Abstract:Objective To approach the influence of plastic leak mount on colostomy children. Methods From November 2016 to October 2017, in Xinhua Hospital Affiliated to Shanghai Jiaotong University, 80 colostomy children were selected. They were divided into two groups by different treatment method, control group (regular ARC replacement process) 40 cases and detection group (regular ARC replacement process+plastic leak mount) 40 cases. The colostomy pocket replacement time, colostomy pocket replacement interval time of two group were detected, the DQ score, around colostomy skin score of two group before and after nursing were detected, the around colostomy dermatitis occurrence of two groups were detected. Results The colostomy pocket replacement time of detection group was shorter than control group, and the colostomy pocket replacement interval time was longer than control group, the differences were statistically significant (P < 0.05). The DQ scores, around colostomy skin scores before nursing of two group were compared, the differences were not statistically significant (P > 0.05), after nursing, the DQ scores of control group and detection group were higher than before nursing, the around colostomy skin scores was lower than before nursing, the DQ scores of detection group after nursing was higher than control group, the around colostomy skin score was lower than control group, the differences were statistically significant (P < 0.05). The around colostomy dermatitis occurrence of detection group was better than control group, the difference was statistically significant (P < 0.05). Conclusion The application of plastic leak mount on colostomy children, it can increase application efficiency of colostomy pocket and DQ,improve around colostomy skin score, decrease around colostomy dermatitis rate, and it is worth to be used.
