Clinical Trial 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.

Description:

Following lower extremity orthopaedic surgeries, acute postoperative pain management plays a crucial on each patient's quality of recovery. Postoperative pain are usually classified as nociceptive, neuropathic, mixed, psychogenic, or idiopathic and so, a single treatment might be insufficient to treat it adequately. Multimodal analgesia, encompassing techniques such as the neuraxial blockade, peripheral nerve blocks, infiltration, patient-controlled opioid analgesia, and nonsteroidal anti-inflammatory drugs (NSAIDS), has been extensively investigated with aims to relieve postoperative pain. Lumbar Plexus Block (LPB) and Sciatic Nerve Block (SNB) are peripheral nerve block techniques consisting of the two large nerve branches that innervate the lower leg area. The combination of these two blocks (LPB-SNB), guided by ultrasonography (USG), blocks pain sensation throughout the lower extremity, and has been studied as an effective multimodal analgesia technique to relieve postoperative pain. This technique can minimize postoperative pain and also reduce the amount of opioid consumption, thereby reducing the incidence of postoperative nausea and vomiting (PONV). Patients' opinions of their medical care are the subject of an expanding array of assessment instruments being developed to gauge the level of postoperative recovery. The QoR-40 questionnaire is gaining popularity due to considerable validation of its utility in measuring quality of recovery. This questionnaire is appropriate for its intended use, responsive to changes in the therapeutic setting, and can yield reliable findings. The QoR-40 is a useful tool for assessing the anaesthesia and postoperative recovery quality in patients undergoing peripheral nerve blocks as well as in ordinary clinical practice. Nonetheless, there is currently limited research using the QoR-40 questionnaire to assess the quality of recovery in studies evaluating the efficacy of peripheral nerve blocks. This randomised controlled, double-blind and single-center trial will be conducted in a tertiary care hospital with aims of evaluating the efficacy of combined LPB-SNB compared to the traditional intravenous opioid in providing adequate analgesia after lower extremity orthopaedic surgeries with spinal anaesthesia with its primary outcome being the patient's postoperative quality of recovery as assessed by the QoR-40 questionnaire.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Postoperative Quality of Recovery as assessed by the QoR-40 questionnaire	The QoR-40 questionnaire is gaining popularity due to considerable validation of its utility in measuring quality of recovery. The QoR-40 questionnaire has 40 questions divided into 5 assessment dimensions, namely comfort (12 questions), emotions (9 questions), physical independence (5 questions), support (8 questions) and pain (6 questions), where each question has a value of 1 to 5 based on the Likert scale.	24 hours postoperatively
Secondary	Postoperative Intravenous Opioid Consumption	Total opioid consumption within 24 hours after lower extremity orthopaedic surgery (in milligrams).	24 hours postoperatively
Secondary	Postoperative Analgesia Duration	The duration of the postoperative analgesia, measured from the time the surgery was done (control group) or combined block was given (combined LPB-SNB group) till the time when participant first presses the PCA button in request of intravenous opioid (in minutes)	Within 24 hours postoperatively
