To determine fluctuation in mixed venous oxygen saturation in critically ill medical patients during a period of rest. ⋯ Knowledge of normal fluctuation enables the care giver to evaluate changes in mixed venous oxygen saturation in response to activities and/or treatments. Additional study of fluctuation in homogenous groups of critically ill patients is warranted.

To explore the relationships between parents' reactions to the pediatric intensive care unit admission of a child and characteristics of the child's illness. ⋯ Parents' reactions to their child's critical illness and admission to the pediatric intensive care unit were not related to characteristics of the child's condition in this small sample. Future research needs are suggested.

To help the clinician bridge the gap between research and practice in determining ways to minimize side effects of endotracheal suctioning. ⋯ An algorithm to guide clinical decision making is presented based on the conclusions of this review of the research.

Comparative Study Clinical Trial
Comparison of PT and aPTT values drawn by venipuncture and arterial line using three discard volumes.
Blood samples obtained through heparinized arterial catheters are used routinely for a variety of laboratory tests. Accuracy of coagulation studies performed from samples obtained in this fashion continues to be questioned, particularly in regard to the minimum discard volume necessary to clear the catheter of heparinized solution. ⋯ We recommend that when drawing prothrombin time and activated partial thromboplastin time samples from an arterial line, a 5.3-mL discard volume be used.

To evaluate the effectiveness of two methods of meeting the information needs of families of critically ill patients: an open visiting hour policy and a family information booklet. ⋯ Flexible visiting hours and information booklets were two practical methods of meeting the information needs of families. Open visiting hours, as a singular intervention, significantly improved family satisfaction. The effectiveness of the booklet in assisting families to recall discrete pieces of information supports the further development and use of preprinted materials to assist in meeting family information needs.
