot fractures – which can be splinted and which may need to go to the OR. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Foot_Fractures.mp3 Download Leave a Comment Tags: Orthopedics Show Notes Background: * Why do we care about Jones fractures? * Propensity for poor healing due to watershed area of blood supply * Fifth metatarsal fractures account for 68% of metatarsal fractures in adults * Proximal 5th metatarsal fractures are divided into 3 zones (93% zone 1, 4% zone 2, 3% zone 3) * Zone 1 (pseudo-Jones): * Tuberosity avulsion fracture * Typically avulsion type injuries due to acute episode of forefoot supination with plantar flexion * Typical fracture pattern is transverse to slightly oblique * Zone 2 (Jones fracture): * Fracture at the metaphyseal-diaphyseal junction of the fifth metatarsal * Typically acute episode of large adduction force applied to forefoot with the ankle plantar flexed * Zone 3: * Proximal diaphyseal stress fracture * Typically results from a fatigue or stress mechanism Clinical Presentation: * History of acute or repetitive trauma to forefoot * Fracture type / pattern closely related to injury location * Foot often swollen, ecchymotic, very tender to fifth metatarsal +/- crepitus, inability to hear weight Diagnosis: * Clinical exam: * Evaluate skin integrity * Check neurovascular status * Evaluate toes/ feet/ ankles/ tib fib/ knees/ hips, involved tendon function, associated adjacent structures (Achilles, ankle ROM/ function, etc) * 3 XR views: lateral, anteroposterior, 45* oblique *  Acute stress fractures are typically not detected on the standard 3 views; therefore, repeat XRs 10-14d after onset of sx (may see radiolucent reabsorption gap around fracture) * For more complex mid foot trauma, consider CT to r/o Lisfranc Treatment: * Consider classification of fracture, patient demographics & activity level when deciding on treatment * Tertiary care centers that have access to Orthopedics/Podiatry services * Consider consultation for “true” Jones fractures, as some cases may be operatively managed acutely and/or for expedited follow-up to be arranged * If working in community/rural locations: other than patients that present with “open” injuries, concerns for compartment syndrome (almost never), and “high-end”/professional athletes, there are generally no other circumstances that would require expedited transfer to a tertiary care center for immediate further evaluation. * Less favorable outcomes associated with certain patient factors: female gender, DM, obesity

A discussion with Dr. McNamara and Dr. Leifer on the essentials and beyond of debriefing https://media.blubrry.com/coreem/content.blubrry.com/coreem/Debriefing.mp3 Download Leave a Comment Tags: Resuscitation, Simulation Show Notes TAKE HOME POINTS * Debriefing after a clinical case in the ED is a way to have an interprofessional, reflective conversation with a focus on improving for the next patient.  We can debrief routine cases, challenging cases, or even cases that go well. * Follow a structure when leading a debrief. * The prebrief sets ground rules and informs the team that the debrief is optional and will only take 3-5 minutes. * Introduce names and roles * Then give a one-liner about what happened in the case, followed by a plus/ delta: address  what went well and why, then how to improve * Finally, wrap up with take home points * Pitfalls to watch out for in clinical debriefing include: * Avoid siloing or alienating any learners.  Learn from all your colleagues on your team- it’s less about medicine and more about interprofessional and systems issues * Don’t pick on individual performance.  It’s not about shaming- it’s about improving patient care * Avoid “guess what I’m thinking” questions; ask real questions * Proceed with caution in order to dampen or avoid psychological trauma and second victim syndrome.  The learner may ask “was this my fault?”; we never want a learner to feel this way.  Ask, what systems supported or did not support you today?  Talk about what happened.  Avoid shame and blame. * Have the right values and do it for the right reasons. ADDITIONAL TOOLS PEARLS Debriefing Tool INFO Model: GUESTS Dr. Shannon McNamara completed residency in Emergency Medicine at Temple University hospital and fellowship in Medical Simulation at Mount Sinai St. Lukes-Roosevelt.

Age-adjusted D-dimers are ready for use and it doesn’t matter if your assay uses FEU (cutoff 500) or DDU (cutoff 250). For FEU use an upper limit of 10 X age and for DDU use an upper limit of 5 X age. For now, subsegmental PEs should continue to routinely be anticoagulated even in the absence of a DVT. Keep an eye out for more research on this area. Although outpatient management of select PE patients (using sPESI or Hestia criteria) may be standard practice, the evidence wasn’t strong enough for ACEP to give it’s support Patients with DVT can be started on a NOAC and discharged from the ED sPESI Tool (MDCalc.com) PERC Decision Tool (MDCalc.com) Read More REBEL EM: ACEP Clinical Policy on Acute VTE 2018 Core EM: PE Rule-Out Criteria RCT Core EM: Age-Adjusted D-dimer (Using D-dimer Units) Core EM: Age Adjusted D-dimer in PE - The ADJUST-PE Trial REBEL EM: Is It PROER to PERC It Up References ACEP Clinical Policies Subcommittee.

Consider early airway management and get your consultants involved early for operative management Endocarditis is a tricky diagnosis and will often be subtle. Any patient with a prosthetic valve and a fever has endocarditis until proven otherwise. Suspect it in any patient with fever and a murmur, get lots of cultures and remember that TEE is the gold standard but, TTE is highly specific Finally, penetrating neck trauma.

This week we discuss the disutility of orthostatic vital signs as a diagnostic tool in patients with suspected volume loss. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Podcast_140_0_Final_Cut.m4a Download Leave a Comment Tags: Cardiology, Orthostatic Hypotension Show Notes Summary: Based on the limited available evidence, it’s unlikely orthostatic vital sign measurement can be used to determine which patients have volume loss and which do not. The baseline prevalence of orthostatic vital signs is common and patients will not always develop orthostatic vital signs in response to volume loss. Therefore, there will both be patients who are orthostatic by numbers without volume loss and there will be patients with volume loss who are not orthostatic by numbers. Symptoms, with the exception of inability to stand to have orthostatics performed, are not useful either. Bottom Line: Based on the low overall sensitivity of orthostatic vital sign measurements, they should not be used to influence clinical decision making.

More pearls from our fantastic morning report series. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Podcast_Episode_134_0_Final_Cut.m4a Download 2 Comments Tags: ALL, Altered Mental Status, Hyperleukocytosis, Hyponatremia, Leukostasis Show Notes Take Home Points 1. When seeing patients with AMS, think of the 5 broad categories of pathologies - VS abnormalities, toxic-metabolic, infectious causes, CNS abnormalities and, lastly as a diagnosis of exclusion - psychiatric issues 2. In kids with AMS, think of zebra diagnoses and toxic ingestions and remember that primary psychosis is rare 3. Patients with ALL are susceptible to developing hyperleukocytosis. If the WBC is > 100K, think about getting hematology on the line to initiate chemo induction and leukopheresis 4. Always think about electrolyte disorders, particularly hypoNa in patients with global AMS. Remember to treat severe hypoNa w/ hypertonic saline and, to correct slowly as to avoid ODS Read More LITFL: HSV Encephalitis EM Cases: Episode 60 - Emergency Management of Hyponatremia Core EM: Severe Hyponatremia Core EM: Episode 58: Hyponatremia Read More

This week we dive into the rare but potentially fatal, and difficult to diagnose, air embolism. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Episode_132_0_Final_Cut.m4a Download 2 Comments Tags: Air Embolism, Central Lines, Hyperbaric Oxygen Show Notes Take Home Points Air embolism is a rare but potentially fatal complication of central line placement and some surgical procedures and of course of as the result of barotrauma. Recognizing the signs and symptoms of air embolism can be tricky because it will look like any other ischemic process.  Consider air embolism if you have a patient that rapidly decompensates after placement of a central line, the most likely culprit for those of us in the ED. Treatment should focus on supportive cares.  Give supplemental O2, IV fluids and hemodynamic support and consider hyperbarics and cardiopulmonary bypass for the super sick patient.

Consider an ocular ultrasound! It’s quick, shockingly easy to do, and can help point you toward a diagnosis you may have otherwise overlooked.  I have made it my practice now to include a quick look in the physical exam of my patients with a concerning sounding headache or a headache with neurologic symptoms.  Consider IIH particularly in an overweight female of child bearing age with a subacute headache, but remember patients outside that demographic can have IIH as well. Consider CVST in a patient with a thrombophilic process like cancer, pregnancy or the use of OCPs or androgens or in a patient with a recent facial infection like sinusitis or cellulitis.

This week we dive into a recent journal article questioning whether we should tap all ascites. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Episode_123_0_Final_Cut.m4a Download Leave a Comment Tags: Albumin, Cirrhosis, Paracentesis, SBP, Spontaneous Bacterial Peritonitis Show Notes Take Home Points SBP is a difficult diagnosis to make clinically. While patients may have the triad of fever, abdominal pain and increasing ascites, they are far more likely to only have 1 or 2 of these symptoms In patients admitted to the hospital with ascites, consider performing a diagnostic paracentesis on all patients as limited literature shows an association with decreased mortality and, the procedure is simple and low risk Once you get the fluid, focus on the cell count: WBC > 500 or PMN > 250 should prompt treatment with a 3rd generation cephalosporin and albumin infusion Gaetano et al.

Be suspicious of a dislocation in any patient who describes the joint moving out of place or if they have significant swelling, joint effusion or ecchymosis despite normal X-rays In all patients with suspected dislocation, perform a neurovascular exam immediately as popliteal artery injury is common. If they’ve got an absent DP or PT pulse, reduce immediately and get a CT angiogram as quickly as possible to assess for popliteal injuries If distal pulses are intact, you can either do ABIs and if normal, observe and repeat them or get a CTA.

The brown recluse spider is found in the Midwest and presents as local pain and swelling but carries the risk of a necrotic ulcer The black widow spider is found all around the US and presents with either localized or generalized muscle cramping, localized sweating and potentially tachycardia and hypertension.  Treatment is symptom management with analgesics and benzos. The bark scorpion usually presents with localized pain and swelling, but particularly in children, may present with a serious systemic presentation including jerking muscle movements, cranial nerve dysfunction, hypersalivation, ataxia and opsoclonus, which is the rapid, involuntary movement of the eyes in all directions. Treatment is supportive cares, but remember to call your poison center to ask about antivenin.

If your workup is reassuring, isolated tachycardia in and of itself shouldn’t change your disposition. Supplemental O2 is not necessary in the management of AMI patients with an O2 sat > 90% and, may be harmful Until further study and prospective validation has been performed, we’re not going to recommend embracing the Canadian decision instrument on predicting dysrhythmias after a syncopal event.

Should we intubate patients in cardiac arrest? We discuss this topic and some basics of running a good arrest. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Episode_108_0_Final_Cut.m4a Download Leave a Comment Tags: Advanced Airway Management, Cardiac Arrest, Critical Care, Resuscitation Show Notes Take Home Points Intra-arrest intubation does not appear to improve outcomes. For most patients, support with BVM, or possibly an LMA, is adequate. Instead of securing an advanced airway, focus on the two things that clearly make a difference in outcomes - good compressions and defibirillation Good compressions should be fast and hard and you must minimize interruptions in compressions to minimize interruptions in perfusion Don’t forget that a great resuscitation requires great preparation.

Prompted by the recent CAMEO trial publication on icatibant, we dive into angioedema with a focus on airway management. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Episode_107_0_Final_Cut.m4a Download Leave a Comment Tags: ACE Inhibitors, Allergy/Immunology, Angioedema, Icatibant Show Notes Take Home Points Airway management is paramount, expect a challenging intubation and consider controlling the airway early When controlling the airway, consider an awake approach and fiberoptics if available. Always be prepared for the can’t intubate, can’t oxygenate scenario with a double set up. If the patient has urticaria and pruritus, the process is likely histamine mediated and will respond to typical anaphylaxis treatment Finally, observe the patient for progression of swelling and don’t forget to stop the inciting medication Read More Core EM: Angioedema EMCrit: Podcast 145 – Awake Intubation Lecture from SMACC ERCast: Angioedema REBEL EM: Icatibant Doesn’t Improve Outcomes in ACE-I Induced Angioedema The SGEM: Icatibant Bites the Dust - For ACE-I Induced Angioedema Read More

This week we drop into some of the nitty gritty on PSA including preparation and patient assessment as well as discuss some common pitfalls. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Episode_106_0_Final_Cut.m4a Download Leave a Comment Tags: Pitfalls, Procedural Sedation, PSA Show Notes Take Home Points Always perform a full pre-PSA evaluation including an airway assessment. Time of last meal shouldn’t delay your sedation based on the best available evidence. Always do a complete setup including consideration of different agents, dosage calculations, preparation of airway equipment and reversal agents. PSA serious adverse events are rare but you still must be prepared for them. Careful agent selection and dosing can help prevent issues but, know your outs. If apnea develops, do some basic maneuvers before you reach for the BVM or laryngoscope.

This week we dive into some of the initial considerations in the resuscitation of major burn patients. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Episode_101_0_Final_Cut.m4a Download Leave a Comment Tags: Carbon Monoxide, Cyanide, Major Burns, Trauma Show Notes Take Home Points Be prepared to intubate early, the patency of the airway can decline quickly and without warning. If there is any concern for burns to face/neck or smoke inhalation, consider taking control of the airway early. Review the rule of 9s and the parkland formula to direct your large volume fluid resus.  Remember the parkland formula directs you to use 4 mL x %TBSA x weight (kg).  Half in the first 8 hours and the second half over the next 16 hours.  Given the large volume here it’s probably best to use LR or another balanced solution. Do a thorough trauma eval to make sure you don’t miss any other injuries and be sure to watch for developing compartment syndrome And last, consider the need to treat for CO and/or cyanide poisoning.  Poor cardiac function, cardiac arrest or a high lactate can be clues to cyanide poisoning and just start 100% O2 while you wait for a co-ox, since CO tox is pretty likely.

This week we discuss 3 articles recently reviewed in our conference - LOV-ED study, Validation of Step-By-Step and Therapeutic Hypothermia. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Episode_99_0_Final_Cut.m4a Download Leave a Comment Tags: ARDS, Cardiac Arrest, Lung Protective Ventilation, Mechanical Ventilation, OHCA, Step-By-Step Protocol, Therapeutic Hypothermia, TTM Show Notes Take Home Points The step-by-step approach to managing febrile infants is a reliable decision instrument to identify patients at low risk for invasive bacterial infections. Caution in the group of patients 22-28 days of age. The LOV-ED study shows an association between employing a lung-protective ventilation strategy in the ED and decreased complications from mechanical ventilation. Best available evidence says that we should embrace this approach in the ED. Cooling to 33 degrees is no better than cooling to 36 degrees. However, shooting 36 degrees is more difficult than we may have thought. We have to continue to be vigilant about maintaining patients in the target temperature range and avoiding fever.

This week we discuss the rare but life-threatening methemoglobinemia with a focus on recognition and use of the antidote. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Episode_97_0_Final_Cut.m4a Download 2 Comments Tags: Methemoglobin, Toxicology Show Notes Take Home Points MetHb –emia occurs as a results of various medications including amyl nitrite, dapsone, nitroprusside, phenazopyridine, sodium nitrite and topical anesthetics like benzocaine Patients will present with cyanosis, short of breath, fatigue, dizziness, weakness and ultimately CNS depression and death at higher concentrations. If you have a cyanotic/hypoxic patient that does not respond to supplemental oxygen, be concerned for MetHb and send a co-oximetry panel. If the level is 25% or the patient is symptomatic, you will treat with the antidote methylene blue given as a bolus of 1-2 mg/kg over 5 minutes And as always, make sure to call your local poison center to get your toxicologists involved. They can help with dosing, and they are also an important player of the public health component in cases such as these, to make sure this is an isolated incident and we don’t have a repeat of the 11 blue men situation.

This week we do a brief review on recognizing CO monoxide poisoning and expertly managing it. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Episode_96_0_Final_Cut.m4a Download Leave a Comment Tags: CO, Inhaled Toxins, Toxicology Show Notes Take Home Points CO poisoning happens most often from common are accidental exposures from faulty home heaters, camp stoves and indoor use of gas powered generators, structure fires and intentional exposure like in suicide attempts. Patients with a mild exposure will present with symptoms like headache, nausea, vomiting, dizziness, vision blurring, palpitations, confusion or myalgias.  More severe exposures may produce Altered mental status. seizures, coma, dysrythmias, myocardial ischemia, metabolic acidosis, syncope and vital sign abnormalities including hypotension and, eventually, cardiac arrest. To help distinguish the vague symptoms of a patient who may have chronic exposure ask about things like whether symptoms improve in different environments or whether they have sick pets, as human viral illness generally don’t affect our dogs and cats. If you’re concerned about CO send a co-ox panel.  City dwellers may have a baseline carboxyhemoglobin of 1-2% and smokers around 6-10% but others should really have no carboxyhemoglobin. Treatment is supplemental O2 which can be stopped when symptoms improve.  For severe symptoms and for pregnant patients, consider hyperbarics to prevent long term sequelae and to protect the fetus.  As always, consider discussing the case with your local poison center to help decide whether a patient warrants transfer for hyperbarics.

This week we discuss some of the many dialysis-related emergencies we frequently see in the ED. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Podcast_Episode_92_0_Final_Cut.m4a Download One Comment Tags: Dialysis, ESRD, Nephrology Show Notes Take Home Points On any dialysis patient, make sure to do a good assessment of their access site.  If it’s a fistula, assess for a thrill, for any warmth/induration/erythema and make sure they have distal sensation and perfusion.  If it’s a catheter, evaluate for any signs of infection—so warmth, erythema or discharge. Bleeding is a big concern. If the patient is bleeding from their access, start with direct pressure to the bleeding site, then move on to topical thrombotic agents and if needed throw a figure 8 stitch with a 5-0 proline on a non-cutting needle. Peritoneal dialysis patients are at risk for bacterial peritonitis.  In a PD patient that appears infected, get a peritoneal fluid sample and start antibiotics Dialysis patients are susceptible to dialysis disequilibrium syndrome which can present as altered mental status, focal neurological deficits or even frank coma or seizures after dialysis.  Make sure to consider a broad differential in these patients and start with a solute load such as an amp or two of D50 while starting your work up.

Patients typically present with purulent nasal discharge and facial pain or other URI symptoms. The vast majority of patients with acute rhino sinusitis will be viral in nature and will not benefit from antibiotics Patients with prolonged symptoms, more than 7-10 days, without improvement or continued fevers past 2-3 days should be considered for antibiotic treatment as should those who are immunocompromised.

This week we discuss the ED management of anterior and posterior epistaxis. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Podcast_Episode_89_0_Final_Cut.m4a Download 3 Comments Tags: ENT, Epistaxis, Nose Bleeds, TXA Show Notes Take Home Points The first step is managing epistaxis is solid pressure.  This means holding a tight pinch just distal to the nasal bones and hold, without peaking, for at least 5 minutes.  This will stop a good deal of the bleeding. If you need to do more, start by soaking gauze in either oxymetazoline or epinephrine, mix in some lidocaine to help with anesthesia, pack the nare with that and add on some compression.  Hope fully this stops the bleeding enough that you can see a good bleeder and perform cautery. Third line of treatment would be to try some soaked gauze, but this time with TXA. Can’t hurt to try! And then last resort is of course packing. Here make sure the patient is anesthetized with some lidocaine, lubricate the packing well and apply horizonally, no vertically as we are often tempted.

This approach quickly drops the rhythm into 1 of 4 boxes and makes rhythm determination much easier Each of those 4 categories has a small set of rhythms included. Narrow and irregular - AF, Aflutter with variable block or MFAT. Narrow and regular - SVT or Aflutter. Wide and irregular - Torsades, VF, AF with aberrancy or a BBB. Wide and regular - VTach, SVT with aberrancy or SVT with a BBB. If you see wide and regular, the top 3 diagnoses are VT, VT and VT.

Ketorolac has an analgesic ceiling effect lower than you may have thought.  When comparing IV doses of 10mg, 15mg and 30mg they found no difference in analgesic effect.  Given the risks of side effects may increase with higher doses, you may want to stick to the lower 10mg dose.

Theoretically, this alloimmunization can occur even in early pregnancy While anti-D immune globulin has clearly been shown to be beneficial in preventing alloimmunization in 2nd and 3rd trimester pregnancy, there is no evidence supporting use specifically in the 1st trimester Despite the absence of evidence, RhoGam administration has become routine in many places. At this time, it’s advisable to follow local practice patterns regarding which patients should be given RhoGam. References ACOG Practice Bulletin. Prevention of Rh D Alloimmunization.

This week we discuss three common complications of delivery: cord prolapse, nuchal cord and shoulder dystocia. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Podcast_85_0_Final_Cut.m4a Download Leave a Comment Tags: Cord Prolapse, Nuchal Cord, Obstetrics, Shoulder Dystocia Show Notes Take Home Points If you have a patient with a cord prolapse, elevate the presenting part to take pressure off the cord, place the patient in trendelenburg and fill the bladder. Then, redline it to the OR for a c-section. Nuchal cord is common but likely not too dangerous. Just gently unwrap the umbilical cord and the fetus should be just fine Shoulder dystocia isn’t common but it’s a true emergency as the fetus can suffer severe hypoxia or death. You’ve got a bout 5 minutes to deliver. Immediately call for help from OB, place a foley catheter to drain the bladder and place the mom’s legs so that her knees are pressed into her chest. This helps to open up the pelvis and give more room for the shoulder to be delivered. If that doesn’t work, you can try the wood’s screw maneuver or place the mom on all 4s. If you’ve got an OR ready, pushing the head back in is also an option but only if you have an OR available Read More Core EM: Shoulder Dystocia emDocs: The Complicated Delivery: What You Can Do Del Portal DA et al.  Emergency department management of shoulder dystocia.  J Emerg Med. 2014 Mar;46(3):378-82.

This week we look at TBI and discuss some of the pitfalls and pearls in early management of traumatic ICH. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Podcast_84_0_Final_Cut.m4a Download 2 Comments Tags: Head Injury, Hyperosmolar Therapy, ICH, Resuscitation, RSI, TBI, Trauma Show Notes Take Home Points If you get a heads up from EMS on an incoming trauma, take the lead time you get to clearly delineate everyone’s roles to help ensure the resuscitation runs smoothly. In the severe TBI patient, the key is in preventing secondary injury to the brain. We do this by guarding against hypoxia, hypercarbia, hypotension and aspiration. Max your pre-ox, get the ETT in quickly to prevent oxygenation and ventilation issues and keep the head up if possible Hypotension is rarely seen in isolated head trauma. If the patient is or becomes hypotensive, reassess for any sources of hemorrhagic shock that may have been missed and consider whether the meds you gave may have caused the problem. Hypertension is much more common and despite extensive research, we haven’t shown that dropping the patient to normal levels is beneficial. Keeping the SBP < 180 seems reasonable but check your local protocol as well. If the patient’s ICP spikes or your concerned about herniation, administer mannitol or hypertonic saline and get your neurosurgeon to the bedside since the patient is gonna need decompression Finally, make sure to reverse any anticoagulant the patient may have on board as this will hopefully prevent hematoma expansion.

This week we discuss the ED management of seizures focusing on treatment and workup particularly of a 1st seizure episode. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Podcast_Episode_82_0_Final_Cut.m4a Download Leave a Comment Tags: Neurology, Seizure, Status Epilepticus Show Notes Take Home Points Get a detailed history to tease out whether the patient had a seizure or a syncopal event. Regardless, get an EKG on 1st time seizures in case it was actually syncope. BZDs are first line therapy for seizure termination. If you don’t have IV access, go with 10 mg of midazolam or 2-4 mg of lorazepam IM Always review the 5 main categories for causes of seizures in order to make sure you’re not missing anything. Those categories once again are vital sign abnormalities, CNS infections, toxic/metabolic issues, CNS space occupying lesions including masses and bleeds and finally epilepsy. In patients with a first time seizure without a particular cause and return to baseline neurologic status, there’s unlikely to be any benefit to a NCHCT or to starting an AED. Scheduling close follow up with a neurologist is very reasonable. The key is to do a thorough examination and make sure you’re not missing a subtle abnormality. Finally, in status epilepticus hit the patient with 2-3 hefty doses of BZDs and if the seizure is still ongoing, strongly consider moving to propofol and intubation in order to rapidly control the seizure activity.

This week we feature a short primer on penetrating chest trauma focusing on circulation first over airway and breathing. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Podcast_Episode_80_0_Final_Cut.m4a Download Leave a Comment Tags: ED Thoracotomy, EFAST, Resuscitative Thoracotomy, Trauma, Ultrasound Show Notes Take Home Points Don’t rush to the airway. In most situations, you have some time so resuscitate before you intubate. Give blood products and get the BP up a bit to give yourself a little better physiologic situation in which to intubate. Start your massive transfusion immediately if the patient is shocked. There’s always a delay in getting products but the earlier you start, the shorter the delay. Include US in your primary survey. Your E-FAST should start with the cardiac window, then go to the lungs and then, finally, the abdomen. This order focuses on finding pathology you can fix immediately. If the patient is shocked and peri-arrest or recently lost vitals, open the chest and look for a fixable injury. Start with opening the pericardium to relieve tamponade, identify and repair cardiac wounds and cross clamp the aorta.

This week we discuss facial trauma and the disasters it can cause to your airway management. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Podcast_Episode_79_0_Final_Cut.m4a Download 2 Comments Tags: Airway, Cricothyroidotomy, RSI, Trauma Show Notes Take Home Points In a patient with significant head and neck trauma, EACH step of the airway management can be more difficulty. BVM may be hard, LMA may be hard, RSI may be hard, so don’t be afraid to ask for help early. Decide whether the patient has an actual obstruction of their airway. If they are obstructed above the larynx, don’t bother with your usual airway maneuvers, go directly to the surgical airway. When you do attempt RSI, have double suction and multiple airway techniques set up. This is the time to have your friend standing at your side, scalpel in hand and ready to move directly down the difficult airway algorithm if trouble arises. Finally, consider keeping the patient awake and preserving their own respiratory drive as it may give you more time to secure the airway.
