To investigate the risk factors for cough after pulmonary resection.
The PubMed, Embase, Web of Science, ClinicalTrials.gov, and China National Knowledge Network databases were searched from inception to November 2022. The Q tests and I statistic were used to evaluate the heterogeneity. Odds ratios (OR) were combined using the inverse variance method. All statistical analyses were performed by RevMan 5.4.1.
Nineteen studies with 4755 patients were included, the incidence of postoperative cough was 21.1%-55.8%. The results showed that young age [OR = 0.66, 95% CI (0.46, 0.96), p = 0.03], female sex [OR = 1.69, 95% CI (1.07, 2.66), p = 0.02], preoperative cough [OR = 5.96, 95% CI (2.58, 13.73), p < 0.01], right lobe operation [OR = 2.14, 95% CI (1.44, 3.19), p < 0.01], lobectomy [OR = 3.70, 95% CI (1.73, 7.90), p < 0.01], subcarinal lymph node dissection [OR = 3.45, 95% CI (1.86, 6.39), p < 0.01], mediastinal lymph node removal [OR = 3.49, 95% CI (2.07, 5.89), p < 0.01], closure of bronchial stump with stapler [OR = 5.19, 95% CI (1.79, 15.07), p < 0.01], peritracheal lymph node resection [OR = 3.05, 95%CI (1.40,6.64), p < 0.01], postoperative acid reflux [OR = 11.07, 95%CI (4.38,28.02), p < 0.01] were independent risk factors for cough after pulmonary resection.
Young age, female sex, preoperative cough, right lobe operation, lobectomy, subcarinal lymph node dissection, mediastinal lymph node removal, closure of bronchial stump with stapler, peritracheal lymph node resection, and postoperative acid reflux are independent risk factors for cough after pulmonary resection.
