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.

Objective To investigate the clinical effect of hyaluric acid sodium injection and functional exercises on patients with comminuted fracture of tibia plateau after reposition. Methods 134 patients with comminuted fracture of tibia plateau after reposition were randomized into the observation group and the control group with 67 cases in each group. The observation group received 2ml of hyaluric acidsodium injection into the knee joint cavity with 1％ lidocaine once a week and 3 times totally. At the same time active and passive functional exercises were applied. The control group was only given routine nursing. The knee function was evaluated by Lysholm Scale 4 months after operation and the results were compared. Results The score of the observation group was higher than that of the control group(P＜0.01).Conclusion The hyaluric acid sodium injection and functional exercises could improve the healing of joint cartilage and contribute to the rehabilitation of joint function in patients with comminuted fracture of tibia plateau after reposition.
