Cannulation

Cannulation is the insertion and fixation of a cannula into a hollow or tubular organ for a long period of time.

The cannula is used for administering medications, drainage, taking samples and other purposes. It is a flexible plastic tube that is inserted into the lumen of the organ.

Cannulation is most often used in the treatment of kidney and urinary tract diseases. The cannula is inserted into the ureter or bladder. This allows for prolonged drainage of urine outward in case of urinary tract obstruction.

Cannulation can also be used in the treatment of gallstone disease. A cannula is inserted into the bile duct to drain bile if there is an obstruction.

The cannulation procedure is performed under local anesthesia. The cannula is fixed to the patient's skin using sutures or adhesive tape. Periodically it must be washed and replaced with a new one to avoid infection.

Thus, cannulation allows for long-term access and drainage of hollow organs when they are obstructed. It is an important treatment method in urology, surgery and other fields of medicine.

Cannulation is a medical procedure in which a catheter or cannula is inserted into a hollow organ or tube to perform medical procedures, withdraw fluids, or catheterize an artery. It can be used to diagnose or treat various diseases such as liver cirrhosis, liver failure, bile duct obstruction, pancreatic cyst, etc.

Cannulation is performed by qualified medical personnel under sterile conditions. Before the procedure, it is necessary to undergo an examination and obtain consent from the patient. Typically, cannulation is performed under local anesthesia or sedation.

To carry out the cannulation procedure, special catheters and cannulas are used, which can be of different sizes and shapes depending on the purpose of the procedure. Some catheters may have special tubing for testing blood or other fluids.

The procedure usually begins with anesthesia and preparing the patient for the procedure. The doctor then inserts the cannula through an available hole in the patient. The cannula is passed through various structures such as the esophagus, stomach or colon and reaches the desired organ. After achieving the goal, the cannula is fixed in the body using special clamps or glue. The procedure usually takes from a few minutes to an hour, depending on the complexity of the situation.

After the procedure is completed, the doctor removes the cannula and checks the risks of possible complications. The next step may be to further diagnose or treat the problem caused by the cannulation procedure. Many patients experience some discomfort after cannulation, but this discomfort is usually temporary and resolves within a few days.

The advantage of cannulation is its flexibility and accuracy in obtaining the necessary data or administering drugs. The cannulator can also be used several times for other procedures, which reduces the cost of treatment and reduces the number of patient visits to the clinic. However, the procedure may carry some level of complications if it is performed incorrectly or used in inappropriate cases. Cannulators must be well trained to ensure patient safety and minimize the risks of complications. Cannulation may also cause discomfort in some patients, especially if the procedure was performed without anesthesia.
