Dm. Sherer et al., RESOLUTION OF MARKED INTRAPARTUM FETAL TACHYCARDIA FOLLOWING INTRAVENOUS NALBUPHINE HYDROCHLORIDE, American journal of perinatology, 11(5), 1994, pp. 367-368
We report a case of a patient who received nalbuphine during labor. Th
e fetus was in an awake state, but when exposed to intravenous nalbuph
ine manifested quiet sleep. This suggests a physiological response and
not a sign of fetal compromise.
