Abstract

Objective: To evaluate the relationship between neonatal biacromial and bideltoid diameter (BDD), birth weight and shoulder dystocia (SD).

Material and methods: This was a prospective observational study conducted on 161 pregnancies who applied to Private Lokman Hekim Hospital for follow-up between February 2021 and August 2021. Maternal height, weight, parity, and presence of SD in the second stage of labor were evaluated in the patients included in the study. The weight, height, head circumference, biacromial and BDD measurements of newborn babies were taken within the first two hours after birth. The primary purpose of the study was to evaluate the relationship between the biacromial and BDD and SD. The secondary purpose of the study was to evaluate the relationship between the biacromial and BDD and macrosomia.

Results: The mean age and post-pregnancy body mass index of the participants were 31.3±4.4 years and 29.0±4.0 kg/m2, respectively, and 42.9% (n=69) delivered vaginally. The incidence of macrosomia was 6.8% (n=11) in all women and the incidence of SD was 7.2% (n=5) in women who had vaginal deliveries. The mean biacromial diameter (BAD) was 12.4±1.0 cm and the mean BDD was 18.2±1.7 cm. A correlation rate of 0.373 was found between SD and the BAD, and 0.484 between SD and the BDD. The correlation coefficients between macrosomia and the biacromial and BDD were 0.213 and 0.420, respectively. In cases in which the BDD was ≥21 cm, the sensitivity for SD was 100%, the specificity was 90.63%, and the accuracy was 91.30%. The cut-off point for the BAD was ≥14 cm, and the sensitivity and specificity for SD was 63.64% and 89.33%, respectively. The highest correlation for SD was obtained in cases in which there was a history of SD (0.648).

Conclusion: The relationship between neonatal biacromial and BDD, and macrosomia and SD were significant. There was no difference between the correlation values of the two measurements in terms of SD. However, the correlation coefficient of the BDD was greater for macrosomia.

双峰距和双峰距对新生儿肩难产和出生体重的影响

目的:探讨新生儿双峰和双峰样直径(BDD)、出生体重与肩难产(SD)的关系。材料和方法:这是一项前瞻性观察研究，对2021年2月至2021年8月期间向私立Lokman Hekim医院申请随访的161名孕妇进行了研究。对纳入研究的患者的产妇身高、体重、胎次和分娩第二阶段是否存在SD进行评估。新生儿在出生后2小时内测量体重、身高、头围、双肩峰和BDD。本研究的主要目的是评估双峰与BDD和SD之间的关系。该研究的第二个目的是评估双峰症和BDD与巨大儿之间的关系。结果:参与者的平均年龄为31.3±4.4岁，孕后体重指数为29.0±4.0 kg/m2，经阴道分娩的占42.9% (n=69)。所有妇女中巨大儿的发生率为6.8% (n=11)，阴道分娩妇女中SD的发生率为7.2% (n=5)。平均双峰直径(BAD) 12.4±1.0 cm，平均双峰直径(BDD) 18.2±1.7 cm。SD与BAD的相关率为0.373,SD与BDD的相关率为0.484。巨大儿与双峰和BDD的相关系数分别为0.213和0.420。在BDD≥21 cm的病例中，SD的敏感性为100%，特异性为90.63%，准确性为91.30%。BAD的分界点≥14 cm, SD的敏感性和特异性分别为63.64%和89.33%。在有SD病史的病例中，SD相关性最高(0.648)。结论:新生儿双肩畸形与BDD、巨大儿与SD的关系显著。两次测量的相关值在SD方面没有差异。然而，巨大儿的BDD相关系数更大。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
