Effect of Preoperative Intrathecal Dexamethasone Versus Dexmedetomidine on Paralytic Ileus After Major Abdominal Surgery

Postoperative Ileus (POI) is considered as intolerance of oral intake due to disruption of the normal coordinated propulsive motor activity of the gastrointestinal (GI) tract following abdominal or non-abdominal surgery. Dexamethasone & Dexmedetomidine have been reported to attenuate the incidence of paralytic ileus after abdominal surgeries. Previous study has shown that a single dose of DM before induction of anesthesia may be beneficial to reduce ileus for IBD by alleviating the postoperative systemic inflammatory response. Perioperative dexmedetomidine in major abdominal surgeries significantly decreased the time to flatus, defecation, and resuming normal diet, shortened length of stay, and improved haemodynamic stability. The aim of this study is to compare the effect of preoperative intrathecal dexamethasone versus dexmedetomidine on paralytic ileus after major abdominal surgery.
