Effect of vest cardiopulmonary resuscitation rate on cardiac output and coronary blood flow.

We studied the effect of CPR rate on the hemodynamic indices of surgically instrumented canine experimental models. Using pneumatic vest CPR, we applied simultaneous rib cage and abdominal compressions at rates of 1 to 12 Hz. CPR with 2-Hz frequency yielded the highest aortic and coronary flows (252 +/- 14 and 6.8 +/- 1.1 ml/min vs. 178 + 12 and 0.96 +/- 0.08 ml/min at 1 Hz, respectively; p less than .005). The validity of the present American Heart Association recommendation for 1-Hz CPR rate would benefit from further studies.

Bleeding small-bowel varices.

A case of bleeding jejunal varices in a 27-year-old man is reported. Portal hypertension resulted from portal vein thrombosis and the varices were not associated with portasystemic shunting. Because mesenteric varices are rare, they are seldom the cause of gastrointestinal hemorrhage. However, they should be suspected in patients with an obscure source of bleeding and portal hypertension. The pathogenesis, roentgenographic criteria and surgical management are discussed.
