摘　　要：本文对16例选择性甲状腺手术病例施行颈段硬膜外腔阻滞麻醉,观察其对呼吸功能和血气的影响。结果提示:呼吸功能正常的病人使用低浓度、小容量局麻药作颈段硬外阻滞,如控制局麻药在颈段硬膜外腔的扩散,在不使用辅助药情况下,对呼吸抑制甚微。阻滞前后的血气分析表明,虽然 pH 和PaO_2有差异,但仍在正常范围,无明显低氧血症和呼吸性酸中毒。因此,只要选用适当浓度和容量的局麻药,把阻滞控制在颈脊神经范围内,是安全有效的,可作为颈部手术的一种麻醉方法。Effects of cervical epidural blockade on respiratory function and blood gas were studied in 16 patients undergoing thyroid operation.Results:Although the differences of pH,PaO_2 and PaCO_2 were statistically significant between pre and post cervical epidural blockade,but all indexes kept in physiological ranges during pre and post blockade in patients with normal respiratory function when administering suitable concentration and volume of local anesthetic,hypoxemia and respiratory acidosis didn't appear.Conclusion:The cervivcal epidural blockade is safe and effective when administering suitable concentration and volume of local anesthetic for controlling level of cervical epidural blockade,It can be used in the patients of scheduled neck operation.
