Objective To investigate the application of butterfly-like transparent dressing in tracheotomy.Methods 62 cases of patients treated with tracheotomy for acute respiratory failure were adopted in this study and divided into the observation group(32 cases)and the control group(30 cases).The observation group WaS covered with butterfly-like transparent dressing and the control group Was covered with common adhesive plaster.Noninvasive ventilation after withdrawal of endotracheal intubation calmula,tolerance,reaction of local skin and mean time of concrescence were observed.Results The observation group showed greater tolerance,lesser local adverse reaction and shorter mean time of concrescence than those of the control group.Conclu-sion Butterfly-like transparent dressingis a kind of good dressing for incision of trachcotomy.
