Shock patient treatment, to correct the cause of shock, to avoid further deterioration of shock, but also to fight shock, correct the state of shock, to reduce the damage of shock to human organs. When correcting the state of shock, it is often necessary to lance rapid infusion of fluids, replenish blood volume, that is, expansion, also called fluid resuscitation, expansion of the fluid used can be divided into crystalloid and colloid, crystalloid mainly has 0.9% sodium chloride solution (saline), compound sodium chloride solution (Ringer’s solution), hypertonic saline, balanced salt solution, it is recommended to give priority to balanced salt solution; colloid solution has low molecular dextrose, hydroxyethyl The colloid fluids are low molecular dextrose, hydroxyethyl starch, albumin, and fresh frozen plasma. Shock expansion should be avoided when using glucose solution, one is not expansion, but also easy to cause cell edema and blood glucose elevation, the other is cardiac causes of shock is also known as cardiogenic shock, expansion is to be cautious.
