In pregnancy, hematological changes occur in order to meet the demands of the developing fetus and placenta, with major alterations in blood volume. Abnormal hematological profile affects pregnancy and its outcome. This study aimed to assess hematological profiles of pregnant women at a tertiary care teaching hospital.
This cross sectional study was conducted among 284 consecutive pregnant women at St. Paul's Hospital Millennium Medical College. Socio-demographic characteristics were collected using pre-tested structured questionnaire. About 4 ml of venous blood was collected from each participant for hematological parameters analysis using Cell-Dyn1800 (Abbott Laboratories Diagnostics Division, USA) and peripheral blood film review.
There were differences in mean hematological parameters between trimesters: specifically differences in mean values of WBC (1and 3rd), Hb(1stand2 and 1& 3rd), HCT (1and2nd), RDW (1and2 and 1and3rd), neutrophil and lymphocyte (1stand 2nd and 1and3 for both) were statistically significant ( < 0.05). The prevalence rates of anemia and thrombocytopenia were 11.62 and 7.7%, respectively and were dominantly of mild type. On the bases of blood picture, we classified anemia's of pregnancy as microcytic hypochromic (51.5%), normocytic hypochromic (27.3%), normocytic normochromic (18.2%), and dimorphic (3%).
Significant changes in selected hematological parameters between trimesters, and an anemia and thrombocytopenia of mild type were documented in this study. The commonest morphologic features were mostly characteristic features of iron deficiency anemia. These warrant the need for monitoring hematological parameters of pregnant women at any stage of the pregnancy to avoid adverse outcomes.
在孕期,为满足发育中的胎儿和胎盘的需求,血液学发生变化,血容量有重大改变。异常的血液学指标会影响妊娠及其结局。本研究旨在评估一家三级护理教学医院中孕妇的血液学指标。
本横断面研究在圣保罗医院千禧医学院对284例连续的孕妇进行。使用预先测试的结构化问卷收集社会人口学特征。从每位参与者采集约4毫升静脉血,使用Cell-Dyn1800(美国雅培实验室诊断部)分析血液学参数并进行外周血涂片检查。
孕期各阶段的平均血液学参数存在差异:具体而言,白细胞(第1和第3阶段)、血红蛋白(第1和第2阶段以及第1和第3阶段)、血细胞比容(第1和第2阶段)、红细胞分布宽度(第1和第2阶段以及第1和第3阶段)、中性粒细胞和淋巴细胞(两者的第1和第2阶段以及第1和第3阶段)的平均值差异具有统计学意义(<0.05)。贫血和血小板减少症的患病率分别为11.62%和7.7%,且主要为轻度类型。根据血象,我们将妊娠贫血分为小细胞低色素性贫血(占比51.5%)、正细胞低色素性贫血(占比27.3%)、正细胞正色素性贫血(占比18.2%)和双相性贫血(占比3%)。
本研究记录了孕期各阶段选定血液学参数的显著变化,以及轻度贫血和血小板减少症。最常见的形态学特征大多是缺铁性贫血的特征。这些情况表明有必要在孕期的任何阶段监测孕妇的血液学参数以避免不良结局。
