Influence of Anaesthesia Management Parameters on the Occurrence of Severe Morbidity and Death

Description

Abstract (English)

Abstract
Background: There are few quantitative assessments of how anaesthesia management affects perioperative
morbidity and mortality. The authors conducted a study to determine risk variables for anaesthetic care about
severe morbidity and mortality within 24 hours of surgery.
Methods: In a case-control study conducted in 2021–2022, anaesthetized patients were evaluated. Within 24
hours of being put under anaesthesia, some patients in the cases passed away or went into a coma; in contrast, the
controls 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. Some
significant anaesthetic management factors associated with decreased risk were using a checklist and protocol to
check equipment (odds ratio: 0.64), recording equipment checks (odds ratio: 0.61), having a direct
anaesthesiologist available (odds ratio: 0.46), having the same anaesthesiologist present during anaesthesia (odds
ratio: 0.44); having a full-time working anaesthetic nurse (odds ratio: 0.41); having two people present at
emergence (odds ratio: 0.69); and reversing anaesthesia (odds Postoperative pain medicine also carried a lower
risk profile, mainly when administered intramuscularly or epidurally as opposed to intravenously.
Conclusions: Preoperative unconsciousness and death are associated, making postoperative mortality a severe
problem. Anaesthetic management factors that impact this association include using medications during and after
therapy, the type of anaesthetic care given during and after surgery, and the presence of anaesthesiologists
throughout the procedure
