ABSTRACT

Objective To investigate the therapeutic effect of intravenous bloodletting combined with low molecular weight heparin in the treatment of chronic pulmonary heart disease and hyperviscosity in plateau area. Methods 84 patients with chronic pulmonary heart disease complicated with hyperviscosity from plateau area were randomly divided into the control group (40 patients) and the observation group (44 patients). In the two groups, on the basis of routine treatment (anti-infection, anti -asthma, oxygen inhalation, and correction of heart failure), the observation group was further given intravenous bloodletting combined with low molecular weight heparin calcium. The changes of respiratory rate, content of venous hemoglobin, hematocrit and arterial partial pressure of oxygen before and after treatment were monitored and statistically analyzed. Results After treatment, the respiratory rate, content of hemoglobin, hematocrit and PaO2 in the observation group were significantly better than those in the control group (P＜0. 0l). Conclusion Intra-venous bloodletting combined with low molecular weight heparin is more effective than conventional treatment method in the treatment of chronic pulmonary heart disease and hyperviscosity in plateau area.
