In Saudi Arabia, the national NHS program has been operational since 2016;however, few studies have evaluated its status, and none have covered all provinces across the country. This cross-sectional retrospective study provides an overview of the program's status across all provinces, focusing on screening coverage rates, referral/fail rates, and follow-up procedures. In 2021, 199,034 newborns were screened, with a coverage rate of 92.6% and an overall referral/fail rate of 1.87%. These performance measures provide a foundation for future progress and improvements. This study highlights the importance of ongoing efforts to enhance the program's effectiveness and sustainability.展开更多

文摘目的探讨听力正常青年短声诱发同侧及对侧听性脑干反应(ABR)的特征,及性别和记录耳侧别(同侧和对侧)ABR的差异。方法对88例(176耳)18~21岁听力正常青年,在70 dB nHL强度下进行同侧及对侧ABR测试,计录同侧波Ⅰ、Ⅲ、Ⅴ潜伏期及Ⅰ-Ⅲ、Ⅲ-Ⅴ和Ⅰ-Ⅴ波间期,对侧波Ⅲ、Ⅴ潜伏期及Ⅲ-Ⅴ波间期,使用方差分析探究性别间差异和同对侧记录差异。结果男性波Ⅲ、Ⅴ潜伏期和Ⅰ-Ⅲ、Ⅲ-Ⅴ、Ⅰ-Ⅴ波间期长于女性(F=13.13~60.82,P<0.001);同侧耳记录的波Ⅲ潜伏期长于对侧记录,波Ⅴ潜伏期和Ⅲ-Ⅴ波间期短于对侧记录(F=22.43~76.18,P<0.001)。结论本研究建立了不同性别听力正常青年在70 dB nHL刺激强度下的同侧及对侧ABR的正常参考值,不同性别和记录耳侧别(同侧和对侧)的ABR波潜伏期和波间期有差异。

文摘目的探讨短纯音刺激皮层听觉诱发电位(cortical auditory evoked potentials,CAEP)对听力评估的价值。方法受试者为听力正常成人19例(36耳),感音神经性聋成人患者21例(21耳),以500、1000、2000和4000 Hz短纯音作为刺激声,在醒觉状态下颅顶电极记录CAEP的N1-P2复合波,分析N1-P2阈值与纯音听阈的相关性,以及两者差值在不同人群中的差异。结果所有受试者四个测试频率的N1-P2阈值与对应频率纯音听阈值的相关系数依次为0.971、0.967、0.958、0.955,呈显著的线性相关;听力正常组36耳500、1000、2000和4000 Hz的N1-P2阈值上限(95%置信区间)依次为32、27、32、39 dB SPL,即正常人阈值上限为32.5 dB SPL;正常人N1-P2阈值与纯音听阈的差值依次为18.9±6.1、11.6±5.9、13.3±7.0、18.7±8.3 dB;感音神经性聋患者两者差值依次为10.3±6.0、6.8±8.9、6.5±9.5、12.9±11.4 dB,四个测试频率的差值在两组人群中的差异均有统计学意义(P<0.05)。结论听力正常人短纯音CAEP的N1-P2平均阈值小于32.5 dB SPL;N1-P2阈值与对应频率纯音听阈相关性非常好,听力评估中使用N1-P2阈值预测听力时应注意刺激声的校准及校正值的使用。
