Noninvasive respiratory support is among the greatest recent advances in critical care. When used properly, these techniques may facilitate avoidance of intubation, reduced length of stay, and better outcomes. Unfortunately, our knowledge of exactly how to use these devices remains woefully incomplete. In particular, there are rather few RCTs directly comparing BiPAP versus HFNC. In […]
EMCrit 262 – Midlines – Part 1
Midlines can change your vascular access practice
EM Nerd-The Case of the Adjacent Contradictions
There has been a long-standing debate in the fields of emergency medicine and critical care regarding the ideal paralytic agent to use during RSI, rocuronium or succinylcholine. This dispute, has even developed slogans such as Roc Rocks, Sux Sucks as one side attempts to definitively proclaim its superiority through witty aspersions. But up until now […]
PulmCrit- Nebulized nitroglycerin: The stealth pulmonary vasodilator hiding under your nose?
Recently Sara Crager released a video on EM-RAP recommending inhaled milrinone or nitroglycerin as an emergency therapy for massive pulmonary embolism (in case you don’t have access to EM-RAP, an audio clip from the video is below). This is the first that I’ve heard of using inhaled nitroglycerin. It seems like a pretty neat idea, […]
IBCC chapter & cast – Acute promyelocytic leukemia
Acute promyelocytic leukemia (APL) is a unique leukemia, with particular importance to resuscitationists. Unlike most leukemias, the highest rate of mortality occurs at the time of diagnosis (a phenomenon known as “early deaths”). If patients are able to survive the initial phase of illness, the cure rate is extremely high (>90%). Aggressive support in the […]
Pulmcrit Wee- Rare catastrophic complications, heparin, and succinylcholine: Sometimes excellent is the enemy of perfect.
A multi-center RCT was released yesterday comparing rocuronium versus succinylcholine. It’s a thoroughly uninformative study, so at first I wasn’t planning to write about it. But then I realized that the study, in its very myopia, is a good illustration of our problem with rare catastrophic complications. warmup: heparin infusions and rare catastrophic complications A […]
PulmCrit- Furosemide failure: should we add metolazone, IV chlorothiazide, or… tolvaptan?!? (3T trial)
Diuretics are a bit like vasopressors. We use them all the time, so we feel that we know them pretty well. However, the amount of RCT-level evidence on them is shockingly low. So, whenever a RCT on diuretics shows up, it’s worth careful examination. the 3T trial: basics This is a single-center, double-blind trial involving […]
EMCrit 261 – Thrombolysis during Cardiac Arrest
Who should we thrombolyse during cardiac arrest?
IBCC chapter & cast – Hyponatremia
Since finishing my training, I’ve learned three new techniques for the management of hyponatremia: the DDAVP clamp, use of hypertonic bicarbonate, and oral urea. Meanwhile, I’ve removed the use of vaptans from my practice and grown more comfortable using 3% saline. The confluence of these factors has transformed hyponatremia from something scary to something which […]
PulmCrit- Hyperdiuresis: Using hypertonic saline to facilitate diuresis
Using hypertonic saline to facilitate diuresis seems counterintuitive, paradoxical even. Volume overloaded patients have excess sodium. Why should we give them more? Let’s start by trying to understand the underlying physiology. hypochloremia may cause renal sodium retention We generally don’t pay much attention to serum chloride levels. Chloride is often viewed as a leftover, an […]
IBCC chapter & cast – Hypokalemia
Hypokalemia is one of the most commonly encountered electrolyte abnormalities in critically ill patients, and perhaps the most commonly intervened upon abnormality. Although this is mundane, it behooves us to understand it fully and treat it optimally. Even minor nuances in treatment could potentially have significant impact, given how commonly hypokalemia is managed. The IBCC […]
EMCrit 260 – Thoughts on the NEJM Acute Upper Airway Obstruction Review
Thoughts on a recent NEJM review on upper airway obstruction
PulmCrit- All 2nd line conventional anti-epileptics are equally good… or equally bad?
The management of generalized convulsive status epilepticus remains in perpetual status controversius. There is consensus that the front-line agent should be a benzodiazepine, but little agreement beyond that. The much-awaited ESETT trial is a multi-center RCT comparing three anti-epileptic agents for ongoing status epilepticus (levetiracetam, fosphenytoin, and valproate). This trial will be the highest-quality evidence […]
IBCC chapter & cast – Brain death
Brain death determination and support of a potential organ donor are core topics in critical care. These topics aren’t particularly uplifting or glamorous, so they often are overlooked. Consultants who don’t spend a lot amount of time in the ICU may be uncomfortable with them. This makes it even more important that we have a […]
PulmCrit- Controlled aquaresis: Management of hypervolemic or euvolemic hyponatremia with oral urea
I’ve been yearning to use oral urea for euvolemic hyponatremia for years (e.g. see a post from 2015 here). Urea has been used in Europe for decades, but until very recently it was unavailable in the United States. It has numerous advantages compared to the vaptans (which are extremely expensive and potentially dangerous). Recently, an […]
