How do you hold a Veress needle?

You should also know how to put a needle into a Veress.

It is important to determine the length of Veress' needle needed to reach the peritoneal cavities. Non-obese patients should grasp the Veressneedle above the measured distance, and insert through the incision at a 45Adeg angle towards the pelvis cavity. You should feel two apopsa.

What is the Hasson technique? Hasson first described the open technique in 1970. This technique involves making a small incision through the umbilical cord under direct visualization. Then, a blunt trocar is introduced. The pneumoperitoneum can then be quickly created.

This begs the question: How does a Veress-needle work?

The outer cannula houses an inner stylet that is spring-loaded. The dull, inner stylet will spring forward when the tip enters any space, such as the peritoneal cavities. The Veress needle is used to inject carbon dioxide into the space. This creates a pneumoperitoneum.

How do you develop Pneumoperitoneum?

The first step in the procedure is to safely insert the trocar and obtain pneumoperitoneum. By inserting a Veress through the abdomen wall within the peritoneal cavity, you can usually obtain closed pneumoperitoneum.
