Intraperitoneal Carbon Dioxide Concentration Measurement During Standard Laparoscopy With a New Airseal Access Port

September 3, 2013 updated by: David Earle, Baystate Medical Center

SurgiQuest AirSeal CO2 Gas Quality

The new AirSeal access port for laparoscopic surgery does not use a mechanical valve on the port to maintain gas in the peritoneal cavity. It uses an invisible barrier created by high flow gas jets within the port. The percentage of carbon dioxide, the standard gas used for laparoscopy, during laparoscopic surgery has not been previously measured, but is probably high. The investigators aim to measure the percentage of intraperitoneal carbon dioxide with standard ports and the AirSeal port during a variety of conditions during laparoscopic procedures including suturing and suctioning. The study period will commence at the start of the operation, and be completed upon discharge from the hospital or postoperative day 5, whichever is shorter. All devices are approved for use in humans by the FDA, and are being used for their intended purpose.

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

The SurgiQuest AirSeal system is approved by the Food and Drug Administration (FDA) as access port for laparoscopic surgery that utilizes an invisible air curtain rather than a mechanical barrier to maintain pneumoperitoneum. In addition to the cannula, there is special filtration tubing and an air pump that act in concert with an existing CO2 insufflator. The system has been approved for use and purchase at Baystate Medical Center by the value analysis committee. Despite FDA approval and extensive laboratory testing, there is still no human data regarding intraperitoneal CO2 levels under a variety of conditions one would normally experience during a laparoscopic operation. The specific aim of this study is to measure these levels during laparoscopic cases in humans. We hypothesize that there will be no more than minimal alteration of intraperitoneal CO2 levels when using the AirSeal system when compared to the standard laparoscopic system. The follow-up to this is examining evidence of extraperitoneal gas extravasation. This will occur as part of routine post-operative care, but we will be collecting data, that will be de-identified in the post-operative period.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

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
percent of intraperitoneal carbon dioxide during surgery
Time Frame: intraoperative - starts at beginning of the operation and ends at the completion of the operation
intraperitoneal carbon dioxide measurements intraoperatively
intraoperative - starts at beginning of the operation and ends at the completion of the operation

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
Time Frame
subcutaneous emphysema
Time Frame: during the patients hospital stay, or the first 5 days postoperatively.
during the patients hospital stay, or the first 5 days postoperatively.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
October 1, 2011

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
