Anemic patients undergoing surgery are likely to receive blood transfusion, increasing morbidity and mortality. Prevalence of anemia in cardiac surgical patients are studied extensively, however its burden in RVHD is lacking. This study attempted to investigate the prevalence of preoperative anemia in RVHD and its effect on blood transfusion, morbidity and mortality in patients undergoing valve surgery. Methods: This is a retrospective observational study conducted at a tertiary care hospital in Nepal. We considered 340 patients who underwent Rheumatic valve replacement surgery from 2014 January to December 2016 and data on their socio-demographic and clinical characteristics were extracted from the patient’s records. The analyses meeting the study objectives were conducted using IBM SPSS v25 for Windows (IBM Statistical Package for Social Sciences, 2015IBM Corporation, New York, United States). Results: The prevalence of no anemia, mild, moderate, and severe anemia was 34.1%, 57.7%, 39.6%, 2.5%, respectively. The units of Red Blood Cell used for transfusion were 1.2 units, 2.0 units, 2.3 units, and 1.6 units in patients without anemia, and those with mild, moderate and severe anemia respectively. The incidence of reexploration was higher in patients with severe anemia as compared to the non anemic with an incidence of 66.6%. A proportion of the patients with no anemia, mild, moderate and severe anemia with less than 7 days stay in the intensive care unit were 89%, 82%, 84.7% and 100% respectively. The length of hospital stay more than 10 days was seen in 58.9%, 71.6%, 63% and 100% in patients with no anemia, mild, moderate and severe anemia. An overall incidence of mortality in anemic patients was 11% while in non anemic patients was 5.3%. Conclusions: The prevalence of anemia was high in the Nepalese patients with Rheumatic valvular heart disease planned for elective surgery. There was an increased incidence of blood transfusion, longer hospital stay, and increased mortality in anemic patients compared to their non anemic counterparts.展开更多
