Isolated dissecting hematoma (aneurysm) of a coronary artery is a rare occurrence that often results in myocardial infarction and sudden death. A case of dissecting hematoma involving the left main, left anterior descending, and left circumflex coronary arteries is described in a patient who had received vigorous closed-chest cardiac resuscitation. This is believed to be the first reported case of coronary artery dissection caused by epicardial trauma from closed-chest cardiac resuscitation. This case demonstrates that dissecting hematoma of the coronary artery can be a complication of cardiac resuscitation.

In order to assess the frequency and severity of lactic acidosis and 3-hydroxybutyric acidosis in ethanol abusers, 29 patients who presented to an emergency room with acute intoxication were tested. Most were also chronic ethanol abusers but were not otherwise seriously ill. Their serum ethanol concentrations averaged 226.5 +/- 94.8 mg/dl (range 98 to 426 mg/dl). ⋯ Only two patients had even trivially elevated plasma levels of 3-hydroxybutyrate, 1.0 and 1.2 mmol/liter. Thus, these patients did not have unrecognized "alcoholic ketosis" manifested mainly as 3-hydroxybutyric acidosis. An unexpected and unexplained finding was the presence of hyperchloremia in 10 of the 29 patients, with serum chloride levels of more than 110 mmol/liter.
