İntraoperatif Anestezi İlişkili Mortalite: Bir Yükseköğretim Hastanesinde 10 Yıllık Bir Araştırma

Abstract

Purpose: This study aimed to determine anesthesia-related mortality and intraoperative mortality (IOM) incidences and the associated risk factors. Material and Methods: The operations between the years of 2010-2019 were retrospectively reviewed. It was found that 87 of 351,930 patients who were anesthetized in the last 10 years died. Each patient who died was recruited into one of the patient/condition-related, surgical-related, or anesthesia-related mortality groups. Patient characteristics were determined as age, gender, ASA PS score, and comorbidities. Surgical procedures were classified as minor/intermediate, major, and major complex. Anesthesia type was recorded. Operative time, the requirement for vasopressor and the invasive monitoring were determined. Results: The incidence of IOM and anesthesia-related mortality were 2.47 and 0.28 per 10,000 patients, respectively. The IOM group had a higher rate of out-of-hours work, surgical emergency, prolonged operative time, high comorbidity rate, high ASA PS score, major complex surgeries, use of VP, and invasive monitoring. Surgical emergency (p: 0.000), use of VP (p: 0.002), and invasive monitoring (p: 0.000) were independent determinants of IOM. Major complex surgeries (p: 0.007), surgical emergency (p: 0.000), use of VP (p: 0.002), and invasive monitoring (0.000) were potentially associated factors in anesthesia-related mortality. Conclusion: The incidence of IOM and anesthesia-related mortality were 2.47 and 0.28 per 10,000 patients, respectively. The fact that anesthesia-related mortality was associated with drug administration is important for the development of preventive measures. Primary prevention may play a key role in reducing the high fatality. These results indicate the need for improving medical perioperative practices in high-risk and emergency patients
