Background: Open surgeries are associated with significant morbidities postoperatively such as pain and restricted ambulation causing delayed recovery. Among the various regional anesthesia techniques quadratus lumborum block (QLB) and erector spinae plane block (ESPB) are found to be effective alternatives.
Aims and Objectives: The study intended to assess the post-operative analgesic efficacy of ultrasound-guided (USG) guided QLB and ESPB in open urological procedures.
Materials and Methods: Ninety patients of ASA Grade I or II undergoing open urological procedures were divided into three groups. Group Q received USG-guided QLB, Group E received USG-guided ESPB and Group C received standard analgesia regimen. Each patient was assessed for the duration of analgesia, the total dose of rescue analgesics required in 24 h, Visual Analog Scale (VAS) score postoperatively (at 1, 2, 4, 6, 8, 12, 18, and 24 h) at post-anesthetic care unit and the incidence of any adverse events postoperatively.
Results: The mean VAS score was higher in the control group compared to both the study groups which was statistically significant (P<0.0001). The mean duration of analgesia was 4.87±1.01 h in Group Q and 5.13±1.01 h in Group E compared to Group C 1.40±0.50 h which was statistically significant (P<0.0001). The total rescue analgesic requirement was low in the study groups compared to the control group (P<0.0001). There was no incidence of any side effects found.
Conclusion: Both USG QLB and ESPB provide effective analgesia, decrease intraoperative and post-operative analgesic consumption, and are beneficial to shorten hospital stay in patients undergoing open urological procedures.
