Text Box: TRAINING OF INHALED MDI TECHNIQUE IMPROVED PEFR IN CHILDREN WITH ASTHMA Mu HM, Liu CF, Huang Y Dalian children’s hospital, Dalian, China Objective: To observe the effects of training of inhaled MDI (Vetolin) technique on improving of wheeling in children with asthma Methods: professional nurse trained 45 children with asthma in 6-14 years old for mastering the skill of inhaled MDI of Vetolin (β2–receptor agonist), monitored their PEFR before inhaled MDI, in 5 minutes or 30 minutes after inhaled MDI, to observe the change of PEFR. Results: After training 45 children were divided into two group .A group, 31 children, already mastered the skill; B group,14 children, did not so. The mean of PEFR before inhaled MDI, in 5 minutes and 30 minutes after inhaled MDI in A and B group respectively was 190.97±67,179.29±100.5; 224.06±69.28, 200±93.89; 242.29±69.51, 215±92.79. The mean of PEFR in 30 minutes after inhaled MDI was markedly higher as compare with that before inhaled MDI in A group (P<0.01). The charge of PEFR’mean was not difference in same time in B group (P>0.05). The ΔPEFR’mean between before inhaled MDI and in 5 minutes after inhaled MDI was distinct in A and B group (P<0.05). Conclusions: Trained of inhaled MDI of Vetolin (β2–receptor agonist) technique, children with asthma could master the skill better, helped to the improving of wheeling .The training work should be extended in nurse. 1083
