Abstract

Background: Laparoscopic renal surgery (LRS), either via the retroperitoneal or transperitoneal approach, is a popular method for renal therapy. The present study assessed efficacy of analgesia with QLB in unilateral laparoscopic renal surgeries.
Materials & Methods: 50 patients of unilateral laparoscopic renal surgeries of both genders were divided into 2 groups of 25 each. Group I received QLB and group II received no block at the end of surgery. Morphine was administered in patient-controlled analgesia pump with a bolus of 1 mg and a lockout interval of 10 min (min). The total morphine consumption was recorded. The pain was assessed by a Visual Analogue Scale (VAS).
Results: Group I had 15 males and 10 females and group II had 12 males and 13 females. The mean age was 38.5 years in group I and 42.5 years in group II, height was 165.2 cm in group I and 164.4 cm in group II, weight was 70.4 kgs in group I and 72.1 kgs in group II, duration of surgery was 46.3 minutes in group I and 45.2 minutes in group II, ASA grade I was seen in 13 in group I and 15 in group II, grade II in 10 and 9 in group I and I and grade III in 3 and 1 in group I and II respectively. Total morphine consumption was 3.6 mg in group I and 9.1 mg in group II and duration of post- operative analgesia was 1124.3 minutes in group I and 147.6 minutes in group II. The difference was non- significant (p> 0.05).
Conclusion: There was less consumption of opioids following laparoscopic renal surgeries using Ultrasound-guided QLB.
