heart surgery

Julie Uchitel

This sound is a recording of an attending physician and a resident discussing the EEG of a patient in the Epilepsy Monitoring Unit at Duke Children's Hospital. The patient they are discussing underwent deep hypothermic circulatory arrest (DHCA) during a heart surgery. Deep hypothermic circulatory arrest is a surgical technique in which the body is cooled to reduce the rate of blood flow and thereby reduce the chance of stroke-related or oxygen deprivation-related brain injury. The patient's brain activity is monitored via EEG during this time to confirm that the patient is safe. In the recording, the resident asks questions about this technique and the attending physician answers. The attending notes that the patient has a seizure during DHCA. "T5" represents an area of the brain known as the temporal lobe where activity was recorded. Terminology such as "sharply contoured" and "dysfunction" refer to the types of patterns the physicians are seeing on the EEG. Recorded using a Zoom recorder.
