只拿医院检查报告就给孩子验配助听器?这样会害了孩子
很多家长拿着医院客观检查报告去助听器验配中心为孩子咨询。大部分会很着急地询问:“根据这个结果,要不要配助听器?要配什么样的助听器?”家长们却不知道这样做其实是错误的。● 首先,孩子不等于微缩的成人。
婴幼儿听力损失和成人语后聋有着非常大的不同:
1、孩子需要依赖助听器感知这个世界,先能够听,才能够学习语言。
2、由于年龄较小,他们无法主动配合做各种主观检查,需要专业验配师引导才能进一步测试听力,得到最贴近真实听力情况的检查报告。
3、最重要的是婴幼儿一天一个变化,生长发育非常快,所以外耳道的声学特性也会一直改变,即同样的声音进入到不同容积的耳道内所发生的变化也是不同的。其中,行为测听是判断儿童听力损失程度的金标准,也是儿童助听器验配调试的首选参考数据,根据年龄分为以下几种方法:
1. 行为观察法 1-6个月
2. 视觉强化测听 6-30个月(建立条件反射)
3. 游戏测听 ≥24个月
4. 纯音测听 ≥5岁 (测听方式同成人)由于我们刚才说的婴幼儿配合程度的不确定性,大大增加了主观测试的难度,所以一些不专业的验配中心会直接使用客观报告进行验配,这种方法非常不可取。
原因在于孩子无法描述自己的实际感受。若保守调试,孩子会因为没有足够的声音刺激导致助听效果不理想,影响语言能力与智力发育,若助听器增益补偿过大,则有可能进一步损伤孩子的听力。
所以,客观报告或者说单一的检查结果是不能用于判断孩子真实听力情况的,孩子的听力情况是需要结合病史、医院的客观检查报告和主观行为测听的结果来交叉验证、综合判断后,再进行调试的,且需要定期复查主观听力,继续调整。

    I'd like to withdraw $100, please generic claritin d cvs  Fitch views the proposed acquisition of Celesio by MCK as strategically sound, as it offers the potential for better buy-side drug pricing and additional growth opportunities outside the largely penetrated U.S. market. The realization of these benefits, however, is likely to take several years. Fitch sees relatively few financial synergies in the near term.
