Validation of direct intraabdominal pressure measurement using a continuous indwelling compartment pressure monitor.
BACKGROUND
According to recommendations, intraabdominal pressure should be monitored every 8 hours for patients at high risk of abdominal compartment syndrome. Continuous intraabdominal pressure monitoring may be valuable for these patients.


METHODS
For 15 patients undergoing laparoscopic surgery, a pressure monitor was introduced after formation of pneumoperitoneum. During the procedure, the laparoscopic insufflator pressure was varied. The pressure monitor values and the time to equilibrium were recorded.


RESULTS
Altogether, 152 pressure recordings were taken for the patients studied. The measurements from the insufflator and pressure monitor were compared using a Bland-Altman plot. The mean difference between the techniques was 0.04 +/- 3.8, and 95% of the points from the pressure monitor were within two standard deviations of the mean difference. Pressure changes were essentially "real time."


CONCLUSIONS
The intracompartmental pressure monitor provides accurate, rapid, and direct measurement of intraabdominal pressure, and may be a useful tool for continuous intraabdominal pressure measurement among patients at risk of abdominal compartment syndrome.
