Abstract

The aim of the study is to assess the frequency of pregnancy complications and the mode of delivery in COVID-19 women performing delivery in the district clinical hospital in the city of Khanty-Mansiysk. Materials and Methods. The authors retrospectively analyzed 148 medical histories of COVID-19 women, who delivered in Khanty-Mansiysk perinatal center. All patient medical records were divided into 4 subgroups depending on the delivery term, and 3 subgroups depending on the disease severity. Statistical analysis was carried out using analytics software packages Statistica 10 (USA) and StatTech v. 2.8.4 (Stattech, Russia, 2020). Given group heterogeneity, non-parametric statistical methods were used to calculate quantitative and qualitative parameters. Fisher Z transformation and the Mann-Whitney test were used to compare the parameters. Differences were considered statistically significant at p≤0.05, CI 95 %. Results. In all subgroups the most common pregnancy complication in COVID-19 patients was anemia. It was observed in 50.8 % to 74.3 % of cases. The maximum incidence of moderate preeclampsia was 2.7 %, that is below the average population value. Most placental abnormalities were detected in subgroups of women who gave birth during 3rd and 4th waves of COVID-19 (37.1 % and 33.8 % respectively). In the same subgroups, fetal growth retardation (28.6 % and 32.3 %), statistically significant increase in the proportion of preterm births (34.3 % and 38.5 %) and transfers to the neonatal intensive care unit (28.6 % and 26.2 %) were often observed.
汉特曼西斯克地区临床医院分娩的COVID-19妇女的妊娠并发症和分娩方式
该研究的目的是评估在汉特-曼西斯克市地区临床医院分娩的COVID-19妇女妊娠并发症的频率和分娩方式。材料与方法。作者回顾性分析了在汉特-曼西斯克围产期中心分娩的148名COVID-19妇女的病史。所有患者病历根据分娩时间分为4个亚组,根据疾病严重程度分为3个亚组。使用统计软件包Statistica 10(美国)和StatTech v. 2.8.4 (StatTech,俄罗斯,2020)进行统计分析。考虑到群体异质性,采用非参数统计方法计算定量和定性参数。采用Fisher Z变换和Mann-Whitney检验对参数进行比较。p≤0.05认为差异有统计学意义,CI 95%。结果。在所有亚组中,COVID-19患者最常见的妊娠并发症是贫血。50.8% ~ 74.3%。中度先兆子痫的最高发生率为2.7%,低于平均人群值。在第三波和第四波分娩的妇女亚组中检测到大多数胎盘异常(分别为37.1%和33.8%)。在同一亚组中,经常观察到胎儿发育迟缓(28.6%和32.3%),早产(34.3%和38.5%)和转至新生儿重症监护病房(28.6%和26.2%)的比例有统计学意义上的显著增加。
