概括

母亲发病率和胎盘增长谱 (PAS) 率随着每次剖腹产而增加. 胎盘位置,特别是胎盘前部,显著增加PAS风险,强调需要谨慎管理.

科学领域:

产科和妇科产科和妇科
孕产妇和胎儿医学孕产妇和胎儿医学
手术结果研究研究.

背景情况:

在全球范围内,剖腹产率稳步增加.
以前的剖腹产是已知的胎盘增殖谱 (PAS) 的风险因素.
了解与剖腹产史和胎盘位置相关的当代发病率对于患者护理至关重要.

研究的目的:

为了确定当前的孕产妇死亡率和PAS.
分析之前剖腹产产史对这些率的影响.
调查胎盘位置对PAS风险的影响.

主要方法:

对44,608例剖腹产 (2011年1月 - 2024年5月) 的回顾性队列研究.
根据之前的剖腹产产次数,对母亲人口统计,病率 (PAS,子宫切除,输血) 和手术时间进行比较.
对胎盘位置 (胎盘前,低躺的胎盘) 的分析及其与PAS和子宫切除风险的关联.

主要成果:

孕产妇发病率,包括PAS (0.03%至2.8%) 和子宫切除 (0.5%至4.2%),随着剖腹产数量 (P <.001) 的增加而显著增加.
前置胎盘和低躺的胎盘显示出明显增加的PAS率,特别是在多次先前剖腹产.
剖腹产史增加和胎盘前部位于子宫下部的位置与PAS和子宫切除术的几率比率显著增加有关.

结论:

随着相继的剖腹产,孕产妇的发病率上升,这是由于异常胎盘和粘合性疾病的增加所致.
胎盘位置,特别是前胎盘或低躺的胎盘,是PAS风险的关键决定因素.
这些发现强调了在评估和管理PAS风险时考虑剖腹产史和胎盘位置的重要性.

Disorders of the Female Reproductive System

Disorders of the Female Reproductive System

The female reproductive system can be affected by several disorders, including Premenstrual Syndrome (PMS), Premenstrual Dysphoric Disorder (PMDD), endometriosis, and various forms of cancer. PMS and PMDD are cyclical conditions that cause physical and emotional distress, with symptoms that include edema, mood swings, and food cravings. PMDD is a more severe form of PMS characterized by increased symptom severity that peaks during the luteal phase and tends to improve or resolve shortly after...

Teratogenicity

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
