There are usually several cases of coughing after gallstone surgery. One is laparoscopic gallbladder surgery, which is usually performed under general anesthesia, and general anesthesia involves tracheal intubation. Although the patient does not feel any pain after the surgery, because he is under general anesthesia, there is no pain at all, but there is irritation to the pharynx after tracheal intubation. Therefore, the patient’s pharynx is irritated after the surgery and he has a reactive cough. In addition, we leave a gastric tube in the patient during surgery so as not to interfere with the surgical field. However, in such a patient, the gastric tube also irritates the pharynx to a certain extent, so the patient will have a short-term cough after surgery. Two, the patient can easily get through with cough medicine, I think it is not worth considering.
