Abstract：ObjectiveTo investigate the application effect of transoral catheterization in pediatric esophageal pacing by using childrens breathholding intermittent interval after crying, so as to improve the success rate of electrode catheterization in pediatric esophageal pacing, shorten the examination time, and reduce their pain and complications in children. MethodsA total of 60 children aged 0-12 years were selected as research objects. They were divided into observation group and control group with 30 cases in each group by random sampling. Without any technique, in the control group the esophageal electrode was inserted through the nasal cavity, and the depth of the transnasal esophageal electrode was the distance of the nasal tipearlobexiphoid with 5 cm subtracted. In the observation group, by using a transient breathholding interval after childrens cry, esophageal electrode was quickly inserted through the oral cavity, and its depth was the distance from the hairline to the xiphoid with 5 cm subtracted. The firstattempt success rate, the incidence of complications, and the time for placing esophageal electrode in the two methods were compared. ResultsThe firstattempt success rate of catheterization in the observation group was 100%, higher than the rate of 86.67% in the control group (χ2=4.286, P=0.038). The total incidence of complications in the observation group was 3.33%, which was lower than the incidence of 23.33% in the control group (χ2=33.611, P<0.01). The time of catheterization in the observation group was lower than that in the control group ［(74.15±12.35)svs. (152.34±15.24)s; t=7.494, P<0.01］. ConclusionTaking advantage of the short breathholding intermittent interval after childrens crying, rapid insertion of esophageal electrodes through the oral cavity could improve the firstattempt success rate of catheterization in pediatric esophageal pacing. It could significantly reduce the incidence of complications, and shorten the time for catheterization procedure, which is worthy of being promoted in clinical practice.
