this study is designed to compare intrathecal bolus of bupivacaine-dexmedetomidine versus
continuous epidural fentanyl infusion in providing effective operative analgesia,
intraoperative hemodynamic stability and less postoperative cumulative opioid induced
complications in orthotopic urinary bladder diversion prolonged surgery.
The hypothesis Intrathecal bolus of bupivacaine-dexmedetomidine could replace continuous
epidural fentanyl infusion and would be an enough intraoperative analgesic modality with good
intraoperative hemodynamic stability and less postoperative complications in orthotopic
urinary bladder diversion patients.
Aim of the work The aim of this protocol is to document that intrathecal bolus of
bupivacaine-dexmedetomidine analgesia (a low coast analgesic modality) can replace continuous
epidural fentanyl infusion analgesic modality with effective operative analgesia,
intraoperative hemodynamic stability and less postoperative cumulative opioid induced
complications in orthotopic urinary bladder diversion prolonged surgery.
