First line of therapy in shock in the patient of trauma:-

First line of therapy in shock in the patient of trauma is crystalloids. Resuscitation following blood loss in trauma patients begins with administration of 1 liter of isotonic crystalloid immediately to restore BP and peripheral circulationQ. Lactated ringer (RL) solution is generally preferred over 0.9% NaCl (normal saline) as it is balanced salt solution and designed to mimic extracellular fluidQ. Resuscitation with colloids is no more effective than crystalloids but is more expensiveQ.
