【摘要】：目的探討臍動(dòng)脈(UA)聯(lián)合大腦中動(dòng)脈(MCA)檢測(cè)胎兒宮內(nèi)缺氧的價(jià)值。方法將2015年2月至2016年2月該院分娩的孕婦349例按照是否存在胎兒宮內(nèi)缺氧分為觀察組(胎兒宮內(nèi)缺氧組)和對(duì)照組(胎兒無宮內(nèi)缺氧組)。將兩組的UA、MCA收縮期最高流速與舒張末期流速比(S/D)、搏動(dòng)指數(shù)(PI)、阻力指數(shù)(RI)、(S/D)MCA/(S/D)UA、PIMCA/PIUA、RIMCA/RIUA進(jìn)行比較,統(tǒng)計(jì)各指標(biāo)診斷胎兒宮內(nèi)缺氧的敏感度、特異度、Youden指數(shù)。結(jié)果孕28~35+6周及孕36~41周觀察組UA S/D、PI、RI值高于對(duì)照組(P0.05),而MCAS/D、PI、RI值及(S/D)MCA/(S/D)UA、PIMCA/PIUA、RIMCA/RIUA值低于對(duì)照組(P0.01)。MCA、UA的阻力指標(biāo)相應(yīng)比值診斷胎兒缺氧的Youden指數(shù)最高。結(jié)論聯(lián)合使用胎兒UA和MCA阻力指標(biāo)比值來預(yù)測(cè)胎兒宮內(nèi)缺氧的臨床價(jià)值更高。
[Abstract]:Objective to investigate the value of umbilical artery occlusion (UAA) combined with middle cerebral artery (MCA) in detecting fetal intrauterine hypoxia. Methods 349 pregnant women born in the hospital from February 2015 to February 2016 were divided into observation group (fetal intrauterine hypoxia group) and control group (fetus without intrauterine hypoxia group) according to the existence of fetal intrauterine hypoxia. The ratio of peak systolic velocity to end-diastolic velocity was compared between the two groups, and the sensitivity, specificity and Youden index of fetal intrauterine anoxia were determined by comparing the ratio of peak systolic velocity to end-diastolic velocity (S / D), pulsatility index (Pi), resistance index (R / D) and MCAR / R / D ratio of PIMCA / Pi UAA to RIMCARIUA. Results the RI value of UA S- DV Pi in observation group was higher than that in control group (P 0.05), but the value of MCAS / DV Pi I I RI and S / D MCA P / D MCA P / D MCA P / D MCA / Pi IUA were lower than those of control group (P 0.01). The Youden index of fetal anoxia was the highest in the control group (P 0.01U 路MCAU / R = 0. 01%), but it was higher than that in the control group (P < 0. 01), but there was no significant difference between the two groups in diagnosis of fetal hypoxia. Conclusion the combined use of the ratio of fetal UA and MCA resistance index to predict fetal intrauterine hypoxia is of higher clinical value.
