Abstract

Open surgeries are associated with significant morbidities post operatively such as pain and restricted ambulation causing delayed recovery. A multimodal analgesic approach combining different analgesia modes with local or regional anaesthesia to maximise effectiveness is essential. Among the various regional anaesthesia techniques quadrates lumborumblock(QLB) is found to be an effective alternative. Aims:In this study we aim to assess the post operative analgesic efficacy of USG guided quadratuslumborum block in open urosurgical procedures. Materials and Methods : Ninety patients of ASA Grade I or II undergoing open urological procedures under GA were divided into 2 groups one group receive USG guided QLB(Group Q) and other control (Group C).Each patient was assessed for the duration of analgesia, (time to first rescue analgesic), total dose of rescue analgesics required in 24hrs,VAS score post operatively(1,2,4,6,8,12,18,24hrs) at PACU and the incidence of any adverse events post operatively. Results: The mean VAS score was higher in control group compared to both the study groups which was statistically significant(p value<0.0001).The mean time of demand for first rescue analgesia(duration of analgesia)was 4.87±1.01hrs in QLB group compared to control group 1.40± 0.50hrs which was statistically significant(p value<0.0001).The total rescue analgesic requirement was low in the study groups compared to control group(p value<0.0001).There was no incidence of any side effects found. Conclusion:Ultrasound guided QLB provide effective analgesia,decrease intraoperative and postoperative opiod consumption and is beneficial to shorten hospital stay in patients undergoing open urological procedures.
