Abstract:
» Initial screening for malnutrition can be initiated with a fibrinogen-albumin ratio threshold <11.7.» Protein supplementation to goal (1.2-1.9 g/kg), along with essential amino acid augmented with beta-hydroxy-beta-methylbutyrate and resistance training have shown benefit, especially in sarcopenic patients.» Omega-3 and omega-6 polyunsaturated fatty acid supplementation has a strong antioxidant role and gain of muscle mass.» Supplementation with adenosine triphosphate and magnesium sulfate provides an avenue to decrease postoperative pain and opioid consumption.» Motivational interviewing and multidisciplinary teams to achieve preoperative weight loss >20 lbs in morbidly obese patients can decrease complication rates.
