支配子宫的神经有交感神经,副交感神经及其伴随的传导神经纤维,而宫颈管处神经分布更为丰富,在人流术中对宫颈扩张、牵拉及宫壁的负压吸引,易引起迷走神经兴奋,而出现一系列的人工流产综合征,早在1921年 Gellent 首先提出用神经阻滞的办法,阻断宫颈及宫体神经的向心传导,减轻受术者的痛苦,多年来许多学者通过各种方法试图减少人工流产中受术者的痛苦。盐酸布比卡因为一较新的长效麻药,具有感觉阻滞时间长,镇痛效果好的优点。我国于1982年才普遍应用于临床,但用于子宫粘膜表面麻醉,国内尚未见报道。本文以盐酸布比卡因作子宫粘膜麻醉无痛人工流产手术的尝试,结果达到满意的效果。现总结如下:
Dominate the uterus of the nerves are sympathetic, parasympathetic and its accompanying conductive nerve fibers, and the cervix at the nerve distribution more abundant in abortion in the abortion of the cervix, stretch and Palace of the negative pressure to attract easily lead to vagal nerve excitement , A series of abortion syndromes appeared. As early as 1921, Gellent first proposed nerve block method to block the conduction of the cervical and uterine nerves to the heart and alleviate the sufferings of the affected persons. For many years, many scholars adopted The approach seeks to reduce the suffering of those affected by abortion. Bupivacaine HCl, a relatively new long-acting anesthetic, has the advantage of long-term blockade and good analgesia. China was generally used in clinical practice in 1982, but for the uterine mucosal surface anesthesia, has not been reported in China. In this paper, bupivacaine hydrochloride for uterine mucosa painless artificial abortion surgery attempt to achieve satisfactory results. Now summarized as follows:
