Survey on the prevalence of continuous blood purification in Chinese pediatric critical care / 中华儿科杂志

ABSTRACT

Objective@#To investigate the current application status of continuous blood purification (CBP) technology and equipment in pediatric intensive care unit (PICU) in China.@*Methods@#A cross-sectional survey was conducted to understand the current popularization of CBP technology and equipment, the management of CBP equipment and consumables, and the application of CBP in different diseases. A questionnaire named Application Status of Continuous Blood Purification Technology was applied. Children's hospitals and polyclinic hospitals with the pediatric qualification (pediatric emergency or critical care unit members of Chinese Medical Association and Chinese Medical Doctor Association) were selected.@*Results@#From December 2016 to February 2017, 53 hospitals completed the questionnaire, including 7 in northeast, 6 in north China, 16 in east China, 9 in south China, 5 in central China, 4 in the northwest, and 6 in the southwest region. Continuous renal replacement therapy (CRRT), the most widely used technology, was carried out in 51 hospitals. Other technologies were peritoneal dialysis (IPD) (n=37), artificial liver support (ALSS) (n=26) and blood adsorption (PA) (n=13). There were 107 CBP machines in the 51 hospitals used CBP technology, with an average of 2.10/hospital. In 36 hospitals CBP machines were managed independently by PICU (70%). Hospitals made their own displacement liquid (n=40, 78%), or purchased displacement liquid (n=11, 22%). Hospitals prepared dialysate on their own (n=38, 75%), or purchased dialysate (n=13 hospitals, 25%). In 46 (90%) hospitals, hemodialysis catheter was placed independently by PICU doctors. The routine operation and maintenance of CBP were mainly completed by the PICU nurses in 36 hospitals (71%). There were 39 hospitals (76%) where professional nurses manage and maintain CBP. Puncture sites were femoral vein (n=26, 51%), internal jugular vein (n=21, 41%) and venae subclavia (n=4, 8%). Forty-two hospitals (82%) selected B-mode ultrasound positioning and guidance when performing internal jugular vein puncture. A total of 40 (78%) hospitals have developed post dilution and combined dilution techniques during the implementation of CBP. The most common indications of CBP technology were different in different regions. They were sepsis in northeast (24.0%, 243/1 011) and east China region (32.0%, 982/3 069), multiple organ dysfunction syndrome in south China (29.2%, 444/1 520), north China (15.8%, 126/796), and southwest region (30.1%, 460/1 526), drug poisoning in central China region (21.6%, 325/1 506), and renal failure in northwest region (53.0%, 44/83).@*Conclusions@#CBP technology is widely used in the field of pediatric severe diseases in China. The eastern regions possess more CBP equipment than the western regions. CBP is widely used in the treatment of sepsis.
