Area of Science:

  • Anesthesiology
  • Medical Device Safety

Background:

  • Updated guidelines for pre-operative anesthetic machine checks were published in March 1997 by the Association of Anaesthetists of Great Britain and Ireland.
  • Routine implementation of these guidelines is essential for ensuring anesthetic equipment functionality and patient safety.

Purpose of the Study:

  • To evaluate the adherence to the revised Association guidelines for pre-operative anesthetic machine checks.
  • To analyze the time required for these checks and identify common faults in anesthetic machines.

Main Methods:

  • A checklist based on the 1997 Association guidelines was used for routine pre-operative checks over six weeks.
  • 132 completed checklists were analyzed for time taken and machine faults.
  • Data on specific faults, including cylinder presence and component functionality, were recorded.

Main Results:

  • The mean time for a single check was 6.8 minutes; two consecutive checks averaged 12.7 minutes.
  • Carbon dioxide cylinders were incorrectly present on 75% of machines, violating guidelines.
  • Faults were identified in 30.3% of checks, with oxygen analyzers being the most frequent issue (15 checks).

Conclusions:

  • Significant deviations from Association guidelines were observed during routine pre-operative anesthetic machine checks.
  • Common faults, particularly with oxygen analyzers and cylinder management, highlight areas needing improvement.
  • Regular auditing and adherence to updated guidelines are necessary to enhance anesthetic equipment safety.
