Essay On Pulmonary Embolism

Good Essays

Various studies has been presented many methods to prevent pulmonary embolism in high-risk patents which mostly focus on using of inferior vena cava filters, and anticoagulation. However, contradictory results are suggested within this research because only a certain type of inferior vena cava filters are examined, for example, prophylactic inferior vena cava filters. Dazley et al. (2012) shows the efficacy of propyl lactic IVC filters in preventing the development of venous thromboembolic event in patients undergoing surgery, while the other study proposes the different result. To understand how IVC filters and anticoagulation effect on high-risk patients. This paper study Dazley et al.’s (2012) research to express better understand how …show more content…

Small embolism that stuck in the peripheral branches of the pulmonary artery are clinically silent and may go unrecognized. People with moderate-sized emboli often present with breathlessness accompanied by pleuritic pain, apprehension, slight fever, and cough productive of blood-streaked sputum. Patients with massive emboli frequently specific with sudden collapse, crushing substernal chest pain, shock, sometimes loss of consciousness; so massive emboli often are mortal (Porth, 2011).
Spinal cord injury is the serous risk that cause VTEs and lead to PE, so Dazley et al. (2012) research concentrations on the efficiency of prophylactic IVC filters PE in patients undergoing major spinal injury to prevent PE. Pulmonary embolism has been present in up to 12% of patients undergoing spine surgery and 2% fatal rate (Dazley et al., 2012); therefore, patients diagnosed with PE require prompt and aggressive treatment with anticoagulation such as low-dose heparin and low molecular-weight heparin. However, the anticoagulation pharmacologic agent can cause bleeding problems, up to 67% (Dazley et al., 2012), and the most bleeding complication in spinal cord surgery is compressive epidural hematomas; therefore, the bleeding complications become worst in patients who cannot be treated with anticoagulation. Their effects require immediate surgical intervention and still may leave patients with permanent neurological deficits in as many as 37.5% of patients ((Dazley et
