Measurement of Cerebral Flow Using Transfontanellar Doppler in Infants Under Cardiopulmonary Bypass

Intraoperative Trans-fontanel Cerebral Ultrasonography in Infants During Pediatric Cardiac Surgery Under Cardiopulmonary Bypass

Transfontanellar Doppler can measure the velocity at both the carotid artery and the anterior cerebral artery during cardiopulmonary bypass in congenital heart disease patients. This study can provide reference value of appropriate cerebral blood flow velocity during pediatric cardiac surgery.

Inclusion Criteria:

1. the patients less than 1 year of age undergo congenital heart surgery with cardiopulmonary bypass
2. written informed consent is obtained from their guardians in accordance with the requirements of the local ethics committee

Exclusion Criteria:

1. synostosis
2. skull abnormality or fracture
3. epidural hematoma, scalp hematoma
