Effect of paratracheal pressure on the effectiveness of mask ventilation in obese anesthetized patients: a randomized, cross-over study
Authors' conclusion
The application of paratracheal pressure significantly increased both the expiratory tidal volume and peak inspiratory pressure during face-mask ventilation with a volume-controlled mode in obese anesthetized paralyzed patients.
Study context
- Population
- Obese anesthetized paralyzed patients, two-handed volume-controlled mask ventilation (tidal volume 8 mL kg-1 ideal body weight (IBW), 12 breaths min- 1, PEEP 10 cmH2O)
- Participants
- 48 participants
- Comparison
- Two-handed mask ventilation with vs without 30 N paratracheal pressure
- Primary endpoint
- Expiratory tidal volume during mask ventilation
Methodological detailscross-over, Gastric insufflation not evaluated
- Cross-over
- Gastric insufflation not evaluated
Primary result
As reported in the abstract
Expiratory tidal volume
P < 0.001
Further findings
Peak inspiratory pressure · significantly higher with paratracheal pressure
P < 0.001
Association of patient characteristics with effectiveness of paratracheal pressure
- No significant association
Safety
Hypoxaemia during mask ventilation
- Hypoxemia did not occur in any patient, with or without paratracheal pressure
