Usefulness of the Surgical Apgar Score to Predict the Occurrence of Major Complications in the Early Post-Operative Period of Major Surgeries: Experience of Two Second-Category Hospitals in Cameroon

引用

Open Journal of Anesthesiology 2024年第3期14卷 51-65页

作者： Charles Emmanuel Toussaint Binam Bikoi Francis Ateba Ndongo Serge Vivier Nga Nomo Édouard Léa Mekoui Ze Fidèle Binam Department of Anesthesia and Intensive Care University of Ebolowa Ebolowa Cameroon Yaounde Mother and Child Center Chantal Biya Foundation University of Garoua Garoua Cameroon Department of Anesthesia and Intensive Care Catholic University of Central Africa Yaounde Cameroon

Objective: The Surgical Apgar Score (SAS) is a tool for intraoperative stratification of the risk of serious complications in the early postoperative period. It varies from 0 to 10 points divided into three risk categories (0 to 4 high, 5 to 7 moderate, 8 to 10 low). The aim of the study was to evaluate its relevance in predicting the appearance of these complications. Material and methods: This descriptive and analytical study was carried out at the “Laquintinie” Hospital in Douala and at the Central Hospital in Yaounde, Cameroon. The main data were collected on a population of patients over 18 years old and recorded on a survey form. They consisted of variables of main interest and exposure variables. Univariate and multivariate statistical analysis using top-down logistic regression models made it possible to evaluate the association of each variable of main interest and each exposure variable. The association was significant at P Results: Of the 88 patients studied, the SAS was 3 hours. In multivariate, this link persisted only and strongly for the SAS OR (IC) 0.1 (0.1 - 0.2) and p = 000. Conclusion: The study found a specific and powerful link between the SAS score < 4 and the occurrence of complications in the early postoperative period, in favor of its relevance in predicting them.
