Anyone facing major surgery has reason to be fearful. In recent years that fear has been magnified by the threat of a terrifying complication: contracting acquired immunodeficiency syndrome from a blood transfusion. Since 1981, 414 Americans have developed the deadly disease after receiving contaminated blood. The introduction last year of screening tests for AIDS antibodies has made the nation's blood supply much safer, but it has not completely eliminated the risk. Thus last week a panel of 13 doctors and blood-bank officials met at the National Institutes of Health in Bethesda, Md., to discuss what more could...
...threat of AIDS is not the only argument for autologous donation. "We would have endorsed this even if the AIDS problem had never come along," says Chalmers. Patients receiving blood other than their own run the risk of allergic reactions and the possibility of complications due to errors in matching blood type. Hepatitis is an even greater danger. Although blood is screened for hepatitis, one type known as non-A, non-B hepatitis cannot be readily detected. In some urban areas, it strikes 7% to 10% of patients receiving blood transfusions...
Still, despite the boost given to autologous donation when President Reagan mentioned it during a recent interview, the panel did not look kindly on its use by people who simply wish to stockpile their blood for a rainy day. The practice, which is made available by a host of new commercial blood banks, might threaten the supply of blood available to the general public. This concerns the American Red Cross. "The present system provides the opportunity for individuals who are healthy to provide blood for individuals who are sick," says Red Cross Vice President Gerald Sandler. If too many people...
...movie's ending is its greatest diappointment. It builds to a series of fast-paced dramatic scenes, full of blood and violence and disappointed love, but than deflates all of the fear and pain and passion by killing off the bad guys and letting the good guy--George--just get up and leave...
...Larry Stephenson has been exploring other applications. By wrapping conditioned skeletal muscle into a fist-size pouch, he has created a mini-pumping chamber that he hopes can be used to boost circulation. Implanted in animals, the pouches, which may be located almost anywhere in the body, have enhanced blood flow as much as 20% for eight hours. Stephenson believes that such auxiliary pumps could reduce the need for risky open-heart surgery. They might also obviate the need for transplants for patients whose hearts are weak but not completely failing. Implanting such a pumping chamber would be simpler...
