Oxitocina en operación cesarean. ¿Que hay de nuevo?
Oxytocin in cesarean-sections. What's new?
Braz J Anesthesiol. 2016 Jul-Aug;66(4):402-7. doi: 10.1016/j.bjane.2014.11.015. Epub 2016 Apr 30.
Abstract
Oxytocin is the uterotonic agent of choice in the prevention and treatment of postpartum uterine atony. Nevertheless, there is no consensus on the optimal dose and rate for use in cesarean sections. The use of high bolus doses (e.g., 10IU of oxytocin) can determine deleterious cardiovascular changes for the patient, especially in situations of hypovolemia or low cardiac reserve. Furthermore, high doses of oxytocin for prolonged periods may lead to desensitization of oxytocin receptors in myometrium, resulting in clinical inefficiency.
