Effect of Bronchial Artery Protection on Cough After Thoracoscopic Lobectomy

Effect of Preoperative Three-dimensional Reconstruction and Intraoperative Protection of Bronchial Artery on Cough After Thoracoscopic Pneumonectomy

The postoperative complications of thoracoscopic radical surgery for lung cancer mainly include postoperative bleeding, pulmonary infection, chylothorax, nerve injury, pulmonary embolism, arrhythmia, postoperative cough, bronchopleural fistula and so on. Among them, postoperative cough is one of the most common complications after lung surgery, and the incidence of postoperative cough is 25% - 50%. Cough after pneumonectomy can last for a long time, which affects the rapid recovery of patients after surgery, and brings serious adverse effects to the physiological, psychological and social functions of patients.

After pneumonectomy cough on patients' daily life will bring different degrees of adverse effects, so through certain methods to intervene, in order to reduce the incidence of postoperative cough, accelerate the rapid recovery of patients after surgery, improve the quality of life of patients, which should also be worthy of attention of surgeons. In recent years, the research on intervention measures and treatment methods to reduce cough after thoracoscopic lobectomy is mainly focused on drug treatment, traditional Chinese medicine treatment, surgical operation and anesthesia intervention. However, the research on reducing postoperative cough by improving surgical operation is rare. The purpose of this prospective study was to investigate whether preoperative three-dimensional reconstruction and intraoperative protection of bronchial artery can reduce the severity of cough after thoracoscopic lobectomy, so as to further explore the effective intervention measures of postoperative cough and enrich the concept of accelerated rehabilitation surgery.
