Popis: The direct effect of competitive and noncompetitive neuromuscular blocking agents on uterine contractions was observed in vitro. Exposure of human gravid myometrial strips to succinylcholine chloride, decamethonium iodide, gallamine triethiodide, and d -tubocurarine chloride in concentrations equivalent to one hundred times the paralyzing dose failed to significantly affect spontaneous or oxytocin stimulated contractions. By contrast, halothane produced complete inhibition of spontaneous contractions, which was completely reversed by discontinuance of the agent. These results support the contention that the role of neuromuscular blocking agents in the management of obstetric emergencies requiring uterine relaxation is limited to relaxation of the abdominal and perineal musculature, and to facilitation of anesthetic management.
