Cardiovascular surgery complication and the benefits of pulmonary rehabilitation in preventing COPD exacerbation

Abstract

Introduction. Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality worldwide, and the burden of the disease is constantly increasing. Although COPD is primarily characterized by the presence of airflow obstruction, in many patients, it is associated with systemic manifestations that can result in impaired functional capacity, reduced quality of life, and increased mortality. Pulmonary rehabilitation (PR) consists of a multidisciplinary and comprehensive non-pharmacological intervention that is designed to improve health status in COPD patients, along with pharmacologic treatment. PR has also been shown to improve the diaphragmatic mobility in patients with different conditions that affect the diaphragm. The aim of the paper is to describe the clinical and functional features of a COPD patient with unilateral paralysis of the phrenic nerve and the role of PR as a major component of the case management. Material and method. This paper presents the case of a 66-year-old patient, diagnosed with COPD Gold stage III, which suffered a surgical intervention for an aorta aneurysm and later complicated with phrenic nerve injury and left diaphragmatic paralysis. This condition worsened the respiratory functional status and the patient needed a tailored treatment. Results and discussions. The treatment included besides inhaled dual long acting bronchodilator and corticoid therapy, pulmonary rehabilitation with complex methods, consisting in training of the respiratory musculature and techniques of bronchial drainage using devices with positive inspiratory and expiratory pressure, with good clinical and functional outcomes. A PR program should be included into a personalized management plan, along with pharmacological therapy. Conclusion. Although there is no standard treatment for COPD associated with unilateral paralysis of the phrenic nerve, it is important to diagnose these conditions promptly, and to recommend the adequate pharmacological treatment for controlling the symptoms along with a personalized complex respiratory rehabilitation program, in order to increase functional status and quality of life.
