Abstract
In experiment 1, we evaluated our method of catheter care at subclavian vein insertion sites for the control of catheter-related infections in seriously ill neurosurgical patients who needed prolonged catheter placement, compared with an older method. In our method, the insertion site was prepared with 10% povidone-iodine solution, followed by application of 10% povidone-iodine ointment, and covered with sterile gauze and a transparent polyurethane dressing. The older method was based on 1996 guidelines for the prevention of intravascular device-related infections. Catheter colonization and mortality were both found to be significantly reduced with our method (p = 0.0214, p = 0.0379, respectively). In experiment 2, we evaluated whether a regimen of catheter care with 10% povidone-iodine ointment was more effective than that without povidone-iodine ointment for the prevention of infections. This suggested effectiveness of 10% povidone-iodine ointment for reduction of infection. Our method of catheter care was useful even in seriously ill neurosurgical patients.
