The Effect of Inhalational Agents on the Uterine Tone

Inhalational agents on the uterine tone will relax the uterus. Sometimes this is advantageous when you have a situation where the urs needs to be relaxed like an uterine inversion or if you really need to get a fetus out. This can cause diffusion hypoxia in the infant so any neonate that is exposed to nitrous oxide prior to delivery should have supplemental oxygen immediately after delivery.
