概括
与预定的剖腹产相比,非计划性剖腹产 (CDs) 与复合性孕产妇出血结局 (CMHOs) 的比率明显更高. 这些风险包括增加出血,输血和手术干预,强调了分娩规划的重要性.
科学领域:
- 产科和妇科 产科和妇科
- 孕产妇健康 孕产妇健康
- 外科手术的结果
背景情况:
- 剖腹产 (CD) 是一种常见的产科手术.
- 孕产妇出血仍然是发病率和死亡率的重要原因.
- 了解出血并发症的风险因素对于改善孕产妇安全至关重要.
研究的目的:
- 为了比较预定和非预定剖腹产 (CDs) 之间的复合孕产妇出血结局 (CMHOs),单期分娩.
- 评估先前的子宫外科手术对不同CD时间组中CMHO的影响.
主要方法:
- 对经过CD的单期分娩的回顾性队列研究.
- CMHOs被定义为严重出血指标的复合物 (例如,失血≥1,000毫升,输血,手术).
- 多变量波松回归用于计算调整后的相对风险 (aRR) 和95%置信区间 (CI).
主要成果:
- 与预定CD相比 (16.9%;aRR=2.18),非预定CD (36.5%) 的CMHO率 (34.5%) 显著更高.

01:29Local Anesthetics: Clinical Application as Epidural Anesthesia
414
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
