I'm having trouble finding reliable information on this topic. I recently had a primip that progressed very quickly (from 3 to complete in a little over an hour) and thus she didn't have a chance to get the epidural she wanted. Just prior to pushing, the doc ordered 10 mg of nubain. Delivery was about 20 minutes later. He said it takes 2 hours for nubain to reach the baby and the nursing staff is divided on how quickly it happens. I was taught in school that giving nubain late in labor can cause lower APGARs. What's your opinion/experience/literature?
