Abstract
Background and objectives Ultrasound-guided femoral and popliteal sciatic nerve blocks are useful adjuncts for many below-knee procedures like debridement, amputation, etc. The objectives of the study were to find the efficacy and feasibility of the ultrasound-guided combined femoral and popliteal sciatic nerve block for below-knee procedures in the Emergency Medicine Department (ED). Methodology This prospective clinical study was carried out over three months in ED. A total of 30 patients undergoing below-knee procedures were included in the study. Femoral and popliteal sciatic nerve blocks were administered to each patient using the high-frequency linear ultrasound probe by emergency physicians trained in ultrasound. The effect of blocks, amount of local anesthetic (LA) used, duration of the procedure, and post-block analgesia were recorded. Patients were monitored for possible complications, if any. Data were entered and analyzed using a Microsoft Excel worksheet. Results The average volume of LAs required was around 34.5 cc for both blocks combined. No complications like vascular puncture or nerve injury were reported during the study. The time taken to complete the procedure was around 33 minutes, and the average time to achieve sensory block was around 9 minutes after completing the procedure. Conclusions An ultrasound-guided combined femoral and popliteal sciatic nerve block is an effective and feasible procedure and thus should be considered in ED for below-knee procedures.
