초록

조영제의 혈관외유출을 한번이라도 경험한 방사선사들은 혈관외유출의 발생에 대한 두려움으로 검사하는 동안 정신적 고통을 수반하게 된다. 환자의 경우 심한 신체적, 정신적 고통과 의료진 및 의료에 대한 불신을 갖게 되므로 미연에 예방할 수 있는 방안의 마련이 무엇보다 필요하다. 따라서 본 연구에서는 조영제 주입 시 압력인 PSI를 낮추어 혈관외유출을 예방하고자 하며 그 방안으로 자동주입기와 환자의 정맥주사바늘에 연결되는 Y자 형태의 연결관(connecting tube)의 직경에 따른 조영제 주입 시 PSI의 변화를 비교 분석하고자 하였다. Y형태의 연결관 직경이 약 2 mm 정도인 A제품의 경우 전체 평균 연령의 PSI는 98.5, 표준편차 9.72로 나타났다. 연결관 직경 약 3 mm 정도인 B제품의 경우 전체 연령의 평균 PSI는 62.0, 표준편차 8.59로 나타났다. 이것은 직경이 더 넓은 B제품의 경우 A제품과 비교했을 때 평균압력이 37.05% 감소한 결과이다.

Radiologists who experience extravasation of the contrast medium even once suffer mentally during testing due to the fear of its reoccurrence. Establishing a plan for preventing it beforehand is necessary above all because patients experience severe physical and mental pain and become distrusting of medical staff and treatment. Therefore, the present study attempts to prevent extravasation, which is the result of damage from pressure applied to the patient's blood vessels, by lowering PSI, and conducted a comparative analysis of PSI changes during contrast medium injection depending on the diameter of the Y-shape connecting tube which connects the automatic injector and the intravenous injection of the patient. In the case of product A in which the diameter of the Y-shape connecting tube is about 2mm, the average PSI for all ages was 98.5 and standard deviation was 9.72. In the case of product B in which the diameter of the Y-shape connecting tube is about 3mm, the average PSI for all ages was 62.0 and standard deviation was 8.59. Product B with its wider diameter decreased in average pressure by 37.05% when compared to product A, and when product B is used with the p-value at 0.00, pressure decreased even more, achieving statistically significant results.
