It is usually possible to eat and drink immediately after arteriovenous fistula surgery. Arteriovenous fistula surgery does not affect intestinal function, so you can eat and drink normally. However, arteriovenous fistula surgery in the cerebrovascular and other special parts of the surgery requires general anesthesia, need to wait for the anesthetic drugs to completely disappear before eating and drinking. Postoperative patients should also pay attention to drink more water, which is conducive to promoting the patient’s metabolism, and at the same time is conducive to promoting blood circulation, which can avoid the local blood volume decrease and thus lead to the formation of thrombus. After surgery, patients should pay attention to rest, pay attention to surgical wound care, and eat a balanced diet to ensure adequate nutritional intake. It is recommended that patients should pay careful attention to the operation area, always observe the physical condition, and pay attention to a healthy diet. And go to the hospital for regular checkups.
