Increased Cefazolin (Ancef) Dosing for Prophylaxis During Cesarean Delivery in the Obese Population
In Brief
A Phase 4 clinical trial evaluating Cefazolin for Obesity and 3 related conditions. Completed, enrolled 30 participants across 2 sites.
Detailed Summary
The purpose of this study is to determine whether an increased prophylactic dose (3 grams) of cefazolin at the time of cesarean delivery has superior coverage in adipose tissue than the current established dosing of 2 grams. The tissue and serum concentration values, when using an increased prophylactic dose, can then be compared to our pilot study assays in hopes of determining an optimal dosing for the obese and morbidly obese populations undergoing cesarean delivery. A previous study performed at University of California, Irvine (UCI) and Long Beach Memorial Medical Center/Miller Children's Hospital (LBMMC) showed that the standard dose of antibiotics (2 grams of cefazolin) did not provide adequate coverage for all organisms in the obese and extremely obese populations. The purpose of this research study is to evaluate whether in increased dose of antibiotics given before cesarean delivery (3 grams of cefazolin) will reach adequate levels in adipose (fat cells underneath the skin) and serum (blood) samples. In addition, researchers hope to evaluate if/how the mother's weight has an effect on the levels of antibiotics in the tissues (a group of similar cells). This follow up study (prior study HS# 2009-7015 at UCI) will enroll obese (Body Mass Index (BMI) of 30-40) and morbidly obese (BMI \>40) women to receive an increased dose of prophylactic cefazolin at time of scheduled cesarean delivery at both UCI and LBMMC. Researchers hope to enroll a total of 35 women overall.

Interventions
Participants who are undergoing an elective cesarean section at term will receive 3 grams of Cefazolin at least 30, but no more than 60 minutes prior to skin incision administered through an intravenous line.
