목 적 : 고막체온계는 신체내의 점막과 접촉 없이 고막을 통해 심부체온을 신속히 간편한 방법으로 측정할 수있어 영아와 소아들에서 많이 사용된다. 본 연구에서는한쪽에만 중이염, 귀지가 있는 경우 양쪽 고막체온이 어떻게 달라지는지 연구하였다. 방 법: 2008년 6월부터 9월까지, 2010년 1월부터 5월까지 본원 소아청소년과 외래에 내원한 소아 중 비디오 이경을 통해 중이염과 귀지가 없는 정상군 50명, 한쪽에만 고막이 안보이게 귀지가 가득 있는 군 50명, 한쪽에만 중이염을 가진 군 186명의 3개 군을 대상으로하였다. 고막체온은 Braun Thermoscan을 이용해 양쪽귀에서 2초간 측정하였고, 15분 뒤 다시 측정하였다. 중이염을 가진 군은 비디오 이경으로 확인하여 염증정도에따라 분류하여 비교하였다. 통계처리는 SPSSWIN 12.0을 사용하였고 paired T-test와 one way anova를 이용하여 분석하였다. 결 과 : 정상 군과 한쪽에만 귀지가 있는 군에서는 양쪽 고막체온의 통계적인 차이는 없었다. 한쪽에만 중이염이 있는 군에서는 중이염이 있는 쪽의 고막이 평균0.13±0.20℃ 높았고 통계적인 차이가 있었다(36.99±0.54℃ vs 36.86±0.52℃; P <0.001). 중이염의 단계에따른 양쪽 고막의 체온차이는 통계적으로 유의하지 않았다. 결 론 : 고막체온계는 스트레스 없이 쉽고 빠르게 체온을 측정할 수 있다. 적절한 방법으로 측정한다면 양측 고막체온에는 큰 차이가 없을 것으로 생각되나, 중이염이있을 때엔 양쪽 고막체온에 차이가 있을 수 있음을 주의해야겠다.
Abstract
Purpose : To examine the effect of unilateral otitis media and unilateral cerumen occlusion of the ear canal on thermometers. Methods : One hundred eighty six children with unilateral otitis media, fifty children with unilateral cerumen occlusion, and fifty children with neither otitis media nor cerumen were enrolled. Temperature was measured in both ear canals using thermometers. After 15 minutes, second temperature was measured again in both ears. Unilateral otitis media was graded by video otoscope for 7 grades. Differences in temperatures between affected ears and unaffected ears were analyzed. Results : No temperature difference between the normal and cerumen groups was observed. The mean temperature of the otitis media ear canal was 0.13±0.20℃ higher than that of the intact ear canal (36.99±0.54℃ vs 36.86±0.52℃; P <0.001). There was no statistically significant temperature difference between grades. Conclusion : Unilateral otits media can affect estimation of body temperature measured by thermometers.
