Respiratory failure & ventilation
Comparison of tolerance of 4 interfaces for preventive non invasive ventilation after abdominal surgery in intensive care units assessed by patients and caregivers: A prospective randomized cross-over study
Authors' conclusion
The results suggest that none of the interfaces is universally better than the others, with no differences in comfort scores.
Study context
- Population
- Intensive Care Units (ICU) patients receiving preventive noninvasive ventilation (NIV) post-extubation after abdominal surgery
- Participants
- 26 consecutive patients
- Comparison
- 4 NIV interfaces: 2 full-face vs 2 oro-nasal
- Primary endpoint
- Tolerance (visual numeric scale 0–10: comfort, leaks, communication), auto-evaluation by patients and hetero-evaluation by caregivers
- Follow-up
- End of each NIV trial
Methodological detailsprospective, single-centre, Bonferroni correction (P<0.008 significant)
- Prospective
- Single-centre
- Bonferroni correction (P<0.008 significant)
Primary result
As reported in the abstract
Tolerance, auto-evaluation of comfort and leaks
- No significant difference between the interfaces for auto-evaluation of comfort and leaks

— not stated in the abstract
Hetero-evaluation of leaks
- No difference between the interfaces
Hetero-evaluation of communication
- Similar results to auto-evaluation
Caregiver vs patient evaluation
- Caregivers overestimated comfort and communication scores for each interface
- P < 0.008
- Except for Helmet
- P = 0.05
