What is the best measure of the adequacy of cellular perfusion and can help to predict the outcome of resuscitation? A.End-tidal carbon dioxide B.Hematocrit level C.Base deficit D.Oxygen saturation {Ans: C.Base deficit Rationale A: Carbon dioxide measurement is the end-product of ventilation and a reflection of metabolism and pulmonary function. In order to measure cellular perfusion, base deficit, in conjunction with serum lactate, is the best measure. B: Hematocrit is the percentage of red cells in the blood. It does not directly reflect the adequacy of cellular perfusion, nor does it predict resuscitation outcomes. The best method of determining cellular perfusion is base deficit, in conjunction with serum lactate. C: Base deficit serves as an endpoint measurement of the adequacy of cellular perfusion and, when used in conjunction with serum lactate, helps predict the success of the resuscitation.D: Oxygen saturation is valuable for measuring the trend in oxygenation within the bloodstream but does not reflect cellular perfusion.}A adult patient with a knife injury to the neck has an intact airway and is hemodynamically stable.
