Intra-abdominal hypertension in cardiac surgery patients: a multicenter observational sub-study of the Accuryn registry
Authors' conclusion
During the first 48 h after cardiac surgery, IAH is common and persistent.
Study context
- Population
- Cardiac surgery patients monitored intraoperatively and 48 h postoperatively in the ICU, three large academic medical centres
- Participants
- 137 patients
- Primary endpoint
- Incidence of IAH (intra-abdominal hypertension) measured by high-frequency automated bladder pressure monitoring
- Follow-up
- 48 h postoperatively
Methodological detailsAccuryn registry, sub-analysis
- Accuryn registry
- Sub-analysis
