Abstract
Introduction Ultrasound-guided popliteal sciatic nerve block has been described as a safe and consistent form of regional anesthesia for foot and ankle surgery. Little studies have been performed to prove the effectiveness of surgeon self-administered regional anesthesia for foot and ankle injury requiring an operation. This study aimed to assess the applicability and safety in surgeon-administered ultrasound-guided popliteal sciatic nerve block in providing anesthesia for foot and ankle fracture. Material and Methods Patients with foot and ankle injury who underwent operation under surgeon-administered ultrasound-guided popliteal sciatic nerve block were evaluated in this retrospective study. A total of 7 patients (3 females and 4 males) with a mean age of 46) were evaluated by the diagnosis, side of injury, comorbidities in American Society of Anesthesiologists Classification (ASA), duration of operation, blood loss, pain control in visual analog scale (VAS) intra-operatively, degree of motor blockage, post-operative pain control and hospital length of stay. Result Average age of the study population was 46. Of all the patients, two of them were of ASA I four of them were of ASA II and one of them was of ASA III. Complete sensory and motor blockages were achieved for all patients. Average operative time was 117 min. Average blood loss was 16.4 mL. Average post-operative inpatient stay was 3.57 days. There was no regional anesthesia-related complication arising from the procedure. Conclusion Surgeon-administered popliteal sciatic nerve block is a safe procedure and can provide excellent pain control throughout the operation according to our experience. Foot and ankle fracture fixation can be performed by orthopedic surgeons under this technique.
