Abstract

Objective

Because recombinant human activated protein C (rhAPC) reduces NO production during sepsis, it could improve the vascular tone. We tested whether rhAPC reduces the dose of norepinephrine required to maintain mean arterial pressure (MAP) in septic shock patients.

Design and setting

Retrospective study in intensive care unit of two university hospitals.

Patients

Twenty-two septic shock patients with at least two organ failures were retrospectively investigated for MAP and the required dose of norepinephrine before and 24 h after rhAPC administration. A control group of 22 septic shock patients with at least two organ failures who did not receive rhAPC was matched on age, SAPS II, MAP, and norepinephrine dose at the time of the theoretical start of rhAPC.

Measurements and results

The MAP remained stable and similar in the two groups (86±16 vs. 89±9 mmHg at 24 h). The required dose of norepinephrine increased in the control group (+38%, from −41% to +38%) but decreased in the treated group (−33%, from −74% to +11%).

Conclusions

rhAPC rapidly improved the vascular tone in septic shock patients as assessed by a decrease in the norepinephrine dose required to maintain arterial pressure.
