Trial summary

Traditionally cardiac output has been estimated with thermodilution. Recently a new non-invasive device has been approved by the FDA for use in children of all ages including neonates (just 4 EKG electrodes). Read more about this study

About this study

Traditionally cardiac output has been estimated with thermodilution. Recently a new non-invasive device has been approved by the FDA for use in children of all ages including neonates (just 4 EKG electrodes). Primary outcome: To prospectively collect simultaneous physiologic data for all enrolled children by transferring the data from the investigators computerized anesthesia records to Excel spreadsheets and to correlate adverse events across monitoring devices.

Secondary outcomes: To determine if the device provides meaningful data in terms of an early warning of decreased cardiac output in specific subgroups of children undergoing surgery and anesthesia, e.g., neonates, trauma patients, children with congenital heart disease, those undergoing procedures with expected blood loss, those undergoing laparoscopic procedures where gas insufflation may impede venous return to the heart.

Read the detailed description

All children undergoing both elective and emergent surgery or GI endoscopy evaluation will be candidates for study. Since this is an FDA approved monitor that is approved across all age groups and since this is an additional monitor over those routinely used in the operating room and since it is noninvasive (4 EKG leads) verbal consent documented in the record has been approved by the IRB.

After informed verbal consent, either the research coordinator or a study physician will populate the cardiac output device with the child's age, weight, gender and height. For older children the required 4 EKG electrodes will be applied prior to induction of anesthesia (2 on the left side of the neck and 2 on the left chest at the level of the sternal depression; for neonates and infants one electrode can be applied to the forehead and the other to a thigh if application space is a problem). For children who are not able to be cooperative, as with most of our monitors the electrodes will be placed after induction of general anesthesia. An automated anesthesia record will continuously record heart rate, respiratory rate, oxygen saturation, systolic and diastolic pressures. The monitor will be set to perform these measurements every 1 minute. New software has been written that enables us to interface the cardiac output device with our automated anesthesia record. Thus the data from the cardiac output device will be inserted on the anesthesia record at approximate 1 minute intervals in real time. The data from the anesthesia records will later be downloaded as a unit to Excel spread sheets for later analysis. All demographic data will also be downloaded (age, weight, ASA physical status,surgical procedure) as well as blood loss and blood and fluid administered as well as drugs,significant intraoperative events, and the timing of events as they evolve. All data will be entered on a Partners password protected computer. Initially the patient's medical record number which links us to the electronic anesthesia record will be recorded as this allows us to download the data. Patient names will not be downloaded. Once the data set is completed,analyzed and locked, the medical record number will be removed so that no identifiers will remain. The data will not be shared with any other institution. Only deidentified data will remain on the final data base

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Correlate adverse cardiovascular events in children under anesthesia with the cardiac output device and standard anesthesia monitors

    We plan to record all physiologic data from approximately 400 children under anesthesia and correlate adverse cardiovascular events determined by this new cardiac output device with standard anesthesia monitors

    Measured: approximately 18 months

Secondary outcomes (1)
  1. determine if this device provides additonal safety for specific subgroups of pediatric patients under anesthesia e.g., those undergoing laparosopic procedures or procedures involving significant blood loss, neonates

    determine is some subgroups within the proposed 400 cases derive specific benefit from this additional non-invasive monitor, i.e., an early warning of impaired cardiac output or a correlation with decreased blood pressure with decreased cardiac output. The issue is whether cardiac out updated at approximate 20 second intervals can provide an eralier warning than the standard 3 to 5 minute blood pressures provided by non-invasive blood pressure monitroing which is the standard of care.

    Measured: approximatley 18 months

Questions about this trial

What is this clinical trial studying?

An observational study of Children Receiving General Anesthesia, run by Massachusetts General Hospital at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Apr 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Correlate adverse cardiovascular events in children under anesthesia with the cardiac output device and standard anesthesia monitors (time frame: approximately 18 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01499615, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Apr 2015.
