Although essential there has been no detailed review of potential side effects.

Two pups of each horn were randomized to an ultrasound guided injection with medication (atropine\u2010cisatracurium\u2010fentanyl, as clinically used) or saline (sham). The third pup was used as control. At term, does were delivered by cesarean.

Both motor and sensory neurobehavioral scores were comparable. There were no differences in neuron density or proliferation.
