BACKGROUND: The needs and satisfaction levels of family members of critically ill patients have received much attention in the literature. The feelings of family members, however, have not been thoroughly investigated. To develop appropriate nursing interventions to assist family members in coping with a critical care hospitalization, accurate information about their emotional response to the situation is needed. OBJECTIVE: To examine emotional responses of family members and their descriptions of supportive behaviors of others during a critical care hospitalization. METHODS: An exploratory design was used to study 52 subjects with critically ill family members in the pediatric, neonatal, medical, surgical and cardiovascular intensive care units in a large tertiary care hospital. The subjects kept daily logs of their feelings and the supportive behaviors of others. Thematic analysis was used to identify major themes. RESULTS: Analysis revealed a broad range of powerful emotions throughout the intensive care unit stay. Negative and positive emotions such as despair and joy were sometimes identified by subjects within a 24-hour period. Although fear, worry, anger and exhaustion were dominant themes during the first 24 hours and when the family received bad news about the patient, there was no pattern of emotional response evident as the stay progressed. Some differences between subjects drawn from the medical and neonatal intensive care units were evident. CONCLUSIONS: The findings suggest that family members of critically ill patients experience deep emotional turmoil throughout the intensive care unit stay. Specific nursing interventions to promote adaptive coping are needed throughout the experience.

How much blood must be discarded from a heparinized arterial line to obtain accurate coagulation studies, specifically activated partial thromboplastin time? The published literature provides insight into the question and guidelines for practice in adult critical care. This article reviews and integrates findings from 14 research studies published from 1971 to 1993 on discarding blood from arterial lines for coagulation studies. Investigators compared activated partial thromboplastin time values from arterial and venous blood samples using various discard volumes, sites and sizes of catheters, and heparin flush concentrations. Similarities and differences in arterial and venous activated partial thromboplastin time were reported. Studies have demonstrated that adequate discard volume for activated partial thromboplastin time is 6 times the catheter dead space. These results should not be generalized to systemically heparinized patients, pediatric patients, or other types of heparinized lines such as pulmonary artery, central venous, or Hickman catheters.

The American Association of Critical-Care Nurses completed a three-phased process of priority identification for critical care nursing research. In phase 1, a 78-item survey was generated following a comprehensive review of potential research topics. In phase 2, approximately 1000 critical care nurses rated each item on the survey for importance to critical care nursing. Based on these results, the AACN Research Committee formulated a clinical and a nonclinical (contextual) list of research topics. Each list contained 25 topics. In phase 3, topics were given final rankings at a 1-day Consensus Conference on Research Priorities. Both Likert-type and magnitude estimation scaling were used to determine priority ranking of items on each list. As a result, both clinical and contextual research priorities were established for AACN.
