Objective:
To compare intra-abdominal pressure (IAP) measurements obtained from an intragastric Compliance catheter with the pressure measured directly in the abdominal cavity.
Design And Setting:
Prospective cohort study in an operating room of the Ghent University Hospital
Patients:
Seven patients undergoing elective laparoscopic cholecystectomy.
Interventions:
IAP was obtained from both an intragastric catheter and directly from the peritoneal cavity at 1-minute intervals in patients undergoing elective cholecystectomy and compared using Bland-Altman analysis.
Measurements And Results:
In 156 paired measurements obtained from 7 patients the mean difference between IAPgastric and IAPref was 0.12+/-0.70 mmHg (95% CI 0.01-0.23).
Conclusions:
IAP measured using an intragastric Compliance catheter reliably reflects the reference IAP in patients undergoing laparoscopic cholecystectomy.
