Metabolic acidosis immediately after surgical operation is followed by metabolic alkalosis. Hormonal change by surgical stress and anaerobic glucolysis due to tissue ischemia cause initial lactic acidosis. Later alkalosis may be caused by secondary aldosteronism and bicarbonate production from lactate and citrate supplied by massive infusion and transfusion. Postoperative complications, such as respiratory insufficiency, renal failure and hypovolemic or septic shock, cause acidosis. In the gastrointestinal surgery, acidosis can be caused by starvation and loss of bicarbonate contained in bile, pancreatic juice or intestinal fluid, and alkalosis can be caused by loss of HCl in gastric juice. Severe acidosis can be caused by extracorporeal circulation, hypothermia, low output syndrome or declamping shock in cardioaortic surgery.

A 23-year-old male was admitted to hospital with severe dehydration and hypokalemic myopathy due to secondary aldosteronism. On admission serum sodium and chloride were markedly elevated to 198 mEq/l and 169 mEq/l, respectively, and serum potassium was down to 2.3 mEq/l. Serum electrolytes were normalized by transfusion therapy, but subsequently rhabdomyolysis grew worse due to metabolic abnormalities such as dehydration, hypothermia, oppressive ischemia and metabolic acidosis, at the same time transient polyuria and the elevation of serum myoglobin and enzymes originating in muscle tissue were observed. Serum CPK went up to 26,532 IU/l on the sixth day and other enzymes reached a peak following CPK. Dexamethasone was administered when the increase in enzyme levels caused the patient to fall into a stupor. He rapidly regained consciousness from the 15th day after admission, and he was able to stand up on the 29th day. Serum enzymes originating in muscle tissue decreased gradually to the normal range by the 30th day and no renal failure occurred.

The aim of this work is to present some practical, postmortem biochemistry applications to illustrate the usefulness of this discipline and reassert the importance of carrying out biochemical investigations as an integral part of the autopsy process. Five case reports are presented pertaining to diabetic ketoacidosis in an adult who was not known to suffer from diabetes and in presence of multiple psychotropic substances; fatal flecainide intoxication in a poor metabolizer also presenting an impaired renal function; diabetic ketoacidosis showing severe postmortem changes; primary aldosteronism presented with intracranial hemorrhage and hypothermia showing severe postmortem changes. The cases herein presented can be considered representative examples of the importance of postmortem biochemistry investigations, which may provide significant information useful in determining the cause of death in routine forensic casework or contribute to understanding the pathophysiological mechanisms involved in the death process.
