利多卡因宫颈注射与宫旁阻滞在人流术中镇痛的随机对照研究

目的：比较利多卡因宫颈注射与宫旁阻滞在人流术中镇痛的效果.材料和方法：对我院2005年1～2月门诊终止妊娠的早孕妇女64例,随机分为两组：宫颈注射组34例和宫旁阻滞组30例.比较两种利多卡因局麻方式的效果.结果：宫旁阻滞麻醉的止痛效果优于宫颈注射（P=0.026）;宫旁阻滞对宫颈的松弛作用优于宫颈注射（P=0.04）;副作用均较轻微,两组间比较无显著差异.结论：利多卡因宫旁阻滞在人流术中的镇痛效果优于宫颈注射,且经济、安全,适于在基层医院和贫穷地区推广.

A Random Contrast Study: the Influence of Cervical Injection or Paracervical Block with Lidocaine on Pain Relief during Suction Evacuation for Early Pregnancy Termination

Objective:To compare the influence of cervical injection (CI) or paracervical block(PCB) with lidocaine on pain relief during suction evacuation for early pregnancy termination.Method:We collected 64 cases of early pregnancy women who want to have suction evacuation for pregnancy termination.From January to February in 2005 in the outpatient department in our hospital.They were assigned randomly to the group of cervical injection (34 cases) and the group of paracervical block(30 cases).The outcome of these two lidocaine local anaesthesia was compared.Results:PCB is better than CI for the pain relief(P=0026) and cervical relaxation(P=004).There were no significant differences of adverse effects between the two groups.Conclusion:PCB with lidocaine is better than CI on pain relief during suction evacuation for early pregnancy termination,it's economical and safe and proper to be extended in poor region or basic medical unit.
