Abstract：Objective To investigate the effect of different intravesical infusion volumes on the measurement of intra-abdominal pressure ( IAP) in critically ill patients. Methods Prospective cohort study was taken. Forty critically ill patients with risk for intra-abdominal hypertension ( IAH) in the intensive care unit of Shijiazhuang Central Hospital were studied. Two infusion volumes were 25 ml and 50 ml respectively. Each patient was measured IAP at different volumes ( IAP25 ml and IAP50 ml ) in supine position for comparison. Results IAP25 ml was significantly lower than IAP50 ml [(8-21 (13. 95±3. 15) mmHg vs. 9-21(14. 90±3. 46) mmHg;P<0. 0001]. The average difference between the IAP25 ml and IAP50 ml was 0. 95 mmHg (95% CI 0. 60-1. 30;lower and upper limits of agreement: -1. 2 mmHg and 3. 1 mmHg, respectively). The Spearman rank correlation coefficient between IAP25 ml and IAP50 ml was 0. 924 (95%CI 0. 860-0. 959, P<0. 0001). Conclusion In the supine position, IAP50 ml is higher than IAP25 ml . The recommended clinical infusion volume is no more than 25 ml.
