Purpose of cleansing enema

Cleansing enema is a common treatment method. It mainly involves choosing some medicines or soapy water and injecting them into the colon through the anus. This can promote defecation and the discharge of some gas accumulated in the body. The reason for doing this is, on the one hand, to avoid contamination of the operating table after surgery, which can easily lead to increased infection, and on the other hand, to avoid abdominal distension after surgery. Let's take a look at this aspect below.

Purpose of cleansing enema

(1) Keep the intestines empty before surgery to prevent vomiting during anesthesia.

(2) Avoid intestinal expansion, which may affect intestinal exposure and cause accidental injury.

(3) Keeping the gastrointestinal tract empty can reduce postoperative gastrointestinal bloating, help restore gastrointestinal function, and prevent intestinal adhesion.

(4) Some gynecological tumors, such as ovarian malignant tumors, are prone to invade the intestines. It is possible that part of the intestine will be removed during surgery. Therefore, cleansing enema is also a preparation for intestinal surgery.

(5) Prevent the expanded intestine from squeezing the surgical site and reduce postoperative pain and bleeding.

advantage

Enema uses a disposable suction tube, which is longer than the anal canal, has a thin lumen, and a smooth and porous front end. It has little irritation to the mucosa during insertion, and the patient feels no pain and has a strong tolerance. The suction tube can be inserted deeper, and the drug solution is not easy to flow out. In this way, it stays in the intestinal cavity for a long time, fully softens the feces, defecates a lot, defecates thoroughly, and keeps the sheets clean and dry. The decrease in bowel movement frequency reduces the number of intubations, alleviates patient pain and improves patient satisfaction. Disposable suction tubes are easy to replace, inexpensive, and simple to operate, and are worth promoting.

Supplies: Same as bulk non-retention enema. Enema solution: 500 ml of 0.1% soapy water, 5 to 10 L of normal saline, liquid temperature 38 to 41°C.

method

1. The method is the same as for large-volume non-retention enema.

2. First, pour in 500 ml of 0.1% saline to stimulate intestinal peristalsis. After the solution is discharged, irrigate with isotonic saline. Repeat several times until clean liquid without fecal residue is discharged.

The purpose of cleansing enema is to stimulate intestinal peristalsis, soften and clear feces, eliminate intestinal gas, relieve abdominal distension, clean the intestines, and prepare for surgery, examination, and delivery. However, due to the large amount of enema fluid, the anal canal is thicker, and the fluid enters quickly, which greatly stimulates the intestine. After the tube is removed or even during the operation, the urge to defecate occurs, and the enema fluid is quickly expelled. A small amount of hardened stool may also be seen during the operation, and the purpose of enema cannot be achieved.
