1.Advances in prevention and control of nosocomial Infection in neonatal intensive care unit
International Journal of Pediatrics 2010;37(1):98-100
The incidence of nosocomial infections in the neonatal intensive care unit(NICU) is high. Nosocomial infections is one of the most common causes of neonatal death in critically ill neonates. Strategies for the prevention nosocomial infections include hand hygiene practices,prevention of central venous catheter-related infection and ventilator-associated pneumonias, antifungal prophylaxis, skin care, early enteral feeding and probioties. Effective prevention and control nosocomial infections in NICU may decrease neonatal mortality,hospitaliztion stay and hospital costs.This review focuses on the latest preventive strategies for nosocomial infections in NICU.

Patients with respiratory crisis occupied a large numbers in extracorporeal membrane oxy-genation(ECMO) group. ECMO is able to give a plenty amount of gas exchange for body essential metabolic needs by ECMO oxygenator whoever the lungs are of function or not. The key indications for respiratory ECMO are that the patient had no response to all medical treatment except ECMO,and the origin cause of the disease is potentially recoverable. Besides the contraindications and accessibility, ECMO has no special settings among the different ages or cause of diseases. The VV-ECMO is preferred for respiratory support. VA-ECMO should be considered if cardiovascular failure exists. ECMO may offer a powerful respiratory support to patient with critically ill conditions until recovery. The outcomes are influenced by some factors including the reversibility and the cause of diseases.

10. Extracorporeal membrane oxygenation in children with septic shock
Chinese Pediatric Emergency Medicine 2018;25(7):503-506
Septic shock is the most serious type of sepsis.Despite detailed treatment recommendations at domestic and abroad guidelines, some patients with septic shock have no response to treatment, and progress rapidly and develop into multiple organ failure leading to death.The recent guidelines and consensus of septic shock recommended extracorporeal membrane oxygenation(ECMO)as the last resort rescue for children with septic shock.However, worldwide consensus for ECMO application in children with septic shock is not available at the present time.Clinical conditions that ECMO should be initiated, ECMO catheterization method and prognosis of children received ECMO support are still controversial.The aim of this article was to review ECMO application in children with septic shock.
