Nursing care of the ambulatory patient with a mechanical assist device.
Since 1986, 10 men and one woman were ambulatory while supported with mechanical assist devices as a bridge to heart transplantation. Four patients received a subclavian intraaortic balloon pump, two were supported with a Novacor left ventricular assist system, three patients received Pierce-Donachy ventricular assist devices, and one patient received a Jarvik 7 total artificial heart. One patient with an intraaortic balloon pump later received a left ventricular assist system because of hemodynamic deterioration despite the intraaortic balloon pump. Before device insertion all 11 patients were in cardiogenic shock despite inotropic and vasodilator support. The time of support ranged from 8 to 440 days (median, 24 days). In-house coverage by the circulatory support team was necessary only during the first 24 to 72 hours of support. When the patient's condition was stabilized, nursing staff monitored the devices with "on-call" availability of the circulatory support team. After implant of the device, all patients were able to perform activities of daily living. Once patients were able to walk in their hospital rooms, ambulation began in the hallways; frequency and distance were gradually increased. Four of the patients walked outside the hospital while tethered to the drive console. Daily physical therapy contributed to increased exercise tolerance. Protective isolation was used before and after transplantation to minimize the risk of infection. Sterile dressing changes (gown, gloves, mask) were applied to drive lines, cannula sites, and incisions. All invasive lines and catheters were removed as soon as the patient's clinical condition warranted, and noninvasive monitoring was used to decrease the chance of infection.(ABSTRACT TRUNCATED AT 250 WORDS)
