目的分析椎管内分娩镇痛方式对于孕产妇子宫收缩持续时间以及间隔时间造成的影响。方法选取医院分娩的孕产妇120例随机分为观察组和对照组,每组60例。观察组采用硬膜外镇痛分娩处理,对照组未进行分娩镇痛。分析2组孕产妇子宫收缩持续时间以及宫缩间隔时间。结果观察组孕产妇进行分娩镇痛后10~30min子宫收缩时间相对于镇痛前均明显缩短(P<0.01),镇痛后1 h子宫收缩持续时间与镇痛前比较差异无统计学意义(P>0.05)。对照组孕产妇镇痛后30 min、1 h宫缩间隔时间与镇痛前比较差异均无统计学意义(P>0.05),观察组镇痛后孕产妇30 min、1 h宫缩间隔时间4~5 min占比高于镇痛前(P<0.05)。结论孕产妇实施硬膜外镇痛分娩可达到良好的镇痛效果,镇痛后30 min内会在一定程度上抑制子宫收缩,镇痛1 h内也可能会在一定程度上影响宫缩间隔时间,正确认识椎管内分娩镇痛对孕产妇子宫收缩的影响,有利于提高分娩镇痛成功率。
Objective To analyze the effect of intra-spinal analgesia on the duration and interval of uterine contractions in pregnant women. Methods A total of 120 pregnant women were randomly divided into observation group and control group with 60 cases in each group. The observation group was treated with epidural analgesia and childbirth, while the control group was not given labor analgesia. Analysis of two groups of pregnant women uterine contraction duration and contractions time. Results In the observation group, the uterine contraction time from 10 to 30 minutes after labor analgesia was significantly shorter than that before the analgesia (P <0.01), and the duration of uterine contractions at 1 hour after analgesia was not significantly different from that before the analgesia (P < P> 0.05). The control group at 30 min after maternal analgesia, contractions at 1 h and before analgesia was no significant difference (P> 0.05), the observation group after maternal 30 min, 1 h contractions interval 4 ~ 5 min higher than before analgesia (P <0.05). Conclusion Maternal epidural analgesia delivery can achieve good analgesic effect within 30 min after analgesia will inhibit the uterine contraction to a certain extent, analgesia within 1 h may also affect the degree of contractions to a certain extent Correct understanding of spinal canal analgesia on maternal uterine contraction, is conducive to improving the success rate of labor analgesia.
