AbstractBecause a standard type of graduated compression stocking is not effective for the prevention of spinal anesthesia hypothension during cesarean section, we have used an extra-strong type of graduated compression stocking. This study examined whether the extra-strong stocking reduces usage of vasopressor agents. Forty-eight and 47 full term parturients were fitted with the standard stocking and the extra-strong stocking, respectively. Spinal anesthesia was performed by injecting 2.0 ml 0.3% dibucaine hyperbaric solution. When systolic blood pressure decreased to 90-100 mmHg or to less than 70% of the pre-anesthesia value, ephedrine was injected. There was no significant difference in systolic blood pressure or heart rate during spinal anesthesia between the groups. The mean dose of ephedrine injected during anesthesia was 12.2 and 4.3 mg, and the incidence of ephedrine injected was 85 and 49%, in the standard and extra-strong stocking groups, respectively. The extra-strong stocking group showed significantly lower values. Fitting the extra-strong stocking on both legs for cesarean sections undergoing spinal anesthesia reduced usage of vasopressor agents, suggesting a promising use of this stocking for non-invasive prophylaxis.
