The assessment of nutritional status of surgical patients is important as malnourishment is a risk factor for morbidity and mortality.1 The pre operative status of a patient can be assessed with anthropometric measurements and laboratory parameters. Serum albumin is one such easily accessible parameter. This study evaluated pre operative serum albumin levels as predictor of post operative morbidity and complications in the patients undergoing elective surgeries and assessed association between preoperative serum albumin concentration and surgical outcomes. Method: This is a prospective observational study conducted between July 2017 and July 2019, on 200 patients undergoing elective major surgeries at a tertiary care centre. Result: The mean serum albumin levels of patients with complications (3.09 ± 0.62mg/dl) was significantly lower compared to the mean serum albumin levels of patients without complications (3.77 ± 0.83mg/dl) as per Student t–test. Conclusion: Proper assessment of pre– operative serum albumin can be used to predict the post–operative outcome and complications in major surgeries and thereby prevent it.
