This is a prospective, randomized, patient blinded trial of standard surgical retraction versus Mobius® retraction at cesarean delivery. Women will be approached by their provider at their 36 week prenatal visit regarding potential study participation. They will be given a letter describing the study. If a woman is interested, she will be contacted by a study nurse who will obtain informed consent. Ideally, women will be approached prior to the onset of labor or date of scheduled cesarean delivery so as to provide adequate time to review the study and ask questions. Women who undergo antenatal admission will be also approached by their provider regarding possible study participation and given a recruitment letter. If they are interested, then a study nurse will obtain informed consent.
Consenting women will be randomized after the decision to deliver by cesarean section is made. Randomization will be performed in blocks to control for scheduled versus unscheduled cesarean deliveries using a random numbers generator. Assignments will be kept in sequentially number opaque envelopes. Women will not be informed of their assignment until after discharge from the hospital. Efforts will be made in the operating room to avoid disclosing group assignment and the consent forms will not contain the specific name of the retractor under study. The operative team will be aware of group assignment.
Participants will complete a 7 item pain scale each post-operative day until discharge. This pain scale has been used in a pilot study and found to be accurate. The pain scale is a single page and takes less than 5 minutes to complete.
Charts will be reviewed to obtain clinical information which may have an impact on post-operative pain. This includes information about current and past substance abuse. Because of the increased amounts of post-operative pain experienced by women who use methadone during pregnancy, this group of women will be excluded from the study. To protect the information regarding substance abuse, a certificate of confidentiality has been obtained from the NIH.

No Intervention: Control
This arm will be randomly assigned to have conventional retractions (ie Rich retractors and similar) used in the usual fashion during the cesarean procedure.
This arm will be randomized to have the providers who are performing the cesarean section use the Mobius retractor during the cesarean section procedure after the peritoneal cavity is opened.
Device: Mobius Retractor
The Mobius retractor is a dual ring elastic self retaining retractor that is inserted into the abdominal cavity after the peritoneal incision has been established. It is then left in place during the hysterotomy incision, delivery of the fetus, hysterotomy repair, inspection and irrigation.
- The Degree of Pain With Activity on Post-operative Day Number Two [ Time Frame: 2 days ]Visual analog scale (VAS) of pain with activity on a scale of 0-15cm with 0cm: No pain to 15cm: Severe pain.
- Number of Participants Who Report Asymmetrical Pain on Second Post-operative Day After Cesarean Delivery [ Time Frame: 2 days post-operation ]Visual analog scale will be used to assess pain on the right or left side of the body with activity.VAS will use a 0-7.5cm range on the right and 0-7.5cm range on the left. This scale is with 0 (or central mark) as no pain and increasing as the subject marks away from the central mark.
