Emergency Medical Minute

Contributor: Alec Coston MD Educational Pearls: Causes of seizures in a fairly well-appearing child with diarrhea: Electrolyte abnormalities: hypocalcemia, hyponatremia Also hyperkalemia which causes arrhythmias and syncope - can appear like seizures Hypoglycemia If the child has diarrhea and appears very sick, differential diagnosis may include: Hemolytic uremic syndrome (HUS): simultaneous occurrence of microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury Typically caused by Shiga-like toxin producing Escherichia coli (also known as EHEC, or...

Emergency Medical Minute

Contributor: Aaron Lessen MD Educational Pearls: Induction agent selection during rapid sequence intubation involves accounting for hemodynamic stability in the post-intubation setting Many emergency departments use ketamine or etomidate A recent study sought to explore the rates of post-induction hypotension of ketamine compared with propofol Single center retrospective cohort study of patients between 2018-2021 Ketamine and propofol were both significantly associated with post-induction hypotension Ketamine adjusted odds ratio = 4.50 Propofol adjusted odds ratio = 4.88 50%...

Episode 931: Naloxone in Cardiac Arrest show art Episode 931: Naloxone in Cardiac Arrest

Emergency Medical Minute

Contributor: Aaron Lessen MD Educational Pearls: Can opioids cause cardiac arrest? Opioids can cause respiratory suppression and the subsequent low oxygen levels can lead to arrhythmias and eventually cardiac arrest. In 2023, 17% of out-of-hospital cardiac arrests (OHCA) were attributable to opioids. Given that this is a rising cause of cardiac arrest, should we just treat all cardiac arrest with naloxone (Narcan)? Naloxone is correlated with an increased chance of return of spontaneous circulation (ROSC) Additionally, a wide variety of individuals can be exposed to opioids and...

Emergency Medical Minute

Contributor: Taylor Lynch, MD Educational Pearls: What is neutropenic fever? Specific type of fever that is seen in cancer patients and other patients with impaired immune systems These patients are highly susceptible to infection Typically occurs 7-10 days after the last chemotherapy dose, this is when the immune system is the weakest It is useful to know the specific type of malignancy. For example, heme malignancies (ALL, AML, etc.) have more intense chemo and are at higher risk of neutropenic fever To qualify as a neutropenic fever, a patient must have one recorded temperature...

Emergency Medical Minute

Contributor: Aaron Lessen, MD Educational Pearls: Pediatric case study where the child’s tongue was stuck in the opening of a hard plastic drink lid Entrapment restricts circulation which causes fluid to build and the tongue becomes more edematous with time There is a risk of ischemia with prolonged entrapment Initially tried 2% viscous lidocaine for analgesia and lubricant The ER recognized that this mucosal, edematous tongue could benefit from the trick for ostomies and rectal prolapses → table sugar! Sugar granules absorb water which decreases tissue edema This option...

Educational Pearls:

  • Insulin pumps provide a continuous infusion of fast-acting insulin using a basal rate and bolus prior to meals
  • Some connect to a continuous glucometer but often blood glucose needs to be checked manually
  • Hypoglycemia is rarely due to a malfunctioning pump - there is usually an another external factor
  • Hyperglycemia can be caused by underdosing, illness, pump malfunction or expired insulin
  • The pump can be used to give a bolus of insulin in the emergency department if necessary
  • Stopping the  device can be done manually on the device or disconnecting it from the tubing attachment - do not remove the tubing from the skin site if possible
