Primary Outcome Measures:

to determine the rate of wound infection using two standard wound preparations: povidone-iodine and chlorhexidine gluconate [ Time Frame: within 6 weeks following surgery ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

readmission to hospital [ Time Frame: within 6 weeks following surgery ] [ Designated as safety issue: No ]
extended length of admission [ Time Frame: within 6 weeks following surgery ] [ Designated as safety issue: No ]
need for intravenous antibiotics [ Time Frame: within 6 weeks following surgery ] [ Designated as safety issue: No ]
need for repeat procedure such as drainage [ Time Frame: within 6 weeks following surgery ] [ Designated as safety issue: No ]
increased outpatient surveillance [ Time Frame: within 6 weeks following surgery ] [ Designated as safety issue: No ]

Arms	Assigned Interventions
Active Comparator: A povidone-iodine	Other: povidone-iodine solution Abdominal surgical field cleaned with 5% povidone-iodine detergent scrub, detergent cleaned from surgical area with sterile water, and then painted with 1% povidone-iodine solution. Other Name: Betadine, Povidone, Minidyne
Active Comparator: B chlorhexidine gluconate	Other: chlorhexidine gluconate Abdominal surgical field painted once using 2% chlorhexidine in 70% alcohol. Other Name: Dexidine, Avagard, Bactoshield

Detailed Description:

Wound infection is a universal potential morbidity to any type of surgery. Over the years many studies have been completed to evaluate ways to decrease this morbidity. Recent literature has looked at different types of surgical solutions used in pre-operative cleansing. Chlorhexidine and povidone-iodine are two standard surgical prep solutions used on a global scale. The most recent literature has shown that chlorhexidine has a decreased wound infection rate for longer surgeries. Cesarean section, as a surgical time, varies from 20 - 60 minutes. There has been no known literature regarding wound infection rates using these two solutions in elective cesarean sections. This trial will review the rates of wound infection using chlorhexidine and povidone-iodine during elective cesarean section and determine if there is any statistically significant difference between the two solutions. The results could potentially decrease wound infection rates, decrease morbidity, decrease hospital length of stay, and help to guide further surgical management.
