【摘要】：通过对心音信号的收集、测量，分析高龄孕妇心脏储备功能的变化，，对高龄孕妇的心脏功能做出客观、量化的评估；从妊娠合并症、并发症、分娩方式及围生儿结局几个方面对比分析高龄孕妇与非高龄孕妇间的差异，比较不同妊娠合并症及分娩方式对孕产妇心脏储备功能的影响，强调孕妇心脏储备功能的重要性，降低高龄孕妇妊娠合并症、并发症及不良妊娠结局发生率，以利于高龄孕妇安全度过妊娠和分娩，提高围产期保健质量。 目的 评估高龄孕妇的心脏储备功能，降低高龄孕妇妊娠合并症、并发症及不良妊娠结局的发生率，提高围产保健质量。 材料与方法 1研究对象 本论文选取2012年9月至2013年9月期间在郑州大学第三附属医院门诊做围产保健的分娩年龄≥35岁的127例孕妇作为高龄组,同期的孕周相同或相近的分娩年龄＜35岁的127例孕妇作为对照组，相关信息采用统一调查问卷。 2研究方法 应用博精医学信息研究所研制的“运动心力检测仪”收集研究对象的相关信息资料及心音信号，测量、计算和分析心脏舒张期时限(Diastolic phaseduration，D)比收缩期时限(Systolic phase duration，S)(D／S)的变化趋势，探讨高龄孕妇心脏储备功能的变化，对比分析不同妊娠合并症及分娩方式对孕产妇心脏储备功能的影响。 3统计学处理 采用SPSS17.0进行数据的统计分析，各指标以(x s)表示，对于两组样本均数间的比较采用t检验；对于多组样本均数间的比较采用单因素方差分析；对于率的比较采用χ2检验，以α=0.05为检验水准。 结果 1不同年龄组孕妇的D/S值：≤24岁组D/S值为(1.50±0.09)，25～29岁组D/S值为(1.47±0.17)，30～34岁组D/S值为(1.44±0.13)，35～39组D/S值为(1.36±0.11)，≥40岁D/S值为(1.18±0.11)，结果显示5个年龄组D/S值比较有统计学差异(F=6.850，P=0.000)，其中≤24岁组和25～29岁组D/S比较无统计学差异（P=0.068），其他各年龄组之间差异均有统计学意义（P0.05）。 2不同孕周D/S值的比较：在28～36+6周及≥37周，高龄组与非高龄组间D/S值的差异有统计学意义（P0.05），≤27+6周时，两组间D/S值无显著性差异（P＞0.05）。 3妊娠合并症及并发症孕妇D/S值比较：合并妊娠期高血压、贫血孕妇的D/S值低于未出现该合并症的孕妇，差异有统计学意义（P0.05）。 4不同分娩方式孕妇D/S值的比较：剖宫产孕妇的D/S值低于经阴道分娩的孕妇，差异有统计学意义（P0.05)。 5妊娠结局：高龄孕妇中早产儿的发生率高于非高龄孕妇，差异有统计学意义（P0.05)。 结论 高龄孕妇的心脏储备功能低于正常育龄期孕妇；高龄孕妇心脏储备功能的无创检测方法值得在临床推广应用,可以早期预测孕妇心脏功能的异常。
[Abstract]:Through the collection and measurement of cardiac sound signals, the changes of cardiac reserve function of elderly pregnant women were analyzed, and the cardiac function of elderly pregnant women was evaluated objectively and quantitatively. The differences between older and younger pregnant women were analyzed from the aspects of delivery mode and perinatal outcome. The effects of different complications of pregnancy and delivery mode on the cardiac reserve function of pregnant women were compared, and the importance of cardiac reserve function of pregnant women was emphasized. To reduce the incidence of complications and adverse pregnancy outcomes in elderly pregnant women, so as to facilitate the safe passage of pregnancy and delivery, and improve the quality of perinatal care. Purpose. To evaluate the cardiac reserve function of elderly pregnant women, to reduce the incidence of complications and adverse pregnancy outcomes, and to improve the quality of perinatal care. Materials and methods. 1 object of study. During the period from September 2012 to September 2013, 127 pregnant women aged more than 35 years were selected as the senior age group in the outpatient clinic of the third affiliated Hospital of Zhengzhou University. 127 pregnant women with the same or similar gestational age < 35 years were used as control group. The relevant information was investigated by uniform questionnaire. 2 research methods. In this paper, using the "exercise cardiac force tester" developed by the Institute of Medical Information of Bojing, to collect relevant information and heart sound signals of the study subjects, to measure, calculate and analyze the change trend of cardiac diastolic diastolic duration (DX) than systolic systolic cardiac stress (S / D), and to measure, calculate and analyze the change trend of cardiac diastolic duration (diastolic systolic rhythm), and analyze the change trend of cardiac diastolic duration compared with systolic diastolic duration (SD). To investigate the changes of cardiac reserve function in elderly pregnant women, and to compare and analyze the effects of different complications of pregnancy and delivery mode on cardiac reserve function of pregnant women. 3Statistical processing. The statistical analysis of the data was carried out by SPSS17.0, and the indexes were expressed in the form of X s. T test was used to compare the mean values of the two groups of samples, a single factor analysis of variance was used to compare the mean numbers of multiple groups of samples, and 蠂 2 test was used to compare the rates. The test level was 伪 -0. 05. Results. 1 the D / S value of pregnant women of different age groups: the D / S value of pregnant women 鈮
