Pregnant women with BMI>40 will be approached for participation in a study to reduce the rate
of post-operative wound infection from C-section. Women will be randomized to a commonly used
wound product (Kerlix-AMD) which consists of a PHMB-impregnated gauze versus normal gauze,
and rates of post-operative surgical site infection will be assessed. Women with a planned
procedure will also be randomized to applying Kerlix versus gauze for 3 days pre-operatively
to determine if this improves outcomes as well.
