通过瞬态诱发耳声发射 (TEOAE)和畸变产物耳声发射 (DPOAE) ,探讨其在黄疸新生儿听力筛选中的临床意义。应用Celesta 50 3型耳声发射仪对 1 1 5名黄疸新生儿及对照组正常足月新生儿 1 41名 (共 51 2耳 )进行TEOAE和DPOAE听力测定。结果 2 56名新生儿中有 64名双耳听力异常 ,其中正常新生儿占 1 8 44%(2 6/ 1 41 ) ,黄疸新生儿占 3 3 0 4%(3 8/ 1 1 5) ,p <0 0 1 ,有显著意义。生后 3月再次接受OAE复查 ,2例高胆红素患儿听力仍异常。新生儿高胆红素血症是听损伤的高危因素 ,应作听力随访。耳声发射是 1种快而有效的新生儿听力筛选方法之一。  相似文献

耳声发射在高危新生儿的应用探讨   总被引:1,自引:0,他引:1  
为探讨某些高危因素对新生儿听力的影响,尽早发现听力障碍,应用丹麦产Madsen Capeila耳声发射仪,对124名高危新生儿测试瞬态耳声发射(TEOAE)和畸变耳声发射(DPOAE),对其中一项不能通过者一月后复查,仍不能通过者3个月复查,如仍不能通过行OAE 脑干诱发电位(ABR)检查,明确听力障碍的原因并行干预治疗。结果显示:单耳TEOAE异常者28例次,DPOAE异常者33例次,双耳TEOAE异常者26例次,DPOAE异常者23例次。生后第一次查OAE124人,未能通过69人,生后一月复查65人,未能通过者26人;生后3个月复查,未能通过者2人,生后6个月复查,1人未通过,异常率0.8%,经ABR检查为单耳轻度听力损害。结论:(1)高危儿听力障碍的发生率为0.8%;(2)对第一次不能通过OAE的婴儿,尚不能断定为听力障碍,要定期复查和随访。(3)应对所有出生的新生儿都进行听力筛查,不能只限于高危儿。(4)对巨细胞病毒感染,生后虽OAE正常,但需进一步随访和复查。  相似文献

国外研究报道婴幼儿听力障碍发生率约为 0 .15 %~ 0 .6 % [1,2 ] ,在听力障碍高危儿中 ,发生率上升到 2 %~5 % [3 ] 。新生儿重症监护病房 (NICU)的新生儿是属于听力障碍高危儿。因此对NICU小儿进行听力筛选是早期发现先天性听力障碍的途径之一。Kemp[4 ] 在 1978年首次报道耳声发射以来 ,国外学者认为瞬态诱发耳声发射 (TEOAE)是一种快速、简单、客观、无创、有效评估新生儿听力的技术 ,是新生儿听力筛选的工具之一[5] 。本文目的是应用TEOAE对新生儿重症监护病儿进行听力测试。对象和方法本文作者曾在卢森堡国家…  相似文献

目的:耳声发射(OAE)和听觉脑干反应(ABR) 是新生儿听力筛查的常用方法。该研究旨在探讨畸变产物耳声发射(DPOAE) 和ABR应用于重症监护病房(NICU)高危新生儿听力筛查的差异和意义。方法:分别应用Smart-EP型听觉脑干诱发电位仪和Smart-OAE畸变产物耳声发射检查仪对600例(1 200耳)不同病因所致的高危儿同时进行DPOAE和ABR检查,将两种方法取得的检测结果进行比较。结果:在600例(1 200耳)高危新生儿中,ABR的异常率(78.6%,943/1 200耳)远高于DPOAE的未通过率(22.3%,268/1 200耳);二种检查的共同阴/阳性率分别为20.8%(241/1 200耳)和21%(252/1 200耳)。1 200耳中有493耳DPOAE和ABR的测试结果一致,占41.1%;707耳的测试结果不一致,占58.9%。DPOAE测试的假阳性率为6.0%(16/268耳),假阴性率为74.1%(691/932耳)。结论: DPOAE仅反映耳蜗功能,单独用于高危新生儿听功能筛查的价值有限。ABR检查果相对可靠,NICU高危新生儿听力筛查应先做ABR检查,ABR异常者再做OAE检查。ABR和OAE二种检测方法相互结合,方能提高高危新生儿听力筛查的准确性。  相似文献

正常幼儿畸变产物耳声发射听力筛查   总被引:2,自引:0,他引:2  
目的探讨畸变产物耳声发射(DPOAE)在幼儿听力筛查中的应用。方法应用DPOAE对100名幼儿园儿童(200耳)进行听力筛查,纯音对2、3、4 kHz 3个频率两次测试,耳声发射响应点在通过/转介线以上,信噪比>10 dB为筛查通过。结果94名儿童双耳通过筛查,4名儿童因耵聍栓塞双耳未通过筛查,取出耵聍后复筛通过;2名儿童单耳因分泌性中耳炎未通过筛查,治疗后复筛通过。结论DPOAE适用于幼儿听力筛查,建议将其列为每年的幼儿体检项目。  相似文献

目的探讨将听性脑干反应(ABR)和瞬态声诱发耳声发射(TEOAE)应用于高危新生儿听力损伤监测中的特点、差异和意义。方法分别应用MADSENCapella+型全功能耳声发射分析仪和MADSENERA2260型听性脑干反应仪对171例(342耳)不同病因导致的高危新生儿同时进行TEOAE和ABR测试,将2种测试方法进行比较。结果在171例(342耳)患儿中,TEOAE初筛通过率为66.96%(229/342耳),ABR通过率92.99%(318/342耳),两者共同阴性率为70.47%(241/342耳),TEOAE初筛的假阳性率为84.07%(95/113耳),假阴性率为2.62%(9/229耳)。结论ABR测试是可靠的新生儿听力筛查方法,TEOAE具有方便、客观、快速、无创等特点,为较好的新生儿听力筛查方法,但假阳性率高。二者需相互结合,相互补充。  相似文献

目的探讨听性脑干反应(ABR)和畸变产物耳声发射(DPOAE)应用于高胆红素血症新生儿听力筛查中的差异和意义。方法对197例诊断为高胆红素血症的新生儿同时进行ABR和DPOAE检查,异常者于生后3~4个月进行随访。结果 197例患儿临床上无明显胆红素脑病表现,ABR和DPOAE的总异常率分别为76.65%和14.47%;血清胆红素水平越高,ABR异常率越高(P<0.01),而DPOAE异常率与黄疸程度无明显相关性;DPOAE异常者多并存潜在的围生期其他导致听力损伤的高危因素。重度ABR异常者在生后3~4个月复查时仍有40.7%无改善。结论临床上无明显胆红素脑病表现的高胆红素血症新生儿ABR异常率高,对此类患儿进行听力检查应先ABR后DPOAE或者两者同时进行以避免漏诊。  相似文献

新生儿黄疸中碳氧血红蛋白检测的临床应用研究   总被引:4,自引:0,他引:4  
为探讨常见新生儿黄疸中碳氧血红蛋白(COHb)检测的临床价值,以德国800系列生化血气分析仪附加的270-血氧仪检测动脉化毛细血管血COHb,同步取静脉血检测血清总胆红素(STB)。病例选自本院新生儿病房2001年7月~2002年6月收治的伴有常见黄疸原因的足月新生儿157例[新生儿溶血病75例、感染51例、晚发性母乳性黄疸31例]。对照组101例为日龄匹配无病理性黄疸者,其中≤7天者52例,检测不同日龄的COHb,共测120例次。结果对照组中COHb生后5天内较高,峰值在1~2天,一周后接近成人正常水平。COHb与STB无相关性;溶血组COHb及STB均显著高于对照组(P<0.001),感染、母乳性黄疸组COHb与对照组比较差异无显著性(P>0.05)。结果提示COHb可用于证实新生儿黄疸中有无胆红素产量的增多,有助于黄疸病因的诊断。  相似文献

Abstract. Brodersen, R., Lakatos, L. and Karmazsin, L. (Institute of Medical Biochemistry, University of Aarhus, Denmark, and Pediatric Clinic, University Medical School, Debrecen, Hungary). D-penicillamine, a non-bilirubin-displacing drug in neonatal jaundice. Acta Paediatr Scand, 69:31, 1980.—D-penicillamine, a drug used clinically for the treatment of neonatal hyperbilirubinaemia, was tested for interference with the binding of bilirubin to human serum albumin by three methods: 1) The peroxidase technique, investigating the effect of D-penicillamine on the equilibrium concentration of unbound bilirubin in a solution containing a molar excess of albumin; 2) the MADDS method, measuring the concentration of vacant bilirubin binding site on albumin in a solution of pure albumin, or infant blood serum, with added D-penicillamine; and 3) injection of D-penicillamine into Gunn rats and determination of any decrease of plasma biiirubin which would be caused by displacement of the pigment. Results were negative in all cases. Quantitatively, the doses of D-penicillamine used clinically cannot displace bilirubin from its binding to albumin. The ameliorating effect on hyperbilirubinaemia in the newborn must be due to some other mechanism  相似文献

Seventy-four pregnant women were given 80 g of ethanol orally or 63, 94 or 102 g intravenously the day prior to delivery. Nineteen mothers and their offspring served as controls. The effect on the bilirubin values of the newborn was studied. The bilirubin levels of the newborn were not significantly lower during the first six days of life compared with the controls. The results differ from those reported earlier. The reasons for this are discussed.  相似文献

Undoubtedly much of the morbidity and mortality associated with neonatal meningitis is related to delay in diagnosis. Undoubtedly also, organisms such as proteus and pyocyaneus are more lethal. Despite this, there is adequate evidence that electrolyte imbalance from inappropriate A.D.H. secretion can compound the problems of the meningitis and thus disturb cerebral function. Careful monitoring of the serum sodium and also appropriate fluid restriction will prevent this. In addition, there should be an awareness of the frequency of ventriculitis in this age group. Ventriculitis can only be effectively managed by the local instillation of chemotherapeutic agents and a Rickham reservoir is a most satisfactory means of accomplishing this end.  相似文献

Abstract. Nordshus, T. and Monn, E. (Department of Radiology, Section of Paediatric Radiology and Department of Paediatrics, Rikshospitalet, The National Hospital, University of Oslo, Oslo, Norway). Ultrasonography in the diagnosis of neonatal adrenal haemorrhage. Acta Paediatr Scand 69: 695, 1980.—Two cases of neonates with adrenal haemorrhage are presented. The clinical, radiological and ultrasonographical signs are described. The future role of echography as compared to other radiological procedures, including computerized tomography, is discussed. Ultrasonography is recommended as a screening method, and is well suited for assessing the size and internal structure of pathological processes.  相似文献

Glucose-6-phosphate dehydrogenase (G6PD) deficiency can lead to acute hemolytic anemia, chronic nonspherocytic hemolytic anemia, and neonatal jaundice. Neonatal red cell pyruvate kinase (PK) deficiency may cause clinical patterns, ranging from extremely severe hemolytic anemia to moderate jaundice. The authors aimed at studying the prevalence of G6PD and PK deficiency among Egyptian neonates with pathological indirect hyperbilirubinemia in Cairo. This case-series study included 69 newborns with unconjugated hyperbilirubinemia. All were subjected to clinical history, laboratory investigations, e.g., complete blood counts, reticulocytic counts, direct and indirect serum bilirubin levels, Coombs tests, qualitative assay of G6PD activity by methemoglobin reduction test, and measurement of erythrocytic PK levels. The study detected 10 neonates with G6PD deficiency, which means that the prevalence of G6PD deficiency among Egyptian neonates with hyperbilirubinemia is 14.4% (21.2% of males). G6PD deficiency was significantly higher in males than females (P = .01). The authors detected 2 cases with PK deficiency, making the prevalence of its deficiency 2.8%. These data demonstrate that G6PD deficiency is an important cause for neonatal jaundice in Egyptians. Neonatal screening for its deficiency is recommended. PK deficiency is not a common cause of neonatal jaundice. However, this needs further investigation on a larger scale.  相似文献
