Abstract:
Objective To explore the application and management of deep hypothermic extracorporeal circulation (DHECC) in surgical procedures. Methods From Dec. 1997 to Dec. 2007, DHECC was applied in 54 patients suffered from great vessel diseases (34/54), complex congenital heart disease (10/54), giant basilar artery aneurysm (5/54), and abdominal tumor with tumor embolus intruding into right atrium or inferior vena cava (5/54) in the General Hospital of PLA. Extracorporeal circulation was performed with arterial perfusion by ascending aorta (n=25), axillary artery (n=18) and femoral artery (n=11), and venous drainage by superior vena cava and inferior vena cava (n=21), right atrium (n=25), and femoral vein (n=8). Clinical data were analyzed retrospectively including extracorporeal circulation (ECC) time, aortic clamping time, deep hypothermic circulation time, the lowest temperature, and the use of ultrafiltration. Results The ECC time was 63-414 (178.55?74.42)min. Aortic clamping time was 16-259 (123.39?52.21) min in 46 patients. Deep hypothermic circulatory arrest (DHCA) was performed in 43 patients, and the duration was 2-109 (30.00?22.37)min. The lowest nasopharyngeal temperature was 13.6-25.7 (19.61?3.40)℃, and the lowest rectal temperature was 15.2-30.5 (21.58?3.63)℃. Ultrafiltration technique was used in 49 cases. 36 of 54 cases (66.7%) self-awakened. Four cases (7.41%) died in the early post-operation period. Conclusion The DHECC can offer a clear and exsanguinated operating field, and is helpful to execute complicated or major operations which are hard to complete with common techniques.
