  Purpose

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.

Primary Outcome Measures:
  • Achievement of minimal inhibitory concentrations within adipose and serum sampled at time of cesarean delivery [ Time Frame: Samples will be frozen and batched and run at completion of the study. Goal for sample collection to be complete over a 6-9 month time period with samples run as a batch within a month of sample collection completion. ] [ Designated as safety issue: No ]

    Primary Objective:

    To assess the effects of increased prophylactic doses of Cefazolin in the obese and morbidly obese populations undergoing cesarean delivery. Effects will be defined as the ability to reach the minimal inhibitory concentrations for gram-positive and gram-negative organisms in adipose tissue and serum at time of skin incision and skin closure as defined by the Clinical and Laboratory Standards Institute



Estimated Enrollment: 28
Study Start Date: August 2013
Estimated Study Completion Date: June 2015
Estimated Primary Completion Date: June 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Cefazolin
All subjects undergoing elective term cesarean delivery will receive 3 grams of Cefazolin at least 30, but no more than 60 minutes prior to skin incision.
Drug: Cefazolin
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.
