Why is there less blood loss with robot-assisted surgery?
Robot-assisted surgery using the da Vinci system is minimally invasive. It operates through a few small incisions and tissue damage is minimal. Obviously small incisions mean considerably reduced blood loss compared to the large incision method used in open surgery.
There is also another reason for less blood loss in robot-assisted surgery. The surgeon has a better visibility on blood vessels than in open surgery or even laparoscopic surgery due to the high definition cameras and the magnified 3D view. Because of the high quality of visualization and the precision of the robotic arms movements the surgeon is in an increased control regarding the blood vessels and is more able to avoid injuries and damage to the blood vessels.
A better view of the surgical field is also provided by the inflation of the abdomen with gas (usually they use carbon dioxide). The gas pressure compresses the blood vessels, that is another cause for a decrease in blood loss.
Less blood loss in robotic surgery helps you avoid infections and further complications and lowers the need for blood transfusion to almost 0%.
