自临床应用胎儿声振刺激(FAS)试验以来,许多学者都很关心该试验对胎儿是否有不利影响。因此推荐应用都很慎重。近年研究发现声振试验在子宫上的声压较高,故当该试验广泛应用于临床时,是否对胎儿有远期影响,还应进一步研究。为评估受试的幼儿情况,调查研究了1985～1987年接受过该试验的妊娠妇女460例。共有幼儿525例,其中41例地址不详,6例死亡,可供随访研究的478例。在幼儿4岁时深入随访其父母以了解其全面发育情况,并进行全面体格检查,如听力、视力及运动等检测。检测结果:478例中有450例听力和发育正常,13例拒绝作听力试验,但其发育正常,言语也 Since the clinical application of the FAS test, many scholars have been very concerned about whether this test has adverse effects on the fetus. Therefore, recommended applications are very cautious. In recent years, studies have found that the sound pressure test in the womb higher sound pressure, so when the trial is widely used in clinical, whether the fetus have a long-term impact, but also further study. To assess the condition of the children under study, 460 pregnant women who had undergone the trial between 1985 and 1987 were investigated. A total of 525 children were enrolled, of whom 41 were unknown, 6 died and 478 were available for follow-up studies. At the age of 4, infants and young children are followed up with their parents for further information on their overall development and to undergo a full physical examination such as hearing, vision and exercise tests. Test results: 450 cases of 478 cases of normal hearing and development, 13 refused to make a hearing test, but its normal development, speech is also
