Abstract

Chronic obstructive pulmonary disease (COPD) is reported to be not detected in many patients with airflow limitation. Here, we examined the usefulness of preoperative spirometry in identifying patients with latent airflow limitation. The data of 1,496 patients aged 7 to 94 years who had undergone preoperative spirometry, including their history of smoking and past and present illnesses, were collected. When airflow limitation was defined as forced expiratory volume in 1 second/forced vital capacity < 70%, airflow limitation was observed in 222 (14.8%) of all the patients [138 (18.1%) men, and 84 (11.4%) women]. Regarding the relationship between airflow limitation and smoking, the number of patients with airflow limitation was larger among smokers than among nonsmokers, both in men and women. Regarding comorbidities, airflow limitation was observed to be related to heart disease (p = 0.0013) and hypertension (p = 0.0207) in all patients, hypertension (p = 0.0449) in men, and heart disease (p = 0.0019) and osteoporosis (p = 0.0040) in women. Therefore, attention should be paid to not only airflow limitation per se, but also its relationship with comorbidities. Among patients with air flow limitation, those who were diagnosed as having COPD and started receiving treatment for it were only four. Preoperative spirometry may lead to early detection and treatment of COPD patients with latent airflow limitation.
