Incidence of intraoperative hypotension during non-cardiac surgery in community anesthesia practice: a retrospective observational analysis
Authors' conclusion
Intraoperative hypotension is common in community anesthesia practice, including among patients and settings typically considered "low risk."
Study context
- Population
- Adults having non-emergent, non-cardiac surgery under general, neuraxial or RA at 45 community facilities in the US, 2020–2021
- Participants
- 127,095 cases
- Outcome
- IOH (MAP < 65 mmHg for ≥15 min cumulatively)
Methodological detailsretrospective, descriptive, multicentre
- Retrospective
- Descriptive
- Multicentre
Main finding
As reported in the abstract
Cases with mean arterial pressure (MAP) < 65 mmHg for at least 15 min cumulatively
29%
Observational data: associations, not effects.
Further findings
Minutes of MAP < 65 mmHg
- Overall mean min < 65 mmHg
- 12.4 min
Intraoperative hypotension (IOH) by patient, procedure and facility characteristics
- IOH slightly more common in younger, female and American Society of Anesthesiologists (ASA) II (vs III or IV) patients; in longer procedures with higher anesthesia base units; and in ambulatory surgery centers
IOH across clinicians
- Incidence varied widely across individual clinicians in unadjusted and risk-adjusted analyses
