Outline of Final Research Achievements

In order to establish effective rehabilitation interventions as a strategy for early weaning of pediatric patients on ventilators, a novel evaluation method is required for pediatric patients who cannot be encouraged to follow instructions, since there is no established method for evaluation of respiratory capacity. The aim of this study was to quantitatively evaluate respiratory status in children using ultrasonography, which is commonly available at each medical institution, and to search for effective respiratory rehabilitation procedures. Diaphragmatic ultrasonography was able to capture changes in breathing patterns following respiratory physiotherapy intervention.

Academic Significance and Societal Importance of the Research Achievements

小児における呼吸状態の評価は臨床医の経験に依存する部分が大きくまた数値化することは難しい。超音波検査により評価は経験によらず定量評価ができるため、今後の介入法の検討に活かせる可能性が示された。また超音波検査装置は通常診療に利用しているものを応用することができるため、高価な機材を購入することなく広く汎用できる。本邦の小児の人工呼吸器管理の発展につながり、予後改善につながることが期待される。
