Effects of Different Anesthetic Agents on Surgical Site Hemorrhage During Circumcision.

PURPOSE: To investigate the effects of ketamine+midazolam and propofol+sevoflurane anesthesia on surgical site hemorrhage during circumcision procedures. MATERIALS AND METHODS: The boys undergoing circumcision surgery were included in the study. The patients were divided into two groups. In Group 1 (n = 50), 0.01 mg/kg midazolam and 2 mg/kg IV ketamine were administered. In Group 2 (n = 50), 1 ?g/kg fentanyl, 1 mg/kg lidocaine 2%, and 2-3 mg/kg IV propofol were administered, and patency of airway was ensured with a laryngeal mask airway. The intraoperative bleeding scale was recorded during the procedure to evaluate surgical site bleeding. Hemorrhage was checked for the first three hours using the postoperative bleeding scale to follow the amount of hemorrhage. RESULTS: Intraoperative bleeding scores were significantly higher in Group 1 as compared to Group 2. However, there was no significant difference between the groups regarding frequency of postoperative hemorrhage. Themean blood pressure values measured at 5th, 10th, 15th minutes and recovery room were significantly higher in Group 1. CONCLUSION: The intraoperative bleeding scores were significantly higher with ketamine+midazolam compared to propofol+sevoflurane. On the other hand this hemorrhage can be controlled easily with appropriate hemostasis, and the amount of blood loss was not clinically significant. We think that our study makes a positive contribution to the literature about the effects of anesthetics on the surgical site bleeding during circumcision.

The Effect of Peritubal Infiltration with Bupivacaine and Morphine on Postoperative Analgesia in Patients Undergoing Percutaneous Nephrolithotomy.

Objective. We aimed to investigate the effect of peritubal local anesthetic and opioid infiltration on pain scores and analgesic consumption in patients who underwent percutaneous nephrolithotomy. Material and Methods. Patients aged between 18 and 65 years and ASA I-III were included in this double-blind, randomized study. The patients were divided into two groups. All patients underwent spinoepidural anesthesia. 20 mL of 0.25 percent bupivacaine + 5 mg morphine (0.5 mL), in Group P (n = 66), infiltrated the renal capsule, perinephric fat, muscles, subcutaneous tissue, and skin under fluoroscopy. In Group C (n = 64), none of the patients received a peritubal injection. In the first 24 h pain scores, time of the first analgesic demand, the mean number of analgesic demands, and postoperative complications were compared between groups. Results. The mean VAS score at postoperative 8, 12, and 24 h and dynamic VAS score at postoperative 4, 8, 12, and 24 h were significantly lower in Group P. VAS score at postoperative 4 h was not significant. Time of the first analgesic demand was significantly longer in Group P. Conclusion. Our study results suggest that peritubal infiltration of bupivacaine with morphine after percutaneous nephrolithotomy is an effective method for postoperative pain control and reduces analgesic consumption.
