Pethidine is widely used for shivering prevention and treatment, but it has serious side effects. Ondansetron has been suggested in several studies to prevent shivering with minimal side effects, although there are limited studies and its effectiveness compared to pethidine remains controversial, particularly in cesarean section cases.en-USCesarean SectionNausea and VomitingOndansetronPethidineShiveringThesis
