Factor VIII preservation following collection into commercial plasmapheresis systems.

The two-stage method of Pool and Robinson was used in determining plasma Factor VIII activity following contact with four commercially available plastic blood and pooling bag films. Employing a two-arm double plasmapheresis technique, it was shown that Factor VIII activity in whole blood initially drawn into BB-69 and PL-130 blood bags decreased only slightly from in vivo levels for activity in PL-130 blood bags (t equal 3.2317, p. less than 0.01). Factor VIII activity fell to 98 and 90 per cent preservation levels from an initial 104 per cent in vivo activity, for BB-69 and PL-130 respectively. Factor VIII activity in plasma collected in Ellay and PL-146 pooling bags, both decreased significantly to 85 and 86 per cent, respectively, after three hours storage at room temperature (24 to 25.5 C). Following five weeks storage (-30 C) in Ellay and PL-146 pooling bags, Factor VIII activity significantly (p less than 0.005) fell to 79 and 77 per cent, respectively. No significant differences were observed when Factor VIII activity levels were compared in BB-69 versus PL-130 or Ellay versus PL-146 plastic film systems.

The dying patient: a comparative study of nurse caregiver characteristics.

The nurse's interaction with the dying patient is thought to be influenced by death anxiety, attitudes toward death, and perceptions of control. Differences relative to these three variables between nurses who work on a continuous basis with the dying and those who rarely encounter a dying patient were examined. Using 3 paper and pencil questionnaires, data were collected from 105 nurses (32 palliative care nurses, 44 psychiatric nurses, 29 orthopedic nurses). Significant differences were found between the palliative care nurses and nonpalliative care nurses on attitudes toward death and on 3 of the 4 subscales that assessed death anxiety. Suggestions for future research include a systematic examination of the relationship of attitudes and feelings about death to patient care.

Placing blood on the target: a challenge for visually impaired persons.

An individualized, blood glucose self-monitoring procedure for those who are visually impaired must be developed, taught, practiced, observed, and reviewed. Effective teaching requires understanding functional vision loss, observing safety precautions, organizing the work area, obtaining an adequate blood sample, ensuring accurate placement of blood on the strip, and cleaning up. Thoroughness and repetition enable the visually impaired person to perform the procedure safely and confidently.
