Overview
Brief Summary
The aim of this prospective randomized controlled study is to compare the analgesic efficacy of the ultrasound-guided erector spinae plane block, ultrasound-guided quadratus lumborum plane block, and ultrasound-guided transversus abdominis plane block in patients undergoing elective cesarean section.
Detailed Description
Acute postpartum pain is a key determinant of maternal satisfaction; may lead to persistent postoperative pain. Opioids are used to control severe pain. However, they have many common side effects as sedation, dizziness, nausea, vomiting, constipation, physical dependence, tolerance, and respiratory depression. Transversus abdominis plane (TAP) block is a regional injection of local anesthetic between the transversus abdominis and internal oblique muscle planes. TAP block affects the sensory nerves of the anterolateral abdominal wall (T6-L1) that innervate the abdomen. TAP block is an easy technique, and decreases postoperative pain and opioid consumption. Erector Spinae Plane block (ESPB), first described for analgesia in thoracic neuropathic pain has also been reported for the management of other causes of acute postoperative pain. Quadratus Lumborum block (QLB) differ from the transversus abdominis plane block (TAP) it is a block of the posterior abdominal wall. It is also referred to as an inter fascial plane block because it requires the injection of a local anesthetic into the thoracolumbar fascia (TLF).

Outcomes
Primary Outcomes
Postoperative morphine consumption
Time Frame: 24 hours postoperatively
The rescue analgesia will be morphine IV bolus 3 mg with 5-minute lock out interval when Numeric Rating Scale (NRS)\>3, can be repeated till NRS˂3 guided with the occurrence of complication.
Secondary Outcomes
- Degree of patient satisfaction(24 hours postoperatively)
- Time for first request of the rescue analgesia(24 hours postoperatively)
- Complications(24 hours postoperatively)
- Degree of pain(24 hours postoperatively)
