Abstract

목적: 조영제 주입 후 발생하는 과민반응 중 환자의 열감은 가장 빈번히 발생하는 부작용중 하나로 실제 환자의 체온 측정을 통해 이 열감이 체온의 상승으로 나타나는지 확인해보고자 한다. 대상 및 방법: 2017년 8월 1일부터 2017년 12월 31일까지 Neck CT (contrast)검사를 시행한 100명의 환자를 대상으로 검사전 액와와 이마(오른쪽 눈썹)의 체온을 기준으로 하여 조영제 주입 후 2분(min)까지 10초 간격으로 측정하였다. 조영제 주입속도 (m/sec)와 양(ml)은 본원의 프로토콜 규정에 따라 2.7m/sec와 90ml로 고정하였다. 측정된 결과는 검사 전 측정값을 T0, 조영제 주입 후부터 30초까지를 T1, 40~70초까지 T2, 80~100초까지를 T3로 구분하여 통계적 분석을 통해 온도변화를 확인하였다. 검사 종료 후 열감의 유무와 정도를 알아보기 위에 리커트 척도(5점)로 기록하였다. 결과: 조영제 주입 시 100명중 88명(88%)이 열감을 느꼈고, 열감의 정도는 리커트 척도 5점기준 3.04점이 나왔다. 이 열감을 실제 측정해본 결과 T0 36.51℃을 기준으로 하였을 때 조영제 주입 후 30초까지 T1에서는 36.53℃로 체온의 변화가 없었고, 40~70초까지 T2에서는 36.72℃로 약 0.22℃ 체온이 상승하였다. 80~100초 구간(T3)은 36.75℃로 T2구간의 체온과 거의 비슷하게 유지되었다. 이 결과는 액와와 이마부위 두 군데 모두 거의 일치하였다. 결론: 조영제 주입으로 인한 열감은 100% 신체의 체온변화로 나타난다는 결과는 유추할 수 없었으나, 대부분의 환자에서 온도 변화를 발견할 수 있었다.Purpose: The heat sensation of the patient during hypersensitivity reactions after contrast media injection is one of the most frequent side effects. The actual patient s body temperature is measured to ascertain whether this heat sensation is caused by a rise in body temperature. Material and methods: A total of 100 patients who underwent Neck CT (contrast) test from August 1, 2017 to December 31, 2017 were measured for pre-test body temperature of axillary and forehead (right eyebrow) at intervals of 10 seconds after the injection of contrast agent. The contrast agent injection rate (m/sec) and volume (ml) were fixed at 2.7 m/sec and 90 ml according to the hospital’s protocol of this application. The measured results were divided into T0, before measurement, T1 for 30 seconds after the injection of contrast agent, T2 for 40 to 70 seconds, and T3 for 80 to 100 seconds and the temperature change was confirmed through statistical analysis. To determine the presence and degree of heat sensitivity after the test, it was recorded by a Likert scale (5 points). Result: 88 patients (88%) felt the feeling of heat, and the degree of sensation of heat was 3.04 points on the 5 points of the Likert scale. The result of the actual measurement of the heat sensation shows that there was no change in body temperature at T1 with 36.53°C for 30 seconds after injection of contrast agent, and at T2 with 36.72°C, an increase of 0.25°C during 40 to 70 seconds. The interval between 80 and 100 seconds (T3) was 36.75℃, which was almost similar to the T2 interval temperature. The results were almost identical in both axillary and forehead areas. Conclusion: It could not be referred from the results that the body temperature must change by heat sensation after injectiong contrast media. However, it was found that body temperature was changed in most patients.
