Abstract

Pneumonia in elderly people is mainly caused by silent aspiration due to an age-related impairment of cough and swallowing reflexes. Because most of the patients with lung cancer are elderly people, we hypothesized that the age-related impairment of these protective reflexes might exist or occur in patients undergoing lung surgery, and cause postoperative pneumonia. We revealed that many elderly patients showed depressed swallowing reflex even before surgery and transient attenuation of cough reflex after surgery, and that postoperative pneumonia occurred only in the patients whose cough and/or swallowing reflex was abnormal postoperatively. Then, we prospectively showed that 30 elderly patients who received perioperative intensive oral care, including professional assessment of oral status, dental cleaning, and patient education for self-oral care by dentists, followed by intensive oral care by intensive care unit nurses, and encouragement of self-oral care by floor nurses, did not develop pneumonia after lung resection. In this study, we retrospectively reviewed the execution status of professional oral care by dentists and the occurrence of postoperative pneumonia in 159 consecutive patients aged 65 or older undergoing lung resection from 2013 to 2014. Thoracic surgeons in our institute asked dentists to provide professional oral care before lung resection only in 30.3% of the subjects in 2013, and 45.8% in 2014. Postoperative pneumonia occurred in 3 out of 76 subjects(3.9%)in 2013, and 1 out of 83(1.2%) in 2014. In 2013, 1 patient who did not receive preoperative professional oral care developed aspiration pneumonia postoperatively followed by acute exacerbation of idiopathic pulmonary fibrosis and in-hospital death. We need to make an effective system to provide preoperative professional oral care by dentists especially for elderly patients and high-risk patients before lung resection.
