目的：探讨宫颈旁神经阻滞及宫颈管粘膜表麻在人流术中松弛宫颈、人流综合征发生及镇痛作用。方法：将３００名孕妇随机分为宫颈旁神经阻滞组；宫颈旁神经阻滞加宫颈管粘膜表麻组（简称联合用药组）及对照组，每组各１００名。比较其上述作用。结果：用药两组宫颈松弛明显、人流综合征发生率低，镇痛效果好，差异有显著性。其中，联合用药组宫颈松弛效果较单用宫颈旁神经阻滞更为明显，Ｐ＜０．０１有显著差异。结论：人流术中应用宫颈旁神经阻滞加宫颈管粘膜表麻可有效降低人流综合征的发生及良好镇痛效果，值得临床应用。
Objective: To investigate the cervical parathyroid nerve block and cervix mucosa epidermal flaccid cervical abortion in the abortion and the occurrence of human flow syndrome and analgesic effect. Methods: 300 pregnant women were randomly divided into cervical parapharyngeal nerve block group; cervical parapharyngeal nerve block plus cervical canal mucosal ephedrine group (referred to as combination therapy group) and control group, each group of 100. Compare the above effects. Results: Two groups of cervical relaxation significantly, the incidence of flow syndrome is low, analgesic effect is good, the difference was significant. Among them, the combination of cervical relaxation effect than single use of paraesthesic nerve block was more obvious, P <0.01 significant difference. Conclusion: The application of paravertebral nerve block plus cervical canal mucosal epidermal anesthesia in abortion can effectively reduce the occurrence of human flow syndrome and good analgesic effect, which is worthy of clinical application.
