AANA Journal course: new technologies in anesthesia: update for nurse anesthetists--noninvasive, continuous, cardiac output monitoring by thoracic electrical bioimpedance. 16.

Risk management and cost containment concerns inherent in central venous cannulation and pulmonary artery catheter insertion have prompted the search for noninvasive cardiac output methods. Thoracic electrical bioimpedance is one such method, revitalized since the early days of space flight. Thoracic electrical bioimpedance measures the impedance changes associated with plethysmographic changes within the thoracic cavity and determines cardiac output. An appreciation of the foundational principles underlying thoracic electrical bioimpedance when compared to the Fick, indicator dilution and Doppler cardiac output monitoring methods will facilitate the nurse anesthetist's understanding and utilization of these modalities.

Comparison of self-instruction methods for teaching diagnostic testing.

In a randomized controlled trial, self-teaching booklets and computer media were evaluated for teaching diagnostic testing to dental students as a foundation for further development of clinical decision making skills. Effectiveness was assessed by pre- and post-tests. Reliability of these test instruments was examined by analyzing the pre- and post-test scores of 49 first year dental students who received no instruction. Forty-one second year dental students were exposed to clinical epidemiological principles applied to endodontic diagnosis through either self-teaching booklets or computer media. No statistically significant difference was found between the mean test scores of the students through self-teaching booklets and computer media. Although first and second year students showed a statistically significant improvement between the pre-test and post-test, the improvement in the second year class was greater. An addendum was later made to the main trial to compare the self-teaching booklet to the traditional lecture format in teaching endodontic diagnosis. Seventy-one third year dental students were exposed to these same materials through either a lecture or the self-teaching booklet and then similarly tested. There was no significant difference between the self-teaching booklet and traditional lecture for the third year students.

Professional Briefcases: innovative resources for the self-directed nurse.

Providing educational activities and learning resources for professional nurses, particularly those who work off-shifts and weekend schedules, is a challenge for staff development personnel. At Northwestern Memorial Hospital, Professional Briefcases offer these self-directed learners an alternative to classroom instruction. The Briefcases can be used in a variety of settings: at home, on the clinical units, or in a resource center. This article describes the contents of the Professional Briefcases and their development and use.
