Shock Index Predicts Hypotension in Patients Induced with Ketamine
Daniel J. Pallin, MD, MPH
An observational study confirms that ketamine can cause hypotension in catecholamine-depleted patients.
Ketamine causes catecholamine release, but when used for rapid sequence intubation (RSI), it generally does not have hemodynamically consequential effects. In a prospective observational study, investigators in Australia evaluated the hemodynamic effects of ketamine in... Read more..

Treatment with dexmedetomidine for as long as 1 week shortened delirium duration and mechanical ventilation time by nearly 1 day.
Dexmedetomidine is a sedating α-2 agonist that doesn't impair respiratory drive. In this multicenter study, investigators randomized 74 intensive care unit (ICU) patients with agitated delirium to receive either... Read more..
