Catheter-related bladder discomfort(CRBD) is a frequent complication after indwelling catheter under general anesthesia. The incidence of CRBD in patients undergoing Transurethral resection is as high as 66.7-91.2%.CRBD may lead some poor prognosis including postoperative restlessness, bleeding, and circulatory instability.therefore，how to reduce the incidence of CRBD is one of the urgent problems to be solved in clinic.~Oxycodone Hydrochloride is a strong opioid receptor agonist used in clinic at present. It has certain advantages in the regulation of visceral pain and can produce analgesic effect without causing restlessness, gastrointestinal motility inhibition and respiratory inhibition through stimulating the μ and κ opioid receptor simultaneously. However, the effect of Oxycodone Hydrochloride on catheter-related bladder discomfort in patients undergoing transurethral resection of bladder tumor after general anesthesia is still unknown. The purpose of this study is to explore whether Oxycodone Hydrochloride via intravenous injection could reduce the incidence of CRBD in patients undergoing transurethral resection of bladder tumor after general anesthesia and could not increase other complications during the recovery period of general anesthesiathe.
The purpose of this study is to investigate the effect of Oxycodone Hydrochloride on catheter-related bladder discomfort in patients undergoing transurethral resection of bladder tumor after general anesthesia.
