Importance of training for correct Turbuhaler use in preschool children

Acta Paediatr. 1998 Aug;87(8):842-7. doi: 10.1080/080352598750013608.


Aim: To study the impact of both audiovisual information and nurse-training on the use of budesonide Turbuhaler in preschool children who had never used a dry powder inhaler.

Design: A single-blind, randomized, parallel-group trial studied 72 children aged 3-5 y. All children and their parents were shown an instructional video and given written instruction. After this, peak inspiratory flow (PIF1) through Turbuhaler was measured. Children in group A (n = 36) then received individual training by a nurse while those in Group B (n = 36) did not and PIF2 was measured. Afterwards, Group B received similar individual training while Group A received no additional training, and PIF3 was measured. Group A was given a placebo Turbuhaler and encouraged to practice at home. Two weeks later, both groups returned to the clinic where PIF4 was measured.

Results: The number of children who were able to correctly perform PIF1, PIF2 and PIF4 in Group A was 27, 34 and 36, respectively. The corresponding numbers for Group B were 30, 29, and 29. No effect of training was seen in 3-y-old children. Individual training by a nurse was associated with a statistically significant increase in PIF2 (10 l/min; p = 0.014). Moreover, 2 weeks of home training was associated with an additional increase in PIF of 8 l/min compared with Group B (p < 0.015). After individual instruction and home training, mean PIF in children aged 4 and 5 was 56 (42-72) and 55 (41-66) l/min, respectively.

Conclusion: After individual instruction and training at home, the vast majority of children aged 4 and 5 y can use Turbuhaler correctly. Audiovisual information and individual instruction is not sufficient in the majority of these children. Few 3-y-old children can learn the correct use of Turbuhaler.
