Currently there is no study investigating optimal skin preparations patterns prior to cesarean deliveries. As a result, there are many practitioners that perform skin preparation, cleaning of the surgical site, using random unstudied patterns. Patterns vary from Hospital to Hospital and even within the same institution. The most widely used topical skin preparation is ChloraPrep and the manufacturer has not recommended a specific pattern to be used in order to abdominally prep prior to C-sections. They have published data instructing one on the surface area for which a ChloraPrep stick is verified to be used for as well as timing from initial preparation until the cleaner has reached its maximum antiseptic benefit. Our current cesarean infection rate is 1.6% over the last 12 months (September 2107-2018). This is significantly lower than the average cesarean section infection rate in the United States which is estimated to be around 7.4%.[i] Cesarean deliveries are one of the most common major surgeries performed in the united states, 31.9% of all births are by cesarean section.[ii] The risk of infection following a cesarean delivery is nearly 5 times that of a vaginal delivery[iii]. However, there is still no study that examines the pattern which ChloraPrep, the most widely used skin cleaner, is applied to the abdomen prior to a cesarean delivery. There is currently no study that looks at pattern of skin preparation prior to cesarean section. The manufacture simply recommends gentle scrubbing. The pattern of skin preparation appears to be related to your training. This study aims to look at topical skin preparation patterns prior to cesarean section. As a proxy for likelihood of infection the investigators will collect data on surface bacterial burden prior to incision but after abdominal prep is complete as well as post surgically. The assumption is that if there is a significant skin burden postoperatively that one method of skin preparation is superior to the other.
