What is an enema? Correct enema operation

Enema is a way of delivering medication into the body through the anus. There are many types of enema. Cleansing enema is very common and can be used to clean the intestines before surgery to avoid infection during surgery. It can also reduce abdominal bloating or abdominal discomfort after surgery.

Cleansing Enema

Cleansing enema is a procedure in which 500-1000 ml of 0.1-0.2% soapy water or clean water is passed through the anus and slowly poured into the colon from the anal canal through the rectum. This helps the patient expel feces and accumulated gas, prevents the relaxation of the anal sphincter after anesthesia from causing feces to contaminate the operating table, and increases the chance of infection. It can also reduce postoperative abdominal distension.

Method of action

operate

Take NS500ml and insert it into the disposable infusion set after routine disinfection

, remove the sterile needle; take a disposable suction tube (14-16﹟), apply an appropriate amount of lubricant on the front end, connect it to the front end of the infusion set, and exhaust the gas in the rectum; gently insert the disposable suction tube into the rectum 10-15cm and fix it, loosen the speed regulator to allow the liquid to flow in slowly.

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: 500ml of 0.1% soapy water, 5-10L of normal saline, liquid temperature 38-41℃.

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.

Cleansing Enema

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.

Enema Types

Depending on the purpose of enema, it is divided into cleansing enema and retention enema. Cleansing enema is to remove food residues or toxic substances in the intestines through enema. Retention enema is often used to treat various diseases. It allows the injected liquid to remain in the body for a certain period of time so that the drug can be fully absorbed in the intestine and take effect. Before enema, you should do a good job of ideological work on the patient, strive for the patient's cooperation, let him relax as much as possible and eliminate tension.

The patient lies on his left side with his body naturally bent and his buttocks exposed. The operator stands on the patient's back, selects a suitable sterile enema device, wears sterile gloves, adjusts the leak bottle on the top of the enema device to a certain height, injects the liquid used for enema into it, and after the gas in the enema tube is discharged, clamp the upper end with a vascular clamp. Then, apply paraffin oil to the anal tube at the lower end of the enema device and slowly insert it along the anus for about 10 cm. Then, release the vascular clamp on the upper end and the liquid will slowly be injected into the intestine. The amount of fluid infused should be determined according to the specific condition and purpose. If used for colonoscopy, a cleansing enema is used, and the amount of enema should be sufficient to ensure that all food residues in the intestines can be discharged.
