Evaluation of a comprehensive algorithm for blunt and penetrating thoracic and abdominal trauma.
The objective was to develop a single branched-chain decision tree for both blunt and penetrating thoracic and abdominal trauma and to test its feasibility to track clinical decisions. The algorithm consisted of 14 specific patient management loops and 31 decision nodes. During a 4-month period, the management decisions and clinical course of 434 trauma patients were prospectively observed. ⋯ There were 108 patients with ISS scores between 20 and 50. In this group, mortality was 55 per cent when a major deviation occurred and 5 per cent without major deviations from the algorithm. The authors conclude that the survival of trauma patients may be improved by following the specific management criteria outlined by the algorithm.

Comparative StudyTransfusion therapy in cardiac surgery: impact of the Paul Gann Blood Safety Act in California.
The Paul Gann Blood Safety Act became law in California on January 1, 1990, mandating that patients be informed of the risks and alternatives of blood transfusions. To evaluate the impact of this legislation, the authors compared transfusion therapy in patients undergoing cardiac surgery during 1990 to previous years (1986 to 1987 and 1989). Surgical techniques were unchanged. ⋯ The number of patients not requiring transfusions increased from 28 per cent in 1989 (61 of 219) to 47 per cent in 1990 (104 of 222). A slight but significant decrease in cardiopulmonary bypass time and perioperative blood loss occurred. The authors conclude that this legislation stimulated the surgical team to control blood loss during surgery and to avoid the anticipatory use of component transfusions.
