A client is receiving low–molecular-weight heparin to prevent thromboembolic complications. the nursing student asks the instructor the reason why this treatment is given instead of heparin. what is the instructor's best explanation of the rationale for lmwh over heparin?

Respuesta :

Low molecular weight heparin is associated with less thrombocytopenia than the normal heparin. Low molecular heparin also prevent unnecessary bleeding since it is not as strong as the normal heparin. Low molecular weight heparin are derived from smaller polysaccharide chain and their effect is more predictable than the normally unfractionated heparin. It also help treat deep venous thrombosis, which is commonly associated with prolonged sitting and standing. It is also used to treat pulmonary embolism especially the more massive one. However, care must be observe in using it since some patients elicit allergic responses to it.
