Brief Summary

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

Children OSA exhibit varying responses to opioids. It is unknown if the degree of intermittent hypoxemia results in different opioid sensitivity

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Ventilatory suppression in children following opioid administration is of obvious concern, especially following routine surgical procedures (i.e. adenotonsillectomy). It is thought that patients with obstructive sleep apnea (OSA) have increased sensitivity to opioids, and especially in opioid naïve patients. Recent evidence in children suggests that patients with moderate to severe OSA may not predispose patients to increased opioid sensitivity in the form of respiratory depression when compared with patients that do not have OSA. However, what is not known is wether the degree of hypoxemia experienced by patients effects the opioid sensitivity. The aim of this study is to identify if children with known OSA experience a difference in opioid induced respiratory depression based on the degree of hypoxemia.
