Comparative StudyEffects of dopamine, ethanol, and mannitol on cardiopulmonary function in patients with adult respiratory distress syndrome.
Dopamine, ethanol, and mannitol were investigated to determine if they could increase pulmonary blood flow and oxygen delivery without significantly increasing intrapulmonary shunt. These drugs were studied in adult patients with respiratory distress following trauma, operation, or sepsis. Intravascular pressure, cardiac output, oxygen consumption and delivery, and limb blood flow and peripheral oxygen delivery were measured in all patients. ⋯ Mannitol increased oxygen delivery and consumption in both the total body and limb. Thus in patients with adult respiratory distress syndrome (ARDS), increases in pulmonary blood flow can be achieved with several distinct pharmacologic agents without significant increases in intrapulmonary shunt. These increases in flow are generally accompanied by increases in oxygen delivery without increased pulmonary vascular resistance.

Case ReportsRight ventricular bullet embolectomy without cardiopulmonary bypass.
Victims of gunshot wounds may be noted to have bullets overlying the cardiac silhouette on roentgenogram. Direct cardiac penetration, bullet embolus to the heart, and missile proximity to the heart are all possibilities which must be differentiated. ⋯ At the time of exploration, an intracardiac bullet embolus was fortuitously palpated and trapped within the apex of the right ventricle. Right ventriculotomy and embolectomy without cardiopulmonary bypass were performed to prevent retrograde or distal migration.
