Septic Shock Death Equal With High, Low BP Target
(HealthDay News) — For patients with septic shock undergoing resuscitation, 28- and 90-day mortality is not significantly different with high- or low-target arterial pressure. This research was published online March 18 in the New England Journal of Medicine to coincide with presentation at the International Symposium on Intensive Care and Emergency Medicine, held from March 18–21 in Brussels.
Pierre Asfar, MD, PhD, from the University Hospital of Angers in France, and colleagues randomized 776 patients with septic shock to undergo resuscitation with a high or low blood-pressure target. The mean arterial pressure of the high-target group was 80–85mm Hg, while that of the low-target group was 65–70mm Hg.
The researchers observed no significant between-group difference in mortality at 28 days (36.6% in the high-target group vs. 34.0% in the low-target group; hazard ratio in the high-target group, 1.07; P=0.57). No significant difference was seen in mortality at 90 days (43.8 vs. 42.3%, respectively; hazard ratio, 1.04; P=0.74). Compared with the low-target group, the incidence of newly diagnosed atrial fibrillation was higher in the high-target group.
"Targeting a mean arterial pressure of 80–85mm Hg, as compared with 65–70mm Hg, in patients with septic shock undergoing resuscitation did not result in significant differences in mortality at either 28 or 90 days," the authors write.
