ABSTRACT

Objective: Evaluating the usefulness of lactate as a diagnostic test for complications in critically-ill patients undergoing abdominal surgery. Material and methods: A prospective study was carried out in 198 patients randomly selected, admitted to Hospital «Guillermo Luis Fernández-Hernández Baquero”, Moa, Holguín, Cuba, from March, 2003, through February, 2004, to assess the usefulness of lactate values on admission for the diagnosis of intraabdominal septic complications in critically-ill patients undergoing abdominal surgery, and as a prognostic tool in these patients. Patients undergoing open abdominal surgical procedures at the first surgical stage were excluded from the study, as well as patients known to be diabetic and those in whom lactate was not measured on arrival. Participating patients were divided into two groups: Group I, with documented postoperative peritonitis, and Group II, with no postoperative peritonitis. In order to define the severity of disease in each study group, the APACHE II score was estimated on admission, and lactate levels were measured in a 2-ml sample of arterial blood. Results: Significant differences in lactate levels were seen among patients who ultimately died and survivors (p ‹ 0.01). Septic intraabdominal complications occurred in 16.75%, whereas mortality was 31.81%. Conclusions: Lactate measurements are a useful prognostic test in critically-ill patients undergoing abdominal surgery.
