The VNPD was measured as the distance traveled by the VN between the subcutaneous tissue and the perforation of the peritoneum on the basis of audible clicks and visible feedback from the VN.

The VNPD was less at the 9th ICS than at the preumbilical, paraumbilical, and subumbilical sites. The maximal magnitude of change was 7.4 mm. Veress needle B (with a low spring rate, lower forces, and a back\u2010cut bevel design) penetrated farther than VN A (with a high spring rate, high forces, and a lancet\u2010type bevel) at 3 of 4 insertion sites.
