Primary Outcome Measures :
  1. Intraoperative Nausea and Vomiting [ Time Frame: Intraoperatively ]
    Comparison of intraoperative nausea and vomiting between the 3 groups.

Secondary Outcome Measures :
  1. Postoperative Nausea and Vomiting (PONV) [ Time Frame: 0-2h, 2-6h, 6-24h ]
  2. Pruritus [ Time Frame: 0-24 hrs ]
  3. Satisfaction [ Time Frame: 24 h ]
    1=very satisfied, 2=somewhat satisfied, 3= neither satisfied nor dissatisfied, 4=somewhat dissatisfied, 5= very dissatisfied. Number of very satisfied subjects posted.

  4. Maternal Hemodynamics [ Time Frame: Intraoperatively ]
    The number of patients with systolic blood pressure decrease to less than 20 % of baseline intraoperatively
