A method of maintaining thermal homeostasis during cardiac catheterization in newborns

This device has been designed to maintain thermal homeostasis in newborns undergoing cardiac catheterization. It is easily constructed from materials available in any hospital, and it is safe and effective. It consists of a warming coil and a delivery unit made from Plexiglas which encloses the patient. In addition to maintaining a neutral thermal environment, it allows for the selection of any desired oxygen concentration by simply blending the gas mixture before warming and delivery. Since using this device we have had no problems or complications related to thermal stress during catheterization of the neonate.
