Spinal anesthesia affects the homeostatic systems resulting in intraoperative hypothermia and subsequently shivering. In fact, shivering may be seen after this technique in 30 to 40% of cases . Ondansetron and Nefopam have been used to prevent intraoperative shivering . However, no prospective, randomized, double-blind study has been conducted to this date in order to compare nefopam with ondansetron in the prevention of post-spinal anesthesia shivering. The primary objective of this prospective, randomized, double-blind study is to compare the incidence and intensity of shivering after spinal anesthesia for non-obstetric surgery in 2 groups of patients. Group A: Patients receiving 8 mg of ondansetron diluted in 20 ml of 0.9% normal saline over 30 minutes as they arrive to the operating theater(75 patients). • Group B: Patients receiving 20 mg of nefopam diluted in 20 ml of 0.9% normal saline over 30 minutes as they arrive to the operating theater (75 patients)
