Brief Summary

Ondansetron, a selective serotonin 5-HT3 receptor antagonist, is well known for its antiemetic effects. However, its ability to reduce hypotension during spinal anesthesia has recently sparked great interest. In clinical practice, administering ondansetron before spinal anesthesia has produced promising results.

Outcome Measures

Primary Outcomes (1)

  • Ephedrine

    Total intraoperative ephedrine consumption.

    From the time of spinal anaesthesia administration till the end of surgery not exceeding two hors

Secondary Outcomes (1)

  • Nausea and vomiting

    From the time of end of surgery till the pass of the first 24 hours postoperatively

Study Arms (2)

Ondansetrone

ACTIVE COMPARATOR

will receive 8 mg of ondansetron (ZOFATRONE®, 8 mg/4 mL, EVA Pharma, Egypt) over 100 ml of normal saline solution over 10 minutes, starting with skin preparation for spinal anesthesia via the intravenous axis and a rapid intravenous (IV) infusion of 15 mL/kg of Ringer's solution that will be co-loaded during spinal anesthesia.

Drug: Ondansetron 8mg

Saline

PLACEBO COMPARATOR

will be managed by administering 100 ml of normal saline solution over 10 minutes, starting with the skin preparation for spinal anesthesia via the intravenous axis and a rapid intravenous (IV) infusion of 15 mL/kg of Ringer's solution that will be co-loaded during spinal anesthesia.

Drug: Normal Saline
