AbstractRight ventricular ejection fraction (RVEF) was measured by the thermodilution technique in a series of 127 consecutive critically ill patients monitored with a modified pulmonary artery (PA) catheter equipped with a fast response thermistor. Thermodilution RVEF was significantly lower in septic shock (23.8 +/- 8.2%, 93 measurements) than in sepsis without shock (30.3 +/- 10.1%, 118 measurements) or in the absence of sepsis or cardiopulmonary impairment (32.5 +/- 7.1%, 62 measurements). Both myocardial depression and pulmonary hypertension could account for this impairment of RV function. RVEF decreased from 35.1 +/- 9.8 to 24.2 +/- 10.4% (P less than 0.01) during development of septic shock and increased from 25.0 +/- 7.6 to 29.8 +/- 8.5% (P less than 0.05) during recovery (14 patients). Initial RVEF in septic shock was 27.8 +/- 8.6% in 11 patients who survived but only 20.9 +/- 6.7% (P less than 0.02) in the 23 patients who eventually died. Thus, RV dysfunction is common during septic shock, is directly related to its severity, and can easily be recognized in patients monitored with a PA catheter.
