Abstract
Objective To compare the effect of the 2% chlorhexidinegluconate disinfectant and 0.5% iodophor disinfectant on the maintenance of central venous catheter (CVC) in patients with immunodeficiency. Methods The patients were randomly divided into two groups. 2% chlorhexidinegluconate disinfectant was used in the experimental group, and 0.5% iodophor disinfectant was used in the control group. The CVC was sterilized once a week and continuously maintained for 3 weeks. According to the condition of catheter, the dressing was changed in time in case of any problem,and the reason and time for the catheter nursing care were recorded. The duration of changing the catheter dressing in different disinfectant, incidence rate of dressings looseness and incidence of catheter-related infections in two groups were analyzed. Results The duration of skin drying and duration of caring in the experimental group were (0.62±0.10)min, (11.67±0.33) min, significantly shorter than the control group [(1.97±0.18) min, (14.48±0.33) min](t values were 63.044, 57.296, P 0.05). Conclusions Both 2% chlorhexidinegluconate and 0.5% iodophor disinfectant have similar disinfection effect on CVC caring, but 2% chlorhexidinegluconate disinfection is more efficient and worthy of application in clinical settings. Key words: Chlorhexidinegluconate; Iodophor; Hematopoietic stem cell transplantation; Central venous catheter
