Contributor: Aaron Lessen, MD Educational Pearls: Quick background info Cardiac arrest is when the heart stops pumping blood for any reason. This is different from a heart attack in which the heart is still working but the muscle itself is starting to die. One cause of cardiac arrest is when the electrical signals are very disrupted in the heart and start following chaotic patterns such as Ventricular tachycardia (VTach) and Ventricular fibrillation (VFib) One of the only ways to save a person

Contributor: Ricky Dhaliwal, MD Educational Pearls: Ketorolac and ibuprofen are NSAIDs with equivalent efficacy for pain in the emergency department Oral ibuprofen provides the same relief as intramuscular ketorolac IM ketorolac is associated with the adverse effect of a painful injection IM ketorolac is slightly faster in onset but not significant Studies have assessed the two medications in head-to-head randomized-controlled trials and found no significant difference in pain scores

Emergency Medical Minute ·

2025/01/20

Contributor: Aaron Lessen, MD Educational Pearls: If a patient sustains a cut, the provider has several options on how to close the wound. If they choose to suture the wound closed, it involves needles both in the form of injecting numbing medication (lidocaine) as well as with the suture itself. Other techniques are “needleless,” like closing the wound with adhesive strips (Steri-Strips) or skin adhesive (Dermabond). But which method is best? A recent study looked to compare guardian-perceived

2024/12/23

Contributor: Ricky Dhaliwal MD Educational Pearls: Etomidate was previously the drug of choice for rapid sequence intubation (RSI) However, it carries a risk of adrenal insufficiency as an adverse effect through inhibition of mitochondrial 11-β-hydroxylase activity A recent meta-analysis analyzing etomidate as an induction agent showed the following: 11 randomized-controlled trials with 2704 patients Number needed to harm is 31; i.e. for every 31 patients that receive etomidate for

Contributor: Aaron Lessen MD Educational Pearls: Pregnant patients at high risk of cardiac arrest, in cardiac arrest, or in extremis require special care A useful mnemonic to recall the appropriate management of critically ill pregnant patients is TOLDD T: Tilt the patient to the left lateral decubitus position This position relieves pressure exerted from the uterus onto the inferior vena cava, which reduces cardiac preload If the patient is receiving CPR, an assistant should displace the

2024/12/09

Contributor: Travis Barlock MD Educational Pearls: What is the ST segment? The ST segment on an ECG represents the interval between the end of ventricular depolarization (QRS) and the beginning of ventricular repolarization (T-wave). It should appear isoelectric (flat) in a normal ECG. What if the ST segment is elevated? This is evidence that there is an injury that goes all the way through the muscular wall of the heart (transmural) This is very concerning for a heart attack (STEMI) but

Episode 931: Naloxone in Cardiac Arrest

Emergency Medical Minute ·

2024/11/18

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
