Summary

Intraoperative cardiac arrests occurred in 55 of 10,000 operations. Emergency surgery and higher American Society of Anesthesiologists (ASA) status were linked to increased risk and poorer prognosis.

Area of Science:

  • Anesthesiology
  • Critical Care Medicine
  • Surgical Outcomes

Background:

  • Intraoperative cardiac arrest poses a significant risk to patient safety during surgery.
  • Understanding the incidence and associated factors is crucial for improving patient outcomes in operating suites.

Purpose of the Study:

  • To determine the incidence of intraoperative cardiac arrests at University College Hospital (UCH), Ibadan.
  • To identify factors associated with intraoperative cardiac arrest.
  • To explore factors influencing prognosis following intraoperative cardiac arrest.

Main Methods:

  • Retrospective, descriptive, and cross-sectional study design.
  • Data collected from theatre records, intensive care records, case notes, and pathology reports.
  • Analysis of 6,356 operations performed between January 1994 and December 1998.

Main Results:

  • An overall incidence of 55 cardiac arrests per 10,000 operations was observed.
  • Emergency operations (68.6%) and higher American Society of Anesthesiologists (ASA) status (III-V: 71.4%) were associated with cardiac arrest.
  • Full recovery rates were higher in elective cases (41.7%) compared to emergency cases (17.1%).

Conclusions:

  • Emergency surgery and ASA status are significant risk factors for intraoperative cardiac arrest.
  • Prognosis appears to be influenced by the nature of the operation (elective vs. emergency) and patient's pre-operative health status.
  • Findings highlight the need for vigilant monitoring and risk stratification in surgical patients, particularly those undergoing emergency procedures or with compromised health.
