This research aims to accurately determine the death rate associated with anesthesia and identify underlying causes related to its application.
Studied 599548 patients receiving anesthesia across 10 hospitals.
Analyzed death occurrences, focusing on anesthesia technique and agent.
Examined time trends in anesthesia usage over a 5-year period.
Total deaths in the study group were 7977, with an overall anesthesia death rate of 1:1560.
Higher mortality observed among men, with mortality statistics for potentially fatal conditions noted.
Use of intravenous anesthesia doubled, while inhalation anesthesia remained the primary technique.
