Prognostic factors for mortality in patients postoperatively with acute occlusive abdomen
Keywords:

Introduction: Surgical etiology is a common reason for admission to the intensive care unit. Objective: To determine the behavior of prognostic factors for mortality in postoperative patients with acute abdominal occlusion admitted to the intensive care unit of Dr. Agostinho Neto General Hospital between 2022 and 2023. Method: A descriptive, retrospective, and cross-sectional study was conducted among patients discharged from the intensive care unit (n = 56) with a postoperative diagnosis of intestinal occlusion. The discharge status, age, sex, comorbidity, complications, organ dysfunction, and nutritional status were analyzed. The odds ratio (OR) was calculated for each variable studied. Results: All selected variables were independent risk factors for mortality in postoperative patients with intestinal obstruction, but those with a higher probability of death were complications with ARDS (OR: 7.1; 95% CI: 5.1–8.4) and multiorgan failure (OR: 6.3; 95% CI: 3.9–8.6). An APACHE II score greater than 20 points increased the likelihood of death sevenfold (OR: 6.7; 95% CI: 3.9–8.7); being older than 60 years increased this likelihood fivefold (OR: 5.1; 95% CI: 2.1–8.4). Conclusions: Age greater than 60 years, complications with ARDS and multiorgan failure, and an APCHE II score greater than 20 points were causal factors explaining mortality.
