RESUMO
This article discusses the place of routine use of depth of anaesthesia monitoring in patients receiving volatile anaesthesia. Benefits include reducing the probability of accidental awareness or excessive depth of anaesthesia, and creating training opportunities to improve familiarity with its use, but these must be weighed against the costs, as it may not be advantageous from a cost-benefit perspective.

OBJECT: To evaluate the hearing of infants with history of neonatal hyperbilirubinemia using ABR. METHODS: A prospective randomized study carried on 100 infants whose hearing was assessed by ABR. Infants were allocated into two groups; case group which involve 60 infants with history of neonatal hyperbilirubinemia (bilirubin more than17 mg/dl and less than 30 mg/dl) and control group involve 40 healthy infants. Each group was divided into 3 groups based on their age i.e. ≤ 6 months, > 6-9 months &> 9-12 months. The evaluated variables were latency time & inter peak latency time. RESULTS: The mean latencies of wave III&V of ABR were significantly higher in the case group compared with the controls (P < 0.001) while the mean latencies of wave I did not show a significant difference between the two study groups (P > 0.05). The mean inter wave latencies I-III, I-V& III-V of ABR were significantly higher in the case group compared with the controls. There was a negative correlation between age and the studied variables. CONCLUSION: Hyperbilirubinemia have an adverse effect on neonatal hearing which was reflected by ABR parameters of this study.
