Effect of Intrathecal Morphine, Dexmedetomidine or Both in Combination to Bupivacaine on Immunity

Phase 1
Conditions
Immune System Suppression
Interventions
Registration Number
NCT03024957
Lead Sponsor
Assiut University
Brief Summary

this work aims to investigate the effect of intrathecal administration of Morphine, Dexmedetomidine or both in combination on cellular immunity and cytokine production in patients undergoing major abdominal cancer surgeries.

Detailed Description

Intrathecal (IT) adjuvants prolong the duration of spinal anesthesia and postoperative analgesia thereby reducing the requirement of postoperative supplemental analgesics. The incorporation of adjuvants also lowers the overall dose of local anesthetic and hence associated side effects. Morphine has been used widely to alleviate various types of pain and to supplement general anesthesia. On the other hand, morphine has been reported to possess some immunosuppressive effects. Postoperative immunity is also important in conjunction with defence against malignant tumour. Dexmedetomidine is a highly selective α2 agonist with analgesia, sedation, anxiolysis, and sympatholysis as its useful pharmacological actions. The extended analgesic efficacy of IT dexmedetomidine (ITD) in the postoperative period has been shown in a few clinical studies. In addition, current insights have identified that dexmedetomidine has a capacity in inhibiting the overproduction of a variety of inflammatory molecules including TNF-α, IL-1β, and IL-6 in several acute inflammatory animal models.
