Using a standardized technique, spinal anesthesia was induced in 50 term parturients to study the correlation between patient height, weight, and body mass index (BMI) and the spread of sensory blockade. All patients received 12 mg hyperbaric bupivacaine while in the right lateral decubitus position on a horizontal operating table. Immediately after drug injection, the women were turned to the supine horizontal position with left uterine displacement. Fifteen minutes after drug injection, the level of analgesia to pinprick was measured. Linear regression analysis revealed no significant correlation between height (146-175 cm), weight (57.3-93.6 kg), or body mass index (21-38 kg/m2) and the spread of spinal anesthesia (T7-C8). It is concluded that, in term parturients, patient height, weight, or BMI does not significantly affect the spread of hyperbaric spinal anesthesia.
采用标准化技术，对50名足月产妇实施脊髓麻醉，以研究患者身高、体重和体重指数（BMI）与感觉阻滞范围之间的相关性。所有患者在水平手术台上取右侧卧位时接受12mg高压布比卡因。注射药物后，立即将产妇转为仰卧位并向左移位子宫。注射药物15分钟后，测量针刺镇痛水平。线性回归分析显示，身高（146 - 175cm）、体重（57.3 - 93.6kg）或体重指数（21 - 38kg/m²）与脊髓麻醉范围（T7 - C8）之间无显著相关性。结论是，在足月产妇中，患者身高、体重或BMI对高压脊髓麻醉的范围无显著影响。
