Abstract

Purpose : The results of pulmonary function test (PFT) in children are variable according to the patient's cooperation and comprehensiveness. This study has intended to figure out the effectiveness of pre-education and training with balloons on PFT in children. Methods : One hundred six children mean aged $9.35{\pm}2.92\;years$ were tested. All participants performed PFT twice in 30 minutes intervals. First PFT were performed after usual instruction and second PFT were performed according to randomly classified grouping; Group 1 : repeat PFT after training with balloons, Group 2 : repeat PFT after training and education, both, Group 3 : repeat PFT after education about objects and necessities of pulmonary function test, Group 4 : repeat PFT without any education and training. Results : There were no difference statistically on the results of percent of predicted $FEV_1$, $FEV_1/FVC$, $FEF_{25-75%}$ and PEFR in Group 1, 2 and 4 patients. In some cases, the average is decreased with repeated PFT. At the case of repeated PFT after education, the average of percent of predicted $FEV_1$, $FEV_1/FVC$, $FEF_{25-75%}$ and PEFR is increased. There was statistically significant difference on the value of $FEV_1$, $FEF_{25-75%}$ and PEFR between first and second PFT in Group 3. Conclusion : Training with balloons before PFT causes fatigueness and lowers concentration. Understanding of PFT makes results better than training. Therefore, enough explanation and education about PFT before examination is most effective for appropriate PFT in children.

목 적 : 폐기능 검사는 폐질환의 평가에 매우 중요하여 반복해서 검사를 시행하여 질병의 경과와 치료에 대한 반응을 객관적으로 평가할 수 있다. 소아에서는 협조와 이해 정도에 따라 수치의 변동이 크므로 풍선을 이용한 연습과 검사에 대한 이해가 결과에 어떤 영향을 미치는지 분석하고자 한다. 방 법 : 2006년 6월부터 10월까지 천식으로 순천향대학교병원 소아과 알레르기호흡기센터를 방문하여 폐기능 검사를 실시한 106명을 대상으로 하였다. 첫 검사 시행 후 풍선불기 연습을 시킨 후 다시 검사한 군, 연습과 검사의 필요성에 대한 교육을 시킨 후 다시 검사한 군, 교육만 시킨 후 다시 검사한 군, 그대로 다시 검사를 시행한 군 등 4군으로 나누어 검사 수치를 비교하였다. 결 과 : 연습 전후의 검사 결과는 통계학적으로 유의한 차이는 없었다. 연습과 교육을 시행하여 전후의 검사 결과를 비교했을 시에도 유의한 차이는 없었다. 교육만 시행하였을 경우 $FEV_1$, $FEV_1/FVC$, $FEF_{25-75%}$, PEFR의 평균치가 전반적으로 상승하였으며 $FEV_1$, $FEF_{25-75%}$, PEFR은 통계학적으로 의미가 있는 상승을 보였다. 교육이나 연습을 시행하지 않고 2회 검사 시행시 유의한 차이는 없었다. 결 론 : 폐기능 검사 시행시 풍선 등을 이용하여 연습을 시키거나 여러차례 반복하여 검사를 시행하게 될 경우 오히려 검사 결과에 나쁜 영향을 줄 수 있고 검사의 필요성에 대해 잘 이해를 시킨 후 검사를 하는 것이 정확한 결과에 더 큰 영향을 미치는 것으로 보여지며 이를 바탕으로 향후 폐기능 검사 시행시 체계적으로 검사에 대한 설명을 하여 환아가 충분한 이해를 하도록 하는 것이 필요하다고 할 수 있겠다.
