Objective To understand the nutritional care experience of families of children with short bowel syndrome secondary to intestinal failure，and to provide references for developing scientific and effective nutritional care programs. Methods Using the purposive sampling method，a total of 16 parents of children with intestinal failure secondary to short bowel syndrome who were admitted to a tertiary children’s hospital in Zhejiang province from July 1 to December 31，2022 were selected as the research subjects. 2 semi-structured interviews were conducted a day before and 2 to 3 weeks after the discharge of the children. The Colaizzi 7-step analysis method was used to analyze the interview data. Results It could be summarized into 4 themes and 6 subthemes：①Nutritional care distress changes in stages：feeling overwhelmed in the acute phase；there were more problems in tube feeding，tube maintenance，and complementary food production during the compensatory period；the burden of home nutritional care increased during the recovery period. ②The role conflict between nutritional care-parents caused self-blame and guilt. ③Positive experiences from peer and healthcare support were obtained. ④The medical staff was expected to provide more nutritional support services；it is hoped that systematic nutritional care courses will be set up，and it is hoped that home nutrition care guidance will be given during follow-up after discharge. It is hoped to implement home parenteral nutrition support. Conclusion Parents of children with intestinal failure secondary to short bowel syndrome have many difficulties in nutritional care and change in stages. Their care experience is affected by the relationship with peers，spouses and medical staff，and they look forward to family nutrition support services. Medical staff can assess parents’ nutritional care distress at different stages，carry out systematic and phased nutritional care course training，give psychological counseling and support in time，and provide home parenteral nutrition support services，so as to improve the nutritional status of children.

Objective To investigate the effects of hammock positioning on the growth and development indexes of premature infants,such as weight,body length and head circumference. Methods From January to August 2020,106 premature infants admitted to a tertiary children’s hospital in Hangzhou were selected as the research subjects. They were divided into an experimental group（n=53） and a control group（n=53） by random number table method. The control group was treated with conventional heating box. The experimental group was treated with hammock positioning in addition to conventional warm box care. The growth and development of infants in the 2 groups were compared. Results The weight gain of premature infants in the experimental group at the 2nd to 4th weeks,the 24 - hour sleep duration and the discharge weight were higher than those of the control group;the number of days required to restore birth weight and the length of hospital stay are lower than those of the control group,and the difference was statistically significant（P<0.05）. After using hammock therapy,the heart rate and respiratory rate of the experimental group decreased,and the oxygen saturation increased,and the difference was statistically significant（P<0.05）. Conclusion Hammock positioning plays a positive role in promoting the average weight gain per week,reducing the number of days to regain birth weight,increasing the duration of 24 hours sleep,stabilizing vital signs of premature infants and reducing the length of hospital stay,which can effectively promote the growth and development of premature infants.
