    Summary
    Objective: To investigate whether the compartment pressure of the rectus sheath (CPRS) reflects the intra-abdominal pressure (IAP) under various conditions of intra-abdominal hypertension (IAH). Design and setting: Prospective experimental study with in vivo pressure measurements at the Institute for Clinical and Experimental Surgery, University of Saarland. Animals: Sprague-Dawley rats. Interventions: Stepwise increase and decrease in IAP with continuous measurement of the correspondent CPRS. Measurements and results: Physiological IAP (2 mmHg) and CPRS (6 mmHg) showed astatistically significant difference. Stepwise elevation in IAP was associated with asimultaneous increase in CPRS. Accordingly, stepwise decompression of IAP resulted in astepwise decrease in CPRS. Under both conditions Bland-Altman analysis comparing IAP to correspondent CPRS showed avery good agreement for IAP at or above 12 mmHg. In addition, closure of the overlaying subcutaneous tissue and skin did not affect CPRS or its correlation with IAP. Conclusions: CPRS accurately reflects IAP for IAP of 12 mmHg or higher. Thus CPRS measurements may represent anovel approach for diagnosis and monitoring of IAH
