The administration of dopamine using an in vivo animal model has been shown to prevent and treat diaphragm fatigue. ⋯ This study is the first to report the class and specific subtype of dopamine receptors found in the diaphragm. By identifying dopamine receptors in the diaphragm, we have a better understanding of the mechanisms by which dopamine treats and prevents diaphragm fatigue.

The advancements in surgical technique and perioperative care have significantly improved the survival of children with single ventricle (SV) congenital heart disease (CHD) over the past decade. The population who have undergone the Fontan operation are growing into adulthood and facing many unique challenges. Past research has focused on functional and neurodevelopmental outcomes with inferences made to health-related quality of life (HRQOL). ⋯ Questions still remain on how these patients will transition into adulthood and whether they will live normal productive lives. This article reviews the literature related to HRQOL in the SV subgroup of CHD. In addition, an overview of newly developed disease-specific HRQOL instruments is presented as well as limitations and future research in HRQOL of the SV Fontan population.

The research was designed to describe the care and communication processes during weaning from long-term mechanical ventilation (LTMV). A portion of those findings, specifically, how family members interact with the patient and respond to the ventilator and associated intensive care unit bedside equipment during LTMV weaning, are reported here. ⋯ Critical care clinicians influence families' acquisition of interpretive surveillance skills at the bedside of patients who are being weaned from LTMV. This study provides a potentially useful conceptual framework of family behaviors with long-term critically ill patients that could enhance the dialogue about family-centered care and guide future research on family presence in the intensive care unit.
