Background. Sciatic and femoral nerve blocks (SNB and FNB) result in effective lower limb analgesia. Classical SNB and FNB require patient repositioning which can cause pain and discomfort. Alternative approaches to sciatic and femoral nerve blocks in supine patients can be useful. Materials and Methods. Neurostimulator-guided SNB and FNB from the lateral supratrochanteric approach were performed. Local anesthetic spread in SNB and FNB after radiographic opacification was analyzed. Time and number of attempts to perform blocks, needle depth, and clinical efficacy were assessed. Results. Mean needle passes number and procedure time for SNB were 2.5 ± 0.3 and 2.4 ± 0.2 min, respectively. Mean needle passes number and procedure time for FNB were 2.7 ± 0.27 and 2.59 ± 0.23 min, respectively. Mean skin to nerve distance was 9.1 ± 0.45 cm for SNB and 8.8 ± 0.5 cm for FNB. Radiographic opacification of SNB showed local anesthetic spread close to the sacrum and involvement of sacral plexus nerve roots. Spread of local anesthetic in FNB was typical. Intraoperative fentanyl administration was required in 2 patients (9.5%) with mean dose 1.8 ± 0.2 mcg/kg. Mean postoperative pain score was 0.34 ± 0.08 of 10. Conclusion. The lateral supratrochanteric approach to SNB and FNB in children can be an effective lower limb analgesic technique in supine patients. The trial is registered with ISRCTN70969666.
