Outcome Measures

Primary Outcomes (1)

  • Total consumption of norepinephrine during the whole surgical procedure.

    Comparison between total amount of vassopressor used to maintain normal blood pressure in both groups of study

    Just after subarachnoid block till the end of surgery

Secondary Outcomes (1)

  • Incidence of hypotension, hemodynamic data and postoperative complications(nausea,vomiting,hypertension and bradycardia).

    Just after subarachnoid block till 24 hours postoperative

Study Arms (2)

Ondansetron (Zofran)

ACTIVE COMPARATOR

Ondansetron will be given intravenously in a dose of 0.1mg/kg 10 minutes before spinal anaesthesia as single shot

Drug: Ondansetron (Zofran)

Saline placebo

PLACEBO COMPARATOR

Normal saline will be administered by intravenous infusion 10 minutes before spinal anaesthesia

Drug: Saline (NaCl 0,9 %) (placebo)

Interventions

Ondansetron will be given intravenously in a dose of 0.1mg/kg 10 minutes before spinal anaesthesia as single shot.

Ondansetron (Zofran)

normal saline infusion will be given intravenously 10 minutes before spinal anaesthesia
