【 摘 要 】

Priapism following spinal anaesthesia for urological procedures is a rare occurrence .It is a troublesome complication which may pose a challenge to the urologist in proceeding with the surgery or even may result in cancellation of the elective procedure. We present a case of occurrence of priapism in a hypertensive patient posted for transurethral resection of prostrate following subarachnoid block and the way we managed it. Studies in the past two decades have mentioned various techniques of treating this intraoperative complication, e.g. the intracorporeal injection of vasopressors, subcutaneous or intravenous terbutaline and intravenous glycopyrrolate. In our case, we successfully dealt this complication with intravenous glycopyrrolate.
