Contributor: Taylor Lynch MD Educational Pearls Hypothermia is defined as a core body temperature less than 35 degrees Celsius or less than 95 degrees Fahrenheit  Mild Hypothermia: 32-35 degrees Celsius Presentation: alert, shivering, tachycardic, and cold diuresis Management: Passive rewarming i.e. remove wet clothing and cover the patient with blankets or other insulation Moderate Hypothermia: 28-32 degrees Celsius Presentation: Drowsiness, lack of shivering, bradycardia, hypotension Management: Active external rewarming Severe Hypothermia: 24-28 degrees Celsius Presentation: Heart block, cardiogenic shock, no shivering Management: Active external and internal rewarming Less than 24 degrees Celsius Presentation: Pulseless, ventricular arrhythmia Active External Rewarming Warm fluids are insufficient for warming due to a minimal temperature difference (warmed fluids are maintained at 40 degrees vs. a patient at 30 degrees is not a large enough thermodynamic difference) External: Bear hugger, warm blankets Active Internal Rewarming Thoracic lavage (preferably on the patient’s right side) Place 2 chest tubes (anteriorly and posteriorly); infuse warm IVF anteriorly and hook up the posterior tube to a Pleur-evac Warms the patient 3-6 Celsius per hour Bladder lavage Continuous bladder irrigation with 3-way foley or 300 cc warm fluid Less effective than thoracic lavage due to less surface area Pulseless patients ACLS does not work until patients are rewarmed to 30 degrees High-quality CPR until 30 degrees (longest CPR in a hypothermic patient was 6 hours and 30 minutes) Give epinephrine once you reach 35 degrees, spaced out every 6 minutes ECMO is the best way to warm these patients up (10 degrees per hour) Pronouncing death must occur at 32 degrees or must have potassium > 12 References 1. 2005 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care - Part 1: Introduction.

Contributor: Jared Scott MD Educational Pearls: Croup is a respiratory condition typically caused by a viral infection (e.g., parainfluenza). The disease is characterized by inflammation of the larynx and trachea, which often leads to a distinctive barking cough. A common treatment for croup is the powerful steroid dexamethasone, but it can take up to 30 minutes to start working. A folk remedy for croup is to take the afflicted child outside in the cold to help them breathe better, but does it really work? A 2023 study in Switzerland, published in the Journal of Pediatrics, investigated whether a 30-minute exposure to outdoor cold air could improve mild to moderate croup symptoms before the onset of steroid effects. The randomized controlled trial included children aged 3 months to 10 years with croup. After receiving a single-dose oral dexamethasone, participants were exposed to either outdoor cold air or indoor room air. The primary outcome was a decrease in the Westley Croup Score (WCS) by at least 2 points at 30 minutes. The results indicated that exposure to outdoor cold air, in addition to dexamethasone, significantly reduced symptoms in children with croup, especially in those with moderate cases.

Contributor: Aaron Lessen MD Educational Pearls: Does the size of a blood pressure (BP) cuff matter? A recent randomized crossover trial revealed that, indeed, cuff size can affect blood pressure readings Design 195 adults with varying mid-upper arm circumferences were randomized to the order of BP cuff application: Appropriate Too small Too large Individuals had their mid-upper arm circumference measured to determine the appropriate cuff size Participants underwent 4 sets of triplicate blood pressure measurements, the last of which was always with the appropriately sized cuff Results In individuals requiring a small cuff, the use of a regular cuff resulted in blood pressure readings 3.6 mm Hg lower than with the small cuff In individuals requiring large cuffs, the use of a regular cuff resulted in pressures 4.8 mm Hg higher than with the large cuffs In individuals requiring extra-large cuffs, the use of a regular cuff resulted in pressures 19.5 mm Hg higher than with extra-large cuffs Conclusion Miscuffing results in significantly inaccurate blood pressure measurements It is important to emphasize individualized BP cuff selection References 1.

Contributor: Aaron Lessen MD Educational Pearls: Is the adage, “GCS of 8, you’ve got to intubate” accurate? A recent study published in the November 2023 issue of JAMA attempted to answer this question. Design Multicenter, randomized trial, in France from 2021 to 2023. 225 patients experiencing comatose in the setting of acute poisoning were randomly assigned to either a conservative airway strategy of withholding intubation or “routine practice” of much more frequent intubation. The primary outcome was a composite endpoint including in-hospital death, length of intensive care unit stay, and length of hospital stay. Secondary outcomes included adverse events from intubation and pneumonia within 48 hours. Results Results showed that in the intervention group (with intubation withholding), only 16% of patients were intubated, compared to 58% in the control group. No in-hospital deaths occurred in either group. The intervention group demonstrated a significant clinical benefit for the primary endpoint, with a win ratio of 1.85 (95% CI, 1.33 to 2.58). The conservative airway management strategy also saw a statistically significant decrease in adverse events from intubation and pneumonia. Conclusion Among comatose patients with suspected acute poisoning, a conservative strategy of withholding intubation was associated with a greater clinical benefit. This suggests that a judicious approach to intubation is appropriate in many other settings and clinicians should rely on more than the GCS to make this decision.

Contributor: Kiersten Williams MD, Travis Barlock MD, Jeffrey Olson MS2 Summary: In this episode, Dr. Travis Barlock and Jeffrey Olson meet in the studio to discuss a clip from Dr. Williams’ talk at the “Laboring Under Pressure, Managing Obstetric Emergencies in a Global Setting” event from May 2023. This event was hosted at the University of Denver and was organized with the help of Joe Parker as a fundraiser for the organization Health Outreach Latin America (HOLA). Dr. Kiersten Williams completed her OBGYN residency at Bay State Medical Center and practices as an Obstetric Hospitalist at Presbyterian/St. Luke’s Medical Center in Denver, Colorado. During her talk, Dr. Williams walks the audience through the common causes and treatments for post-partum hemorrhage (PPH). Some important take-away points from this talk are: The most common causes of PPH can be remembered by the 4 T’s. Tone (atony), Trauma, Tissue (retained placenta), and Thrombin (coagulopathies). AV malformations of the uterus are probably underdiagnosed. Quantitative blood loss is much more accurate than estimated blood loss (EBL). The ideal fibrinogen for an obstetric patient about to deliver is above 400 mg/dl - under 200 is certain to cause bleeding. Do not deliver oxytocin via IV push dose, it can cause significant hypotension. Tranexamic Acid is available in both IV and PO and can be administered in the field. The dose is 1 gram and can be run over 10 minutes if administered via IV. It is best if used within 3 hours of delivery. When performing a uterine massage, place one hand inside the vagina and one hand on the lower abdomen. Then rub the lower abdomen like mad. A new option for treating PPH is called the JADA System which is slimmer than a Bakri  Balloon and uses vacuum suction to help the uterus clamp down.* Another option for a small uterus is to insert a 60 cc Foley catheter. In an operating room, a B-Lynch suture can be put in place, uterine artery ligation can be performed, and as a last resort, a hysterectomy can be done. *EMM is not sponsored by JADA system or the Bakri balloon.

Contributor: Meghan Hurley MD Educational Pearls: What is a nerve block? A nerve block is the medical procedure of injecting anesthetic into the area around a nerve to block pain signals.  They are typically done with ultrasound guidance. Are nerve blocks effective? Most of the information we have about nerve blocks is extrapolated from fascia iliaca blocks. This nerve block targets the fascia iliaca compartment, which contains the femoral, lateral femoral cutaneous, and obturator nerves. These blocks are commonly done for hip fractures to help stabilize the patient while awaiting surgical repair. The data for these types of injections is strong. They decrease pain, they decrease total morphine equivalents needed while a patient is in the hospital, they help mobilize patients earlier and start physical therapy earlier, and they help patients leave the hospital about a day earlier. What is an example of an agent that can be used? Bupivacaine. A long acting amide-type local anesthetic. It works best when paired with epinephrine which causes local vasoconstriction and allows the bupivaciaine to bathe the nerve for longer. It gives 5-15 hours of anesthesia (complete sensation loss), and up to 30 hours of analgesia (pain loss). What’s an example of another block that can be done? An Erector Spinae Plane (ESP) block is performed in the paraspinal fascial plane in the back. This can be used for pain around the ribs and before a variety of medical procedures including a Nuss procedure, thoracotomies, percutaneous nephrolithotomies, ventral hernia repairs, and even lumbar fusions. What is one potential complication of a nerve block? Local Anesthetic Systemic Toxicity (LAST). There are three ways this can happen: 1) Using too much total anesthetic (Maximum dose of bupivacaine is 2.5 mg/kg). 2) Too much anesthetic is injected into a confined space which then gets absorbed into the venous system. 3) Injecting directly into the vasculature by mistake. What are the signs that this complication has occurred? Perioral tingling Stupor Coma Seizures What can that cause? Cardiovascular collapse How is that treated? Intralipid AKA Soybean Oil, or “lipid emulsion” should be given as a bolus followed by a drip. These patients need to be admitted. Bolus 1.5 ml/kg (lean body mass) intravenously over 1 min (max ~100 ml). Continuous infusion at 0.25 mL/kg/min. Max dosing in the first 30 minutes is around 100 ml/kg. Fun fact: Patients being treated for LAST with intralipid cannot undergo general anesthesia because the intralipid will impact the anesthesia drugs.

Contributor: Aaron Lessen MD Educational Pearls: How is the severity of a stroke assessed? Strokes are assessed by the NIH Stroke Scale (NIHSS), this scale has different tasks, such as asking the person to repeat words, move their arms, or follow simple instructions. The maximum score is 42 but any score over 21 is considered severe. What would qualify as a minor storke? NIH This could be achieved with minor symptoms such as numbness Should patients with minor strokes be given thrombolytics? A new study in JAMA published in June of 2023 sought to answer this question. This study compares the effectiveness of dual antiplatelet therapy (DAPT) with intravenous thrombolysis in patients with minor non-disabling acute ischemic stroke. The research involved 760 participants in China, and the primary measure was an excellent functional outcome at 90 days. The results showed that DAPT was non-inferior to intravenous alteplase, with 93.8% of patients in the DAPT group and 91.4% in the alteplase group achieving an excellent functional outcome. The study suggests that DAPT could be a viable alternative to intravenous thrombolysis for patients with minor non-disabling strokes within 4.5 hours of symptom onset. Additionally, the incidence of symptomatic intracerebral hemorrhage was low in both groups. References 1.
