Post-anesthesia care unit hypotension in low-risk patients recovering from non-cardiac surgery: a prospective observational study
Authors' conclusion
In low-risk patients recovering from non-cardiac surgery, the incidence of PACU hypotension was very low and the few episodes of PACU hypotension were short and of modest severity.
Study context
- Population
- Low-risk patients recovering from non-cardiac surgery in the post-anesthesia care units (PACU)
- Participants
- 100 patients
- Outcome
- Incidence, duration and severity of PACU hypotension (MAP < 65 mmHg)
Methodological detailsblinded continuous non-invasive arterial pressure monitoring (finger-cuff)
- Blinded continuous non-invasive arterial pressure monitoring (finger-cuff)
