宫颈封闭联合笑气吸入治疗宫颈水肿的临床疗效研究

Clinical study of cervix blockade combined with nitrous oxide in the treatment of cervical edema

目的研究宫颈封闭联合笑气吸入治疗宫颈水肿的临床效果。方法将我院2012年9月~2013年9月收治的200例宫颈水肿产妇作为研究对象,随机分为观察组和对照组,每组各100例,比较两组的治疗效果。结果与对照组相比,观察组宫颈口开始扩张时间快、宫颈口扩张持续时间长、宫口直径大、产程时间较短且产后出血量少,两组上述指标比较差异显著（P=0.000）;两组患者治疗后疼痛、宫颈水肿症状均有明显改善,观察组改善程度优于对照组（P=0.000）;观察组顺产率明显高于对照组,差异有统计学意义（P=0.000）;观察组宫颈裂伤率少于对照组,且差异具有统计学意义（P=0.003）;两组新生儿窒息比率均较低,差异无统计学意义。结论宫颈封闭联合笑气吸入能有效治疗宫颈水肿,缩短产程时间,增加宫颈口扩张持续时间,减少患者的疼痛感、出血量,且宫颈裂伤、新生儿窒息比率低。

Objective To investigate clinical effect of cervix blockade combined with nitrous oxide in the treatment of cervical edema. Methods Clinical and follow-up data of 200 patients with cervical edema between September 2012 and September 2013 in our hospital were randomly divided into the observation group （100 eases） and the control group （100 cases）.The clinical treatment effect of the two groups was assessed. Results The time of cervical expansion in the observation group were earlier than those in the control group, the duration time of cervical expansion in the observa- tion group were longer than those in the control group ,the bottleneck diameter in the observation group were longer than those in the control group, the labor time in the observation group were shorter than those in the control group, the amount of postpartum hemorrhage in the observation group were less than those in the control group, and the difference was significant （P〈0.01）.The symptoms of pain and cervical edema were improved statistically after treatment,and the improvement in the observation were better than those in the control group （P〈0.01）;The eutocia rate in the observation was higher than that in the control group ,and there was statistically significant difference （P〈0.01）.The rate of cervical laceration in the observation was lower than that in the control group, there was statistically significant difference （P〈 0.01 ）. The rate of neonatal asphyxia had no significant difference between the observation and the control group. Con- clusion Cervix blockade combined with nitrous oxide could cure effectively forcervical edema,shorten labor time,pro- long the duration time of cervical expansion, relieve pain ,and reduce the amount of bleedlng.The rate of cervical lac- eration and neonatal asphyxia is low.
