To explore the value of dezocine in the prevention of urinary catheter related bladder discomfort (CRBD) after general anesthesia.

68 patients undergoing laparoscopic cholecystectomy under general anesthesia in our hospital from February 2014 to May 2016 were selected, all patients required indwelling catheter. All patients were divided into the observation group and the control group according to whether the prophylactic application of dezocine, patients of two groups were inserted urinary catheter after induction of general anesthesia. Twenty minutes before the end of the operation, the patients in the observation group were treated with intravenous injection of 0.1 mg/kg of dezocine, while the patients in the control group were treated with intravenous injection of 0.05 ml/kg of 0.9% sodium chloride. After the extubation, the occurrence and severity of CRBD were observed and analyzed.

The incidence and severity of CRBD in the observation group were significantly lower than those in the control group (P<0.05). Riker sedation-restlessness score of the observation group was significantly lower than that of the control group at different time points after the extubation (P<0.05).

For patients indwelling catheter under general anesthesia, intravenous injection of dezocine 20 minutes before the end of the operation can effectively reduce the risk of CRBD, has very positive significance in the reduction of pain and promoting the smooth recovery of patients, which is recommended to further promote in clinical.
