TOBO MEDINA, Natalia. Evaluation of a nursing intervention to prevent clotting of the extracorporeal circuit in hemodialysis. Enferm. glob. [online]. 2015, vol.14, n.40, pp.276-285. ISSN 1695-6141.

Background: The coagulation of the out-of-body circuit is one of the complications in hemodialysis. In order to reduce its appearance it is required, besides the anticoagulation, the design and standardization of the nursing intervention. Objective: Evaluate the effectiveness of the nursing care program to prevent the coagulation of extracorporeal circulation during the hemodialysis. Methods: Twenty patients selected at random were studied through an almost experimental study in non-recurring groups. 120 observations were made. Were used: percentages, average frequencies, the standard deviation (DE), the t-Student and the Wilcoxon signed- ranks test. Statistical significance was accepted for p<0.05. Results: The results support the hypothesis about the effectiveness. Significant differences were observed in the decrease coagulation of extracorporeal circulation, among the sessions with and without the application of the care program. The arterial chamber showed the highest number of events with 58% without intervention, versus 6.6% with intervention. Secondly, the vein chamber with 35% vs. 3.3%. Conclusion: The effectiveness of the program proposed in the prevention and decrease of the coagulation extracorporeal circulation, was proved; suggesting the importance for this kind of interventions to be standardized in the kidney units in order to provide a better quality therapy and a better life quality of the patient.
