Continuous wireless pre‐ and postoperative vital sign monitoring reveal new, severe desaturations after vascular surgery
Authors' conclusion
A longer duration of severe desaturation was found on the first postoperative day in the ward compared to preoperatively, whereas moderate desaturations were reflected in postoperative desaturations.
Study context
- Population
- Arterial vascular patients undergoing major vascular surgery
- Participants
- 40 patients
- Exposure
- Preoperative vs postoperative vital signs
- Outcome
- Cumulative duration of SpO2 < 85% / 24 h
Methodological detailscontinuous wireless monitoring, Median monitoring time 21 h preoperatively and 42 h postoperatively
- Continuous wireless monitoring
- Median monitoring time 21 h preoperatively and 42 h postoperatively
Main finding
As reported in the abstract
Cumulative duration of SpO2 < 85%
Day 0 ward vs Preoperative: P = 0.09 · Day 1 ward vs Preoperative: P = 0.61
Observational data: associations, not effects.
