Brainstem auditory evoked potentials in patients with delayed encephalopathy after acute carbon monoxide poisoning

Objective:To evaluate the changes of brainstem auditory evoked potential (BAEP) in patients with delayed encephalopathy after acute carbon monoxide poisoning. Methods: BAEPs were performed in 32 controls and 40 patients. Wave Ⅰ , Ⅱ , Ⅲ ,Ⅳ, Ⅴ latencies and Ⅰ-Ⅲ , Ⅲ-Ⅴ , Ⅰ-Ⅴ interpeak latencies were measured, respectively. Results: Abnormalities of BAEPs in 13 patients (13/40, 32 ％). Among the13 abnormal BAEPs, 3 displayed prolongation of latency to waves in one side, no potential in another side; 5 displayed a similar abnormality which was bilateral prolongation of latency to waves ;and another 5 displayed unilateral latency delay. Compared wave Ⅰ , Ⅱ , Ⅲ , Ⅳ, Ⅴ latencies and Ⅰ-Ⅲ , Ⅲ-Ⅴ , Ⅰ-Ⅴ interpeak latencies in the patients and the controls, there were no significant differences (P＞0.05). Conclusion: BAEPs can be used for evaluating the diagnostic and prognostic values in the cases of delayed encephalopathy after acute carbon monoxide poisoning.

Characteristics of brainstem auditory evoked potentials of students studying folk dance

BACKGROUND： Previous experiments have demonstrated that brainstem auditory evoked potential is affected by exercise, exercise duration, and frequency. OBJECTIVE： Comparing the brainstem auditory evoked potential of students studying folk dance to students studying other subjects. DESIGN： Observational contrast study. SETTING： Physical Education College, Shandong Normal University PARTICIPANTS： Fifty-five female students were enrolled at Shandong Normal University between September and December in 2005, including 21 students that studied folk dance and 34 students that studied other subjects. The age of the folk dance students averaged （19 ± 1） years and dance training length was （6.0 ± 1.5） years. The students that studied other subjects had never taken part in dance training or other physical training, and their age averaged （22 ± 1） years, body height averaged （162 ± 5） cm, body mass averaged （51 ± 6） kg. All subjects had no prior ear disease or history of other neurological disorders. All students provided informed consent for the experimental project. METHODS： The neural electricity tester, NDI-200 （Shanghai Poseidon Medical Electronic Instrument Factory） was used to examine and record Brainstem Auditory Evoked Potential values of the subjects during silence, as well as to transversally analyze the Brainstem Auditory Evoked Potential values. The electrode positions were cleaned and degreased with soapy water, followed by ethanol. The selected bipolar electrodes were situated on the head： recording electrodes were placed at the Baihui acupoint, and the reference electrode was placed at the mastoid of the measured ear, with grounding electrodes in the center of the forehead. Brainstem Auditory Evoked Potential values were elicited by monaural stimulation of a ＂click＂ though an earphone; the other ear was sheltered by the white noise. The click intensity was 102 db, the stimulation frequency was 30 Hz, the bandpass filters were 1 000-3 000 Hz, the sensitivity was 5 ta V, and a total of 2 000 sweeps were averaged. Waveform identification and analysis： various components of the Brainstem Auditory Evoked Potential values were identified, and the peak latencies and peak-peak values were analyzed. MAIN OUTCOME MEASURES： Latency of Ⅰ , Ⅱ, Ⅲ, Ⅳ, Ⅴ and Peak-Peak Value of Ⅰ, Ⅲ, Ⅴwere measured. RESULTS： Fifty-five subjects were enrolled in the final analysis, without any loss. Compared to the students who studied other subjects ① Ⅰ -Ⅴ peak latencies （PL）： Ⅳ PL of the right ear of the folk dance students was obviously longer （P 〈 0.05）; ② Ⅰ, Ⅲ, V peak-peak values：Ⅰ peak-peak values of the right ear were obviously higher （P 〈 0.05）. CONCUSION： ① PL of the right ear of the folk dance students was obviously longer, which indicates that dancing results in a stronger sensibility to auditory stimuli. ②. Peak-peak values were obviously higher, which indicates that long-term exercise enhances the music senses and synchrony of auditory nerve impulses.

Characteristics of brainstem auditory evoked potential of neonates with mild or moderate hyperbilirubinemia

BACKGROUND： Brainstem auditory evoked potential （BAEP） has been widely used to evaluate the functional integrity and development of injured auditory system and brain, especially to objectively evaluate the function of auditory system and brain stem of very young babies, such as neonates and sick babies. OBJECTIVE： To observe the changes of BAEP of neonates with hyperbilirubinemia, and to investigate the relationship of bilirubin concentration and BAEP. DESIGN： An observation experiment. SETTING： Department of Pediatrics, the 309 Clinical Division, General Hospital of Chinese PLA. PARTICIPANTS： Fifty-eight neonates with mild or moderate hyperbilirubinemia exhibiting jaundice within 24 hours after born, who received the treatment in the Department of Pediatrics, the 309 Clinical Division, General Hospital of Chinese PLA between January 2004 and May 2007, were recruited in this study. The involved neonates, 31 boys and 27 girls, had gestational age of 37 to 46 weeks. They had no history of birth asphyxia, and were scored 8 to 10 points when born. Written informed consents of examination and treatment were obtained from the guardians of the neonates. This study was approved by the Hospital Ethics Committee. According to serum total bilirubin value, the neonates were assigned into 3 groups： low-concentration bilirubin group （n =16）, moderate-concentration bilirubin group （n =27） and high-concentration bilirubin group （n =15）. According to mean daily bilirubin increase, the subjects were sub-assigned into bilirubin rapid increase group （n =39） and bilirubin slow increase group （n = 19）. METHODS： After admission, all the neonates received drug treatment. Meanwhile, their 116 ears were examined with a myoelectricity evoked potential equipment （KEYPOINT） in latency, wave duration, amplitude and wave shape differentiation of each wave of BAEP. BAEP abnormal type was observed and abnormal rate of BAEP was calculated. MAIN OUTCOME MEASURES： ①Abnormal rate and abnormal type of BAEP. ② Latency of waves Ⅰ , Ⅲ and Ⅴ, and wave duration of waves Ⅰ to Ⅲ,Ⅲ to Ⅴ, and Ⅰ to Ⅴ. RESULTS： Fifty-eight neonates with mild or moderate hyperbilirubinemia were involved in the final analysis. ①Abnormal type and abnormal rate of BAEP of neonates with hyperbilirubinemia： Among the 116 ears, unilateral or bilateral waves Ⅰ, Ⅲ,Ⅴ still existed. The latency of waves Ⅰ, Ⅲ and Ⅴ was ＋2.5 s longer than the normal level in 8, 4 and 15 ears, respectively. The wave duration of waves Ⅰ to Ⅲ and waves Ⅲ to Ⅴ was ＋2.5 s longer than the normal level in 6 and 14 ears, respectively. The wave duration of waves Ⅲ to Ⅴ was longer than that of ipsilateral waves Ⅰ to Ⅲ in 24 ears. The latency difference of wave Ⅴ between two ears was larger than 0.4 ms in 31 neonates with hyperbilirubinemia; The amplitude of wave Ⅴ to that of ipsilateral wave 1 was lower than 0.5 in 29 neonates. Totally 52 ears were abnormal, and the abnormal rate was 44.8%. One to two months later, 98% abnormal neonates with hyperbilirubinemia recovered. The abnormal rate in the low-, moderate-, and high-concentration bilirubin groups was 37.5%, 44.4% and 53.3%, respectively. ② Comparison of latency and wave duration of each wave of BAEP： Latency of waves Ⅰ, Ⅲ and Ⅴ, and wave duration of waves Ⅰ to III and Ⅲ to Ⅴ were gradually prolonged in low-, moderate-, and high-concentration bilirubin groups, but significant difference did not exist between two groups （P 〉 0.05）. ③ There were no significant differences in latency of waves Ⅰ, Ⅲand Ⅴ, and wave duration of waves Ⅰ to Ⅲ, Ⅲto Ⅴ and Ⅰ to Ⅴ between bilirubin rapid increase group and bilirubin slow increase group （P 〉 0.05）. CONCLUSION： Auditory acuity and brainstem of neonates with mild or moderate hyperbilirubinemia are damaged to some extent. High-concentration bilirubin causes BAEP abnormality easily. Bilirubin increase and its concentration change are not consistent with nervous lesion degree.

Electroencephalogram and brainstem auditory evoked potential in 539 patients with central coordination disorder

BACKGROUND： Electroencephalogram （EEG） and brainstem auditory evoked potential （BAEP） are objective non-invasive means of measuring brain electrophysiology. OBJECTIVE： To analyze the value of EEG and BAEP in early diagnosis, treatment and prognostic evaluation of central coordination disorder. DESIGN, TIME AND SETTING： This case analysis study was performed at the Rehabilitation Center of Hunan Children＇s Hospital from January 2002 to January 2006. PARTICIPANTS： A total of 593 patients with severe central coordination disorder, comprising 455 boys and 138 girls, aged 1-6 months were enrolled for this study. METHODS： EEG was monitored using electroencephalography. BAEP was recorded using a Keypoint electromyogram device. Intelligence was tested by professionals using the Gesell scale. MAIN OUTCOME MEASURES： （1） The rate of abnormal EEG and BAEP, （2） correlation of abnormalities of EEG and BAEP with associated injuries, （3） correlation of abnormalities of EEG and BAEP with high risk factors. RESULTS： The rate of abnormal EEG was 68.6% （407/593 patients）, and was increased in patients who also had mental retardation （P 〈 0.05）. The rate of abnormal BAEP was 21.4% （127/593 patients）. These 127 patients included 67 patients （52.8%） with peripheral auditory damage and 60 patients （47.2%） with central and mixed auditory damage. The rate of abnormal BAEP was significantly increased in patients who also had mental retardation （P 〈 0.01 ）. Logistic regression analysis showed that asphyxia （P 〈 0.05）, jaundice, preterm delivery, low birth weight and the umbilical cord around the neck were closely correlated with abnormal EEG in patients with central coordination disorder, lntracranial hemorrhage, jaundice （P 〈 0.05）, low birth weight and intrauterine infection （P 〈 0.05） were closely correlated with abnormal BAEP in patients with central coordination disorder. CONCLUSION： Central coordination disorder is often associated with abnormal EEG and BAEP. The rate of EEG or BAEP abnormality is positively associated with the size of the brain injury. Asphyxia is a high risk factor for abnormal EEG in central coordination disorder. Jaundice and intrauterine infection are high risk factors for abnormal BAEP in central coordination disorder.

Otoacoustic Emissions and Evoked Potentials in Infants after Breast-Feeding Jaundice——Hearing Dysfunction in Breast-Feeding Jaundice

We study hearing in a group of infants with Breast-feeding jaundice (BFJ) by means of Transient-evoked otoacoustic emissions (T-EOE) and Brainstem auditory evoked potentials (BAEP) searching for relationship between bilirubin serum levels and auditory dysfunction. Eleven infants born at-term with BFJ were selected for the study. We studied also 11 control age- and gender matched healthy at-term infants without signs of jaundice. T-EOAE studies were performed between 5-7 days after birth, and 3 months later. BAEP studies were performed once. BFJ group infants exhibited lower amplitudes in T-EOE than infants in the control group. These differences disappear at the 3-month evaluation. In BAEP, we observed a significant latency delay of waves I and V in Breast-feeding jaundice group infants. All infants in both groups demonstrated reproducible wave V response at 30 decibels. No significant correlation values were observed between bilirubin serum levels and T-EOE and BAEP variables. Our data suggest that BFJ can result in transient peripheral and central auditory dysfunction. Dysfunction is reversible after treatment of infants with BFJ.

RELATIONS OF INTRACRANIAL PRESSURE, CREATINE KINASE AND BRAINSTEM AUDITORY EVOKED POTENTIAL IN PATIENTS WITH TRAUMATIC BRAIN EDEMA

We studied the relations of intracranial pressure (ICP),creatine kinase (CK) and bralnstem auditory evoked potential (BAEP) in 44 patients with traumatic brain edema who were admitted to our hospital from June 1990 to February 1991. There were 30 males and 14 females, with age range from 9 to 67 years. The results showed that the abnormal BAEP could reflect the severity of cerebral edema in acute head injury and was related to ICP and serum CK levels. When ICP>30 mmHg (4kPa), the abnormality of BAEP was more obvious than that of the control group (P<0.05); the serum CK levels were also elevated markedly. In patients with ICP over and below 4kPa, the rate of abnormal BAEP was 38.46% and 77.78% respectively (P<0.05). The serum CK level in the normal group or in the group with moderate abnormality of BAEP was significantly different from that in the group with severe abnormality or lack of BAEP (274.8± 98.24 U/L vs 705.3± 364.27 U/L; P<0.001). After treatment, the ICP returned to normal, and the BAEP norm

The effect of lead on brainstem auditory evoked potentials in children

To determine whether lead affects brainstem auditory evoked potentials (BAEPs) in low-to-moderate lead exposed children Methods BAEPs were recorded from 114 asymptomatic children aged 1-6 years Average values were calculated for peak latency (PL) and amplitude (Amp) Whole blood lead (PbB) levels were assessed by graphite furnace atomic absorption spectroscopy Based on their PbB levels, subjects were divided into low lead (PbB<100 μg/L) and high lead subgroups (PbB ≥100 μg/L) Results The PbB levels of the 114 subjects ranged from 32 0 to 380 0 μg/L in a positively skewed distribution The median of PbB levels was 90 0 μg/L while the arithmetic average was 88 0 μg/L Of the subjects, 43 0% (49/114) had levels equal to or greater than 100 μg/L Bilateral PLs Ⅰ, Ⅴ, and Ⅲ of the left ear in the high lead subgroup were significantly longer than those in the low lead subgroup (P<0 05) A positive correlation was found between PbB levels and bilateral PLs Ⅰ, Ⅴ and Ⅲ of the left ear (P<0 05), after controlling for age and gender as confounding factors A significant and positive correlation between PbB levels and PL Ⅰ of the left ear, even when PbB levels were lower than 100 μg/L, in the low subgroup (r=0 295, P=0 019) was also found Conclusions Lead poisoning in children younger than 6 years old is a very serious problem to which close attention should be paid The indications that lead prolongs partial PLs may imply that lead, even at PbB levels lower than 100 μg/L, impairs both the peripheral and the central portions of the auditory system BAEPs may be a sensitive detector of subclinical lead exposure effects on the nervous system in children

Brainstem auditory evoked potential combined with high resolution cranial base CT can optimize the diagnosis of auditory nerve injury

Purpose:Auditory nerve injury is one of the most common nerve injury complications of skull base fractures.However,there is currently a lack of auxiliary examination methods for its direct diagnosis.The purpose of this study was to find a more efficient and accurate means of diagnosis for auditory nerve injury.Methods:Through retrospectively analyzing the results of brainstem auditory evoked potential(BAEP)and high-resolution CT(HRCT)in 37 patients with hearing impairment following trauma from January 1,2018 to July 31,2020,the role of the two inspection methods in the diagnosis of auditory nerve injury was studied.Inclusion criteria were patient had a clear history of trauma and unilateral hearing impairment after trauma;while exclusion criteria were:(1)severe patient with a Glasgow coma scale score<5 because these patients were classified as severe head injury and admitted to the intensive care unit,(2)patient in the subacute stage admitted 72 h after trauma,and(3)patient with prior hearing impairment before trauma.According to Goodman's classification of hearing impairment,the patients were divided into low/medium/severe injury groups.In addition,patients were divided into HRCT-positive and negative groups for further investigation with their BAEP results.The positive rates of BEAP for each group were observed,and the results were analyzed by Chi-square test(p<0.05,regarded as statistical difference).Results:A total of 37 patients were included,including 21 males and 16 females.All of them were hospitalized patients with GCS score of 6-15 at the time of admission.The BAEP positive rate in the medium and severe injury group was 100%,which was significantly higher than that in the low injury group(27.27%)(p<0.01).The rate of BEAP positivity was significantly higher in the HRCT-positive group(20/30,66.7%)than in the HRCT-negative group(1/7,14.3%)(p<0.05).Twenty patients(54.05%)were both positive for BEAP and HRCT test,and considered to have auditory nerve damage.Six patients(16.22%)were both negative for BEAP and HRCT test,and 10 patients(27.03%)were BAEP-negative but HRCT-positive:all the 16 patients were considered as non-neurological injury.The rest 1 case(2.70%)was BAEP-positive but HRCT-negative,which we speculate may have auditory nerve concussion.Conclusion:By way of BAEP combining with skull base HRCT,we may improve the accuracy of the diagnosis of auditory nerve injury.Such a diagnostic strategy may be beneficial to guiding treatment plans and evaluating prognosis.

Dysfunction of the peripheral and central auditory pathway in patients with type 1 diabetes mellitus

Although auditory alterations are not a typical symptom of diabetes mellitus (DM), they can occur in patients with type 1 DM. The findings of previous studies are controversial, because the frequency and degree of hearing loss varies, and quite often alterations are still subclinical. The typical test used to detect and manage hearing loss is the audiogram, but this test alone is only capable of detecting alterations due to injury of the inner hair cells and/or alterations in the central auditory pathway. However, auditory alterations resulting from a dysfunction that is still subclinical are only able to be detected through electrophysiological auditory tests, such as the otoacoustic emissions (OAE) and the auditory brainstem response (ABR) tests. Thus, the purpose of this paper is to review the studies that utilize the OAE and ABR tests, and to verify if the dysfunction is cochlear and/or neural in patients with type 1 DM. The findings of this review demonstrate that patients with type 1 DM can have auditory alterations stemming from a central cochlear origin. Following this finding, early diagnosis is very important in order to implement preventative treatments and initiate therapy.

The needles were retained for 30 min. Acupuncture treatment was given once every two days, three treatments a week. The brainstem auditory evoked potential （BAEP） and visual evoked potential （VEP） were observed in 6 weeks of treatment. The change in Hamilton depression scale （HAMD） score was observed before and after treatment in the depression group. Results After treatment, VEP wave latency was shortened significantly in patients of depression （P〈0.05）, BAEPIII wave latency was shortened significantly （P〈0.05）. The score of HAMD was decreased apparently in the depression group （P〈0.05）. Conclusions The stressability of visual and auditory stimuli in the central nervous system was decreased in the patients of depression. Acupuncture shortens remarkably the brainstem evoked potentials latency in the patients of depression and achieves the effective results in the treatment of primary depression.

目的 探究脑梗死继发癫痫患者脑干听觉诱发电位(brainstem auditory e-voked potential,BAEP)与脑血流量(cerebral blood flow,CBF)相关性及意义。方法 选取脑梗死继发癫痫患者80例作为研究组,另选同期脑梗死未继发癫痫患者80例作为对照组。比较2组入院时一般资料、CBF、血清脂蛋白相关磷脂酶A2(lipoprotein-associated phospholipase A2,Lp-PLA2)、神经元烯醇化酶(neuronal-specific enolase,NSE)水平及BAEP评分,分析脑梗死继发癫痫患者BAEP评分与CBF、血清Lp-PLA2、NSE水平的相关性,并比较研究组不同癫痫特征(发作类型、放电类型、放电部位)患者BAEP评分,分析BAEP评分与脑梗死继发癫痫发作特征的相关性,通过受试者工作特征(receiver operating characteristic,ROC)曲线分析BAEP评分、CBF、Lp-PLA2、NSE预测脑梗死继发癫痫的价值。结果 研究组CBF低于对照组,血清Lp-PLA2、NSE水平及BAEP评分均高于对照组(P<0.05);研究组BAEP评分与CBF呈负相关,与血清Lp-PLA2、NSE水平呈正相关(P<0.05);研究组癫痫全面发作患者BAEP评分高于部分发作患者,多灶性放电患者BAEP评分高于局灶性放电患者(P<0.05);BAEP评分与脑梗死继发癫痫发作类型、放电类型呈正相关(P<0.05);BAEP评分、CBF、Lp-PLA2、NSE预测脑梗死继发癫痫的曲线下面积(area under the curve,AUC)均>0.7,其中BAEP评分联合CBF、Lp-PLA2、NSE预测的AUC最大,为0.928(95%CI:0.876~0.963)。结论 脑梗死继发癫痫患者BAEP与CBF及血清Lp-PLA2、NSE水平密切相关,各指标联合在预测脑梗死继发癫痫方面具有较高预测效能。

重复经颅磁刺激结合舌压抗阻反馈训练对脑出血术后吞咽功能障碍患者脑干听觉诱发电位及误吸风险的影响

目的探讨重复经颅磁刺激结合舌压抗阻反馈训练在脑出血术后吞咽功能障碍患者中的应用效果。方法选择2019年7月至2021年8月我院收治的80例脑出血术后吞咽功能障碍患者,根据干预方案不同将其分为对照组、观察组,各40例。对照组接受舌压抗阻反馈训练,观察组在对照组干预方案基础上加施重复经颅磁刺激。比较两组的干预效果。结果干预后,观察组的脑干听觉诱发电位(BAEP)Ⅰ波、Ⅲ波、Ⅴ波潜伏期均短于对照组(P<0.05)。干预后,观察组的渗透-误吸量表(PAS)等级分布优于对照组(P<0.05)。干预后,观察组的功能性经口摄食量表(FOIS)评分高于对照组,标准吞咽功能评估量表(SSA)评分低于对照组(P<0.05)。结论重复经颅磁刺激结合舌压抗阻反馈训练可改善脑出血术后吞咽功能障碍患者BAEP及吞咽功能,减少误吸的发生风险。
