摘要:

This article describes the interrelated processes and homeostatic controlling mechanisms of hemostasis and fibrinolysis. Hemostasis involves platelets, blood vessels, and coagulation proteins. Primary hemostasis is dependent on platelet adhesion, activation, secretion, and aggregation. Secondary hemostasis consists of intrinsic activation, extrinsic activation, and the common final pathway. Fibrinolysis results in clot dissolution and is initiated endogenously as plasminogen is converted to plasmin.

摘要:

This article discusses the current approach of using thrombolytic therapy as treatment for acute myocardial infarction (MI). The etiology of acute MI is reviewed along with recent research findings from definitive clinical trials. The mechanism of action of thrombolysis is described, and the available and investigational thrombolytic agents are compared. Complications of thrombolytic therapy and assessment indicators of reperfusion are presented. Key aspects of the nurse's role in the management of thrombolytic therapy are highlighted.

摘要:

Complete and accurate documentation is necessary for optimal nursing care of patients receiving thrombolytic therapy for acute myocardial infarction. A tool is necessary to facilitate smooth transition and consistent patient care in communication between the emergency department and coronary care unit. The authors have developed a simple flow sheet to be used at the bedside for a clinical research protocol involving thrombolytic therapy.

摘要:

Pathologic cellular changes that begin with ischemia may be worsened when an occluded artery is recannulized. Thrombolytic agents—the standard treatment in acute MI—may contribute to these cellular events, collectively termed “reperfusion injury.” Highly toxic chemical moieties called oxygen free radicals participate in the injury process. This article discusses the concepts of ischemia, reperfusion, and reperfusion injury and explains the role played by oxygen free radicals in the generation of reperfusion injury. Also described is the use of oxygen free radical scavengers to prevent this injury.

摘要:

Carpenito's bifocal clinical nursing model enables the clinician to address the spectrum of clinical possibilities and problems associated with patients receiving thrombolytic and anticoagulant agents. Through correct application of nursing diagnoses, collaborative problems, and referrals, a global and multidisciplinary approach to patient care is achieved.

摘要:

The development of cardiac catheterization procedures in the pediatric population has evolved from diagnostic in nature to present day advanced technology and interventions. A complication of vessel occlusion secondary to large catheters, length of procedures, and patient size requires immediate intervention. The advent of thrombolytic agents has provided a highly effective mode of treatment in restoring circulation. The use of streptokinase, its efficacy, side effects, and nursing management are discussed.

摘要:

Continuing education of nurses in therapeutic advancements poses a challenge to nurse educators and managers. The competency-based educational method is a way to prepare nurses and subsequently evaluate performance based on derived standards. In this article a competency-based education approach to the use of thrombolytic therapy in acute myocardial infarction is examined.

摘要:

This article describes a case study of a 42-year-old man who received recombinant tissue plasminogen activator (rt-PA) therapy for treatment of an acute myocardial infarction. The case study describes the nursing management of this patient beginning with the initial assessment for candidacy for rt-PA through the hospital course and follow-up after discharge.

摘要:

Computers are serving intensive care patients by simplifying and improving the accuracy of data acquisition, facilitating communications, storing and organizing patient records, and providing expert suggestions. The future will bring many changes in the way nurses practice in intensive care. The computer should be considered an evolutionary tool to help effect these changes.

摘要:

The patient who is hospitalized for medical management of lymphedema presents complex issues for the nurse. Developing a care plan that will direct nursing interventions during the acute phase demands an understanding of the chronicity of the problem. The patient will require considerable teaching and support before discharge. This article provides the reader with concepts applicable to this debilitating condition.
