AbstractBackground: There are few quantitative assessments of how anaesthesia management affects perioperativemorbidity and mortality. The authors conducted a study to determine risk variables for anaesthetic care aboutsevere morbidity and mortality within 24 hours of surgery.Methods: In a case-control study conducted in 2021–2022, anaesthetized patients were evaluated. Within 24hours of being put under anaesthesia, some patients in the cases passed away or went into a coma; in contrast, thecontrols did not experience any of these outcomes. The Anaesthesia and Recovery Form was used to gather data,and confounder-corrected odds ratios were the result.Results: The cohort comprised 869,483 patients; 705 cases and 711 controls were studied. The frequency of 24-hour postoperative death was 8.8 per 10,000 anaesthetics, while the rate of unconsciousness was 0.5. Somesignificant anaesthetic management factors associated with decreased risk were using a checklist and protocol tocheck equipment (odds ratio: 0.64), recording equipment checks (odds ratio: 0.61), having a directanaesthesiologist available (odds ratio: 0.46), having the same anaesthesiologist present during anaesthesia (oddsratio: 0.44); having a full-time working anaesthetic nurse (odds ratio: 0.41); having two people present atemergence (odds ratio: 0.69); and reversing anaesthesia (odds Postoperative pain medicine also carried a lowerrisk profile, mainly when administered intramuscularly or epidurally as opposed to intravenously.Conclusions: Preoperative unconsciousness and death are associated, making postoperative mortality a severeproblem. Anaesthetic management factors that impact this association include using medications during and aftertherapy, the type of anaesthetic care given during and after surgery, and the presence of anaesthesiologiststhroughout the procedure
