Transcutaneous carbon dioxide monitoring in children undergoing rigid bronchoscopy: a prospective blinded observational study
Authors' conclusion
Hypercapnia was a frequent event in children undergoing rigid bronchoscopy and severe hypercapnia was associated with a long PACU stay.
Study context
- Population
- Patients aged < 18 yr scheduled for rigid bronchoscopy
- Participants
- 30 patients
- Outcome
- Incidence of hypercapnia (TcCO2 > 50 mm Hg) in the OR
Methodological detailsblinded, OR team blinded to TcCO2; TcCO2 recorded from anesthesia induction to postanesthesia care unit (PACU) stay
- Blinded
- OR team blinded to TcCO2; TcCO2 recorded from anesthesia induction to PACU stay
Main finding
As reported in the abstract
Hypercapnia (TcCO2 > 50 mm Hg) in the OR
Incidence of hypercapnia in the OR
100%
Observational data: associations, not effects.
Further findings
Hypercapnia in the PACU
- Incidence of hypercapnia in the PACU
- 60%
Severe hypercapnia (TcCO2 > 90 mm Hg) in the OR
- Cases with severe hypercapnia in the OR
- 5 (17%)
Highest TcCO2
- Highest median [IQR] TcCO2, mm Hg
- 69 [61-79]
PACU stay and severe hypercapnia
- Patients with severe hypercapnia had long stays in the PACU
Safety
Perioperative adverse events
- Most common adverse event: oxygen desaturation
- 57%, 17/30
