Abstract:
ObjectiveTo explore the factors related to infections of intravenous catheter as well as preventive measures.MethodsIn 598 cases of patients with central venous catheterization,indwelling time,location,bacteriology were monitored among 130 patients with suspected venous catheter infection.ResultsIndwelling catheter lasts for 3 days at least,70 days at most.For 77 out of toual cases,microbiology culture of catheter tip and blood culture were positive,accounting for 12.88％.Detected pathogens were 151 in total.Gram-negative bacteria were 48(31.79％),gram-positive bacteria were 78(50.65％),fungal were 25 (16.56％).Among these,the most common pathogens were Staphylococcus epidermidis,Staphylococcus aureus,Candida and Acinetobacter,most of the bacteria had a high degree of drug resistance.The choice of position:infection rate of subclavian vein and basilic vein was lower than that of the superclavian vein and internal jugular vein,infection rate of catheterization time ≤ 13d was lower than that of ≥ 14d.ConclusionsThe choice of subclavian vein and basilic vein,standardization of puncture technical,strict catheter care,shortening of catheterization time and improvement of the general condition of patients can reduce catheter-reiated infections.The rational use of antibiotics is a critical measure to reduce vascular catheter infections of patients.
