Does brachial plexus anesthesia needle need water fasting

Brachial plexus anesthesia is different from general anesthesia in that water fasting is required before surgery, but generally not required after surgery. The details are as follows:

Preoperative: 1. Anesthesia may lead to anesthesia poisoning, which may cause uncomfortable symptoms in patients, increase the contents of the stomach, and easily lead to vomiting, back aspiration, asphyxia, etc. 2, if brachial plexus anesthesia is not ideal, can be temporarily changed to general anesthesia, intubation is required at this time, if the patient has a large amount of stomach contents, it does not meet the operating standards of general anesthesia. Therefore, even with brachial plexus anesthesia, water fasting is still required before surgery.

Postoperative: Generally speaking, there is no need to fast water after brachial plexus anesthesia, because brachial plexus anesthesia is mainly to inject local anesthetic drugs around the brachial plexus nerve stem, so that the local consciousness is lost, postoperative patients are generally awake, able to eat and drink their own, so there is no need to fast water after surgery. After brachial plexus anesthesia need to eat light diet, do not eat spicy stimulating food, avoid alcohol and tobacco adverse stimulation, in addition, you can use some antibiotics under the guidance of the doctor, avoid the occurrence of infection, pay attention to rest, do not strenuous activity tired.
