PulmCrit- CITRIS-ALI: Can a secondary endpoint stage a coup d’état?
background on IV vitamin C We live in divided times. Paul Marik’s study on using vitamin C in sepsis was perhaps the most polarizing publication in recent memory (aside from perhaps the Mueller report). It was lauded by some, yet derided just as strongly by others. Unfortunately, the kerfuffle surrounding this study overshadowed the larger […]
PulmCrit- Triple therapy for influenza with naproxen, clarithromycin, and oseltamavir?
Flu seasons is upon us again. A recent paper in CHEST provides some tantalizing evidence about possible treatment. Will this pan out, or is it just another fairy tale?
PulmCrit- SUP-ICU: Is pantoprazole the elixir of life? Should it be?
SUP-ICU is a massive, modern RCT of stress ulcer prophylaxis (SUP) in the ICU. With 3298 patients, it is larger than many meta-analyses of SUP. Its primary mortality endpoint is deeply flawed. However, the study still provides a wealth of information about SUP in the ICU.
PulmCrit Wee – Urine toxicology screens should be removed from brain death guidelines
Prior to declaring a patient brain dead, confounding factors which could falsely cause the patient to appear dead must be eliminated. One important confounder is intoxication. Failure to recognize that a patient is intoxicated could lead to an incorrect diagnosis of brain death that in turn can lead to withdrawal of life support – thereby […]

PulmCrit- Epinephrine challenge in sepsis: An empiric approach to catecholamines
A 55-year-old woman was admitted with toxic shock syndrome. Her norepinephrine requirement was labile, fluctuating between 15 mcg/min and 30 mcg/min. Bedside echocardiogram showed a dilated inferior vena cava without respiratory variability, and a normal ejection fraction. On examination her extremities were cool and her urine output was marginal.

PulmCrit- Six myths promoted by the new surviving sepsis guidelines
Early Goal-Directed Therapy: A house collapsing in slow motion The original foundation of the Surviving Sepsis Campaign was the Rivers trial on early goal-directed therapy. This is basically the NINDS trial of the critical care world: a study with ~300 patients showing implausibly positive results, published in NEJM, and rapidly brainwashing an entire discipline. The […]
