Food is the most important thing for people, but many people are confused about “eating” during surgery. What is water fasting – how long is it? What’s a crumb-free diet – what’s that? We’ve heard a lot about this, but we don’t know what to do, so let’s sort out how to “eat” during surgery. First of all, when can you eat and when can not eat. Patients who need anesthesia will be told to “fast from water” the day before surgery. This is because the muscles of the whole body are relaxed during surgery, so if you eat something, it is likely to reflux into the trachea and cause serious consequences such as asphyxiation. Generally speaking, adults should fast for 8 to 12 hours before general anesthesia surgery and 4 hours before water, if the surgery is the next morning, the night before dinner, do not eat anything else, you can drink some water before bed, but do not drink too much. In the case of abdominal surgery, there is also the possibility of bowel cleansing the day before. As instructed by the nurse, an enema or laxative is given to empty the intestines. Once you are clean inside and out, you can effectively avoid infection during the surgery. After the operation, when the stomach can make the “gurgling” sound again, and after the exhaustion, that is, farting, you can eat a small amount of liquid food, and then the next day you can eat a small amount of semi-liquid food. What is a liquid diet, what is a semi-liquid diet, and what is a non-crumb diet. I often hear the nurse practitioner say that you should eat liquid food first, then semi-liquid food, and try to eat non-crumbly food before surgery. In the end, what is a liquid diet, what is a semi-liquid diet, give you a list of good. Usually said no residue diet, that is, liquid food, it will not produce a lot of food residue, not easy to cause wound infection, in addition, liquid food is better digestion, the gastrointestinal stimulation is also small, abdominal surgery patients, after the exhaustion of the best first day to eat a liquid food. Specifically, the liquid food is all “soup”, rice porridge rice grains are fished out, egg soup eggs are fished out, chicken soup chicken are fished out, the rest is soup water “liquid food”. Soup and water without solids in it can be considered as liquid food. If you need to eat liquid food for a long time, you have to follow the doctor’s instructions and drink special nutritional solution to ensure your life needs. Semi-liquid diet as a “upgrade” of the liquid diet, you can leave some easily digestible solids, millet, boiled beans, or egg custard, but meat or try to put a little less, after all, meat is more difficult to digest, and post-operative digestive function has not fully recovered. What foods are high in protein? What should I eat? I often hear doctors say that eating more high protein helps the wound recover. What should be eaten, the following can refer to the reference. The protein content of the liquid food is relatively high milk, soy milk, if it is soy milk, be sure to fish the residue clean. Semi-liquid food can eat more egg custard, can also be supplemented with protein.
