Abstract: Objective To explore the effect of preoperative interest induction to reduce the stress reaction of pre-school and school-age children during peri-anesthesia period.
Methods A total of 106 children undergoing elective surgery in our hospital from February 1, 2017 to January 31, 2019 were included in the study, and they were randomly divided into observation group and control group, 53 cases each. The control group received routine nursing, and the observation group received combined preoperative interest induction. (1) Observe the degree of anesthesia induction coordination and anxiety self-rating scale(SAS) score; (2) observe heart rate and blood pressure in different periods;(3) observe anesthesia induction cooperation score(ICC) and modified Yale preoperative anxiety scoring(mYPAS) Score; (4) compare plasma cortisol, norepinephrine and epinephrine content in different periods.
Results The degree of anesthesia induction coordination was higher in the observation group than in the control group, while the SAS score was lower, the difference being statistical (P<0.05). Before induction, there was no statistical difference in heart rate or blood pressure between the two groups (P>0.05). After induction, the heart rate and blood pressure during operation were lower in the observation group than in the control group (P<0.05). Before induction, there was no statistical difference in ICC or mYPAS score between the two groups (P>0.05). After induction, the ICC and mYPAS score were lower in the observation than in the control group (P<0.05). At 10min before induction, there was no statistical difference in plasma cortisol, norepinephrine or epinephrine between the two groups (P>0.05). At 5min after induction and during the operation, the level of plasma cortisol, norepinephrine and epinephrine was lower in the observation than in the control group (P<0.05).
Conclusion Preoperative interest induction has a good effect on improving the psychological anxiety and anesthesia induction coordination of children. It can improve the psychological anxiety of children, improve the anesthesia induction coordination of children, and reduce the influence on heart rate, blood pressure, cortisol, epinephrine and norepinephrine. It decreases ICC and mYPAS scores, improves the stress status of children, and has high application value.
