Objective:To investigate the clinical application effect of two nasal obstruction fixation methods on transnasal high-flow oxygen therapy(HFNC)in children in PICU.Methods A total of 125 children with HFNC admitted to the Children's Intensive Care Unit(PICU)of Zhangzhou Hospital were randomly divided into experimental group(60 cases)and control group(65 cases).The control group adopted the "王"font fixed，and the experimental group adopted the "Y" font fixed.The 24 hour nasal congestion shedding times，nasal mucosa injury，philtrum skin injury and cheek injury were compared between the two groups.Results In the experimental group，the number of nasal congestion shedding，nasal mucosa，philtrum skin and cheek skin injuries were all less than those in the control group，and the difference was statistically significant(P＜0.05).Conclusion When children use HFNC，using the "Y" shaped nasal obstruction fixing method can obviously reduce the number of nasal obstructionfalling off，reduce the incidence of nasal mucosa，human skin and cheek skin injuries，and improve the comfort of children，which is feasible.

Objective To explore the intervention value of implementing standardized nursing procedures in children with PICU fecal incontinence dermatitis. Methods Retrospective analysis from January 2021 to August 2021， 136 patients with urinary incontinence and risk of incontinent dermatitis were selected from the PICU patients admitted to our hospital from January 2021 to August 2021. The patients were divided into control groups (67 patients， the implementation of conventional nursing procedures) and the intervention group (69 cases， the implementation of standardized nursing procedures) according to the time of admission to PICU， compared the probability， severity， skin cleansing and dressing changes， average daily nursing time， and duration of incontinent dermatitis in the two groups. Results A total of 12 cases (17.91%) of incontinent dermatitis occurred in the control group， and a total of 4 cases (5.80%) of incontinent dermatitis occurred in the intervention group， with significant differences between the groups (P＜0.05). The two groups were compared in terms of skin cleansing and dressing changes， average daily care time， and duration of incontinent dermatitis， the above indicators of the control group exceeded the intervention group， and there were statistical differences between the groups (P＜0.05). Conclusion Implementing a standardized nursing process for children with PICU incontinence can not only effectively prevent and reduce the risk and severity of incontinent dermatitis， but also shorten the duration of symptoms in children， save nursing time， reduce nursing workload， and improve nursing care work efficiency is positive for both doctors and patients.
