儿童鼓膜置管后正压注药的临床观察

Study on the Positive Medicine-administration after Tympanic Tube Insertion in Children

目的:探讨儿童分泌性中耳炎鼓膜置管后正压注药熏在保持管的通畅促进咽鼓管功能恢复方面的作用。方法:治疗组耳膜置管后第2天起应用正压注药仪将药液经中耳加压注入鼻咽腔,连续7d。对照组耳膜置管后不做耳道正压注药。2组患儿定期门诊复查,行耳镜及阻抗检查,记录检查结果。结果:治疗组术后戴管时间为(228.9±85.5)d,对照组术后戴管时间为(173.0±67.9)d,有效率治疗组78.62%(114/145),对照组61.61%(69/112),2组比较差别均有统计学意义。结论:此方法可延长带管时间,改善咽鼓管功能,减少分泌性中耳炎复发。

Objective： To evaluate the effects of positive administration on keeping the tube open and recovering the eustachian tube function in children otitis media effusion （OME）. Methods： The medicine was pressed into the nasopharyngeal cavity for 7 days by the positive medicine-administration equipment 1 day after tube insertion in treatment group. No treatment was performed in control group. All children were followed up by otoscopy and tympanometry. Results： The time of ventilation tube taking were （228.9 ± 85.5） d and （173 ± 67.9） d in treatment group and control group respectively. The effective rates were 78.62% （114/145） and 61.61% （69/112） in treatment group and control group respectively. There was a significant difference between the two groups. Conclusion： This method can prolong the tube taking time, improve the eustachian tube function, and reduce the recurrence of OME.
