OBJECTIVE: To compare thoracic and abdominal cavity volumes during abdominal CO(2) insufflation and abdominal wall lift (AWL) conditions. STUDY DESIGN: In vitro cadaveric study. ANIMALS: Mature medium-to-large breed fresh canine cadavers (n = 6). METHODS: Each cadaver was imaged with computed tomography (CT) under baseline, abdominal CO(2) insufflation, and AWL conditions. Measurements of thoracic and abdominal cavities were performed for each condition using image-analyzing software. Resulting volumes for each cadaver were converted to percent change from baseline to normalize the data. The t-tests were used to compare percent changes of both thoracic and abdominal volumes. RESULTS: Thoracic volume significantly decreased from baseline during CO(2) insufflation (P < .01). No significant difference in thoracic volume occurred with AWL when compared with baseline. Abdominal volume increased by 80% with CO(2) insufflation (95% CI: 56.4-107.0%) but only 25% with AWL (95% CI: 12.3-37.8%). CONCLUSIONS: Abdominal CO(2) insufflation results in decreased thoracic volume when compared with baseline. AWL preserved thoracic volume similar to baseline. Abdominal volumes achieved with abdominal CO(2) insufflation are significantly greater than those attained with AWL.
