Clinically speaking, 3-5 days of stool after minimally invasive lung surgery are normal. Minimally invasive lung surgery is highly recognized by doctors and patients because of its many features such as short operation time, small incision, fewer complications, quicker postoperative recovery, and good protection of lung function, and it is now mainly used for lung nodule resection treatment. However, since lung surgery is performed under general anesthesia, gastrointestinal motility will be weakened after anesthesia, and lying in bed after surgery will also weaken gastrointestinal motility, and some patients suffer from constipation due to the accumulation of gas in the intestinal tract, too little food and gastrointestinal dysfunction. Therefore, general patients should follow the doctor’s instructions to get out of bed as soon as possible to promote intestinal excretion, but also to drink more water in moderation, eat more fresh fruits and vegetables, daily clockwise massage of the abdomen in order to promote gastrointestinal peristalsis, as a way to prevent and improve the constipation problem. If necessary, you can use Keflex under the guidance of a doctor to help defecation.
