Evaluation of the i‐gel® Plus supraglottic airway device in elective surgery: a prospective international multicentre study*
Authors' conclusion
The i-gel Plus appears to be an effective supraglottic airway device that is associated with a high insertion success rate and a reasonably low incidence of complications.
Study context
- Population
- Adults undergoing elective procedures under GA1,000 included
- Participants
- 1,012 adults
- Outcome
- Overall insertion success rate (effective airway management through the device from insertion until end of surgery)
Methodological detailsinternational, multicentre
- International
- Multicentre
Main finding
As reported in the abstract
Overall insertion success rate
Overall insertion success rate
98.6%
Observational data: associations, not effects.
Secondary outcomes
Overall success rate by sex (subgroup)
First-attempt insertion success rate
- First-attempt success rate of insertion
- 88.2%
Overall success rate by sex (subgroup)
- Significant difference between females and males for overall success, not for first-attempt success
Oropharyngeal seal pressure
- Mean (SD) oropharyngeal seal pressure
- 32 (7) cmH2O
Risk factors for first-attempt failure
- Low operator experience was the only independent factor increasing risk of first-attempt failure
Safety
Complications
- Desaturation < 85%
- 0.6%
- Traces of blood on the device
- 7.4%
- Laryngospasm
- 0.5%
- Gastric contents inside the bowl
- 0.2%
