Brief Summary:
The purpose of this study is to find out if chlorhexidine gluconate solution is better at reducing the rate of wound infection after cesarean section compared to povidone-iodine.

Condition or disease Intervention/treatment Phase
Wound Infection Other: povidone-iodine solution Other: chlorhexidine gluconate Phase 3

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.

Primary Outcome Measures :
  1. to determine the rate of wound infection using two standard wound preparations: povidone-iodine and chlorhexidine gluconate [ Time Frame: within 6 weeks following surgery ]

Secondary Outcome Measures :
  1. readmission to hospital [ Time Frame: within 6 weeks following surgery ]
  2. extended length of admission [ Time Frame: within 6 weeks following surgery ]
  3. need for intravenous antibiotics [ Time Frame: within 6 weeks following surgery ]
  4. need for repeat procedure such as drainage [ Time Frame: within 6 weeks following surgery ]
  5. increased outpatient surveillance [ Time Frame: within 6 weeks following surgery ]
