【摘要】 目的　探讨正常腹内压的影响因素 ,建立腹内压回归方程。方法　应用膀胱测压法测定 10 6例住院患者的腹内压 ,并对年龄、性别、身高、体重、体质指数、既往和近期腹部手术史、住院原因、合并症情况及数量等 14项因子与腹内压的关系进行分析。结果　住院患者平均腹内压为 5 .5mmHg( 1mmHg =0 .133kPa) ,范围为 0 .4～12 .8mmHg。各级体质指数相应的腹内压差异有显著性意义 (F =5 .5 5 0 ,P<0 .0 1)。男性腹内压比女性高 2 .0mmHg ,差异有显著性意义 (t=3.12 2 ,P<0 .0 1)。其他 12种因素对腹内压无明显影响 (P>0 .0 5 )。结论　正常腹内压可能受性别和体质指数影响 ,存在明显的个体差异更多还原

【Abstract】 Objective To investigate the influent factors on normal intraabdominal pressure (IAP) and establish the IAP regressive equation. Methods The IAPs of 106 hospitalized patients were determined through monitoring the bladder pressures. The relationship between IAP and 14 factors including age, gender, height, weight, body mass index (BMI), previous and recent abdominal surgical history, reasons for admission,complications and their quantities were analyzed,respectively Results The mean IAP of the hospitalized patients was 5.5 mm Hg with a range from 0.4 mm Hg to 12.8 mm Hg. The difference among IAPs of different grades of BMIs had statistical significance ( F =5.550, P <0.01). The male IAPs were 2.0 mm Hg higher than the female IAPs,which had statistical significance ( t =3.122, P <0.01). The other 12 factors had no significant effects on IAP ( P >0.05). Conclusion Normal IAP is possibly influenced by gender and BMI,and it is individually different.更多还原
