Introduction
During a colonoscopy under general anesthesia, the patient lies on their left side while the endoscope is inserted through the anus to examine the rectum, sigmoid colon, descending colon, transverse colon, and ascending colon. The entire intestinal condition is simultaneously displayed and observed on a monitor. It is recommended that colonoscopies be performed at正规 hospitals by qualified physicians.
Generally, a general anesthesia colonoscopy refers to a procedure in which a colonoscope is used to examine the internal condition of a patient's body after administering anesthesia. The specific steps are as follows:
1. Verify the patient's information before the examination and confirm the indications and contraindications.
2. Administer general anesthesia to the patient.
3. Position the patient on their left side with knees bent to expose the buttocks.
4. Place a treatment drape under the patient's buttocks and position a kidney basin beside them.
5. Lubricate the anal region with silicone oil, then perform排气 (gas release).
6. Insert the colonoscope through the anus into the rectum, sigmoid colon, descending colon, transverse colon, ascending colon, and other areas, observing the images displayed on the monitor.
7. Remove the colonoscope, wipe the patient's buttocks dry, and complete the examination.
After the procedure, it is recommended to consume light and easily digestible foods. Colonoscopy should be performed at a正规 (reputable) medical facility by qualified physicians.
