体位对腹腔内压力影响临床观察

The clinical experiment of effect of posture on intra - abdominal pressure

目的观察不同体位对腹腔内压力的影响。方法根据68例腹部疾病患者平卧位时测量的腹腔内压力分为低压组（〈20mmHg）和高压组（≥20mmHg），用间接膀胱测压法测量患者在平卧位，抬高床头15°、30°和45°时4种体位的腹腔内压力。结果与平卧位比较，抬高床头15°时腹腔内压力无明显变化，抬高床头30。和45。时腹腔内压力增大（P〈0．05），高压组尤甚。结论抬高床头可增大腹腔内压力，对腹压高者尤为显著。

Objective To explore the effect of the different body position on intra - abdominal pressure （IAP）. Methods 68 patients with abdominal disease were divided into low pressure group （IAP 〈 20 mmHg） and high pres- sure group （IAP ≥20 mmHg） based on the IAP measured by the indirect bladder manometry in the supine position. The IAP was monitored in the supine position and when the head of bed was elevated 15°, 30° and 45°respectively. Results Compared with the score of IAP in the supine position, the score of IAP had no significant change when the head of bed was elevated 15°. However, AIAP was significantly increased when the head of bed was elevated 30° and 45° （ P 〈 0.05 ）, especially occurred in high pressure group. Conclusions IAP increases in patients when the head the bed is el- evated, especially patients with the higher IAP.
