不同体位对经膀胱内途径间接测定腹内压影响的研究

The influence of the patients＇different body positions on indirectly measuring the intra - abdominal pressure through bladder pressure

目的观察不同体位下经膀胱内途径间接测定腹内压的影响。方法对2006—2008年本院ICU收治的48例腹内压增高的患者按IAP高低分级经膀胱间接测定腹内压。其中IAPI级10例，IAPII级18例，IAPIII级12例，IAPIV级8例。分别取平卧位、15°、30°、45°四种不同体位下观察腹内压的变化情况。结果体位改变使患者腹内压数值发生改变，特别是45°体位时更为明显。结论对于经膀胱内途径间接测定腹内压时要采取平卧位才使监测数据更具准确性和客观性。

Objective To investigate different patients＇body positions influenced the intra- abdominal pressure. Methods There were 48 patients with intra - abdominal hypertension （IAH） from years of 2006 to 2008 in ICU. According to the value , the intra - abdominal pressures were ranked them four grades as four groups also： Ⅰ （10 cases） , Ⅱ （18 cases） , Ⅲ （12 cases） , Ⅳ （8 cases）. Every pafientg intra- abdominal pressures were measured under 4 different body positions： prostration, elevations of 0° , 15°, 30°, 45° corresponding respective group. Results The value of intra - abdominal pressures were changed as posifion＇s variance, especially under elevations of 45°. Conclusions In order to get precise and objective data of intra - abdominal pressure, patients＇position should be prostration.
