To develop a conceptual path model to explain the effects of a set of personal and work-related independent variables and the dependent variables of situational stress, job stress and job motivation on job satisfaction among critical care nurses. ⋯ Thirteen variables had a significant effect on job satisfaction and explained 63% of the variance. The four most significant effects on job satisfaction were opportunities for advancement, meaningfulness of work, pay and supervision. Commitment to the career, task identity and job security had a modest effect on job satisfaction.

To describe the characteristics and service utilization patterns of long-term ventilator-dependent patients. ⋯ Additional studies are necessary to describe the prevalence, etiology, health status and functional status of ventilator patients at all levels of care; the impact of different system approaches on patient well-being and cost of care; and the process of medical decision making. Economic analyses of costs and outcomes for ventilator-dependent patients using a cost-utility approach are also needed.

Clinical Trial
Effects of a closed tracheal suction system on ventilatory and cardiovascular parameters.
To determine whether patients ventilated in the assist-control mode experienced a change in oxygenation, respiratory rate, inspiratory:expiratory ratio, heart rate, blood pressure or acid-base balance when suctioned with a closed tracheal suction system. ⋯ Subjects ventilated in the assist-control mode and suctioned with a closed tracheal suction system did not experience significant changes in cardiovascular or acid-base parameters when suctioned without hyperoxygenation. Although most subjects did not become desaturated, four subjects experienced desaturation at one or more intervals. To prevent desaturation, hyperoxygenation should be used before and after suctioning with a closed tracheal suction system.

Decisions to withdraw life-sustaining therapy are being made more often as patients and healthcare providers increase their awareness of patient rights. The process of withdrawal of mechanical ventilation must be conducted in a humane fashion. An understanding of the ethical, legal and practical considerations for patient management during this type of intervention will enhance the ability of the healthcare provider to participate.

To investigate the relationship of locus of control, parental age, and state anxiety to parental coping and activities performed during hospitalization of a child in a pediatric critical care center. ⋯ Appropriate strategies to bolster coping and reduce stress of parents need to be constantly reassessed because coping mechanisms vary according to parental age, locus of control, anxiety level, and parental involvement in child-care activities. More research is needed in the changes of parental coping mechanisms with time and child-care activity, to assess the benefits of interventions planned to encourage a problem-focused approach.
