Postoperative Quality of Recovery After Combined Lumbar Plexus-Sciatic Nerve Block (LPB-SNB)

Summary

The goal of this clinical trial is to evaluate the efficacy of lumbar plexus-sciatic nerve block (LPB-SNB) by comparing the postoperative quality of recovery as assessed by the Quality of Recovery-40 (QoR-40) questionnaire, in patients who received a combination of LPB-SNB versus patients who received the traditional intravenous opioid, after lower extremity orthopaedic surgeries with spinal anaesthesia. The main questions it aims to answer are: * Will there be a significant difference in QoR-40 scores between both groups? * Will the combined LPB-SNB significantly reduces opioid consumption within the first 24 hours? * Will the combined LPB-SNB significantly increases postoperative duration of analgesia? Participants will: * Receive a coded sealed opaque envelope containing their randomly allocated intervention group; first group receives a combination of lumbar plexus-sciatic nerve block, while the second group receives no block at all. This information would not be disclosed to the participants. * Receive an explanation on how to use the patient controlled analgesia (PCA) to deliver intravenous opioid, and instructions on filling in the QoR-40 questionnaire. Researchers will then compare the results between both groups to see if the combined lumbar plexus-sciatic nerve block successfully provides adequate analgesia and enhance postoperative quality of recovery after lower extremity orthopaedic surgeries.
