Cardiovascular emergencies: pericardial effusion and cardiac tamponade.

چکیده
On completion of this CE, the participant will be able to 1. Describe two cardiovascular emergencies for patients with cancer. 2. Describe medical management of the cardiovascular emergencies. 3. Discuss nurses’ role in the care of patients with cardiovascular emergencies. Cardiac tamponade is a life-threatening emergency that occurs when excessive fluid in the pericardial space, called a pericardial effusion, creates increased pressure in the pericardial sac that compromises the heart’s ability to fill and pump. Consequently, cardiac output decreases and systemic perfusion is impaired (Dietz & Flaherty, 1993; Hunter, 1998). The distinction between pericardial effusion and cardiac tamponade is important. Pericardial effusion is an anatomic diagnosis of abnormal pericardial fluid accumulation that has no hemodynamic consequences, whereas cardiac tamponade is a physiologic diagnosis of varying amounts of pericardial fluid that causes increased pressure and resultant hemodynamic consequences (Harken, Hammond, & Edmunds, 1997).

Background: Pericardial effusion and cardiac tamponade are the rare complications of peripherally inserted central catheters (PICC insertion) in extreme low birth weight infants. In this regard, paying attention to these complications is of utmost importance, because they can result in infant death. Case report: The case of our infant is a sa...
متن کاملComparison of the prevalence of pericardial effusion and cardiac tamponade after cardiac surgery with and without chest tube suction in patients referred to Chamran hospital, Isfahan
Background: Pericardial effusion is one of the most important complications of cardiac surgeries. Administration of a low-power suction to the mediastinal or pleural chest tube of patients helps better and constant drainage of pericardial or pleural secretions after surgeries. This technique might change the secretion and discharges of patients and might change the outcomes of surgeries. Metho...

Aims Tuberculous pericarditis is present in only one to two percent of the tuberculosis cases, i.e. considered rare. The disease is responsible for 4% and 7% of acute pericarditis and cardiac tamponade cases, respectively. Moreover, these conditions are associated with hazardous side effects. Thus, timely and precise diagnosis of the disease could prevent such complications. Case report We rep...

Hemodynamic instability is the major concern in surgical patients with pericardial diseases, since general anesthesia and positive pressure ventilation may precipitate cardiac tamponade. In advanced constriction diastolic impairment and myocardial fibrosis/atrophy may cause low cardiac output during and after surgery. Elective surgery should be postponed in unstable patients with pericardial co...

Pericardial effusion can cause cardiac tamponade physiology with resultant cardiogenic shock and death. Myelofibrosis, the replacement of marrow cavity by fibrous connective tissue, is a secondary complication of a group of disorders known as myeloproliferative neoplasms, which are clonal processes characterized by abnormal proliferative growth of one or more hematopoietic lineages. One consequ...
