The main goal of the hemodialysis (HD) patient is to achieve adequate dialysis: an effective, sufficient, well tolerated treatment that improves the patient's survival.
The dialytic dose (DD) is a good marker of adequate dialysis.
There are different
quantitative methods to determine the DD, being the most used the Kt / V.
Another factor that also influences patient survival is having good vascular access (VA).
Currently, carriers of tunneled venous catheters (TVC) are on the rise.
Evaluate the dialysis dose depending on the vascular access.
SPSS 15.0 Windows.
Descriptive analysis: half, standard deviation, median,
frecuency and percentage.
Hypothesis contrast: studentT, statistical analysisent, chi cuadrado, ANOVA.
Statistical significance p <0.05
There is no difference in DD depending on the vascular access employed.
In spite of the high percentage of patients dialysed through CP, almost 80% of the sample achieved an adequate Kt / V, reaching the adequate quality standards.
