Final answer:
Enemas involve introducing liquid into the large intestine to clear feces. A low enema liquid is introduced 3 to 4 inches into the anus, while for a high enema, it's 6 to 12 inches. The procedure should be done gently and with medical discretion.
Step-by-step explanation:
An enema is a procedure that involves introducing a liquid into the large intestine through the anus to encourage bowel movements and clear the bowel of feces. In the context of high and low enemas, the 'high' and 'low' refer to how far the liquid should be introduced into the colon. For a low enema, the solution is typically administered only into the rectum and sigmoid colon, whereas a high enema aims to reach further into the descending colon.
For a low enema, the enema tip is usually inserted 3 to 4 inches into the anus. However, when performing a high enema, care must be taken to insert the enema nozzle 6 to 12 inches to allow the liquid to reach higher into the colon. It should be done gently to avoid injury and ensure the patient's comfort. Medical professionals should always use discretion based on the patient's condition and anatomy.
