Improving the adverse changes in cardiac autonomic nervous control during laparoscopic surgery, using an intermittent sequential pneumatic compression device.

Background: The creation of positive pressure pneumoperitoneum (PP) may lead to adverse cardiovascular effects during laparoscopic operations. It can also lead to increased sympathetic cardiac activity, that might have serious consequences. We hypothesized that by reversing the hemodynamic effects, the use of intermittent sequential pneumatic compression device (Lympha-press) on the lower extremities would lead to improved cardiac autonomic control.
