Mid-latency auditory evoked potentials during ketamine anaesthesia in humans.
We studied mid-latency auditory evoked potentials (MLAEP) during induction of general anaesthesia with ketamine 2 mg kg-1. MLAEP were recorded before, during and after induction of general anaesthesia on the vertex (positive) and mastoid (negative) positions. Latencies of the peak V, Na, Pa, Nb, P1 and amplitudes Na/Pa, Pa/Nb and Nb/P1 were measured. Fast-Fourier transformation was used to calc...
متن کاملEffects of increasing doses of alfentanil, fentanyl and morphine on mid-latency auditory evoked potentials.
We have studied dose-dependent effects of alfentanil, fentanyl and morphine on mid-latency auditory evoked potentials (MLAEP). Anaesthesia was induced with alfentanil 100 micrograms kg-1 every 5 min to a total dose of 500 micrograms kg-1 (group I, n = 10), fentanyl 10 micrograms kg-1 every 7 min to a total dose of 50 micrograms kg-1 (group II, n = 10) or morphine 1 mg kg-1 for induction and 0.5...
متن کاملImpact of propofol on mid-latency auditory-evoked potentials in children.
BACKGROUND Propofol is increasingly used in paediatric anaesthesia, but can be challenging to titrate accurately in this group. Mid-latency auditory-evoked potentials (MLAEPs) can be used to help titrate propofol. However, the effects of propofol on MLAEP in children are unclear. Therefore, we investigated the relationship between propofol and MLAEP in children undergoing anaesthesia. METHODS...
متن کاملMid-latency auditory evoked potentials and circulatory response to loud sounds.
We investigated in 60 patients scheduled for elective aorto-coronary bypass grafting if loud sounds by themselves can induce cardiovascular responses and if these could be related to mid-latency auditory evoked potentials (MLAEP). Anaesthesia was induced in group I (n = 20) with flunitrazepam-fentanyl 0.01 mg kg-1 and maintained with flunitrazepam-fentanyl 1.2 mg h-1. Patients in groups II (n =...
متن کاملEarly, Mid, and Late-Latency Auditory Evoked Potentials During Pregnancy: Two Cases
Objective: There are various known hormone-related effects on audiometric thresholds and other auditory measures; however, research is scarce and mixed on the effect of pregnancy on the early-, mid-, and late-latency auditory evoked responses in a longitudinal fashion. Of clinical importance is to know whether electrophysiologic measures during pregnancy may further alter the results of, or mas...
