ABSTRACT
Objectives To investigate the effect of bladder function and behavior change training on urinary retention after epidural anesthesia and the method to decrease it. Methods 265 patients receiv-ing operation under epidural anesthesia were divided into two groups, the experimental group (132 cases) and the control group (133 cases). The experimental group was further divided into 3 groups: one to two days of training, 3 to 4 days of training and above 5 days of training preoperation. The experimental group carried out bladder function and behavior change training, but the control group never undertook any train-ing. After operation the data were analyzed. Results The incidence of urinary retention was significantly different between the experimental group and the control group (P<0.01);The time length of the training before operation aorrelated with incidence of urinary retention(P<0.05). Conclusions Bladder function and behavior change training contributed to decrease urinary retention after epidural anesthesia.The training time and incidence of urinary retention showed inverse proportion. This could decrease the opportunity of suffering from urethral catheterization and urinary tract infection.
