January 1, 2015 updated by: Osvaldo A. Reyes T., Saint Thomas Hospital, Panama

Supplemental Perioperative Oxygen at 80% FIO2 to Reduce the Incidence of Post-cesarean Wound Infection. A Randomised, Clinical Trial

The purpose of this study is to determine if the use of supplemental oxygen at 80% FIO2 can reduce the incidence of surgical site infection after emergency cesarean section.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Surgical site infection (SSI) is one of the most important complications that can develop after a cesarean section. SSI can be mild or it can develop into septic shock and death, being cesarean section the most important cause of puerperal infections. Supplemental oxygen at high doses has been advocated as a protective factor for SSI. The purpose of this study is to determine if the use of oxygen at high doses (80% FIO2)can reduce the incidence of SSI after emergency cesarean section.

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.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Oxygen 80% FIO2
Group of 181 patients that will receive supplemental oxygen 80% FIO2 during surgery (cesarean) and two hours after the procedure.
Device: Supplemental oxygen 80% FIO2
Use of oxygen 80% FIO2 during surgery and 2 hours after the procedure. For this purpose an oxygen mask with reservoir will be used (to guarantee the supply of 80% oxygen during and after surgery)
Other Names:
  • High dose oxygen
Placebo Comparator: Use of air (no oxygen during surgery)
Group of 181 patients that will not receive supplemental oxygen during surgery (cesarean).
Procedure: Use of air (no oxygen during surgery)
No use of oxygen during surgery or in the 2 hours after the procedure.
Other Names:
  • No oxygen

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
Number of participants with surgical site infection (SSI).
Time Frame: 2 months
The patients will be evaluated for evidence of surgical site infection before leaving the hospital, at 15 and 30 days post surgery. The presence of fever, supurative secretion through the wound or cutaneous changes compatible witn infection will be considered a surgical site infection (SSI). This outcome will be evaluated with a qualitative variable (presence of SSI). The patients will be clasiffied in accordance as "With SSI" or "Without SSI". This will allow us to determine if the use of oxygen at 80% FIO2 can reduce the incidence of SSI.
2 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of participants with respiratory complications trans or post surgery.
Time Frame: 2 months
Every patient will be evaluated during surgery and before leaving the hospital for signs of a respiratory complication (persistent cough, fever, dyspnea, atelectatic rales, wheezing). The presence of any of these signs will be used to classify the patients with a qualitative variable ("With Respiratory Complications" or "Without Respiratory Complications") and allow us to determine if the use of oxygen at 80% FIO2 is associated with more respiratory complications.
