About this trial
This study aims to compare the effect of ondansetron lozenge and intravenous for prevention of shivering in cesarean section (CS).

Treatments tested in this trial
Ondansetron lozenge
DrugPatients will receive ondansetron lozenge 4 mg (Ondalenz ©), 2 hours before surgery.
Ondansetron intravenous
DrugPatients will receive 8 mg of ondansetron IV just before the surgery.
Treatment groups
Trial outcomes
Primary outcomes
Incidence of shivering
Shivering will be graded during the intraoperative and postoperative period using the scale validated by Crossley and Mahajan and Tsai and Chu. 0 No shivering 1. Piloerection or peripheral vasoconstriction but no visible shivering 2. Muscular activity in only one muscle group 3. Muscular activity in more than one muscle group but not generalized shivering 4. Shivering involving the whole body
Secondary outcomes
Incidence of postoperative nausea and vomiting
The incidence of nausea and vomiting will be evaluated through the Bellville scoring scale (lack of nausea and vomiting=0, nausea=1, nausea with belching=2, and vomiting=3).
Degree of patient satisfaction
Degree of patient satisfaction will be assessed on a 5-point Likert scale patient satisfaction (1, extremely dissatisfied; 2, unsatisfied; 3, neutral; 4, satisfied; 5, extremely satisfied).
Incidence of adverse effects
Incidence of adverse effects such as bradycardia, hypotension, respiratory depression, or any other complication will be recorded.
