Local anesthesia during transrectal prostate biopsy

To determine the effectiveness of the longer acting agent bupivacaine for periprostatic anesthesia during transrectal ultrasound [TRUS] - guided prostate biopsy. Seventy-five patients were r and omized to receive an injection with bupivacaine, a lidocaine / bupivacaine combination, or no local anesthesia. 5 ml of anesthetic was injected immediately before biopsy. After performing the biopsy, a visual analogue scale [VAS; 0-10] were given to patients to assess the severity of pain during the biopsy procedure. In the bupivacaine group, the mean VAS scores were 2.04, and 4.46 in the control group with no local anethsesia [p<0.001]. bupivicaine provides immediate and significant periprostatic anesthesia for TRUS prostate biopsy

Intraoperative ketamine for the prevention of shivering post-trans urethral resection of prostate

To assess the effect of intraoperative ketamine in preventing post-anesthetic shivering. Eighty patients classified by the American society of anesthesiologists as class 2 and 3, scheduled for elective trans urethral resection of prostate under general anesthesia, were included in this study. Patients were assigned in a random manner to be given normal saline 0.9% as a placebo [group 1, n =37] or ketamine 25mg intravenously [group 2, n = 43] at the end of surgery prior to laryngeal mask airway removal. An anesthetist graded post- anesthetic shivering using a 5- point scale.]. The two groups did not differ significantly regarding patients demographics. Ketamine significantly reduced the incidence and severity of post-anesthetic shivering in comparison with placebo, on arrival in the recovery room and at regular intervals postoperatively. Our results suggest that intraoperative ketamine is effective in the prevention of post- anesthetic shivering
