SICU was established in 2001 with 15 beds. There are 1 chief physician and master tutor, 2 deputy chief physicians, 4 attending physicians in the department, one of them with master degree, 3 with doctoral degree and 8 with master degree. There are more than 1,500 critically ill patients are admitted annually. The treatment success rate in the department has remained above 99% for many years.

The department is equipped with advanced medical devices, including advanced central monitoring system, extracorporeal membrane oxygenation (ECMO), NICOM and PICCO cardiac output monitor, fiber bronchoscope, bedside brain function monitoring, aEEG amplitude integrated electroencephalogram, brainstem evoked potential, NIRS near-infrared spectroscopy cerebral blood oxygen monitoring, intracranial pressure monitoring, intra-abdominal pressure monitoring, thromboelastography TEG, NAVA neuromodulated breathing assisted ventilator, high-frequency vibration and normal frequency ventilator, non-invasive assisted ventilation, bedside B-ultrasound and X-ray apparatus, temperature-changing blanket, monitor, defibrillator, concussion sputum excretion apparatus, anti-decubitus air mattress, to ensure that critically ill children receive the best intensive care.

SICU takes the leading position in the field of perioperative treatment on various surgical emergencies and critical ill patients, including severe multiple trauma, severe craniocerebral trauma, craniocerebral tumor, cardiac respiratory arrest, sepsis, various types of shock, stage IV tumor, acute abdomen, ARDS, ventilator-associated pneumonia, pulmonary hypertension and crisis, multiple organ failure, etc. In 2007, SICU applied extracorporeal membrane oxygenation (ECMO) technology to successfully treat 2.8Kg neonates with severe heart failure, setting the lowest ECMO record in Asia and the first successful neonate in China. In 2017, ECMO technology was carried out to treat the patient with severe burns and suffocation and the patient was transferred with ECMO. In 2018, a patient with severe trauma was successfully transferred by the helicopters.

As the vice-chairman unit of the Children's Intensive Physicians Branch of the Chinese Medical Doctor Association, the chairman unit of the Public Safety Professional Committee of the Pediatric Branch of the Chinese Medical Rescue Association and the president unit of the Children's Intensive Physicians Branch of the Zhejiang Medical Doctor Association, SICU undertakes teaching and training of domestic pediatric disaster medical rescue, critical illness and trauma emergency care personnel, and conducts exchange visits, personnel training and project cooperation with many first-class universities and children's hospitals at home and abroad. The department holds the national continuing education project "Children's Critical Care and Trauma First Aid" every year, successfully hosted the International (Asian) Medical Artificial Intelligence Conference in 2018, and undertook the teaching tasks of the American Critical Care Association co-organized a number of learning classes such as pediatric fundamental critical care support (PFCCS) course, advanced pediatric life support, pediatric ICU specialist nurse training, and pediatric hospital infection management. SICU was awarded the honor of “National Worker Pioneer” in 2008, and of“Zhejiang Youth Civilization” in 2013. In 2010, it was rated as “National Clinical Key Specialties” with PICU by National Health Commission. 

SICU is one of the earliest professional pediatric surgical critical care and trauma emergency monitoring centers in the country, with the largest scale, the most complete equipment and the most advanced technology. More than 1,500 critically ill patients are treated every year. A complete set of standardized procedures for the diagnosis and treatment of surgical critical illnesses, trauma emergency, perioperative protection of important organ functions have been established in the department. It takes the leading position in the field of various types of surgery-related acute and critical illnesses, including severe multiple trauma, severe craniocerebral trauma, craniocerebral tumor, cardiac arrest respiratory arrest, sepsis, various types of shock, stage IV tumor, acute abdomen, intra-abdominal hypertension and abdominal compartment syndrome, osteofascial compartment syndrome, ventilator-associated pneumonia, severe pneumonia and ARDS, pulmonary hypertension and crisis, critical metabolic disorders related to nutrition, multiple organ failure, etc. The rescue rate has remained above 99% for many years, successfully saving the lives of countless patients

In 2007, SICU successfully applied extracorporeal membrane oxygenation (ECMO) technology for the treatment of a 2.8Kg neonate with severe heart failure, setting the lowest weight ECMO record in Asia and the first successful neonate rescued by ECMO in China. Subsequently, ECMO was applied to treat refractory cardiopulmonary failure many times. In 2017, ECMO was carried out to treat children with severe burns and suffocation.  Two children who fell off the 17th floor and 18th floor were successfully saved in 2016 and 2018, which attracted the attention of the whole society.

SICU ensures comfortable medical treatment and humanistic care for critically ill children by sedation and analgesia scoring, implementing targeted management. Real-time intracranial pressure monitoring, bedside amplitude integrated EEG monitoring of brain function, brainstem evoked potentials, near-infrared spectroscopy cerebral blood oxygen measurement are used to effectively treat neurologically ill patients. SICU team participated in children's medical rescue in Wenzhou 723 motor vehicle accident, Hangzhou 75 bus arson case, and Fujian Ningde kindergarten fire accident. Since 2018, helicopters have been successfully used to transfer children with severe trauma.
