Comparative study between Dexmedetomidine and Ondansteron for prevention of post spinal shivering. A randomized controlled trial.

Background: Regional anesthesia could affect the homeostatic system functions resulting frequently in perioperative hypothermia and consequently shivering. The objective of this trial was to evaluate the efficacy of dexmedetomidine and ondansetron to reduce the incidence and severity of shivering after intrathecal blocks.

Methods: This randomized placebo-controlled trial included 120 patients allocated equally in three groups.
