摘要
目的观察体位对经膀胱内途径间接测定腹内压的影响。方法按腹腔内压力(intra-abdominal pressure,IAP)分级对2011年5月—2012年1月ICU收治的12例腹内压增高患者在平卧位(0°)采用经膀胱内途径间接测定IAP,共72例次,分别取15°、30°体位下观察IAP的变化情况。结果不同体位下IAP值比较差异有统计学意义,15°、30°体位下IAP值与平卧位IAP值相比较,差异有统计学意义(P<0.01),15°、30°体位下IAP值较0°IAP值分别增加(1.94±0.49)、(5.02±0.88)mmHg(1 mmHg=0.133 kPa),抬高体位和IAP增加呈正相关(r=0.87,P<0.01)。结论抬高体位使患者IAP增加,仰卧位测量的IAP可能低估了床头抬高的患者的真实IAP,应引起重视。
Objective To observe the influence of patients＇ body positions on indirect measurement of intra-abdominal pressure （IAP） via the bladder. Methods From May 2011 to January 2012, indirect measurement of intra-abdominal pressure of 12 patients in ICU was performed 72 times via the bladder. IAP changes were recorded in supine position, 15° and 30° head-up tilt positions respectively. Results Compared with IAP values in supine position, IAP values in 15°, 30°head-up tilt positions increased （1.94±0.49） and （5.02±0.88） mmHg respectively, which were of significant difference （P〈0.01）. Increased IAP values were positively correlated with bed elevated positions （r=0.87, P〈0.01）. Conclusion The elevation of body position results in the increasing of lAP values. The measurement of lAP values in supine position may underestimate the true IAP values of patients in bed elevated.
