Our experience of combined femoral sciatic nerve block in the lower extremity surgery

Objectives: In this study, the effectiveness of the combine femoral and sciatic nerve block in lower-extremity surgery was aimed to be investigated. Materals and methods: The patients with ASA I-III group, aged between 18-70 years, who underwent combinede sciatic femoral nerve block in lower-extremity surgery, were retrospectively evaluated.The study included 110 patients. The patients were divided into four groups according to the local anesthetic drugs used; Group I: 30 ml 0.5% Bupivacaine + 10 ml 0.9% NaCl, Group II: 30 ml 0.5% Levobupivacaine + 10 ml 0.9% NaCl, Group III: 30 ml 0.5% Levobupivacaine +10 ml 2% prilocaine HCl, GrupIV: 20 ml 0.5% Bupivacaine + 2 ml 2% Lidocaine HCl. The demographic data, clinical diagnosis, dose and volume of used local anesthetics, application time of the technique, duration of surgery, rates of block success, hemodynamic parameters before and after intervention, the first postoperative analgesic requirements (the first postoperative analgesic need, the amount of analgesic consumption of postoperative first 24 hours, developing complications during and after the process, patient’s and surgical satisfaction data of were recorded. Results: The demographic data of patient group were similar. No significant differences were found in terms of quality of surgical anesthesia and postoperative analgesia between different groups. The combined sciatic femoral nerve block was most frequently performed for ankle surgery. Different local anesthetics doses administered to patients were provided adequate anesthesia. Success of process was found to be 96%. Conclusion: The combined femoral sciatic nerve block applied with the success rate of 96%. The mean duration of adequate anesthesia and postoperative analgesia was 426 minutes.
