Neuro-muscular blocking agents are currently administered to the fetus during intrauterine procedures, in order to freeze fetal movements and to avoid traumatic effects. The authors have evaluated three drug regimens (Pancuronium, Vecuronium, Atracurium), both via the intramuscular and the intravascular route of administration to the fetus. The time lapse between injection and disappearance of movements and the duration of paralysis have shown no significant differences for each group. The duration of fetal immobilization, on the other hand, has resulted excessively long for the necessity of the procedure. The authors speculate that immaturity of fetal metabolism can be responsible for the prolonged action of the drug. No side effect related to paralysis have been recorded at birth and after two years follow-up.

UI MeSH Term Description Entries
D010197 Pancuronium A bis-quaternary steroid that is a competitive nicotinic antagonist. As a neuromuscular blocking agent it is more potent than CURARE but has less effect on the circulatory system and on histamine release.

D003473 Neuromuscular Nondepolarizing Agents Drugs that interrupt transmission at the skeletal neuromuscular junction without causing depolarization of the motor end plate. They prevent acetylcholine from triggering muscle contraction and are used as muscle relaxants during electroshock treatments, in convulsive states, and as anesthesia adjuvants.
