Abstract:

Objective To investigate the risk factors for arrhythmia after pulmonary resections. Methods The incidences of postoperative complications of 399 patients undergoing pulmonary resections were retrospectively analysed, and univariate and multivariate regression analysis was conducted on risk factors for arrhythmia after operation. Results Thirty-two patients (8.02%) experienced arrhythmia after operation. Univariate analysis revealed that the risk factors included age (≥60 years old), complication with cardiopathy other than coronary heart disease, operative approaches (more than single lobectomy), and non-tumor conditions (P<0.05 or P<0.01). Multivariate analysis demonstrated that the independent risk factors included age (≥60 years old) and operative approaches (more than single lobectomy) (P<0.01, P<0.05). Conclusion For patients with risk factors undergoing pulmonary resections, it is important to avoid unnecessary injury during operation, and perform diagnosis and treatment as early as possible. The management of primary respiratory diseases also plays a role in reducing tissue hypoxia.
