An author's error occurred in this editorial by Hans Bisgaard (12 October 1996, pp 895-6). The fourth sentence in the third paragraph should have read: “During simulated breathing by a ventilator, the relative fine particle masses delivered by a pressurised metered dose inhaler plus a NebuChamber spacer (budesonide), an inhaler plus Babyhaler (fluticasone), and an inhaler plus AeroChamber (budesonide) were 2.5, 1.5, and 1 [not 1, 1.5, and 2.5] respectively.” The conclusion drawn in the editorial is correct–that is, “that the nominal dose for an inhaler plus AeroChamber should be 2.5 times higher than that for an inhaler plus NebuChamber to obtain the same clinical effect.”
