title: [Correlation between E.N.G. changes and the evolution of the hematic constants in patients under prolonged hemodialysis and renal transplantation].
abstract: An evolutive study of the E.N.G. on 25 patients affected of chronic renal failure (c.r.f.) in their previous periods and during the dialysis programme was developed. At the same time a large study on various serum changes was carried on. It is observed that the motor conduction velocity (M.C.V.) shows a decreasing evolution during dialysis, which mathematical patters is a branch of an equilateral hyperbola, of equation: (see article) The Na and K evolutive curves are also significatively fitted to the same mathematical pattern. It is observed a direct and inverse lineal correlation between M.C.V. values and those ones of the Na and K respectively, with p less than 0,05 and p less than 0,01. It is not observed any correlation of significatively value with the other serum parameters studied (R.A., Cl, Urea, Total proteins, Hematocrit, Ca, P, Creatinine, fluids and acid-base equilibrium). After a renal transplantation the M.C.V. presents a growing trayectory of the same mathematical pattern described before, reaching normal values about a year post-transplantion. The levels of Sodium serum follow a parallel trayectory than that one of the M.C.V. The recovery of the remainders serum parameters after renal transplantion occour during the first week, except for the hematocrit. It only remains a parallelism between the evolutive changes of M.C.V./Natremia during dialysis stage and after renal transplantion. These results seem to show a close dependence between variation of M.C.V. and Natremia. The hipoxia role over the sodium pump and the consequent variations of Natremia are discussed.
