Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The goal is to evaluate the quality of the Auditory Brainstem Response (ABR) test in the same enrolled participant under two different anesthetic techniques, verifying the presence or absence of auditory responses in each technique. This stage will be selected through the review of ABR tests with click-type stimulation by a group of speech-language pathologists blinded to the anesthetic technique used. The evaluators will independently analyze the recordings obtained under each anesthetic technique. For each ear and for each stimulus intensity level, the presence or absence of an auditory response in the test tracing will be observed. The results will be presented as the number and percentage of detectable responses in each anesthetic technique. Participants will be monitored during the test and post-anesthetic recovery, which will last approximately 60 to 90 minutes. | — |
