Two-drug Antibiotic Prophylaxis in Scheduled Cesarean Deliveries

September 15, 2019 updated by: Tali Wajsfeld, RWJ Barnabas Health at Jersey City Medical Center

Azithromycin-based Extended-spectrum Prophylaxis in Scheduled Cesarean Deliveries

Cesarean deliveries are the most common surgical procedure performed in the United States. A significant decrease in cesarean delivery associated maternal morbidity has been achieved with preoperative prophylactic single-dose cephalosporin, widely used before skin incision. Also, on laboring patients and/or with rupture of membranes, several studies suggest that adding azithromycin to standard cephalosporin prophylaxis is cost-effective and reduces overall rates of endometritis, wound infection, readmission, use of antibiotics and serious maternal events. Azithromycin has effective coverage against Ureaplasma, associated with increased rates of endometritis. Although two-drug regimen has been suggested for laboring and/or patients that undergo cesarean delivery, no studies have investigated the potential benefits of two-drug regimen in non-laboring patients.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Cesarean deliveries are the most common surgical procedure performed in the United States, and scheduled cesarean deliveries account for at least 40% of all cesarean deliveries every year. A significant decrease in cesarean delivery associated maternal morbidity has been achieved with preoperative prophylactic single-dose cephalosporin given within 60 minutes of skin incision. Also, on laboring patients and/or with rupture of membranes, several studies suggest that adding azithromycin to standard cephalosporin prophylaxis is not only cost-effective but reduces overall rates of endometritis and wound infection. Azithromycin provides effective coverage against Ureaplasma, commonly associated with increased rates of endometritis. Although two-drug regimen has been suggested for laboring and/or patients that undergo cesarean delivery, no studies have investigated the potential benefits of two-drug regimen in non-laboring patients. No increase in neonatal morbidity was noted with adjunctive azithromycin prophylaxis, including adverse events.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Rates of Endometritis
Time Frame: Up to 6 weeks after delivery
Presence of at least two of the following signs with no other recognized cause: fever (temperature of at least 38°C [100.4°F]), abdominal pain, uterine tenderness, or purulent drainage from the uterus.
Up to 6 weeks after delivery
Rates of Wound Infection
Time Frame: Up to 6 weeks after delivery
Presence of either superficial or deep incisional surgical-site infection characterized by cellulitis or erythema and induration around the incision or purulent discharge from the incision site with or without fever and included necrotizing fasciitis. Wound hematoma, seroma, abscess or breakdown alone in the absence of the preceding signs did not constitute infection.
