Department of Anesthesia, Montreal Children s Hospital, Montreal, Quebec, Canada
Can J Anaesth 51:62-7. 2004..To determine, in a subset of children previously reported, if the time of day when adenotonsillectomy for severe obstructive sleep apnea syndrome (OSAS) was performed affected the incidence of postoperative respiratory complications...
- Recurrent hypoxia in rats during development increases subsequent respiratory sensitivity to fentanylImmanuela Ravé Moss
Departments of Pediatrics and Physiology, McGill University, The Montreal Children s Hospital, 2300 Tupper Street, Montreal, Quebec H3H 1P3, Canada
Anesthesiology 105:715-8. 2006..The authors hypothesize that this association is due to an effect of recurrent hypoxemia that accompanies more severe obstructive sleep apnea on altered responsiveness to subsequent exogenous opiates...
