Summary
Brief summary (as posted)
Lung cancer, as the main cause of cancer-related deaths in both males and females, is a great risk to human health. Pulmonary resection is the most applicable to early-stage lung cancer diagnoses and considered the best curative options. Coughing is a prominent symptom among postoperative complications, with approximately 18%-50% of patients experiencing persistent coughing after surgery. This study is a prospective observational study and is expected to be carried out in a large tertiary hospital. This cohort is expected to include 1000 participants for three years. Patients with pulmonary nodules on chest CT will be divided into two groups based on the presence or absence of cough symptoms on admission. The investigators decided whether to include patients in this cohort study strictly based on the inclusion and exclusion criteria. The severity of cough, the trajectory of cough change, and the physiological and social burden caused by cough will be reflected by the results of LCQ-MC, CSS, HARQ, and VAS. LCQ-MC, CSS, HARQ, and VAS are just a few of the questionnaires that are widely used to investigate the cough and severity of the respondent. The included variables included age, gender, Height, Weight, education level, smoking history, alcohol history, preoperative lung function, nodule size, preoperative and postoperative blood routine (such as white blood cell count, neutrophil count, etc.), blood biochemistry (such as C-reactive protein, PCT, etc.), liver and kidney function test results, surgical method, surgical site, operation duration, anesthesia method, anesthesia duration, lymph node dissection, pathological results, chest tube caliber, number of days of catheterization, use of cough drugs, use of non-steroidal anti-inflammatory drugs, Number of days in hospital and number of outpatient visits due to cough.
