The best method to assess the adequacy of replacement of fluid in a case of shock is:: (A) Decrease in thirst, (B) Increased PaO, (C) Increase in urine output, (D) Blood pressure
Answer is C. The primary goal in fluid resuscitation for all forms of shock is the same: restoration of adequate end organ perfusion. Urine output is a quantitative and relatively reliable indicator of organ perfusion. It is a reflection of kidney perfusion and function and an indicator of renal, cardiovascular, and fluid volume status. Must know: Signs of a successful initial resuscitation: Improved blood pressure Improving level of consciousness Improving peripheral perfusion Decreasing tachycardia Decreasing lactate Normalizing pH Ref: Holcroft J.W., Anderson J.T., Sena M.J.
