| Abstract | 「abstract」There are few reports of hemodynamic changes during total spinal anesthesia (TSA), although TSA has been used for treatment of a whiplash injury, or for management of general anesthesia. We evaluated the hemodynamics and blood concentrations of catecholamine in two cases managed with TSA. In the first case (the resection of pheochromocytoma), the establishment of TSA did not alter the heart rate (HR), mean blood pressure (mAP) and cardiac output (CO). However, only by the manipulation of the tumor 75 minutes after TSA, these remarkably increased, and after ligation of the adrenal vein returned to the normal level (80 minutes later). In the second case (the resection of non-functional adrenal adenoma), HR, mAP and CO were gradually decreased, and became the lowest 110 minutes after TSA, then returnd to the pre-anesthesia level at the end of the surgery (70 minutes later). Remarkable increases in epinephrine (Ep) and norepinephrine (NE) were observed at and after the time of tumor manipulation in the first case, and a slight increase in NE after tumor manipulation in the second case. We conclude that TSA is stress-free anesthesia and may contribute to anesthesia management in some cases as reported. |
