ANCHOR LEAD: A CHEMICAL FOUND COMMONLY IN PVC BASED MEDICAL DEVICES MAY BE HARMFUL AT VERY LOW LEVELS, ELIZABETH TRACEY REPORTS
Many patients who’ve undergone heart bypass surgery report persistent problems with short term memory, fatigue, and food that doesn’t taste good. Artin Shoukas, a cardiovascular researcher at Johns Hopkins, who has himself had this experience following heart surgery, thinks he has found the culprit.
SHOUKAS: The wet welding agent, which is called cyclohexanone, used in cardiopulmonary bypass, in dialysis, and in IV bags, is toxic at normal levels that you would see in patients, to cardiac function, vascular function, and neuronal function. What we have really shown is there can be morbidities associated with this substance within the human population. :30
Shoukas and colleagues are analyzing blood samples from people who’ve had surgery or other exposures to cyclohexanone to prove an association. At Johns Hopkins, I’m Elizabeth Tracey.
