目的:探讨血清β-HCG、P测定结合阴道超声检查对早期输卵管妊娠的诊断价值。方法:选取72例早期输卵管妊娠患者,并随机选取78例同期早期正常宫内妊娠孕妇,测定当日血清β-HCG、P、EST和48 h后的血清β-HCG。结果:研究组血清β-HCG、P水平均明显低于对照组,差异有统计学意义(P<0.01);研究组EST明显小于对照组,差异有统计学意义(P<0.05)。48 h后研究组血清β-HCG值无明显变化,对照组血清β-HCG值明显高于就诊当日约1倍,差异有统计学意义(P<0.01)。结论:单独检测某项指标并不能准确鉴别诊断输卵管妊娠,测定血清β-HCG、孕酮并联合阴道超声检查能有效减少早期输卵管妊娠的漏诊与误诊,值得临床推广。
Objective: To investigate the diagnostic value of serum β-HCG, P combined with vaginal ultrasonography in early tubal pregnancy. Methods: Seventy-two patients with early tubal pregnancy were enrolled. A total of 78 pregnant women with normal intrauterine pregnancy at the same period were randomly selected. Serum β-HCG, P, EST and serum β-HCG were measured at the same day. Results: The serum levels of β-HCG and P in the study group were significantly lower than those in the control group (P <0.01). The EST in the study group was significantly lower than that in the control group (P <0.05). Serum levels of β-HCG had no significant change in the study group after 48 h, while the serum β-HCG level in the control group was significantly higher than that on the day of treatment (P <0.01). Conclusion: The detection of an index alone can not accurately identify the diagnosis of tubal pregnancy, serum β-HCG, progesterone combined with vaginal ultrasound can effectively reduce the missed diagnosis and misdiagnosis of early tubal pregnancy, worthy of clinical promotion.
