Patients with traumatic fractures, especially those with multiple traumas, suffer from post-traumatic malnutrition to varying degrees due to more blood loss, and the situation is more serious when combined with cranio-cerebral or abdominal trauma, because they cannot eat. At the same time, because of the post-traumatic bed-ridden and reduced exercise, the original rhythm of life is disrupted, and the appetite is often reduced and does not want to eat. It is more likely to occur in elderly patients, people with weaker constitution or poor mental capacity, and it is especially obvious in a short period after trauma or surgery. The diet should be nutritious, with good color, aroma and taste, which can stimulate the appetite. Eat more tomatoes, bok choy, cabbage, radish and other vitamin C-rich vegetables as appropriate to promote scab growth and wound healing. The following points should be paid special attention to: 1, preoperative: (1) into high-calorie, high-protein, high crude fiber, vitamin and pectin-rich food, drink more water to ensure nutritional supply, and keep the stool open; (2) generally 12 hours before surgery to prohibit eating and drinking, in order to prevent vomiting during anesthesia, accidental aspiration and cause aspiration pneumonia, asphyxia and other accidents. (2) Postoperative (1) 6 hours after general anesthesia and epidural anesthesia, slowly transition to semi-fluid or general food, 4 hours after brachial plexus anesthesia. (2) After the doctor’s order to eat, you can start with a liquid and semi-liquid diet and transition to a normal diet, and any food can be made into liquid or semi-liquid. Fluid or semi-liquid can be: rice, oatmeal, noodles, vegetable soup, egg custard, minced meat or vegetable puree, etc. It is recommended not to drink pure milk powder (easy to bloat the stomach), and bone broth has limited effect on fracture healing and is not suitable to drink every day. (3) Prevention and control of constipation: early fracture often has constipation, more common in bedridden patients; it is advisable to eat more vegetables containing more fiber, eat some bananas, honey and other foods that promote defecation. (4) Bedridden patients are prone to urinary tract infections and urinary stones, so it is advisable to drink more water and urinate more often to prevent stones and infections (5) To quit smoking and alcohol: smoking affects wound healing ability and fracture healing; through X-ray monitoring, new bone growth after surgery in fracture patients was found to be significantly slower than non-smokers, and drinking Alcohol can increase the pain of the fracture injury, in addition, alcohol can cause disorders of liver metabolism and affect protein synthesis, which is therefore unfavorable to fracture healing. (6) Fracture patients do not need to “taboo”, there are no special restrictions on diet except for tobacco and alcohol. After a traumatic fracture occurs, the body is in a high metabolic state and the healing of the wound requires high quality protein. Although the patient cannot get out of bed, he still needs high protein, high sugar (diabetic patients should not take sugar-containing food directly), collagen, trace elements (copper, zinc, iron, calcium) and vitamin A and C-rich food, such as lean meat, pork liver, fish, shrimp, egg yolk, soybean products, carrots, fresh vegetables and fruits, etc., to supplement sufficient nutrition to promote wound healing and body recovery According to the latest research, fracture patients may need to supplement zinc, iron, manganese and other trace elements. Animal liver, seafood, soybeans, sunflower seeds and mushrooms contain more zinc; animal liver, eggs, beans, green leafy vegetables, wheat and bread contain more iron; cereals, mustard, egg yolk and cheese contain more manganese. Some drugs that promote bone growth have been studied such as bone peptides (more types), which may be helpful for fracture healing. Also some Chinese medicines that activate blood circulation and remove blood stasis may be helpful for fractures, consult your doctor if needed.
