Randomized Controlled Trial Comparative StudyMastery of pMDI technique, asthma control and quality-of-life of children with asthma: A randomized controlled study comparing two inhaler technique training approaches.
Verbal counselling (VC) is the clinical standard for training patients on correct inhaler use. Patients fail to recall their VC with time. Ethical approval was obtained to compare the pressurized metered dose inhaler (pMDI) VC with Trainhaler (TH), a novel pMDI inhalation flow and technique training device, in children with asthma. ⋯ The TH improved the inhalation flow through the pMDI close to the ideal needed for adequate lung deposition. Both methods equally enhanced the children's mastery of pMDI use. This was reflected on better AC and QoL. Accessibility to TH might help maintaining the good inhaler use and decreasing regular VC.
