Modern autotransfusion. Experience with a washed red cell processing technique.

The technique of intraoperative autotransfusion utilizing the Haemonetics Cell Saver is described. This device separates and washes red blood cells removed from the surgical field. Advantages of this unit over others are (1) no systemic anticoagulation is required, (2) circulatory fibrin debris is removed, (3) plasma hemoglobin is removed, and (4) any circulating anticoagulant is removed. Experience with 136 consecutive cases. 101 elective and 35 emergency, is reported. The only complication was coagulopathy, which occurred in 5.1 percent of the cases. It is easily treated with blood component therapy and occurs in those patients in whom greater then 3,500 cm3 of blood is autotransfused. The Cell Saver has proven an important adjunct in surgical patients in whom greater than 1,000 cm3 of blood will be lost, as well as in emergency patients. It provides an efficient, economical and safe method to autotransfuse blood.

Team approach in the management of diabetic foot infections.

Foot infections are common in the diabetic patient. They result from a interplay of neuropathy, ischemia, and metabolic alterations. The team approach in the management of diabetic foot infections can provide the most optimal and probably the most cost-effective care. The cornerstone of treatment is early recognition and prompt intervention. After diagnostic cultures are obtained, infections should be treated with appropriate antibiotics. Bony deformities should be corrected. The vascular status of the patient should be evaluated, and if necessary, treatment should be directed at improving blood flow to the affected foot.

Retroperitoneal approach to the abdominal aorta: revisited.

Experience with retroperitoneal approach to the abdominal aorta for aortic reconstruction in 30 cases is reported. The authors' interest in this exposure stemmed from observations made at the time of scoliosis surgery. The technique was modified and used in poor risk patients and resulted in a significant decrease in operative morbidity and hospitalization. A literature review revealed that several modifications have been described dating back as far as 1836. The authors emphasize technical features and advantages and disadvantages of this approach.
