Carbon Dioxide Retention after Non-Cardiac Surgery in a Patient with Cor Pulmonale

Regional anesthesia is generally recommended over general anesthesia for non-cardiac surgeries in patients with severepulmonary hypertension (PH) caused by pulmonary disease. However, pre-, and intra-, postoperative management are critical for patients with severe PH even when regional anesthesia is performed. This is the first reported case of carbon dioxide retention and administration of the appropriate treatment during non-cardiac surgery performed under spinal/epidural anesthesia and analgesia in a patient diagnosed with chronic cor pulmonale accompanied by severe PH.
