We studied auditory brainstem responses (ABR) in 50 comatous patients (610 recordings). Findings of ABRs were classified in four groups and the results were as follows:
1. Normal responses (20 patients, 3 of them died (15%))
2. Decrease in amplitude (8 patients, 3 of them died (38%))
3. Prolongation of latency of the later components (5 patients, 3 of them died (60%))
4. Absence of the responses or recognition of only an early component (17 patients, 16 of them died (94%)).
Our findings suggest that ABR is a reliable diagnostic tool for predicting the outcome of comatous patients.
