title: [Polyneuropathy in the critical ill patient: a common diagnosis in intensive care medicine?].
abstract: OBJECTIVE
  The diffuse axonal polyneuropathy, more commonly known as Critical Illness Polyneuropathy (CIP), has been discussed by authors by decades; however, it has only been deeply studied over the last thirty years, becoming more important as an important cause of long term dependence on mechanical ventilation by seriously ill patients in intensive care medicine.
  
  
  BACKGROUND
  A significant reason for such interest is due to the importance of the CIP as complication of the septic shock and in patients with multiple organ failure, as much as responsible for the prolonging hospitalization in the Intensive Care Unit, as for the gradual reduction of the chance of survival. It has been suggested that the polyneuropathy is related with cytokines and other mediators which would increase the permeability of the vases, resulting in endoneural edema and causing the axonal injury. It is difficult to do the initial diagnostic, which, in general, are only possibly recognized when the sepsis complications or the multiple organs failure have been satisfactorily controlled. The diagnosis is made through the eletroneuromiography exam, and although there is still no effective drug treatment other than the control of the basic illness, it is consensus among multidisciplinary team that the development of the CIP does not have to be understood as a way to reduce the intensity of treatment.
  
  
  CONCLUSIONS
  Spit of your prevalence, it is still unknown the mainly factors which are physiopathology associated as soon as your correct therapy.
