Observational StudyInter-Rater Reliability of Delirium Screening of Infants in the Cardiac ICU: A Prospective, Observational Study.
To determine the inter-rater reliability (IRR) of the Cornell Assessment for Pediatric Delirium (CAP-D) in infants admitted to a cardiac ICU (CVICU) and to explore the impact of younger age and mechanical ventilation on IRR. ⋯ In the youngest, most vulnerable infants admitted to the CVICU, further evaluation of the CAP-D tool is needed.

Reverse Triggering During Controlled Ventilation: From Physiology to Clinical Management.
Reverse triggering dyssynchrony is a frequent phenomenon recently recognized in sedated critically ill patients under controlled ventilation. It occurs in at least 30-55% of these patients and often occurs in the transition from fully passive to assisted mechanical ventilation. During reverse triggering, patient inspiratory efforts start after the passive insufflation by mechanical breaths. ⋯ On the basis of physiological data, reverse triggering might be beneficial or injurious for the diaphragm and the lung, depending on the magnitude of the inspiratory effort. Reverse triggering can cause breath-stacking and loss of protective lung ventilation when triggering a second cycle. Little is known about how to manage patients with reverse triggering; however, available evidence can guide management on the basis of physiological principles.

Pediatric extubation failure is associated with morbidity and mortality. The most common cause is upper-airway obstruction. Subglottic edema is common, but upper-airway obstruction can occur from the oral cavity to the trachea. Dichotomous categorization of extubation failure as airway versus non-airway may help identify risk factors as well as strategies that translate to lower extubation failure rates. ⋯ Airway extubation failure prevalence was 1.5 times higher than non-airway failure. Potential risk factors for airway failure were identified. These findings are hypothesis generating for future study focused on key evidence gaps and pragmatic bedside application.

To evaluate whether intraoperative ventilation using lower driving pressure decreases the risk of nonhome discharge. ⋯ Intraoperative ventilation maintaining lower driving pressure was associated with a lower risk of nonhome discharge, which can be partially explained by lowered rates of postoperative respiratory failure. Future randomized controlled trials should target driving pressure as a potential intervention to decrease nonhome discharge.

A 37-year-old man attended a medical clinic at the confluence of the Appalachian and the St. Lawrence Valley after 2 weeks of coughing greenish sputum and progressive dyspnea on exertion. In addition, he reported fatigue, fevers, and chills. ⋯ He returned to the emergency room 1 week later with mild hypoxemia, persisting fever, and a chest radiography consistent with lobar pneumonia. The patient was admitted to his local community hospital, and broad-spectrum antibiotics were added to the regimen. Unfortunately, his condition deteriorated over the following week, and he experienced hypoxic respiratory failure for which he required mechanical ventilation before his transfer to our medical center.
