Study summary

The sole objective in this study is to evaluate if routine amounts of opioids given for tonsillectomy in children have greater amounts of respiratory depression in children with documented obstructive sleep apnea when compared with patients that do not have obstructive sleep apnea

Read the detailed description

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 adults 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. It is well known that OSA in children is significantly different from OSA in adults (e.g. gender predilection, central vs. peripheral causation). The manifestation and etiologies are very different in pediatric OSA making it a vastly different disease process.

What researchers measure

Primary outcomes

  1. Respiratory Depression Following Opioids

    Identification of respiratory depression following routine fentanyl administration by recording the respiratory rate prior to and 10 minutes following fentanyl administration

    Time frame: Mean respiratory rate % change from baseline measured 10 minutes following opioid administration

  2. Respiratory Depression Following Opioids

    Identification of respiratory depression following routine fentanyl administration by recording the tidal volume % change from baseline prior to and 10 minutes following fentanyl administration

    Time frame: mean percentage of change from baseline in tidal volume measured 10 minutes following opioid administration

  3. Respiratory Depression Following Opioids

    Identification of respiratory depression following routine fentanyl administration by recording the end-tidal co2 % change from baseline prior to and 10 minutes following fentanyl administration

    Time frame: mean percentage of change from baseline in end tidal co2 measured 10 minutes following opioid administration
