B超检测妊娠晚期子宫下段瘢痕厚度对再次剖宫产的意义

目的探讨B超检测妊娠晚期子宫下段瘢痕厚度对再次剖宫产的价值。方法将94例再次剖宫产孕产妇按照子宫下段瘢痕厚度分为〈3 mm组和≥3 mm组各47例,比较2组术中出血量、产后出血例数和缩宫素使用量,以评价B超检测瘢痕厚度对再次剖宫产的价值。结果 〈3mm组术中出血量为（336.9±118.4）mL,产后出血例数有9例（19.15%）,缩宫素使用量为（90.1±18.7）U,均明显高于≥3 mm组（P〈0.01）。结论通过B超检测子宫瘢痕厚度可以有效地指导再次剖宫产,具有重要的临床意义。

B-test in late pregnancy on the thickness of the lower uterine segment cesarean section scar significance

Objective To investigate the B-test trimester uterine segment cesarean section scar vicious value again. Methods In accordance with scar thickness is 3mm,94 cases of cesarean section will be divided into maternal3mm group and ≥ 3mm each group 47 cases. Comparison of two blood loss,the number of cases of postpartum hemorrhage and oxytocin usage to re-evaluation of the value of B-test cesarean scar thickness. Results 3mm group blood loss was 336.9 ± 118.4mL,the number of cases of postpartum hemorrhage in 9 cases（19.15%）,oxytocin usage was 90.1±18.7 U,significantly higher than the index ≥ 3mm group（P〈0.05）. Conclusion B-test scar thickness can effectively guide cesarean section has important clinical significance.
