Doctor Byhahn and associates from Frankfurt have evaluated carefully the hemodynamic effects of thoracic cavity CO2 pressurization used for lung compression needed to render optimal visualization of the internal thoracic artery (ITA) during endoscopic robotic harvesting. Although numerous surgeons have reported endoscopic ITA harvesting, few reports have highlighted usage of new robotic methods or have evaluated physiologic effects during thoracic insufflation. The current authors concluded that during single lung pressure insufflation at 10 to 12 torr, oxygenation remains unaffected; however, both arterial CO2 levels and heart rate rise. Nevertheless, both the arterial blood pressure and PaCO2 still remain at . . . [Full Text of this Article]
