摘　　要：目的：探讨脑干听觉诱发电位（BAEP）对足月小于胎龄儿（TSGA）脑功能及听力检测的价值。方法：测定TAGA儿和TSGA儿的BAEP并比较其差异。结果：TSGA组Ⅰ波出波率、各波分化良好率及潜伏期、Ⅲ-Ⅴ及Ⅰ-Ⅴ波间期、Ⅰ和Ⅲ波波幅与TAGA组比较差异有统计学意义（P〈0.05）。结论：BAEP是TSGA脑干听中枢功能异常和听力障碍早期筛查的有效方法。Objective： To explore the value of brainstem auditory evoked potential （BAEP） in the detection of brain function and audition of term small for gestational age infants （ TSGA） . Methods： The BAEPs of TSGA and term appropriate for gestational age infant （TAGA） were detected and compared. Results ： There was significant difference in the appearance rate of I waves, well - differentiation rate and peak latency of all waves, interphase peak latency of Ⅲ- Ⅴ waves and Ⅰ - Ⅴwaves, the wave amplitudes of Ⅰ and Ⅲ waves between TS- GA group and TAGA group （P 〈 0. 05） . Conclusion： BAEP is an effective method for early screening of auditory dysfunction and brainstern auditory centre abnormality in neonates and infants.
