Efficacy of Mannheim peritonitis index (Mpi) score in patients with perforation peritonitis

Abstract

Background: Despite aggressive surgical treatment and evolution of critical care, the prognosis of peritonitis and intraabdominal sepsis is not good especially when multiorgan failure develops. Aim: To study the efficacy of the Mannheim peritonitis index in predicting the outcome in a patient of peritonitis.Material and Methods: Analyzing the case files of all the operated cases of gastrointestinal perforations over the 5 years in the surgical department by open procedure. A total number of 200 cases were studied. The eight prognostic variables included in the Mannheim’s peritonitis index entered in a proforma and the MPI score of each patient was calculated.Results: Out of 200 patients 176 were discharged and 26 died. Mortality found in this study was 13%. Patients with MPI score >29 had max mortality (61.5%) and MPI between 21-29 scores had 20.9% mortality. Least mortality recorded in MPI score < 21(0.8%).Conclusion: MPI score is an excellent prognostic index for peritonitis with high accuracy in individual prognosis and that it is cheap, cost-effective, easily measurable, and reproducible.
