Outcomes in patients requiring intensive care unit (ICU) admission after emergency laparotomy: A retrospective study

Purpose Outcomes after emergency laparotomy (EL) are poor. These patients are often admitted to an intensive care unit (ICU). This study explored outcomes in patients who were admitted to an ICU within 48 h after EL. Materials and Methods This retrospective single-center registry study included all patients over 16 years of age that underwent an EL and were admitted to an ICU within 48 h after surgery in Oulu University Hospital, Finland between January 2005 and May 2015. Survival was followed until the end of 2019. Results We included 525 patients. Hospital mortality was 13.3%, 30-day mortality was 17.3%, 90-day mortality was 24.2%, 1-year mortality was 33.0%, and 5-year mortality was 59.4%. Survivors were younger (57 [45-70] years) than the non-survivors (73 [62-80] years; p < .001). According to the Cox regression model, death during the follow-up was associated with age, APACHE II-score, lower postoperative CRP levels and platelet count of the first postoperative day, and the admission from the post-anesthesia care unit (PACU) to the ICU instead of direct ICU admission. Conclusion Age, high APACHE II-score, low CRP and platelet count, and admission from the PACU to the ICU associated with mortality after EL in patients admitted to an ICU within 48 h after EL.
