Therapeutic Hypothermia Treatment for Heart Attack


A REALLY COOL MEDICAL TECHNIQUE IS SAVING LIVES FOLLOWING CARDIAC ARREST. WELCOME TO MEMORIAL HEALTH AND YOU. WITH US TODAY IS DR. JOSEPH BOSARGE, MEMORIAL INTENSIVE CARE UNIT MEDICAL DIRECTOR. DR. BOSARGE WHAT IS THE PRINCIPLE BEHIND HYPOTHERMIA THERAPY? THERAPEUTIC HYPOTHERMIA IS BASED ON OBSERVATIONS OF DROWNING VICTIMS IN ICY WATER BEING REVIVED AFTER LONG PERIODS OF TIME WITH LITTLE OR NO BRAIN DAMAGE. FOLLOWING SOME KEY STUDIES IN THE LAST DECADE, IT WAS ADOPTED BY THE AMERICAN HEART ASSOCIATION FOR USE IN POST CARDIAC ARREST PATIENTS WHO REMAINED UNCONSCIOUS. DURING A CARDIAC ARREST BLOOD FLOW TO THE BRAIN IS INTERRUPTED TISSUE DAMAGE OCCURS AND CAN CONTINUE TO OCCUR EVEN AFTER BLOOD FLOW IS RESTORED. THERAPEUTIC HYPOTHERMIA MINIMIZES THIS DAMAGE AND GIVES PATIENTS THEIR BEST POSSIBLE CHANCES FOR A MEANINGFUL RECOVERY. SO, HOW DOES IT WORK? IN THE INTENSIVE CARE UNIT THE PATIENT IS HEAVILY SEDATED. COOLED WATER IS CIRCULATED THROUGH INSULATED PADS LOWERING THE BODY’S CORE TEMPERATURE TO APPROXIMATELY 92 DEGREES FOR 24 HOURS. THIS SLOWS DOWN METABOLISM AND PROTECTS THE BRAIN AND OTHER VITAL ORGANS. THEN WE GRADUALLY RE-WARM THE PATIENT BACK TO NORMAL TEMPERATURE. DURING THIS TIME THE PATIENT IS CLOSELY MONITORED IN OUR I.C.U. OVERALL, IT CAN MEAN SHORTER I.C.U. STAY, LESS TIME ON A VENTILATAOR, IMPROVED NEUROLOGIC OUTCOMES AND A BETTER SURVIVAL RATE. AMAZINGLY, SOME PATIENTS CAN RECOVER WITH THIS THERAPY EVEN IF THE HEART HAS BEEN STOPPED FOR 20 MINUTES OR LONGER. THANK YOU, DR. BOSARGE.
