Outline of Final Research Achievements

The positive effects of early ambulation in postoperative patients have been demonstrated. However, we often experience unexpected hypotension due to tachycardia or bradycardia, or symptoms such as dizziness in those patients. Therefore, we decided that needed to assess the effects of autonomic nerve activity during ambulation in patients who underwent general anesthesia.
We assessed circulation dynamics and autonomic nervous activity in those patients based on progressive ambulation preoperative and on postoperative days 1 and 3. Although we did not find any significant changes in circulation dynamics, parasympathetic activity decreased significantly with the postural change from the supine to the standing position on postoperative day 1, with sedation dose found to be an index prescribing the rate of change. We also found that sympathetic activity on the same day increased significantly, and that water balance in surgery was the index prescribing the rate of change for this.
