MARQUINA PARRA, Dolores et al. Influence of intense shaking of the effluent in automatic peritoneal dialysis in calculating the dialysis dosage. Rev Soc Esp Enferm Nefrol [online]. 2006, vol.9, n.4, pp.49-53. ISSN 1139-1375.

Introduction. The methodology, taking of blood and peritoneal effluent (PE) samples and formulae used to calculate the dosage of peritoneal dialysis should be standard. DOQI guidelines recommend mixing all the PE and shaking it well. Objective. To study whether there were differences in determining Cr and urea before and after shaking the PE and whether they affected the calculation of KT/Vs and ClCr/1.73 m². Material and methods. In 13 stable patients on APD25 urea and Cr tests were carried out before and after shaking the PE container. The KT/Vs and ClCr/1.73 m² of the P^D were calculated with the blood sample obtained 1-3 hours after finishing treatment. Conclusions. Shaking the PE prior to taking samples did not modify the result in urea and Cr and therefore of the KT/Vs and ClCr/1.73 m² in our patients. The different results compared to other studies may be explained by other factors such as the time elapsed since the end of the APD and the taking of the sample or the total volume.
