[EX Q]: Abstract: To assess whether continuous arteriovenous ultrafiltration (CAVU) might constitute a useful alternative to hemodialysis in the management of patients with advanced liver failure, we carried out CAVU in 3 patients with decompensated Laennec's cirrhosis. CAVU was utilized in two patients with acute renal failure and pulmonary edema to stabilize renal function and facilitate administration of large amounts of fluid. In the third case, CAVU was successfully utilized to mobilize fluid in a patient refractory to conventional diuretic regimens. We conclude that CAVU may constitute an appropriate alternative to traditional hemodialysis in patients with advanced liver disease and renal functional impairment.

[EX Q]: Abstract: To study patient preferences on physician attire and etiquette, we interviewed 200 patients on the general medical services of teaching hospitals in Boston and San Francisco. Of these 200 patients, 65% believed physicians should wear a white coat, 27% believed physicians should not wear tennis shoes, 52% believed physicians should not wear blue jeans, 37% believed male physicians should wear neckties, and 34% believed female physicians should wear dresses or skirts. Forty percent of patients wanted physicians to address them by first name, but only 10% of patients wanted to address their physicians by first name. A concurrent mailed survey of 74 medical house staff members at the two hospitals revealed wide variability in physicians' attire and in how patients were addressed at each institution. Thus, many house officers had habits that were less formal than a substantial portion of their patients preferred.

[EX Q]: Abstract: Over the last two decades, emergency medical services in the United States have been greatly improved. Organization of prehospital providers of health care has improved the outcome of many patients, particularly the trauma patient and the acute cardiac patient. In Seattle as many as 40% of outside-the-hospital cardiac arrest victims with ventricular fibrillation have been saved when there is rapid delivery of basic life support by first responders followed by advanced life support by paramedics. Although these systems are growing and improving health care, many lack adequate medical control or physician involvement. Emergency medical service systems must have physicians involved in their management to meet their full capabilities. It has become apparent that four factors are critical in determining the ability to resuscitate an individual once a cardiac arrest has occurred: time to starting any of the rescue procedures, use of electrical defibrillation when indicated, use of epinephrine, and adequacy of the technique of basic life support, particularly the ventilation component. To provide defibrillation at the earliest possible time, defibrillation by first responders such as emergency medical technicians appears to be of benefit. With the advent of automatic and semiautomatic defibrillators, first responders and family members may also be able to defibrillate victims. The use of defibrillation by people with less training than paramedics, however, must be approached with caution to ensure that there is adequate medical control and that the individuals who use these devices are properly trained.
