This article will discuss how induced hypothermia affects the patient undergoing coronary artery bypass graft surgery. Nursing interventions differ greatly for cardiac procedures done on cardiopulmonary bypass versus off-bypass procedures, such as "keyhole." Induced hypothermia, cardiopulmonary bypass, cardioplegia, and various delivery techniques of cardioplegia, and postoperative hypothermia will be discussed.
