What a needle is?
Veress Needle is also a surgical tool called non -sized or pneumo needle. It is a needle with a spring used in many laparoscopic operations to inflate the abdominal cavity before inserting a skeleton tool. This type of needle is produced in two different sizes, with a spring -tipped tip that pulls into a sharp outer needle when it is inserted into the abdominal cavity. Once the peritoneal cavity is achieved, the blunt tip appears and carbon dioxide is added to the abdominal cavity, allowing the laparoscopic procedure to start. Damage to nearby blood vessels or intestines is possible unless the tool is inserted at the correct angle. The piercing of the intestine can cause postoperative infection called peritonitis. Inserting into the blood vessel can cause excessive bleeding or cause air pockets to form in the container. Right common iLiac artery, lower epigastric Cévals and distal aorta are most often damaged unless the needle is used correctly.
The correct use of the Veress needle includes careful placement of the patient at the beginning of the laparoscopic procedure. Before the surgeon inserts the Veress needle, the patient will be placed in the position of Trendelenburg. The abdomen is elevated and the patient is immobilized before the introduction of Veresshe needle towards the pelvic area at an angle of 45 degrees into the spine. If the needle deviates from the expected angle of insertion or is inserted perpendicular to the abdomen, there may be serious injury.
The surgeon can verify the correct positioning of the needle Veress by performing several simple tests. First, a physiological solution is added. When it is correctly placed, the surgeon will not be able to aspire any needle fluid. If the blood is taken from Needle, it may indicate that it has pierced the blood vessel. Fekal matter or urine can also be aspired from the incorrectly placed Veress needle.
After the surgeon is reasonably sure that the needle is located in the right place, the valve will be connected to the tool. Oxide uhBowling is slowly pumped into the abdominal cavity to inflate the area for optimal visibility during surgery. Then the surgeon performs another test to ensure the correct placement of the needle. During this test, the carbon dioxide valve is briefly closed, causing air to escape the Veress needle with a slight syring sound. If there is no hissing sound, the needle should be removed and moved.
