Measure
Lidocaine Patch Group
This group will be women who were randomized to receive a lidocaine patch for postoperative pain following cesarean delivery in addition to routine postoperative pain management. Lidocaine patch: Lidocaine patch to be placed in post-operative recovery area and used in addition to routine post-cesarean delivery pain management
Control Group
This group will be women randomized to routine postoperative pain management following cesarean delivery. A placebo patch will be placed superior to the Pfannenstiel incision in the same manner as the lidocaine patch treatment group.
