Association between Preoperative Anaemia with Post Operative Mortality and Morbidity

Preoperative Anaemia is an important risk factor for post-operative morbidity and mortality and has been shown to be independently associated with adverse outcome after non-cardiac surgery.Several large observational studies, including over 600,000 patients, have confirmed the presence of an association between pre-operative anemia and poorer post-operative outcomesAnaemia is an independent risk factor for the preoperative and post operative patient in all types of surgery. Several studies had been done to asses anemia as independent risk factors in post operative outcome and also in patients with associated comorbidities also. meta analysis of various studies and comparison of result of metanalysis had been done and results interpreted as correction of anemia in all patients is important for better outcome. But specially in surgical patient preoperative correction of anemia should be implemented whenever possible for better surgical and patient outcome.
