Review Meta Analysis
Effectiveness of Intraoral Chlorhexidine Protocols in the Prevention of Ventilator-Associated Pneumonia: Meta-Analysis and Systematic Review.
Ventilator-associated pneumonia (VAP) is common in critical patients and related with increased morbidity and mortality. We conducted a systematic review and meta-analysis, with intention-to-treat analysis, of randomized controlled clinical trials that assessed the effectiveness of different intraoral chlorhexidine protocols for the prevention of VAP. ⋯ We found that oral care with chlorhexidine is effective in reducing VAP incidence in the adult population if administered at 2% concentration or 4 times/d.

Obstructive fibrinous tracheal pseudomembrane (OFTP) is an uncommon complication that results after tracheal intubation. Herein, we perform a systematic review of the PubMed and EmBase databases for all the cases describing OFTP. The systematic search yielded 28 citations describing 53 subjects with OFTP. ⋯ OFTP is a complication of tracheal intubation and presents with respiratory failure. The diagnosis can be confirmed by flexible bronchoscopy. Treatment involves removal of the obstructing membrane with either flexible or rigid bronchoscopy.

Brain Tissue Oxygen Monitoring and the Intersection of Brain and Lung: A Comprehensive Review.
Traumatic brain injury is a problem that affects millions of Americans yearly and for which there is no definitive treatment that improves outcome. Continuous brain tissue oxygen (PbtO2 ) monitoring is a complement to traditional brain monitoring techniques, such as intracranial pressure and cerebral perfusion pressure. PbtO2 monitoring has not yet become a clinical standard of care, due to several unresolved questions. ⋯ Thus, continuous monitoring of PbtO2 yields important information about both the brain and the lung. The preclinical and clinical studies demonstrating these findings are discussed. In this review, we demonstrate that patient management in a PbtO2 -directed fashion is not the sole answer to the problem of treating traumatic brain injury but is an important adjunct to the armamentarium of multimodal neuromonitoring.
