Epidural Steroids With Intrathecal Nalbuphine for Lower Abdominal Oncologic Surgery

Not Applicable
Completed
Conditions
Lower Abdominal Oncologic Surgery
Interventions
Drug: Placebo-nalbuphine
Drug: Dexamethasone-nalbuphine
Registration Number
NCT03276325
Lead Sponsor
Mansoura University
Brief Summary

Intraoperative pain, nausea, vomiting, hypotension, bradycardia are known side effects during lower abdominal surgery under spinal anesthesia, Time to 2 segment regression of sensory block and duration of effective analgesia prolonged with intrathecal (IT) 0.4 mg nalbuphine \& IT 0.8 mg nalbuphine, but the incidence of side-effects was significantly higher with IT 0.8 mg nalbuphine compared with (IT) 0.4 mg nalbuphine.

Detailed Description

So, the hypothesis of using IT nalbuphine mid away dose 0.6 mg between the best intraoperative analgesic effective dose 0.8 mg and the least side effect producing dose 0.4mg with the addition of epidural dexamethasone could augment the postoperative analgesia and reduce the unwanted side effects. Epidural dexamethasone in a full dose of 8 mg is probably more effective than lower doses to control moderate to severe post-operative pain. Dexamethasone 8mg dose is surgically safe neither produced delayed wound healing nor elevated blood glucose level.
