Abstract:
Objective To explore the better lock solutions of temporary catheter for patients with cont inuous renal replacement therapy (CRRT) in intensive care unit. Methods A total of 235 patients with insertion of temporary central venous catheters were divided into two groups randomly. 500 U/ml heparin saline was used in the observational group (123 cases) and 1 000 U/ml heparin saline was used in the control group (112 cases). Two groups adopted positive pressure seal tube method, and the situation of catheters and bleeding were observed. Results There were no statistical significance of two groups in the situation of catheters and bleeding (P>0.05). Logistic regression:8 observational factors (machine type, dilution method, catheter placement, blood flow velocity, the use of anticoagulants, whether to use immunity inhibitors, whether for high blood pressure, diabetes) in the Logistic regression, no factors was found to have association with the situation of catheters (P>0.05 ), 2 factors were found to have association with bleeding (P<0.05 ), one hazard effect:the maximum flow of blood, one positive effect:the position of catheter. Multiple linear regression: 6 observational factors [hemoglobin, acute physiology and chronic health evaluation (APACHE)Ⅱ, C-reactive protein, systolic pressure, diastolic pressure, activated partial thromboplastin time (APTT)] in the multiple linear regression, two factors were found to have association with the situation of catheters (P>0.05 ), all of them had positive effect: APACHEⅡ,APTT; two factors were found to have association with bleeding (P < 0.05), all of them had hazard effect: APACHEⅡ,APTT. Conclusions Compared with 1 000 U/ml, 500 U/ml heparin lock solutions doesn′t increase the thrombosis of temporary catheters, and also decrease the rate of bleeding,so 500 U/ml heparin lock solutions can use in CRRT patients who use anticoagulant.
