Outcome Measures

Primary Outcomes (3)

  • Assess the mean blood pressure

    Number of pregnant patients with obesity who present a decrease in mean arterial pressure after the administration of subarachnoid hyperbaric bupivacaine with doses of 5mg and 10mg during cesarean surgery

    3 hour

  • Determine the effects on the heart rate

    Number of pregnant patients with obesity who present changes in heart rate such as bradycardia (heart rate less than 60 beats minute) or tachycardia (heart rate greater than 120 beats minute) after administration of subarachnoid hyperbaric bupivacaine with doses of 5mg and 10 mg during cesarean surgery

    3 hour

  • Determine the effects on the O2 saturation

    Number of pregnant patients with obesity who present changes in O2 saturation after administration of subarachnoid hyperbaric bupivacaine with doses of 5mg and 10mg during cesarean surgery

    3 hour

Secondary Outcomes (4)

  • Describe the adverse effects (nausea or vomiting)

    3 hour

  • Identify the level of sensory blockade

    15 minutes
