Podcast 1005: Balanced Fluid vs Normal Saline in Pediatric Patients
Emergency Medical Minute
Contributor: Aaron Lessen, MD Educational Pearls: There has long been many questions about which IV fluid is best for ED resuscitation Multiple adult studies have shown no clear benefit of balanced fluid vs normal saline A large pediatric randomized clinical trial published in April compared balanced fluid vs normal saline in children with septic shock The study included about 9,000 patients from 47 emergency departments in five countries Patients with septic shock were randomized to receive either balanced fluid or normal saline The primary outcome was adverse kidney event...

Podcast 1004: Sinus Arrest Post TAVR
Emergency Medical Minute
Contributor: Taylor Lynch, MD Educational Pearls: Conduction abnormalities are a common and clinically significant complication in patients who undergo transcatheter aortic valve replacement (TAVR) Clinical Features The most common abnormalities include high grade AV block and new onset LBBB Due to the close proximity of the aortic annulus to the AV node and His-Purkinje system More common in males, the elderly, and those with pre-existing conduction disease (RBBB or LBBB) Sinus pauses and sinus arrest are a rare post-TAVR rhythm disturbances Temporary...

Podcast 1003: Nasal Intubation
Emergency Medical Minute
Contributor: Alec Coston, MD Educational Pearls: What are nasal intubations and when do we use them? Nasal intubations function similarly to oral intubations with the end goal of passing an endotracheal tube (ETT) through vocal cords and into the trachea to allow for a patent and secure airway, but differ in the main access point for the ETT (nare v.s. mouth). Nasal Intubations are seldom preferred to oral intubations as they carry risk for inducing bleeding from trauma to the nasal passages. Indications for nasal intubations include: Anatomical abnormalities that may make...

Podcast 1002: Elder Agitation
Emergency Medical Minute
Contributor: Aaron Lessen, MD Educational Pearls: What are the common causes of agitation in the elderly? Baseline dementia causing a behavioral disturbance Delirium precipitated by an acute medical problem such as a UTI, pneumonia, overdose/side effect of home medications, urinary retention, constipation, pain, hypoxia, electrolyte abnormality, etc. Exacerbation of a primary psychotic condition such as schizophrenia or bipolar disorder. What environmental changes can help reduce agitation? Maintain a quiet, calm, uncluttered environment Dim the lights Ensure the patient has their glasses,...

Podcast 1001: Acute Intermediate Risk Pulmonary Embolism
Emergency Medical Minute
Contributor: Aaron Lessen, MD Educational Pearls: Patients with pulmonary embolism (PE) are divided into three risk categories Low risk (non-massive PE): patients are stable Treatment: prescribe anticoagulants and discharge home Intermediate risk (submassive PE): patients are stable but display evidence of clot burden such as elevated troponin, elevated BNP, and/or right heart strain Treatment is controversial High risk (massive PE): patients are unstable with hypotension, hypoxia, and/or respiratory distress Treatment: IV thrombolysis to prevent decompensation A recent randomized...

Podcast 1000: Cool Water
Emergency Medical Minute
Contributor: Aaron Lessen, MD Educational Pearls: Burns range in complexity from minor first-degree burns to more severe full-thickness burns. Initial basic burn management: Run the burn under cool running water for 20 minutes. Do not scrub the skin. Do not use ice water. Ideally initiated as soon as possible, but no later than 3 hours after injury. Applicable to all burns ranging from superficial to full thickness. Then apply a non-adherent dressing or sterile gauze. Can be done at home or upon presentation to the emergency department. These steps decrease pain and minimize tissue damage....

Podcast 999: Right vs Left Internal Jugular Access
Emergency Medical Minute
Contributor: Travis Barlock, MD Educational Pearls: What is an internal jugular catheter (IJ) and when do we use it? IJs are catheters that can be placed in either the left or the right internal jugular vein to provide central venous catheter (CVC) access. CVCs can be placed in other locations other than the internal jugular vein (i.e. subclavian vein or femoral veins). IJs are used when the patient may require long-term venous access or have to receive hyperosmolar solutions (such as solutions with high glucose content for parenteral nutrition); solutions with extreme pHs (<5 or >9);...

Podcast 998: Delayed Intubation After an Overdose
Emergency Medical Minute
Contributor: Aaron Lessen, MD Educational Pearls: How long do we need to watch patients with a presumed overdose who were treated with naloxone in the field? A 2025 study in the Annals of Emergency Medicine took a look at this question Methods Prospective, multi-institutional cohort study Included ED patients with suspected acute opioid overdose with biologic testing to confirm substances. This paper performed a secondary analysis evaluating the risk of “delayed intubation,” defined as intubation occurring >4 hours after ED arrival. Results 1,591 patients with presumed opioid...

Educational pearls:
- Clinical management of COVID-19 is rapidly evolving, relying on case reports and clinical experience
- In just a month, the consensus around management of COVID patients with severe hypoxia has shifted from an early intubation strategy to other, non-invasive means
- Intubating early can quickly consume ventilator resources, require increased intensive care monitoring, and likely leads to longer hospital stays and once COVID patients are intubated, extubation can take days to weeks.
- In Italy, ventilator supplies were depleted leading to the use of helmet CPAP machines, which appeared to be effective in management of respiratory distress in COVID, though not available for use in the US
- Non-invasive ventilation such as CPAP/BiPAP is thought to increase risk to staff for infection via aerosolization, and has often been avoided in COVID patients
- High flow nasal cannulas appear to pose less of a risk of aerosolization of viral particles (especially when a surgical mask is placed over the patient’s nose, mouth and apparatus)
- Anecdotal evidence from NYC has shown success allowing conscious patients to maintain hypoxia on HFN, where they will self prone to help with lung recruitment, and seemingly do well despite persistent saturations in the 80s or less
- Hospitals around the country are moving away from the intubate early methodology in favor of high flow oxygen therapy as long as they are not having issues with work of breathing or other complications
- The pathophysiology of respiratory distress and hypoxia in COVID patients is evolving as well, and some presentations appear similar to disease processes such as high altitude pulmonary edema (HAPE) rather than acute respiratory distress syndrome (ARDS), in that patients are quite well appearing despite phenomenally low oximetry readings.
-
- These select patients appear to be excellent candidates for non-invasive means rather than an early intubation strategy
Editor’s note: do not take lightly that intubation is one of the highest risk aerosolization generating procedures, along with many peri-intubation procedures like suctioning, BVM, etc.
