Review the literature to identify the most effective method of oral hygiene to reduce the incidence of ventilator-associated pneumonia (VAP). ⋯ No consensus on best practice for oral hygiene in patients being treated with mechanical ventilation was found. Chlorhexidine was the most popular oral care product. Implementation of an oral care protocol, ongoing nurse education, and evaluation were important in reducing the incidence of VAP. Future research should analyze chlorhexidine concentration, application techniques, and frequency of oral care, to optimize VAP prevention.

Patients with terminal brain stem herniation experience global physiological consequences and represent a challenging population in critical care practice as a result of multiple factors. The first factor is severe depression of consciousness, with resulting compromise in airway stability and lung ventilation. Second, with increasing severity of brain trauma, progressive brain edema, mass effect, herniation syndromes, and subsequent distortion/displacement of the brain stem follow. ⋯ In general, these multisystem consequences are managed with mechanism-based interventions within the context of caring for the donor's organs (liver, kidneys, heart, etc.) after death by neurological criteria. These processes begin far earlier in the continuum of injury, at the moment of terminal brain stem herniation. As such, aggressive, mechanism-based care, including hormonal replacement therapy, becomes clinically appropriate before formal brain death declaration to support cardiopulmonary stability following terminal brain stem herniation.
