Respiratory events after adenotonsillectomy in children with severe obstructive sleep apnea (OSA): A prospective exploratory study
Authors' conclusion
This exploratory study suggests that PACU low MV events may predict subsequent events on the ward in children with severe OSA undergoing adenotonsillectomy.
Study context
- Population
- Children <18 years with severe OSA undergoing adenotonsillectomy with planned postoperative admission
- Participants
- 60 children
- Outcome
- Low MV events on the ward (predicted MV < 40% for at least 2 min), measured by noninvasive respiratory volume monitor (RVM)
- Follow-up
- First postoperative night
Main finding
As reported in the abstract
Low MV events on the ward
Low minute ventilation (MV) events on the ward (34/55)
62%
Observational data: associations, not effects.
