[Activated protein C treatment: experience about 23 patients in the operative period]

Abstract

Objective: To evaluate the use of activated C protein (ACP) in a Surgical Intensive Care Unit.

Study design: A prospective observational study.

Patients and methods: All patients receiving ACP during 20 months in the operative period.

Results: Twenty-three patients were treated by ACP. The origin of sepsis was peritonitis (n = 14), infected pancreatitis (n = 3), mediastinitis (n = 2), one urologic sepsis, one facial cellulitis, one catheter related infection, and one postoperative pneumonia. In two cases, the peritonitis was associated with a pleuretic infection, and in two other cases with parietal cellulites. Mean age was 69+/-13 years. Severities evaluated by SAPS II, LODS were 59+/-13 and 7+/-3, respectively. Mean number organ dysfunction was 3.3+/-1.0. Septic shock was present in 91% with concomitant use of catecholamines for a mean period of 87+/-64 hours. Bacteraemia was present in 43% of the patients. A treatment with hydrocortisone was associated in 52% of the patients. The ICU and hospital lengths of stay were 15+/-16 days, and 34+/-38 days, respectively. Mortality at day 28 was 35%. Two significant bleeding were observed, one requiring red blood cell transfusion and the other one a surgical control of the bleeding associated with red blood cell transfusion.

Conclusion: With global management of severe sepsis, including the use of activated C Protein, this prospective observational study showed a 30% reduction of the predicted mortality by SAPS II scoring without significant increase of bleeding episodes in a surgical context.
