Abstract:

Objective: We aimed to evaluate the quality of anesthesia of combined sciatic and femoral 3-in-1 nerve blocks (CSFB) and unilateral spinal anesthesia technique with low-dose levobupivacaine in outpatients undergoing knee arthroscopy surgery. Materials and Methods: Forty American Society of Anesthesiologists (ASA) physical status I-II patients were randomly allocated into two groups and unilateral spinal anesthesia with low-dose levobupivacaine (group S, n=20) or CSFB (group B, n=20) was performed. Besides the quality of anesthesia, anesthetic effectiveness, hemodynamic values, duration of the technique application, maximum motor and sensorial block levels and durations, the first analgesics need, and total analgesic consumptions during postoperative 24 hours and determined complications were compared between the two groups. Results: The quality of anesthesia was better in group S, no patient received either sedation or analgesic intraoperatively while first analgesic need and number of patient was higher (p=0.014, p<0.001, p=0.032 respectively). The duration of technical application was shorter while maximum motor and sensorial block levels were higher in group S (p<0.0001, p=0.008, p<0.001 respectively). Motor block duration was significantly longer in group B (p<0.0001). Conclusion: We concluded that CSFB practice is an effective anesthetic alternative for unilateral spinal anesthesia.
