국소적 냉 요법이 정상 성인의 조직과 말초의 산소포화도, 말초 혈류, 피부 온도, 체온에 미치는 효과 = Effects of local cold application on tissue & peripheral oxygen saturation, peripheral blood flow, skin temperature, and body temperature of healthy adult

다국어 초록 (Multilingual Abstract)

Purpose: This study aimed to establish a basis for application time and cold therapy interval by checking the physiological changes after applying a cold-gel and ice pack, commonly applied to cold therapy, and after passive rewarming. Method: A total of 22 healthy adults used cold-gel packs and ice packs in a Randomized control group repeated measurement study, and passive rewarming was performed for 40 minutes after 30 minutes of cold therapy. After applying to the right axilla, StO₂, SpO₂, peripheral blood flow, skin and body temperature were measured 15 times every 5 minutes. Result: In the cold-gel pack group, StO₂ decreased from 69.43% to 61.06% after 30 minutes application, and in the ice pack group, StO₂ decreased from 67.66% to 64.80% (p <001). In the cold-gel pack group, skin temperature decreased from 33.57°C to 29.15°C after 30 minutes application, and in the ice pack group, skin temperature decreased from 32.64°C to 28.90°C (p <.001). Only skin temperature recovered completely after 40 minutes of rewarming. There were insignificant differences between the cold-gel pack and ice pack. Conclusion: When applying cold therapy to the axillary, at least 40 minutes for passive rewarming is necessary after 30 minutes of application.

목적: 본 연구는 국소적 냉 요법 중 가장 일반적으로 적용하는 냉 젤 팩과 얼음 팩을 적용 한 후와 수동적 재가온 후의 생리적 변화를 확인하여 냉 요법의 적용시간과 간격에 대한 근거를 마련하고자 합니다.
방법: 무작위 비교군 반복측정 실험연구로 건강한 성인 22명을 냉 젤 팩과 얼음 팩 그룹에 무작위 배정하여 30분 동안 냉요법을 적용한 후 40분 동안 수동 재가온을 실시했습니다. 오른쪽 액와에 냉요법이 적용되는 동안 5분 간격으로 총 15회, 조직과 말초의 산소포화도, 말초혈류, 피부온도, 체온을 측정하였습니다. 결과: 냉 젤 팩 군에서 StO₂는 냉 요법 전 69.43%였고, 냉 젤 팩 적용 30분 후 61.06% 였으며 얼음 팩 군에서 StO₂는 냉 요법 전 67.66%였고, 얼음 팩 적용 30분 후 64.80%로 크게 줄었습니다.(p <.001) 냉 젤 팩 군에서 피부온도는 냉 요법 전 33.57℃였고, 냉 젤 팩 적용 30분 후 29.15℃ 였으며 얼음 팩 군에서 피부온도는 냉 요법 전 32.64℃였고, 얼음 팩 적용 30분 후 28.90℃로 크게 줄었습니다.(p <.001) 40분 재가온 후에는 피부 온도만이 완전히 회복되었습다. 냉 젤 팩과 얼음 팩 그룹 간에는 큰 차이가 없었습니다. 결론: 액와에 국소적 냉 요법을 적용할 때는 30분 적용 후 적어도 40분 이상의 수동적 재가온을 위한 시간을 갖도록 해야 할 것입니다.
