Methods: from July 2020 to December 2021, 110 cases of acute infantile enteritis were selected for clinical study. The children were divided into two groups by random number table method, with 55 children in each group. The control group applied routine guidance nursing intervention, and the observation group applied health education nursing intervention to obtain and compare the nursing effect, disease awareness (enteritis inducement, enteritis manifestation, enteritis treatment, feeding of children, child care, precautions), complication rate (stomach distension, abdominal pain, pus and blood stool), nursing quality (service attitude, disease cognition, psychological adjustment, symptom treatment, life care) between the two groups. Results: the effective rate of nursing in the observation group was higher than that in the control group. After nursing, the disease awareness score of parents in the observation group was higher than that in the control group. The complication rate in the observation group was lower than that in the control group. The five nursing quality scores in the observation group were higher than that in the control group, with statistical significance (P < 0.05). Conclusion: the application of childrens health education and nursing intervention in acute infantile enteritis has significant nursing effect, higher disease awareness, higher nursing quality score, and lower complication rate.展开更多

Methods: Controlled observation method was adopted in the clinical and experimental study. Results: There was no significant difference in the treatment of dehydration between the ZXBYM group and oral rehydration solution (ORS) group (P>0.05), at the same time it was more effective for ZXBYM to eliminate such symptoms as vomiting and abdominal distension (P<0.01). In addition, it was confirmed that the ion concentration of sodium, potassium, chlorine, glucose and osmotic pressure in the mixture was similar to those in ORS. Animal experiment showed that ZXBYM has the effect of rat intestine peristalsis suppression and water absorption promotion in colon. And there was statistical difference in antidiarrhea effect between the mixture and ORS (P<0.01). Conclusion: ZXBYM is an effective mixture in the treatment of diarrhea with dehydration. It has a good prospect for the development and application.展开更多
