Abstract
We experienced a patient who had lost the response to ABR stimulation after weaning from mechanical ventilation. The child had been treated with mechanical ventilation from four months through one month and one year of age and had received pancuronium bromide (PB) during mechanical ventilation. Five children with severe deafness having received PB similar to the patient visited our department. All six cases were affected with tracheomalacia and were given PB consecutively for five to ten months. Our findings obtained from the six young patients suggest a strong correlation between long-term administration of pancuronium bromide and the development of deafness.
