Intrapartal tocolysis: an option for acute intrapartal fetal crisis

Tocolytic drugs are commonly used by the obstetric community to produce uterine quiescence in premature labor. The use of tocolytic agents has been expanded to intrapartal emergencies. Intrapartal tocolysis has implications for obstetric nurses, which include possession of knowledge of the pharmacologic and physiologic effects of these drugs. Intrapartal tocolysis offers a beneficial management strategy that can be used in an acute intrapartal fetal crisis. The use of tocolytics provides valuable time for the health care team to assess the etiology of a nonreassuring fetal heart rate pattern, increase options for the birth, and mobilize resources for delivery.
