【摘要】：通過對心音信號的收集、測量，分析高齡孕婦心臟儲備功能的變化，，對高齡孕婦的心臟功能做出客觀、量化的評估；從妊娠合并癥、并發(fā)癥、分娩方式及圍生兒結(jié)局幾個方面對比分析高齡孕婦與非高齡孕婦間的差異，比較不同妊娠合并癥及分娩方式對孕產(chǎn)婦心臟儲備功能的影響，強調(diào)孕婦心臟儲備功能的重要性，降低高齡孕婦妊娠合并癥、并發(fā)癥及不良妊娠結(jié)局發(fā)生率，以利于高齡孕婦安全度過妊娠和分娩，提高圍產(chǎn)期保健質(zhì)量。 目的 評估高齡孕婦的心臟儲備功能，降低高齡孕婦妊娠合并癥、并發(fā)癥及不良妊娠結(jié)局的發(fā)生率，提高圍產(chǎn)保健質(zhì)量。 材料與方法 1研究對象 本論文選取2012年9月至2013年9月期間在鄭州大學第三附屬醫(yī)院門診做圍產(chǎn)保健的分娩年齡≥35歲的127例孕婦作為高齡組,同期的孕周相同或相近的分娩年齡＜35歲的127例孕婦作為對照組，相關(guān)信息采用統(tǒng)一調(diào)查問卷。 2研究方法 應用博精醫(yī)學信息研究所研制的“運動心力檢測儀”收集研究對象的相關(guān)信息資料及心音信號，測量、計算和分析心臟舒張期時限(Diastolic phaseduration，D)比收縮期時限(Systolic phase duration，S)(D／S)的變化趨勢，探討高齡孕婦心臟儲備功能的變化，對比分析不同妊娠合并癥及分娩方式對孕產(chǎn)婦心臟儲備功能的影響。 3統(tǒng)計學處理 采用SPSS17.0進行數(shù)據(jù)的統(tǒng)計分析，各指標以(x s)表示，對于兩組樣本均數(shù)間的比較采用t檢驗；對于多組樣本均數(shù)間的比較采用單因素方差分析；對于率的比較采用χ2檢驗，以α=0.05為檢驗水準。 結(jié)果 1不同年齡組孕婦的D/S值：≤24歲組D/S值為(1.50±0.09)，25～29歲組D/S值為(1.47±0.17)，30～34歲組D/S值為(1.44±0.13)，35～39組D/S值為(1.36±0.11)，≥40歲D/S值為(1.18±0.11)，結(jié)果顯示5個年齡組D/S值比較有統(tǒng)計學差異(F=6.850，P=0.000)，其中≤24歲組和25～29歲組D/S比較無統(tǒng)計學差異（P=0.068），其他各年齡組之間差異均有統(tǒng)計學意義（P0.05）。 2不同孕周D/S值的比較：在28～36+6周及≥37周，高齡組與非高齡組間D/S值的差異有統(tǒng)計學意義（P0.05），≤27+6周時，兩組間D/S值無顯著性差異（P＞0.05）。 3妊娠合并癥及并發(fā)癥孕婦D/S值比較：合并妊娠期高血壓、貧血孕婦的D/S值低于未出現(xiàn)該合并癥的孕婦，差異有統(tǒng)計學意義（P0.05）。 4不同分娩方式孕婦D/S值的比較：剖宮產(chǎn)孕婦的D/S值低于經(jīng)陰道分娩的孕婦，差異有統(tǒng)計學意義（P0.05)。 5妊娠結(jié)局：高齡孕婦中早產(chǎn)兒的發(fā)生率高于非高齡孕婦，差異有統(tǒng)計學意義（P0.05)。 結(jié)論 高齡孕婦的心臟儲備功能低于正常育齡期孕婦；高齡孕婦心臟儲備功能的無創(chuàng)檢測方法值得在臨床推廣應用,可以早期預測孕婦心臟功能的異常。
[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 偽 -0. 05. Results. 1 the D / S value of pregnant women of different age groups: the D / S value of pregnant women 鈮
