Founded in 1981, CICU was independent from the surgical intensive care unit in January 2016. This is a young and battle-hardened department, which integrates medical, teaching and scientific research. It has 2 chief physicians, 3 attending physicians, and 3 resident physicians, 3 of them with doctoral degree and 5 with master degree. There are currently 18 beds, receiving about 1500 cases of critically ill children with various types of complicated congenital heart diseases (transposition of the great arteries, total anomalous  pulmonary venous return, ulmonary atresia, left heart dysplasia syndrome, interruption of aortic arch, truncus arteriosus, etc.) and  thoracic surgeries （ neonatal diaphragmatic hernia, neonatal esophageal atresia, etc.), from Zhejiang Province and other provinces and cities. The cure rate in the department is 98.7%.

The department is equipped with advanced medical equipments ，such as aadvanced vital signs central monitoring system, various non-invasive auxiliary ventilation equipment and constant frequency high frequency ventilator, bedsid X-Ray       machine,temperature changing blanket treatment instrument, bedside fiber bronchoscope, bedside 24-hour continuous EEG monitor, bedside defibrillator, bedside ultrasound machine, near-infrared tissue blood oxygen parameter non-destructive monitor, to ensure that the best quality care are available for all critically ill children. It carries out various of diagnosis and treatment technologies, including the comprehensive treatment technology of ECMO, VAD, NAVA mechanical ventilation, NIRS monitoring, PICCO cardiac displacement monitoring, bedside ultrasound cardiac function monitoring, dynamic brain function monitoring, and pulmonary hypertension, bedside fiber bronchoscope alveolar lavage, bedside peritoneal dialysis, temporary pacemaker, bedside thoracotomy, etc. In addition, it pays attention to the exchanges and cooperation with many domestic and foreign first-class children's hospitals for personnel training and research projects.

After years of clinical practice and research, Cardiac Intensive Care Unit has formed a complete series of standardized treatment and care of perioperatvie period for critically ill patients, including congenital heart diseases, open heart surgery, heart failure, low cardiac output syndrome, pulmonary hypertension crisis, severe arrhythmia, shock, respiratory failure, capillary leak syndrome. Ventilator management, liquid management and nutrition support, perioperative organ protection strategies, coagulation management of critically ill patients have reached the leading position, especially in the perioperative management of neonatal critical and complicated congenital heart diseases.

The department annually treats about 1,500 critically ill patients with complicated congenital heart surgeries, including complete large vessel dislocation, single ventricle, complete atrioventricular passage, left ventricular dysplasia syndrome, right ventricular double outlet, complete pulmonary venous drainage, permanent arterial trunk, aortic arch interruption, corrected large vessel dislocation, pulmonary artery atresia, etc.; and thoracic surgery patients with congenital diaphragmatic hernia, esophageal hiatal hernia, congenital diaphragmatic eventration, mediastinal tumors, complex congenital heart mosaic surgery, etc. It successfully carried out postoperative management of tracheal stenosis with pulmonary artery sling combined with tracheal stenosis with right bronchial bridge, and Norwood stage I surgery for left heart hypoplasia syndrome. The development of ECMO technology and VAD technology in the department has greatly improved the cure rate of critical congenital heart diseases, reaching the domestic leading level.
