Minimally invasive pulmonary nodule surgery is performed using thoracoscopy, which is very minimally invasive and basically enables discharge from the hospital a week after surgery. Physical preparation, psychological preparation and respiratory preparation are needed before surgery. 1. Physiological preparation: before hospitalization, patients should have a regular work and rest schedule and diet, do not overeat and take large supplements, and female patients should avoid menstruation to enter the hospital for surgery. 2. Psychological preparation: patients may have some emotional changes before the operation, such as apprehension, fear and so on. Therefore, keep a positive mindset, do not be afraid, and have confidence in overcoming the disease. 3. Respiratory preparation: long-term smokers, at least two weeks after quitting smoking before surgery, while deep breathing exercises can be carried out. A small number of patients also need nebulizer treatment after admission to clean the airways to reduce postoperative complications. After surgery for pulmonary nodules, you should rest properly, take appropriate activities, eat more high-quality protein, do not stay up late and overwork, and have regular checkups.
