But in a logistic regression analysis, use of the shoulder dystocia protocol was still associated with a reduced risk of obstetric brachial plexus injury.
The interval between delivery of the infant's head and body in cases of shoulder dystocia was longer in the posttraining period than in the pretraining period (2.0 minutes vs. 1.5 minutes).
“We wanted everyone to go slowly, so we were actually happy to see that the head-body interval went up,” commented Dr. Inglis. “That certainly didn't seem to worsen the risk of Erb's palsy.”
Study results also showed that staff were more likely to use the Rubin maneuver and posterior arm delivery in the posttraining vs. pretraining period, and were less likely to use the McRoberts maneuver.
