Postoperative dietary considerations for intracranial aneurysms are as follows: 1. Craniotomy: Postoperative meals are often delayed, to be carried out after the patient is fully awake. Because of the large trauma, it is often necessary to advance a simple fluid diet on the 2nd-3rd day after the operation. If the patient’s preoperative state is not good, this time often can not eat, to nasal feeding, but also with the digestive tract mucosal protection drugs; 2, intervention: some of the treatment of the unbroken is relatively simple, 2 hours after the operation to wake up, after anesthesia, 3-4 hours can be a normal meal, 1-2 days can be discharged; if the aneurysm broke depends on the patient’s preoperative state, the amount of bleeding. If the amount of bleeding is small, simple headache, usually after surgery anesthesia awakening, and then 1-3 hours later to encourage the patient to enter the liquid diet, diet is not affected; this kind of patient more into the liquid diet and drink more water, can fight against vasospasm; if the patient can’t eat and drink by themselves, but also for nasal feeding; nasal feeding is mainly based on rehydration, in order to fight against postoperative vasospasm, or the patient’s bleeding produced by the vasospasm. If the patient is able to eat, regardless of the type of surgery, start a liquid diet as soon as possible, and then slowly transition to a normal diet if the patient is in good condition, or nasogastric feed as soon as possible if the patient is unable to eat.
