Abstract
To evaluate the secondary outcomes, including heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), the time interval from injection of local anesthetic to first demand for analgesia, total tramadol consumption and the incidence of postoperative nausea and vomiting (PONV) and other side effects/complications, in patients receiving quadratus lumborum block versus transversus abdominis plane block. This study involved 20 participants undergoing Matta plate fixation for pelvic fractures, randomized to receive either quadratus lumborum block (QLB) or transversus abdominis plane block (TAPB). Key secondary outcomes assessed included heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), total tramadol consumption, time to first analgesic demand and incidence of postoperative nausea and vomiting (PONV). Measurements were taken at baseline and at 2, 4, 6, 12 and 24 hours post‐procedure. Statistical analyses included independent samples t‐tests to compare hemodynamic parameters and analgesic outcomes between the two groups, with a significance level set at p<0.05. In this study comparing quadratus lumborum block (QLB) and transversus abdominis plane block (TAPB) for abdominal surgeries, we found no significant differences in heart rate, diastolic blood pressure and most systolic blood pressure measurements between the two techniques at various time points (2, 4, 6, 12 hours). Notably, QLB was associated with a significantly lower systolic blood pressure at baseline (p=0.050) and a higher respiratory rate at 24 hours (p < 0.001) compared to TAPB. The QLB group also demonstrated significantly lower total tramadol consumption (55.00 mg vs. 190.00 mg, p<0.001) and a longer time to first analgesic demand (24.50 hours vs. 9.90 hours, p<0.001). There was no significant difference in the incidence of postoperative nausea and vomiting (PONV) between QLB and TAPB (p=0.178). These results suggest that QLB may offer superior analgesic efficacy and opioid‐sparing benefits while maintaining comparable gastrointestinal tolerability. The QLB group showed a significantly longer time interval to the first demand for analgesia and lower total tramadol consumption compared to the TAP group, indicating better pain control. While there were significant differences in SBP at baseline and 24 hours, no significant differences were observed in HR and DBP at various time points. The incidence of PONV did not differ significantly between the two groups. These results suggest that QLB may provide superior analgesia with lower opioid consumption compared to TAP block.
