To compare measurements of intraabdominal pressure (IAP) via a naso-gastric tube with the previously validated technique of IAP measurement via a urinary bladder catheter. To examine an association between elevated IAP and oliguric acute renal failure.
Simultaneous paired measurements of gastric and urinary bladder pressures in supine patients.
The general intensive care units of two London hospitals.
141 Paired measurements of intragastric and urinary bladder pressures were obtained in 26 general intensive care patients.
With the patient lying supine, 50 ml of sterile water were instilled via manometer tubing into the stomach and bladder following drainage of each viscera. The mid-axillary line was used as the zero reference, and cavity pressures noted in centimeters of water (cmH2O) at end expiration. The results were compared using the technique of Bland and Altman.
Gastric pressure may be approximately 2.5 cmH2O above or below urinary bladder pressure. Manometric measurement of the gastric pressure via a naso-gastric tube provides a simple, reliable, non-invasive technique of IAP measurement. IAP should be regularly monitored in patients with abdominal distension at risk of acute renal failure.
比较通过鼻胃管测量腹腔内压力（IAP）与先前经验证的通过膀胱导管测量IAP的技术。研究IAP升高与少尿型急性肾衰竭之间的关联。
对仰卧位患者同时进行胃内和膀胱压力的配对测量。
伦敦两家医院的综合重症监护病房。
对26名综合重症监护患者进行了141次胃内和膀胱压力的配对测量。
患者仰卧位时，在排空每个脏器后，通过压力计管道向胃和膀胱内注入50 ml无菌水。以腋中线作为零参考点，在呼气末记录以厘米水柱（cmH2O）为单位的腔压力。使用Bland和Altman技术比较结果。
胃内压力可能比膀胱压力高约2.5 cmH2O或低约2.5 cmH2O。通过鼻胃管进行胃内压力的压力测量提供了一种简单、可靠、非侵入性的IAP测量技术。对于有急性肾衰竭风险的腹胀患者，应定期监测IAP。
