NCT03248817

Brief Summary

the investigators will compare variable infusion of phenylephrine (at a starting rate of 0.75 mcg/Kg/min) with fixed rate (0.75 mcg/Kg/min which will stop of reactive hypertension occurred) and single shot (1.5 mcg/Kg) phenylephrine

Conditions

Cesarean Section ComplicationsSpinal Anesthesia

Outcome Measures

Primary Outcomes (1)

  • Incidence of Post-spinal anesthesia hypotension

    Defined as percentage of patients with decreased systolic blood pressure less than 80% of the baseline reading during the period from intrathecal injection to delivery of the fetus.

    30 minutes after spinal anesthesia

Secondary Outcomes (6)

  • Incidence of severe Post-spinal anesthesia hypotension

    30 minutes after spinal anesthesia

  • Incidence of reactive hypertension

    2 hours after spinal anesthesia

  • systolic blood pressure

    2 hours after spinal anesthesia

  • diastolic blood pressure

    2 hours after subarachnoid block

  • heart rate

    2 hours after subarachnoid block

  • +1 more secondary outcomes

Study Arms (3)

single shot

EXPERIMENTAL

spinal anesthesia will be performed using intrathecal bupivacaine. Then, a single shot phenylephrine (1.5 ug/Kg) will be administered

Drug: single shot phenylephrineDrug: Bupivacaine

fixed infusion

ACTIVE COMPARATOR

spinal anesthesia will be performed using intrathecal bupivacaine. Then, fixed infusion phenylephrine will be administered at a dose of (0.75 mcg/Kg/min). the infusion will stop if reactive hypertension occurred

Drug: fixed infusion phenylephrineDrug: Bupivacaine

variable infusion

ACTIVE COMPARATOR

spinal anesthesia will be performed using intrathecal bupivacaine. Then, variable infusion phenylephrine will be administered at a starting dose of (0.75 mcg/Kg/min). the infusion will be titrated according to blood pressure

Drug: variable infusion phenylephrineDrug: Bupivacaine
