The process and matters needing attention of gastroscopy

With the continuous improvement of gastroscope technology, the application scope is also expanding. Simple operation, no injury, no pain for patients and no special treatment after operation.

1. Before surgery

Eliminating nervousness is conducive to better cooperation with the exam. Preoperative fasting 12 hours, water deprivation for 2 hours, make the stomach empty, to prevent food from being sucked into the trachea when vomiting, and also facilitate examination.

2. It happened during the surgical operation.

The patient lies on his side with his legs bent. Swallow when entering the mirror, don't hold your breath, you can take a deep breath or a deep breath, which can relax your body and relieve discomfort such as nausea and vomiting. After taking a break from the mirror, there may be numbness in the throat, which is a reaction caused by anesthetic and usually disappears naturally after half an hour.

3. After the operation

Pay attention to rest after operation, continue to fast, 1 hour do not drink water to prevent coughing, and drink appropriate amount of water after anesthesia disappears.

Local anesthesia is used for anesthesia, that is, spraying 2% dicaine or 2% serum caine, and spraying the medicine three times when the patient opens his mouth and makes an "ah" sound. After each spray, the patient swallows the medicine left in his mouth to anesthetize his throat. Paste is also used, which is contained in the mouth to make the medicine stay in the throat and naturally flow into the esophagus to play a local anesthetic role.

After the examination, the patient sat up and spit. Because some air was injected during the examination, although it was sucked out when the mirror was removed, some people still felt abdominal distension and a lot of belching.
