Perioperative mortality related to anesthesia within 48 h and up to 30 days following surgery: A retrospective cohort study of 11,562 anesthetic procedures

The study confirms that postoperative mortality in which anesthesia was involved occurred earlier in the perioperative period. In addition, it was revealed that this involvement of anesthesia as a morbidity contributor shows higher frequency when considering the anesthesiologist perioperative role, and when assessing the mortality in the long term (30 days).
