人流吸宫术时,由于牵拉、扩张宫颈和负压吸引对宫壁的刺激等,受术者往往感到腰酸、下腹胀痛等,少数出现面色苍白、心动过缓、出冷汗等人流综合征。为了减轻受术者痛苦,防止人流综合征,曾有人试用针灸、耳针、利多卡因宫颈旁神经阻滞等方法,但有的效果不显,或操作繁复,不适宜于门诊人流手术大批量进行。我院根据全麻插管前用利多卡因喷雾喉部使之松弛的启发,在人流或放环扩张宫颈前用利多卡因作颈管内口涂抹麻醉,取得较好效果。 Abortion flow Palace, due to traction, expansion of the cervix and vacuum to attract the stimulation of the uterine wall, etc., by those who often feel backache, abdominal pain, a few appear pale, bradycardia, cold syndrome such as cold sweat . In order to reduce the suffering of the surgeon, to prevent the flow of people syndrome, there have been trials of acupuncture, ear acupuncture, lidocaine paraventricular nerve block and other methods, but some of the effect is not significant, or complicated operation, not suitable for outpatient abortion get on. In our hospital, under anesthesia, lidocaine was sprayed on the larynx for relaxation before anesthesia intubation. Anesthesia was given to the inner mouth of the cervical canal with lidocaine before the abortion or ring expansion, and good results were obtained.
