Cardiovascular catheterization using a new antiseptic agent olanexidine gluconate

Abstract

Olanexidine gluconate 1.5% (Olanedine®) is a colorless and transparent antiseptic agent introduced in 2015. In this study, we examined its usefulness and safety for cardiovascular catheterization and compared them to 10% povidone-iodine (PI). The study included 1,001 and 1,000 consecutively enrolled patients using Olanedine® and PI, respectively [649 (PI, 687) males; mean age: 72.1 ± 9.6 (70.9 ± 9.6) years] who underwent cardiovascular catheterization [diagnostic cardiac catheterization: 624 (509) cases, percutaneous coronary intervention: 288 (390) cases, and endovascular treatment: 89 (101) cases]. Clinically, there were no significant differences in the backgrounds between the two groups. The amount of Olanedine® used per case was approximately 20 mL. Blood tests were performed before and after catheterization. The presence or absence of discoloration on clothes containing cotton by Olanedine® was also examined. One mild rash that disappeared within one day occurred in each of the two groups. Some blood tests before and after cardiac catheterization indicated significant differences, but they did not seem to be clinically relevant. The use of Olanedine® in hemodialysis patients (117 cases) was uneventful. Its use in 37 patients with contraindications for ethanol disinfection was also uneventful. Although PI is extremely difficult to remove from white coats containing cotton, Olanedine® did not cause any discoloration on clothes. This is the first report of cardiovascular catheterization using Olanedine®. The efficacy and safety of Olanedine® and PI seem to be equivalent. Olanedine® could be a new useful option as a disinfectant of cardiovascular catheterization.
