Associations between clinical interventions and transcutaneous blood gas values in postoperative patients
Authors' conclusion
Clinical interventions resulted in significant changes in transcutaneous oxygen and carbon dioxide.
Study context
- Population
- Adults after major surgery monitored with transcutaneous blood gas measurements for 2 h in the PACU190 analysed, 686 interventions
- Participants
- 200 adults
- Exposure
- TcPO2 and TcPCO2 5 min before vs 5 min after a clinical intervention
- Outcome
- Change in TcPO2 from 5 min before a clinical intervention vs 5 min after
Methodological detailsbefore-after comparison (paired t-test)
- Before-after comparison (paired t-test)
Main finding
As reported in the abstract
Change in TcPO2 during clinical interventions
Mean change in TcPO2 (mmHg), 95% CI −1.79-0.2, p = 0.015
0.99
Observational data: associations, not effects.
Further findings
Change in TcPCO2 during clinical interventions
- Mean change in TcPCO2 (mmHg), 95% CI 0.36-0.98, p < 0.001
- −0.67
