In this study we explored the relationship between critical care family members' perceived needs and the assessment of these needs by a confederate sample of intensive care unit (ICU) nurses. Family needs were measured by using Molter's revised Critical Care Family Needs Inventory. Data consisted of 92 confederate pairs of Critical Care Family Needs Inventory responses obtained from 92 family members of adult patients hospitalized in a variety of ICUs and 49 ICU nurses providing direct care for these patients. ⋯ Significant (p less than 0.001 to p less than 0.05) differences were detected between confederate pairs of family members' perceptions and ICU nurses' assessments of the importance of 15 (50%) of the critical care family needs studied. Therefore, it appears that these nurses were only moderately accurate in their assessments of critical care family needs. Implications for nursing practice, education, and research were identified and discussed.

[Tissue oxygenation during recovery from anesthesia. Value and measurement].
The measurement of tissue oxygen concentrations in the intensive care unit is important for the management of patients, especially those in shock. In daily practice, right heart catheterization with continuous monitoring of the oxygen saturation of mixed venous blood provided means of evaluating the principal parameters of oxygenation (transport, consumption and extraction), and of analyzing therapeutic interventions. The finding of an oxygen debt implies an appropriate therapeutic response designed to balance oxygen supplies with peripheral oxygen demand.

In patients with multiple injuries, the development of permeability edema can be assumed. However, no uniform shape of this fluid accumulation can be found even in the presence of severe injuries. Based on the first clinical observations, our aim was to search for correlations between the development of extravascular lung water (EVLW) and the individual injury pattern in severely traumatized ICU patients. ⋯ Increase of EVLW at a later time (day 7), as observed in groups B and C, is possibly the expression of a mediator and activator-induced "septiformal" injury of the microvascular endothelium. This may be caused by the underlying massive peripheral soft-tissue trauma. Specific elevations of EVLW subsequent to the individual injury pattern can indicate that that process has begun and is responsible for the origin of the microvascular injuries.

Trauma is the leading cause of death in young Americans and is responsible for the loss of more productive years of life than heart disease and cancer combined. Initial management of trauma consists of the establishment or maintenance of a patent airway, ensurance of adequate breathing, and resuscitation of the circulation. All of these are accomplished simultaneously with a cursory survey to identify immediately life-threatening injuries and to prevent permanent disability.
