Recognition and management of bleeding following cardiac surgery.

The major hemorrhagic disorders are associated with malfunction of three physiologic systems either separately or in combination: (1) abnormalities of platelets, (2) abnormalities of blood vessels, and (3) abnormalities of plasma coagulation factors. Platelets contribute to hemostasis not only by participating physically by occluding rents and tears in small vessel but also by involving the coagulation process through their biochemical activities. It is small wonder that platelet dysfunction is the most common cause of nonsurgical bleeding following CPB; however, the potential for hyperfibrinolysis cannot be overlooked. New laboratory tests and therapeutic approaches have allowed for more accurate diagnosis and more appropriate therapy in a variety of bleeding events following CPB.

Reoperation: cardiac surgery.

The subject of cardiac reoperation in general has been infrequently discussed in the medical literature and has not yet appeared in the nursing literature. Yet reoperation presents a real challenge, accentuating some problems that are also associated with primary cases and posing some considerations that are unique to the reoperative situation. The objectives of this article are to discuss the reasons prompting reoperation for coronary revascularization, identify technical problems associated with reoperative coronary artery surgery, explore potential avenues for decreasing the need for reoperation, and discuss potential patient care problems in the immediate postoperative critical care setting.

Techniques in cardiac care: lasers, stents, and atherectomy devices.

Various new technologies are currently being investigated to treat cardiovascular disease less invasively than with conventional open heart surgery. Although lasers have been used in other health disciplines, their use in the cardiovascular field is relatively new. Even newer is the use of atherectomy devices and endovascular stents. It is important for the critical care nurse to be knowledgeable concerning these techniques in order to provide optimal patient care.

Laser angioplasty in peripheral vascular disease.

The use of laser energy to recanalize peripheral arterial vessels is a new and challenging alternative to more extensive surgical intervention. This exciting technique allows the critical care nurse to respond creatively to changing protocols and patient situations, establishing standards of nursing care for this patient population.

Intracoronary stents.

The use of balloon-expandable intravascular stents in atherosclerotic heart disease is currently being investigated as a feasible alternative/adjunct to more traditional methods of therapy, that is, coronary artery bypass surgery and percutaneous coronary angioplasty. Preliminary results of recent patient studies in the United States and Europe have demonstrated the ability of these stents to effectively maintain vessel patency and to potentially reduce restenosis rates both in peripheral and coronary arteries. Used in conjunction with other techniques (PTCA, laser, atherectomy devices), stents will hopefully increase the safety and long-term effectiveness of treatment of coronary artery disease by nonsurgical methods.

Clinical management using direct and derived parameters.

In the past, left heart function was estimated from the level of CVP, clinical information and chest x-ray; cardiac output was estimated from mixed venous oxygen saturation or content. These indirect assessments frequently led to incorrect conclusions and irrationale therapy. Currently, direct and derived hemodynamic parameters have been invaluable in the diagnosis, management, and prognosis in critically ill patients. Continuous mixed venous oxygen saturation monitoring affords yet another valuable parameter to facilitate optimal patient care outcomes.

The role of the cardiac sonographer in the evaluation of the heart transplant recipient.

The sonographer should have a basic understanding of the indications, surgical technique, survival rate, electrocardiographic findings, chest radiographic findings, and complications for orthotopic cardiac transplantation. The sonographer should also have a thorough understanding of the normal echocardiographic and Doppler findings in these patients and the possible echocardiographic and Doppler findings during acute early rejection. This article has presented those findings in a review form to enable the sonographer to consult the information presented before the echocardiographic and cardiac Doppler examination is carried out. In addition, a sample echocardiographic and cardiac Doppler worksheet has been provided.
