膀胱内压

予以腹壁减张或开腹减压术者，监测其术后24h尿量、膀胱内压、中心静脉压、动脉收缩压、动脉血氧分压（PaO2），并与术前比较。

Bladder pressure , central venous pressure , systolic blood pressure and arterial blood oxygen partial pressure ( PaO2 ) were measured and compared before and after operation .

多数患者术前24h尿量偏少，膀胱内压、中心静脉压、动脉收缩压和PaO2表现异常，手术患者术后各项指标较术前明显好转（P0.01）。

Most of patients were oliguric , with abnormal bladder pressure , central venous pressure , and systolic blood pressure 24 hours before operation . But these parameters were significantly improved after operation ( P0.01 ) .

训练前后记录安全容量、基础膀胱内压、最高膀胱内压、自排尿量、残余尿量、排尿时程等数据。

The safe capacity , basal IP , maximum IP , urinary output , residual urine volume and time course of urination were recorded before and after training .

预防和治疗肾积水的首要原则是保持膀胱低内压（储尿期<40cmH2O、排尿期<60cmH2O）。

The paramount principle of prevention and treatment of hydronephrosis is keeping low vesical pressure ( storage pressure < 40 cmH_2O , voiding pressure < 60 cmH_2O ) .

方法：采用麻醉大鼠左侧颈总动脉插管记录血压，经右侧颈总动脉左心室插管记录左心室内压，以及膀胱顶部插管记录膀胱内压。

Method : In anesthetized rats , carotid blood pressure , left ventricular pressure and the vesical pressure were recorded .

在排尿期，膀胱颈和后尿道肌肉松弛，逼尿肌持续的收缩，在膀胱内压作用下，尿液排出。

During the micturition phase , the bladder neck and urethral muscles relax , and the detrusor contracts and expel urine without major resistance .

主要观察指标：记录膀胱神经丛动作电位和膀胱平滑肌复合肌肉动作电位变化，同时通过膀胱内插入测压管并经压力换能器记录膀胱内压的变化。

MAIN OUTCOME MEASURES : To record the change of action potential of cystic nerve plexus and compound muscle action potential of bladder smooth muscle , and insert the pressure monitor into bladder to record internal pressure of bladder by pressure transducer .
