[Left lung lavage affected the cardiac autonomic nervous activity more than right lung lavage during one lung ventilation in a patient with pulmonary alveolar proteinosis].
A 31-year-old man with pulmonary alveolar proteinosis underwent whole lung lavage using differential lung ventilation under general anesthesia with propofol and fentanyl. Left lung lavage was performed under the differential lung ventilation using extracorporeal lung assist. A month later, right lung lavage was performed under the differential lung ventilation alone. We compared left lung lavage with right one in the effects on heart rate variability and relationships between heart rate and arterial pressure. In the left lung lavage compared with the right one, arterial pressure was maintained higher; sympathetic nervous activity was kept tonic as shown in the power spectral analysis of heart rate variability; coherency showed lower; and a phase relationship analysis indicated a delay of almost 180 degrees. Therefore, we conclude that left lung lavage affected the cardiac autonomic nervous activity more than right one in differential lung ventilation.
