January 10, 2020 updated by: Sherif Mohamed Abd el moneim Soaida, MD, Cairo University

Electrical Velocimetry (ICON Cardiometry) Assessment of Hemodynamic Changes With Different Inflation Pressures During Pediatric Thoracoscopic Surgery: A Pilot Study

Advances in endoscopic equipment and technique have led to the use of minimally invasive thoracic surgery in an increasing number of pediatric surgical procedures. Logically, thoracoscopic surgery and anesthesia can induce significant physiologic changes,, derangements of normal respiratory physiology induced by the surgical approach and the installation of carbon dioxide into the thoracic cavity can lead to alterations of normal acid-base status. Finally, surgical procedures in the chest, surgical traction or insufflation pressures impairs venous return and/or cardiac function, especially in neonates and infants. In this study Electrical Cardiometry TM (ICON, Cardiotronic/Osypka Medical, Inc., La Jolla CA, USA) is used assess the effect of different intra-thoracic pressure (insufflation pressures 4,5 & 6 mmHg) during thoracoscopic surgeries in neonates and infants on hemodynamics using electrical velocimetry (ICON) as non-invasive monitoring technique.

Study Overview

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.

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
change in Cardiac index
Time Frame: measured before inflation, 1 minute after inflation of the thoracic cavity at 4 mm Hg, 5 mm Hg and 6 mm Hg and after deflation
L/min/m2
measured before inflation, 1 minute after inflation of the thoracic cavity at 4 mm Hg, 5 mm Hg and 6 mm Hg and after deflation

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
non invasive blood pressure
Time Frame: from time of induction of anesthesia and every 5 minutes and after every change in intrathoracic pressure and after deflation till end of surgery
mmHg
