Purpose: To determine the incidence of postintubation hypotension (PIH) and associated outcomes in critically ill patients requiring endotracheal intubation.
Materials and methods: Medical records were reviewed for 479 consecutive critically ill adult patients who required intubation by an intensive care unit (ICU) service at 1 of 4 academic tertiary care hospitals. The primary outcome measure was the incidence of PIH. Secondary outcome measures included mortality, ICU length of stay, requirement for renal replacement therapy, and a composite end point consisting of overall mortality, ICU length of stay greater than 14 days, duration of mechanical ventilation longer than 7 days, and renal replacement therapy requirement.
Results: Overall, the incidence of PIH among ICU patients requiring intubation was 46% (218/479 patients). On univariate analysis, patients who developed PIH had increased ICU mortality (37% PIH vs 28% no PIH, P = .049) and overall mortality (39% PIH vs 30% no PIH, P = .045). After adjusting for important risk factors, development of PIH was associated with the composite end point of major morbidity and mortality (odds ratio, 2.00; 95% confidence interval, 1.30-3.07; P = .0017).
Conclusions: The development of PIH is common in ICU patients requiring emergency airway control and is associated with poor patient outcomes.
