Meta AnalysisEffectiveness of Adaptive Support Ventilation in Facilitating Weaning from Mechanical Ventilation in Postoperative Patients.
This meta-analysis aims to evaluate the effectiveness of adaptive support ventilation (ASV) in facilitating postoperative weaning from mechanical ventilation in cardiac surgery patients. ⋯ ASV appears to facilitate a shorter time to extubation in postoperative cardiac surgery patients compared to conventional ventilation, suggesting benefits in accelerating the weaning process and reducing mechanical ventilation duration.

Controlled Clinical Trial
Non-invasive electromagnetic phrenic nerve stimulation in critically ill patients - a feasibility study.
Electromagnetic stimulation of the phrenic nerve induces diaphragm contractions, but no coils for clinical use have been available. We recently demonstrated the feasibility of ventilation using bilateral transcutaneous noninvasive electromagnetic phrenic nerve stimulation (NEPNS) before surgery in lung-healthy patients with healthy weight in a dose-dependent manner. ⋯ Bilateral transcutaneous NEPNS was feasible in the ICU setting with the potential benefit of preventing diaphragm atrophy during mechanical ventilation. NEPNS ventilation effectiveness needs further assessment.

Tracheal Intubation and Mechanical Ventilation in Adults with Severe Salicylate Poisoning.
Salicylate poisoning may lead to critical acid-base disturbances. Tracheal intubation and mechanical ventilation for patients with severe salicylism has been strongly discouraged. ⋯ In our single-center experience managing adults with severe salicylate poisoning, tracheal intubation and mechanical ventilation were not associated with substantial perturbation of serum pH or severe complications. These findings challenge the current paradigm that these interventions should be avoided in salicylate-poisoned patients.

Observational Study
Gastric pressure monitoring unveils abnormal patient-ventilator interaction related to active expiration: a retrospective observational study.
Patient-ventilator dyssynchrony is frequently observed during assisted mechanical ventilation. However, the effects of expiratory muscle contraction on patient-ventilator interaction are underexplored. The authors hypothesized that active expiration would affect patient-ventilator interaction and they tested their hypothesis in a mixed cohort of invasively ventilated patients with spontaneous breathing activity. ⋯ Active expiration can impair patient-ventilator interaction in critically ill patients. Without documenting gastric pressure, abnormal patient-ventilator interaction associated with expiratory muscle contraction may be mistakenly attributed to a mismatch between the patient's inspiratory effort and mechanical inflation. This misinterpretation could potentially influence decisions regarding clinical management.
