Objective To survey the parents′satisfaction of clinical decision who have children with end-staged liver diseases. Methods The Questionnaire of Satisfaction of Clinical Decision was used as the instrument. Results The parents′satisfaction score 3 months after the surgery was (71.2 ±3.5) points, while 1 year after the surgery was (68.3±4.4) points, and the difference between them was not statistically, P value was more than 0.05. Besides, the satisfaction showed significant difference on the factors of education and monthly income. F values were 5.258 and 6.328, and P values were both less than 0.05. The stronger the education background was, the higher the satisfaction was. And so the monthly income was. Conclusions The parents have higher satisfaction of clinical decision, and the education and monthly income are the factors affecting the satisfaction.

Objective: We observed the effect of the opening and closing pressure sensors on the pediatric liver transplantation. Methods: The 100 cases of pediatric patients who suffered biliary atresia were chose to this study from July 1^st 2018 to Dec 31^st 2018. They received the living donor liver transplantation. The samples were divided into control group and test group according to the random number table. We observed the volume of blood lost during the process of blood sample collecting. The hemoglobin (HB) and infection rate of catheter were also recorded. Results: The test group didn′t lose blood when collecting the sample, and the time of collecting the blood sample in the test group was (22.0 ± 4.2) s, which was shorter than that of in the control group (47.0 ± 7.8) s, the difference was significant, t=9.321, P<0.05. The difference of HB and infection rate of catheter after 24 hours between two groups was not significant, P>0.05. Conclusion The closing pressure sensor may be more advanced when used to avoid the loss of blood and prevent the infection.
