Comparative Randomized study of Erector Spinae Plane Block (ESPB) v/s Quadratus Lumborum Block (QLB) for post-operative analgesia in patients undergoing Percutaneous Nephrolithotomy (PCNL) surgery

After getting approval from Institutional Ethical Committee (IEC), those  patients who are fit in inclusion criteria will be included in our study.

Two groups both including 35 patients will be created and randomization will be done using chit and box method

Group E will undergo ESPB, Group Q will undergo QLB

Spinal anaesthesia will be given as per the institution’s protocol.

After surgery, QLB or ESPB will be performed under the guidance of a ultrasound machine (curvilinear probe) with 10 cm echogenic needle and 30 ml 0.25% bupivacaine will be injected.

The patient will be shifted to PACU and standard analgesia (1 gm PCM 8 hrly i/v) will be given as per standard institute protocol.

VAS score and haemodynamic parameter will be assessed at the end of surgery every hr for the first 6hrs then after12hrs, 18hrs, and 24hrs.

VAS >4 will be given rescue analgesia in form of I/V tramadol (1.5mg/kg).

Total rescue analgesic consumption in 24 hrs and complications will be noted.

Data will be analyzed using the appropriate statistical method.
