[Results of ERA-hearing-tests during infancy (author's transl)]
Insights
This study evaluated 50 children with hearing loss. Haloperidol sedation facilitated auditory evoked potential (AEP) testing, aiding in diagnosis and hearing level determination for improved pediatric audiological assessments.
Area of Science:
- Audiology and Neurophysiology
- Pediatric Medicine
Context:
- Evaluating diagnostic methods for pediatric hearing loss.
- Assessing the efficacy of pharmacological agents in audiological assessments.
Purpose:
- To evaluate the results of 50 children with partial or complex hearing loss.
- To assess the impact of Haloperidol on auditory evoked potentials (AEPs) for diagnosis.
- To compare different methods for determining hearing levels in children.
Summary:
- Haloperidol (0.1 mg/kg) administered orally induced sedation suitable for audiological testing in children.
- Auditory evoked potential (AEP) testing revealed dominant N2 and P3 components under Haloperidol sedation.
- Hearing levels were identified using input/output functions (24%), summation curves (26%), and Biesalski's method (30%).
- Deafness was suspected in 20% of cases with undetectable AEPs, with average hearing loss ranging from 55-70 dB.
Impact:
- Haloperidol provides a viable sedation option for pediatric audiological evaluations, particularly when natural sleep is not feasible.
- The study highlights the challenges and varying success rates of different AEP analysis techniques in diagnosing hearing loss in children.
- Findings contribute to refining diagnostic protocols for pediatric hearing impairment, potentially leading to earlier interventions.
Abstract:
The results of 50 children with partial or complex hearing loss, referred to the hospital for diagnosis, were evaluated according to different aspects. Haloperidol (0,1 mg/kg) administered orally causes potential changes similar to those known in the literature for natural sleep and chloral hydrate sleep (Freigang and Kevanishvili 1975). The components N2 and P3 are dominant in the potential picture instead of N1 and P2. Regarding sedation, the drug meets all requirements. The identification of the hearing level by means of the input/output functions could be performed in 24 per cent of all cases, whereas summation curves must be employed in 26 per cent and threshold determinations according to Biesalski in 30 per cent. Deafness is assumed in 20 per cent of the patients with nondetectable AEP. The average hearing loss evaluated according to age groups is between 55 and 70 dB.
