A case report of soda-lime dust contamination of the breathing circuit of an anesthesia machine causing bronchospasm in a patient is presented. Various factors in absorber design and increased dusting of soda lime due to high-flow techniques and lack of wetting are described. A modification of the Fraser-Sweatman absorber leading the fresh gas into an area free of dust accumulation has resulted in near-complete elimination of the problem.
