Abstract
Background
Cesarean section rate increased those days and postoperative pain control. The goal of postoperative pain management is provision of comfort, early mobilization and improved respiratory function without causing inadequate sedation and respiratory compromise, which can be achieved through using multimodal analgesic therapy, preference for regional techniques, avoidance of sedatives, non-invasive ventilation with supplemental oxygen and early mobilization.
Objectives
The aim of this study was to assess the analgesic efficacy of ultrasound-guided trans-muscular QLB compared with TAP block after cesarean section surgeryperiod regarding pain relief, provision of comfort, and improved respiratory functions.
Patients and Methods
After approval of anesthesiology department scientific and ethical committees in Ain Shams University Hospitals, female patients were included in the study, and were divided into three groups (n = 20; each); group QLB and group TAP. Group QLB: Patients (n = 20) of this group received bilateral ultrasound-guided QLB after induction of general anesthesia using 0.2 ml/kg bupivacaine 0.125%, Group TAP: Patients (n = 20) of this group received bilateral ultrasound-guided TAP block after induction of general anesthesia using 0.2 ml/kg bupivacaine 0.125%.
Results
The current study also measured and compared postoperative VAS score and firs time to rescue analgesia and the total amount of opioid (pethidine) given in the first 24 hours with the standard deviation for each of the two groups studied we found that TAP patients had the highest values compared to the QLB group. This is mainly due to the extension of the local anesthetic agent beyond the transverse abdominal plane to the thoracic paravertebral space, which then results in more analgesia, even somatic and visceral pain control.
Conclusion
Quadratus lumborum block was the most effective technique in providing analgesia after cesarean section without associated hemodynamic instability in comparison to transversus abdominis plane block and even more time covering to rescue opioid.
