| Comparator Agent |
Erector Spinae Plane Block |
After administration of general anaesthesia, in prone position, the T11 vertebra will be identified by counting upwards from the L3-L4 interspace at the Tuffier’s line (highest point of the iliac crest). A low- or high-frequency linear probe will be placed in the midline in the longitudinal orientation. The transverse process of T11 will be identified by sliding the probe laterally, 3-4 cm away from the midline. A B. Braun Stimuplex Ultra 360° 100 mm needle will be inserted in-plane and advanced until the tip comes in contact with the lateral edge of the transverse process. The goal is to place the local anaesthetic between the transverse process and the erector spinae muscle overlying it. 30 ml of 0.25% Bupivacaine with 8mg Dexamethasone will be injected at in small aliquots after confirming negative aspiration for blood. The spread of the drug will be visualised as it lifts the erector spinae muscle off the bony shadow of the transverse process.

| Intervention |
Transmuscular Quadratus Lumborum Block |
After administration of general anaesthesia, in prone position, a low-frequency curvilinear USG probe will be placed in the transverse plane just above the iliac crest at the posterior axillary line, corresponding to the transverse process of L4 vertebra. The ‘Shamrock sign’ will be identified. Under USG guidance, a B. Braun Stimuplex Ultra 360° 100 mm needle will be inserted in-plane and allowed to traverse through the quadratus lumborum (QL) muscle until the tip pierces the epimysium of the muscle and lies in the interspace between the QL muscle and the psoas major along with the transversalis fascia. 30 ml of 0.25% Bupivacaine with 8mg Dexamethasone will be injected at this point in small aliquots after confirming negative aspiration for blood.

Brief Summary
|
Percutaneous Nephrolithotomy (PCNL) is currently one of the most efficient and commonly performed urological procedures and is the gold-standard treatment modality for large renal stones. Despite limiting the size of the skin incision, the use of continuous irrigation causing pelvicalyceal dilatation and the insertion of a nephrostomy tube can result in severe postoperative pain for the patient which further contributes to restricted ambulation, prolonged recovery and a longer hospital stay. Given the frequency at which the surgical procedure is being performed, it is essential that we investigate and identify the best possible method of providing analgesia for these patients. Regional anaesthesia provides many benefits including ease of performance, remarkable safety profile and decreased opioid consumption. The gold standard approaches to pain management in PCNL surgeries are epidural analgesia and thoracic paravertebral blocks, however the technically complexicity and associated complications have lead to the emergence of simpler and effective regional blocks. Literature review has revealed that the transmuscular quadratus lumborum block (TQLB) and the erector spinae plane block (ESPB) have shown much promise when compared to other regional techniques or the use of opioid analgesia. However, there has never been a published study comparing the efficacy of these two regional approaches for PCNL surgery. With this study we aim to compare the analgesic efficacy of TQLB and ESPB in patients undergoing PCNL surgery. |
