Study Overview
Brief Summary
This study will be a prospective randomised, double blinded, parallel group, single hospital, comparative study comparing the effects of ultrasound guided erector spinae plabe block versus ultrasound guided retrolaminar block on post operative analgesia in patients undergoing percutaneous nephrolithotomy. The null hypothesis of our study is that there is no difference in the duration of analgesia after erector spinae plane block and retrolaminar block in patients undergoing percutaneous nephrolithotomy.
AIM: To compare the analgesia after ultrasound guided unilateral retrolaminar block with ultrasound guided unilateral erector spinae plane block in patients undergoing percutaneous nephrolithotomy.
PRIMARY OBJECTIVE: To compare the duration of analgesia , that is, the time from injection of the drug administration to the patients first request for rescue analgesia or NRS score > 4, between two groups.
SECONDARY OBJECTIVE:
-
To compare the pain NRS scores at rest and during cough postoperatively after extubating, between two groups.
-
To calculate the total analgesic requirement in first 24hours between two groups.
-
To compare any complications, like , post operative nausea and vomiting, post operative shivering, pneumothorax and any other between the two groups.
