Abstract

Purpose: Extravasation incidence is exceptionally low; however, ulceration or necrosis occurs in severe cases, possibly requiring surgical treatment. Early extravasation signs and symptoms are not always evident on treatment day, and inflammation, which leads to ulceration or necrosis, may appear several days later. Therefore, to minimize damage, identification of high-risk groups is required. This study aims to investigate the relationship between subcutaneous edema which is an early extravasation sign, and skin surface temperature using a thermosensitive liquid crystal film. Methods: Patients receiving chemotherapy through a peripheral intravenous catheter were recruited. Subcutaneous tissue around the catheterization site was observed for the presence of subcutaneous edema by ultrasonography. During chemotherapy initiation, a thermosensitive liquid crystal film was placed on the catheterization site. Color changes of the film were observed, and each case was classified according to low-temperature distribution patterns. To investigate the factors associated with temperature distribution pattern, logistic regression analysis was performed using clinically selected independent variables. Results: Data from 63 patients were analyzed. No obvious extravasation was observed. Film analysis revealed 34 cases of broadening low-temperature area from the vein and 23 cases of non-broadening low-temperature area from the vein. Subcutaneous edema was observed in 18 patients: 17 with broadening low-temperature area from the vein and 1 with non-broadening low-temperature area from the vein. Subcutaneous edema was positively correlated with broadening low-temperature area from the vein. Conclusion: Catheter site skin temperature distribution pattern during chemotherapy was associated with subcutaneous edema which is the early extravasation sign immediately after chemotherapy.
