Using national registry data from >400 intensive care units (ICUs), researchers examined outcomes of 49,656 adults (median age, 69) who suffered first cardiopulmonary arrests (CPAs) while in the ICU between 2000 and 2008. Overall rate of survival to hospital discharge was 15.9%.
Patients who received pressors before CPA were about half as likely to survive to discharge (9.3% vs. 21.2%) or to be discharged home from the hospital (3.9% vs. 8.5%) as were patients who did not require pressors before CPA. The best outcomes were among patients with CPA owing to ventricular tachycardia or ventricular fibrillation who did not require pressors prior to CPA (40.7% survived to discharge; 17.1% were discharged home with good neurological function).
