摘要
目的通过脑干听觉诱发电位(BAEP)观察新生儿在实施3.0T磁共振(MR)检查后听力传导系统的变化,探讨3.0TMR是否对新生儿听力系统造成不良影响。方法选取2013年8至12月入住北京军区总医院附属八一儿童医院足月新生儿监护中心行3.0TMR检查的患)L49例,剔除可导致听力障碍的外耳发育畸形等异常者。比较患儿在MR前后双耳BAEP波Ⅰ、Ⅲ、Ⅴ的潜伏期以及峰间期的差异,采用SPSS16.0软件进行统计学分析。结果MR检查前后,BAEP各指标分别为:(1)潜伏期:左耳Ⅰ波(1.96±0.22)ms比(1.95±0.30)ms,右耳Ⅰ波(1.96±0.22)ms比(1.97±0.27)ms,左耳Ⅲ波(4.79±0.23)ms比(4.85±0.28)ms,右耳Ⅲ波(4.78±0.24)ms比(4.77±0.31)ms,左耳V波(7.10±0.24)ms比(7.12±0.33)ms,右耳V波(6.76±0.32)ms比(7.04±0.39)ms,MR前后两耳各波潜伏期比较差异均无统计学意义(P均〉0.05)。(2)峰间期:左耳Ⅰ-Ⅲ波峰间期(2.83±0.23)ms比(2.86±0.27)ms,右耳Ⅰ-Ⅲ波峰间期(2.82±0.24)ms比(2.80±0.17)ms,左耳Ⅲ-Ⅴ波峰间期(2.31±0.28)ms比(2.31±0.29)ms,右耳Ⅲ-V波峰间期(2.26±0.27)ms比(2.26±0.23)ms;左耳Ⅰ-Ⅴ波峰间期(5.11±0.40)ms比(5.13±0.35)ms,右耳Ⅰ—Ⅴ波峰间期(5.07±0.39)ms比(5.07±0.36)ms,MR前后两耳各波峰间期比较差异均无统计学意义(P均〉0.05)。结论3.0TMR检查对患儿BAEP各指标无明显影响,可能对新生儿听力无明显影响。
Objective To evaluate whether or not the 3. OT magnetic resonance (MR) scanner noise has ad- verse influence on neonatal hearing by using brainstem auditory evoked potentials(BAEP). Methods Forty - nine in- patients who received the MR examination were enrolled in this study from Aug. to Dec. 2013, admitted to the Bayi Children's Hospital Affiliated to Beijing Military General Hospital. The Ⅰ, Ⅲ, Ⅴ wave latencies and the inter - peak intervals before and after the MR scan were compared by using SPSS 16.0 software. Results The BAEP results before and after MR examination respectively : ( 1 ) The latencies were: left ear Ⅰ wave ( 1.96 ± 0.22 ) ms vs ( 1.95± 0.30) ms, right ear Ⅰ wave ( 1.96 ± 0.22) ms vs ( 1.97 ± 0.27 ) ms, respectively; left ear Ill wave (4.79 ± 0.23 ) ms vs (4.85 ± 0. 28 ) ms,right earlllwave(4.78 ±0.24) ms vs (4.77 ± 0. 31 ) ms,respectively;left ear V wave (7.10 ± 0.24) ms vs (7.12 ±0.33) ms,right ear V wave (6.76 ±0.32) ms vs (7.04 ±0.39) ms,respectively(all P 〉0.05). (2)The in- ter - peak intervals were: left ear Ⅰ -Ⅲ inter - peak interval (2.83 ± 0.23 ) ms vs (2.86 ± 0.27 ) ms, right ear Ⅰ - Ⅲ inter-peak interval (2.82 ±0.24) ms vs (2.80 ±0. 17) ms,respectively;left ear Ⅲ- V inter - peak interval (2.31 ± 0.28 ) ms vs (2.31 ± 0.29) ms, right ear Ⅲ - V inter - peak interval (2.26 ± O. 27 ) ms vs (2.26 ± 0.23 ) ms ,respectively;left ear Ⅰ - Ⅴ inter- peak interval (5. 11 ± O. 40 ) ms vs (5. 13 ± 0. 35 ) ms, right ear Ⅰ -Ⅴ inter - peak interval ( 5. 07 ± 0. 39 ) msvs (5.07±0.36) ms,respectively(allP〉0.05).Conclusion The3.0TMR mav have no adverse influence on neonatal BAEP.
