Delayed Respiratory Distress in a Patient With Chronic Obstructive Pulmonary Disease After Abdominal Surgery

摘要

Patients with chronic obstructive pulmonary disease (COPD) are at increased risk for perioperative complications. The frequency of complications depends on the severity of COPD, the type of anesthesia used, the surgical site, and other comorbidities. Patients undergoing upper abdominal surgery have significant changes in lung volumes, likely secondary to changes in diaphragm function and abdominal pain, and these changes increase the risk for complications, including acute respiratory failure, atelectasis, pneumonia and unplanned reintubation. We discuss a patient with COPD who did well for the first 3 days following an open incisional hernia repair. However, on the fourth day he noted significant dyspnea and radiographic studies revealed atelectasis. Over the next week the patient remained symptomatic and dependent on noninvasive ventilation; he eventually had a rapid response to corticosteroids. This case indicates that atelectasis can develop late following a surgical procedure and that multiple factors potentially influence development of this complication.
