NCT00573963

Brief Summary

The purpose of this study is to determine if patients having the transversus abdominal place (TAP) block at the end of a cesarean delivery have less pain in the post-delivery period than those who do not. Freezing medication is injected between the layers of muscle on either side of the belly, to freeze the nerves that carry pain stimuli from an abdominal wound. This technique has been useful for many abdominal operations, and has recently been studied in cesarean sections, however more information is needed.
