[Neonatal characteristics in the physiopathology of shock]

In this work we tried to analyse the different factors which cooperate to produce and maintain a shock condition; we considered in particular pathophysiology and haemodynamic features of the different types of shock and the pathophysiology of MOSF (multiple systems organ failure). Furthermore, we remembered peculiarities and effects of the "reperfusion syndrome" which can occur after cardiopulmonary resuscitation of the patient due to superoxides. Finally we outlined the substantial and significant differences between newborn and not newborn concerning the haemodynamic responses and the cardiocirculatory management in the newborn during shock treatment.
