Objective

To record and compare the frequency of organ penetration after insertion of a Veress needle (VN) in 6 different intercostal spaces (ICS) for creation of pneumoperitoneum in canine cadavers.

Study Design

Descriptive study.

Animals

Canine cadavers (n = 15).

Methods

In 15 cadavers positioned in dorsal recumbency, VN insertion in the right and left 8th–10th ICS was performed, the abdomen insufflated, and VN position and any visceral penetration recorded. The frequency of viscus penetration was assessed in all insertion sites.

Results

In cadavers, the right 9th ICS was associated with the lowest number of organ penetrations after VN insertion.

Conclusion

In cadavers, the position associated with the lowest frequency of penetrating any intraabdominal structure was the 9th ICSon the right side.
