Risk factors of emergency reoperations

BACKGROUND: Emergency reoperation is considered to be a quality indicator in surgery. We analyzed the risk factors for emergency reoperations. METHODS: Patients who underwent emergency operations from January 1, 2017, to December 31, 2017, at our hospital were reviewed in this retrospective study. Multivariate logistic regression was performed for the perioperative risk factors for emergency reoperation. RESULTS: A total of 1,481 patients underwent emergency operations during the study period. Among them, 79 patients received emergency reoperations. The variables related to emergency reoperation included surgeries involving intracranial and intraoral lesions, highest mean arterial pressure ≥ 110 mmHg, highest heart rate ≥ 100 beats/min, anemia, duration of operation >120 min, and arrival from the intensive care unit (ICU). CONCLUSIONS: The type of surgery, hemodynamics, hemoglobin values, the duration of surgery, and arrival from ICU were associated with emergency reoperations.
