Abstract 9421: Additional Wiping of the Skin With 70% Isopropil Alcohol Just Before Routine Povidone-Iodine Antisepsis Reduces Cardiac Implantable Electronic Device Infections
Introduction: Cardiovascular Implantable Electronic Device(CIED) Infections are one of the most serious complication after CIED implantation or replacement. To prevent infection, appropriate skin antisepsis and perioperative antibiotic prophylaxis at CIED implantation/replacement are important. But the most optimal antisepsis for CIED surgery is not well defined. Then we assessed whether additional wiping of the skin with 70% isopropyl alcohol just before routine skin antisepsis with povidone-iodine reduces the incidence of CIED infection.
Methods: Consecutive 473 cases of CIED implantation or generator replacement from Jan.2008 to Dec.2013 at one community hospital were divided into two groups according to preoperative skin antisepsis with 70% isopropyl alcohol wipes lasting for at least 1 minute just before povidone-iodine scrub and paint(IPA group, n=183), or povidone-iodine only(No IPA group, n=290). All cases received perioperative antibiotic prophylaxis 30 minute before and 6 hours after procedure. Incidence of CIED infection requiring complete extraction of the leads and the generator within 1-year after implantation/replacement were compared between two groups by Kaplan-Meier analysis.
Results: There were no significant difference in background CIED infection risk factors identified by past studies (diabetes, renal insufficiency, anticoagulant use, corticosteroid use, tempolary pacing, and generator replacement) between two groups. During the follow up period, 8 cases of confirmed CIED infection requiring complete extraction were identified, 6 pacemaker and 2 implantable cardioverter-defibrillator(ICD) or biventricular ICD. All infected cases belonged to No IPA group (p = 0.0235).
Conclusions: In conclusion, wiping of the skin with 70% isopropyl alcohol just before routine antisepsis with povidone-iodine at CIED implantation/replacement significantly reduces the incidence of infection.
