Investigating the Safety of Post-surgical Analgesics in Children With Obstructive Sleep Apnea
Every year thousands of young children with obstructive sleep apnea undergo surgery which requires them to be prescribed pain medication. The current standard in North America is administration of opioids, mainly codeine or morphine; however in many areas of the world including Canada, nonsteroidal anti-inflammatory medications such as ibuprofen are used. Some North American surgeons are uncertain regarding the potential of ibuprofen to increase bleeding following surgery. The results of research studies have been inconclusive overall. Due to recent codeine fatalities in children following adenotonsillectomy, codeine has been removed from the formulary at many Pediatric institutions. Some surgeons have begun to use oral morphine as an alternate to codeine, which necessitates the need to find safe alternative analgesics in this treatment group.
The primary objectives of this study is to assess the safety(1) and efficacy (2) of morphine and ibuprofen in children with sleep apnea.
An interim analysis will be conducted after recruitment of 70 patients, to monitor both safety and efficacy
Pediatric Obstructive Sleep Apnea Syndrome
|Study Design:||Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Investigating the Safety of Morphine and Ibuprofen in Children Post-adenotonsillectomy for Obstructive Sleep Apnea|
- Safety [ Time Frame: 1.5 years ] [ Designated as safety issue: No ]Safety will be assessed by comparing changes in respiratory parameters (oxygen saturation and the number of apnea events per night) following adenotonsillectomy.
- Effectiveness [ Time Frame: 1.5 years ] [ Designated as safety issue: No ]Analgesic effectiveness between treatment groups will be assessed using the visual analog scale and the objective pain scale
- Risk Factors [ Time Frame: 1.5 years ] [ Designated as safety issue: No ]Age, BMI, OSA severity and genetic factors will be compared between treatment groups. Furthermore, these factors will be isolated to determine any correlation exists with respiratory parameter improvement in all enrolled patients.
