Comparison of Two Different Doses of Phenylephrine on Oxytocin Hemodynamic Effect

Cesarean Birth, Phenylephrine

Phenylephrine, Oxytocin induced hypotension

Cesarean section is one of the commonly performed surgical procedures in the world. Once baby is delivered during the surgical procedure anesthesiologist administer Oxytocin drug through IV cannula which helps the Uterus to contract so that excessive blood loss doesnt occur. But this is associated with fall in blood pressure frequently requiring administration of medications to treat low blood pressure. The most frequently used drug is phenylephrine which can administered along with oxytocin to prevent fall in blood pressure. This study will compare to different doses of Phenylephrine to prevent fall in blood pressure.

Cesarean section is one of the most commonly performed surgical procedures worldwide. Following delivery of the neonate, oxytocin is routinely administered intravenously to promote uterine contraction and thereby reduce the risk of postpartum hemorrhage. However, oxytocin administration is frequently associated with maternal hypotension, which may necessitate pharmacological intervention. Phenylephrine, a selective α-adrenergic agonist, is commonly used to prevent or treat oxytocin-induced hypotension due to its vasoconstrictive properties. The optimal prophylactic dose of phenylephrine administered concurrently with oxytocin remains uncertain. This study aims to compare two different doses of phenylephrine for the prevention of hypotension following oxytocin administration during cesarean section.
