Brief Summary

This study aims to compare the ultrasound-guided transversalis fascia plane (TFP) block and intrathecal morphine for postoperative analgesia in patients undergoing total abdominal hysterectomy (TAH).

Detailed Description

Total abdominal hysterectomy (TAH) is a commonly performed major surgical procedure that results in substantial postoperative pain and discomfort. Postoperative pain, if not treated promptly, can impair the patient's ability to ambulate which may lead to adverse effects such as thromboembolism, myocardial ischemia, and arrhythmia.

Intrathecal opioids are synergistic with local anesthetics and intensify the sensory block without increasing the sympathetic block. Morphine, which is relatively less hydrophobic than other opioids, has a longer residence time in the cerebrospinal fluid and therefore may reach rostral sites over a longer period than other opioids.

Ultrasound-guided interfascial plane blocks are often used in multimodal analgesia regimens. Local anaesthetic injection into the transversalis fascia plane (TFP) anesthetizes the proximal branches of T12 and L1 which targeted in the plane between the transversus abdominis muscle and the transversalis fascia.

Arm && Interventions

Group	Intervention	Description
TFP group	Transversalis fascia plane block	Patients will receive spinal anesthesia (using 3.5 mL of hyperbaric bupivacaine 0.5%) with bilateral transversalis fascia plane (TFP) block (using 20 mL of bupivacaine 0.25%) at the end of surgery.
IM group	Morphine	Patients will receive spinal anesthesia (using 3 mL of hyperbaric bupivacaine 0.5%) + (75 µg morphine diluted in 0.5ml saline) with sham block at the end of surgery.

Primary Outcome Measures

Name	Time	Method
Time to the 1st rescue analgesia	24 hours postoperatively	Time to the first request for the rescue analgesia (time from the end of surgery to first dose of morphine administrated).

Secondary Outcome Measures

Name	Time	Method
Total morphine consumption	24 hours postoperatively	Rescue analgesia of morphine will be given as 3 mg bolus if the numeric rating scale (NRS)\> 3 to be repeated after 30 min if pain persists until the NRS \< 4.
Degree of pain	24 hours postoperatively	Each patient will be instructed about postoperative pain assessment with the numeric rating scale (NRS). NRS (0 represents "no pain" while 10 represents "the worst pain imaginable"). NRS will be assessed at post-anesthesia care unit (PACU), 2, 4, 6, 8, 12, 18, and 24 h postoperatively.
Incidence of adverse events	24 hours postoperatively	Incidence of adverse events such as bradycardia, hypotension, pruritis, nausea, vomiting, respiratory depression, or any other complication will be recorded.
