目的：探讨呼气末正压通气（positive end-expiratory pressure，PEEP）不同压力对腹内压（intra-abdominal pressure，IAP）测量的影响。方法采取前瞻性队列研究。2010年8月-2013年8月入住我院重症监护病房的患者15例，取仰卧位，比较不同呼气末正压通气时测得的两组IAP值（呼气末正压分别为5 cmH2O和10 cmH2O）。采用配对t检验和Bland-Altman统计方法进行统计学分析。结果 IAP5值范围11～20.6 mmHg，平均（15.56±2.46）mmHg，IAP10值范围11～20.6 mmHg，平均（15.68±2.36）mmHg，差异无统计学意义（P=0.18）。结论仰卧位机械通气患者，在PEEP值小于10 cmH2O条件下，PEEP改变对IAP测量无明显影响。

Objective To examine the effect of positive end-expiratory pressure (PEEP) on the measurement of intra-abdominal pressure (IAP). Method Prospective cohort study was taken. Fifteen mechanically ventilated patients were studied from August 2010 to August 2013 in the intensive care unit. All patients were studied with sequentially increasing PEEP (5 cm H2O and 10 cmH2O) during a PEEP-trial. The IAP measurements obtained at different PEEP values were compared using a paired t-test and Bland-Altman statistics. Results There’s no statistically significant difference between IAP5[(15.56±2.46)mmHg] and IAP10[(15.68±2.36)mmHg](P=0.18). Conclusions In the supine position, when the PEEP value was less than 10 cmH2O, PEEP changes did not obviously effect on IAP measurement.
