Surgery - Nutrition for surgery patients
Nutrition is crucial to the health of surgery patients. Providing timely nutritional support can minimize acute catabolism and skeletal muscle weakness caused by metabolic loads. This is a prevalent element that impacts the outcome of surgery patients. The incidence of pre-existing malnutrition is high and increases with age. Patients with high nutritional needs, such as those with severe burns, sepsis, intestinal fistulae, advanced cancer, or immunosuppression, may require additional support to prevent excessive acute catabolism due to metabolic demands. Assessment of nutritional status.
All patients should be evaluated for nutritional status. Various methods can be used: • BMI (weight/height in kg/m²). Relatively insensitive to all but major malnutrition. A BMI of 18-25 is considered normal, while <18 indicates underweight and>30 indicates obesity.
• Thickness of the triceps skinfolds. This test is simple and effective for measuring body fat, which can indicate chronic nutritional condition. • Strong grip. Simple, repeatable index of lean skeletal muscle. Serum albumin. Poor predictor of acute nutritional status. Responds slowly to dietary supplementation and is influenced by several circumstances.
• Serum transferrin. A reliable indicator of acute state and response to treatment. Not widely used. Effects of protein-calorie deficiency.
Decreased neutrophil and lymphocyte function. Albumin production is impaired. Impaired wound healing and collagen deposition. Skeletal muscle weakness, known as 'critical illness myopathy,' can lead to respiratory and gastrointestinal problems.
• Micronutrient deficits can cause particular clinical symptoms.
Types of Nutritional Support
• Oral supplements. Examples of high-calorie, high-protein supplements are Fortisip®, Calshakes®, and Ensures®/Enlives®. For nutritional supplementation, oral administration is always the preferable method. It promotes healthy GI flora and reduces the chance of problems following surgery. • Nasogastric (NG) or nasojejunal feeding. Often used in conjunction with oral supplements. Sometimes administered overnight to reduce appetite suppression during the day.
• Surgically implanted feeding tube (gastrostomy or jejunostomy). Not commonly used. This is reserved for people who have a functioning GI tract but cannot take via the oropharyngeal route.
• \tParenteral nutrition. It may be central or peripheral.
