The surgical risks of lobectomy mainly include anesthesia risk, bleeding risk, nerve injury risk, infection risk and other risks. 1. Anesthesia risk: Lung lobectomy is a general anesthesia surgery, which has certain requirements on patients’ basic cardiopulmonary function. Anesthesia will inhibit blood vessels and nerves, triggering the lowering of blood pressure, which may lead to the insufficiency of blood supply to the heart and the brain, and induce the disease. At the same time, anesthesia may also cause allergy, and anaphylaxis may occur in severe cases. 2. Bleeding risk: the lung lobes contain abundant blood vessels and have large blood vessels directly connected with the heart, once the blood vessels are damaged, hemorrhage and hemorrhagic shock may be triggered. 3. Risk of nerve damage: There are a large number of nerves in the chest wall and intercostal space, so the surgery may damage the nerves and cause local numbness and discomfort. 4. Risk of infection: Lobectomy leaves large wounds in the chest cavity and chest wall, and these wounds are susceptible to infection. 5. Other risks: Some hidden diseases not found before surgery may be induced due to surgical traumatic stress, especially some hidden heart diseases, etc., which may be life-threatening in serious cases.
