Interventions

Intervention1: Erector Spinae Plane (ESP) block: Performed at the L1 vertebral level under ultrasound guidance with Inj. Bupivacaine (0.25%) 20ml, before the start of the surgery after the induction o

Eligibility

Inclusion criteria

Inclusion criteria: 1. Adult patients (Age >18 years and 2. Patients who can understand and provide a valid consent for the procedure and also can understand and are willing to report the pain using VAS score.

Exclusion criteria

Exclusion criteria: 1. Patients who are currently suffering from chronic pain syndromes and are already under treatment with daily analgesics. 2. Patients in whom multiple nephrostomy tracts have been used, bilateral PCNL is undertaken or in whom conversion of the procedure to open surgery or extension of the normal procedure is required (e.g. second look nephrostomy). 3. Patients in whom the anatomy of the anaesthetic injection site is not clearly delineable on ultrasound examination due to any reason. 4. Patients who remain intubated/ sedated in the SICU post procedure and cannot participate in reporting the VAS score.

Design outcomes

Primary

Measure	Time frame
1. To compare the total dose (in mg) of Injection Tramadol required to achieve adequate analgesia (VAS score less than 5) in the total period of 24 hrs post PCNL in the patients receiving ESP block and in the control group.Timepoint: At the end of 24hrs post surgery	—

Secondary

Measure	Time frame
1. To compare the Visual Analog Scale (VAS) score and the Dynamic Visual Analog Scale (DVAS) score at 2 hrs, 12 hrs and 24 hrs post PCNL in patients receiving ESP block and in the control group.Timepoint: 2hrs, 12hrs and 24hrs post surgery;2. To compare the time to the first demand of rescue analgesia (VAS score â?¥ 5) using Inj. Tramadol (an opioid analgesic) post-recovery from general anaesthesia after PCNL in the patients receiving ESP block and in the control group.Timepoint: Single time point, varies across the study participants, data collected at the end of 24hrs	—
