小儿渗出性中耳炎是耳科医生感到棘手的疾患之一。据统计4～7岁小儿的发病率高。多数患儿不能配合治疗,当然也有自然治愈者,但对其预后难以预测。小儿渗出性中耳炎的发病,主要是咽鼓管开闭和排泄功能不良。为此作者等将中耳腔换气的范围扩展到乳突气房,进行一时性高气压置换,取得良好效果。方法是带患儿进高压环境(氧舱),在20～30分钟内从正常大气压加压至2个大气压,再以约5分钟的时间从2个大气压减到1.8大气压;然后又从1.8加到2大气压;……如此反复5～10次,最后仍以同加压时同样的时间减压至正常。这时要注意在接近1.8大气压时,可有耳内压迫感。之所以在高气压下进行气压变动是基于在常压下吞咽时0.2气压压差的变化咽鼓管即有开闭运动,而在高压下咽鼓
Pediatric exudative otitis media is one of the most troubling conditions for otologists. According to statistics, 4 to 7-year-old children have a high incidence. Most children can not cooperate with the treatment, of course, natural cure, but its prognosis is unpredictable. The incidence of infantile exudative otitis media, mainly eustachian tube opening and closing and excretion dysfunction. To this end, etc. the scope of the middle ear cavity ventilation extended to mastoid air room, temporary high pressure replacement, and achieved good results. The method is to bring children into a hyperbaric environment (oxygen chamber), pressurized from normal atmospheric pressure to 2 atmospheres within 20 to 30 minutes and then from 2 atmospheres to 1.8 atmospheres in about 5 minutes; and then from 1.8 plus To 2 atmospheres; ... ... so repeated 5 to 10 times, and finally still with the same pressure at the same time decompression to normal. At this time should pay attention to near 1.8 atmospheres, there may be pressure within the ear. The reason why the barometric pressure changes under high pressure is based on the change of pressure difference of 0.2 barrels when swallowing under the normal pressure, that is, the opening and closing movement of the eustachian tube,
