SIERRA DIAZ, Rubén. Sealing catheters with gelafundin compared to sodium heparin. Rev Soc Esp Enferm Nefrol [online]. 2010, vol.13, n.4, pp.242-245. ISSN 1139-1375.

Most patients who currently commence dialysis are of advanced age and have chronic diseases and vascular complications, requiring the use of central venous catheters to carry out haemodialysis. This situation in our centres has meant that nursing staff have had to adapt their work to the care of these catheters ensuring access to a blood flow that is sufficient for efficacious dialysis. After a change in our unit in the sealing of catheter branches, from a traditional protocol with physiological serum and 5% sodium heparin to another made up of physiological serum and gelafundin, it was suggested that a study be carried out to compare the two protocols, evaluating aspects such as incidence of infections, dysfunctions of the catheter due to obstruction and hospital admissions. The following results were obtained from the comparative study carried out over 1248 dialysis sessions of 16 patients with permanent catheters (624 sessions with each protocol): there were no admissions to hospital deriving from catheter dysfunction; with different protocols infections appeared, mostly local; there were incidents related to blood flow in both types of protocol, with the use of branch inversion being more frequent when primed with sodium heparin and with greater user of protocol with urokinase in the phase of priming with gelafundin.
