Clinical contrast study of antibacterial action by urinary catheters coated with nanometersilver
【Abstract】 AIM: To study the antibacterial action of urinary catheters coated with nanometersilver. METHODS: Catheterized patients in neurosurgery department were randomly divided into 2 groups：ordinary urinary catheter group and urinary catheter coated with nanometersilver group. After the patients with catheterization time less than 7 d were rejected， all 30 patients were studied including 17 with urinary catheter coated with nanometersilver and 13 with ordinary urinary catheter. Urine routine and urine culture were done before and 7, 14, 21, 28 d after urethral catheterization. The end of urinary catheters was cultured after a urinary catheter was pulled out. RESULTS: The positive number of urinary leukocytes before and 7, 14, 21, 28 d after urethral catheterization was 1, 5, 6, 8, 9, respectively for ordinary urinary catheter group,but for urinary catheter coated with nanometersilver group it was 0, 1, 2, 4, 5, respectively (P
