Abstract

Auditory evoked response (AER) was recorded before, during and after physiotherapy in 11 paralysed (atracurium 0.56 (SD) 0.13 mg kg^-1 h^-1), sedated (propofol 2.2 (1.0) mg kg^-1 h^-1; fentanyl 4.4 (2.3) μg kg^-1 h^-1) and critically ill patients undergoing ventilation in the intensive care unit (ICU). The latency of the negative wave, N_B, was reduced by physiotherapy (mean 44.8 (SD) 7.9 ms before, 41.0 (6.8) ms during (P < 0.01, non-parametric Friedman test) and 45.6 (6.3) ms after physiotherapy) ;N_B amplitude showed no consistent change (-0.81 (1.4) μV, -0.81 (1.5) μV and - 0.71 (1.3) μV, respectively). N_B latency responded to patient arousal at constant levels of sedation and this requires further evaluation as a means of monitoring sedation in paralysed patients in the ICU.
