Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Children with Down syndrome (DS) often experience dangerously low heart rates on induction of anesthesia for routine procedures and this occurs at 10 times the rate of non-DS patients. Given that the cardiac output of children is heart rate dependent, bradycardia is especially perilous in this population.

Historically, individuals with DS were not expected to survive beyond childhood; consequently, correction of congenital anomalies, e.g. cardiac defects, was not frequently offered. Fortunately, today individuals with DS live into adulthood and surgical correction of anomalies is universally offered. Thus, increasing numbers of children with DS are exposed to anesthesia and at risk for this hemodynamic catastrophe. It is medically unacceptable and an autonomic nervous system mechanism will be sought.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Down Syndrome patients undergoing otolaryngologic surgery with anesthesia

Monitoring patients undergoing surgery to look for association between ANS activity and bradycardia

Intervention Type OTHER

Use of an Ambulatory Monitoring System from Vuije University (VU-AMS) to record autonomic and cardiovascular activity of patients undergoing otolaryngologic surgery with anesthesia. This monitoring device will provide data of ANS activity and normoxic bradycardia among patients with Down Syndrome. This data will be compared to data from patients without Down Syndrome.

Non-Down Syndrome patients undergoing otolaryngologic surgery with anesthesia

Monitoring patients undergoing surgery to look for association between ANS activity and bradycardia

Intervention Type OTHER

Use of an Ambulatory Monitoring System from Vuije University (VU-AMS) to record autonomic and cardiovascular activity of patients undergoing otolaryngologic surgery with anesthesia. This monitoring device will provide data of ANS activity and normoxic bradycardia among patients with Down Syndrome. This data will be compared to data from patients without Down Syndrome.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Patients who are overtly healthy as determined by medical evaluation including lack of diagnosis of Down Syndrome and children with Down Syndrome

Exclusion Criteria

1. Contraindication to adhesive placement, eg, epidermolysis bullosa
2. Patient or parent refusal
3. Opioids
4. Heart rate altering therapy such as beta blockers
5. During the study period, participants will abstain from ingesting caffeine- or xanthine-containing products (eg, coffee, tea, cola drinks, and chocolate) for \[6 hours\] before the start of the anesthetic.
6. Participants will be assumed not to be using tobacco or alcohol during the study period due to their young age.
