Inserting the veress needle
Perform the syringe test, etc. to confirm that the veress
needle is properly inserted into the abdominal cavity.
Improper insertion may result in complications such as
subcutaneous emphysema or gas embolism.
1.
Insert the sterilized veress needle into the abdominal cavity as shown in
Figure 5.1. Confirm that insertion is performed correctly.
Figure 5.1

Insufflation
Adjust the flow rate setting in accordance with the abdominal
cavity volume. For children, whose abdominal cavity volume
is small, insufflation at a high flow rate may cause the
abdominal pressure to exceed the set pressure.
The table below shows the flow rate when nothing is
connected to the insufflation connector. Flow resistance
varies depending on the connected instrument. Accordingly,
the actual gas flow rate may not conform to the figures in the
table. In addition, when the medical gas pipeline is
connected, the actual gas flow rate may not conform to the
figures in the table.
