Respiratory failure & ventilation
Dynamic inflation prevents and standardized lung recruitment reverts volume loss associated with percutaneous tracheostomy during volume control ventilation: results from a Neuro-ICU population
Authors' conclusion
Volume control ventilation did not prevent the PT-induced lung derecruitment. RM could restore the baseline lung volume and mechanics.
Study context
- Population
- Patients with acute brain injury undergoing percutaneous tracheostomy (PT) during volume control ventilation, Neuro-ICU
- Participants
- 25 patients
- Exposure
- Baseline vs after PT vs after standardized recruitment maneuver (RM)
- Outcome
- Crs and end-expiratory lung volume (EELV) (EELI by electrical impedance tomography (EIT) as surrogate) after PT and after RM
Methodological detailssingle center
- Single center
Main finding
Crs and EELI (surrogate of EELV)
Mean reduction in end-expiratory lung impedance (EELI)
432 arbitrary units
P = 0.049
By group
As reported in the abstract
Observational data: associations, not effects.
Further findings
Dynamic inflation (gradual progressive EELI increase) during PT (subgroup)
- Subgroup with gradual but progressive increase in EELI
- N = 8, 31%
- No decrease of Crs after PT vs patients without dynamic inflation
Safety
- Dynamic inflation did not cause hemodynamic impairment nor raised ICP
