Objective:To explore the effect of health education under KABP model on negative emotions and pregnancy outcome in patients with high-risk pregnancy.Methods:Choosing 180 patients with high-risk pregnancy as the research objectsfrom June 2014 to May 2016 in our hospital,we divided the patients into two groups using the random number table method,each for 90 cases.The control group was given comprehensive nursing;the observation group was given health education under KABP model on the basis of control group.We compared the differences of negative emotions and pregnancy outcome between the two groups.Results:Before nursing,there was no significant difference of the Self-Rating Anxiety Scale (SAS) score and Self-Rating Depression Scale (SDS) score between the two groups (P ＞ 0.05).After intervention,the fetal distress,neonatal asphyxia and postpartum hemorrhage rate of observation group were significantly lower than control group,while the rate of natural delivery of observation group was significantly higher than control group (P ＜ 0.05).Nursing satisfaction of observation group was significant higher than control group (P ＜ 0.05).Conclusion:The health education under KABL model helps to significantly improve negative emotions and pregnancy outcome in patients with high-risk pregnancy,thus significantly improve nursing quality.It is worthy of clinical popularization and application.
