patients will receive general anesthesia only.
patients will receive general anesthesia and bilateral ultrasound guided erector spinae plane block (20ml Bupivacaine 0.25%)
patients will receive general anesthesia and bilateral ultrasound guided quadratus lumborum block (20 ml Bupivacaine 0.25%)
The degree of postoperative pain in the first 24 hours post-operative
Postoperative pain will be assessed by the numerical rating scale (NRS); 0 no pain while 10 is the maximum pain) after discharge to the ward ,and at 6, 12, 18, 24 hours.
Time frame: first 24 hours post-operative
Time to first analgesic requirement
Intravenous morphine 2 mg will be given when the numerical rating scale (NRS) equal or above 4
Time frame: first 24 hours post-operative
Total dose of intraoperative consumption of fentanyl
Fentanyl 0.5 μg/kg will be given if there was increase in heart rate or mean arterial blood pressure more than 20% (after exclusion of other causes than pain).
Time frame: intraoperative
Total dose of rescue analgesia in the first 24hr postoperative
Total morphine consumption 24 hours after surgery will be recorded. Intravenous morphine 2 mg will be given when the numerical rating scale (NRS) equal or above 4
