概括
诱导分娩 (IoL) 方法的有效性各不相同. 虽然一些方法 (如氧化捐赠者) 可能会减少子宫过度刺激,但在没有先前剖腹产的女性中,没有一种方法在其他关键结果方面明显优于阴道mizoprostol.
科学领域:
- 产科和妇科 产科和妇科
- 生殖医学 生殖医学
- 临床试验 研究 研究 临床试验 临床试验
背景情况:
- 当怀孕的风险超过好处时,就会采用催产 (IoL),目前有10多种方法可供使用.
- 最优和最安全的 IoL 方法仍然不清楚,需要进行比较分析.
研究的目的:
- 为了比较各种宫成熟和IOL方法的益处和危害.
- 排列这些在产期或超期开始劳动的方法.
主要方法:
- 一个系统性审查和网络元分析 (NMA) 的106个随机对照试验 (RCTs) 涉及30348名妇女.
- 包括的方法是国际指导方针或之前的科克莱恩审查建议的方法.
- 分析对先前剖腹产和没有剖腹产的女性进行了分层分析,重点关注分娩失败和剖腹产率等关键结果.
主要成果:
- 对于以前没有剖腹产的女性,没有一种 IoL 方法在减少由于胎儿状态不令人放心而无法实现阴道分娩或剖腹产时,明显优于阴道mizoprostol (≤ 50 μg).
- 氧化捐赠者,透性宫扩张器,气球导管和口服美索普罗斯托尔 (≤50μg) 可能会减少与阴道美索普罗斯托尔相比,胎儿心率变化的子宫过度刺激.
- 对于以前进行过剖腹产的女性,证据有限.
结论:
- 对于以前没有剖腹产的女性,阴道弥索普罗斯托尔 (≤50μg) 作为基准,没有任何方法显示出关键分娩结果的显著优势.
- 某些方法,包括氧化捐赠器和透性宫扩张器,在子宫过度刺激方面似乎更安全.
- 需要进一步的研究来澄清最佳的IOL策略,特别是对于以前剖腹产的妇女来说.

4.5K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

01:09Directing Effect of Substituents: meta-Directing Groups
5.9K
Substituents on the benzene ring that direct an incoming electrophile to undergo substitution at the meta position are called meta directors. All meta directors either have a positive charge on the atom directly bonded to the ring or a partial positive charge. These groups function by withdrawing electrons from the ring through inductive and resonance effects. Consider the carbocation intermediates formed upon the addition of an electrophile on nitrobenzene at the...

02:18Network Covalent Solids
16.1K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

01:16Induction
5.7K
An emf is induced when the magnetic field in a coil is changed by pushing a bar magnet into or out of the coil. emfs of opposite signs are produced by motion in opposite directions, and the directions of emfs are also reversed by reversing poles. The same results are produced if the coil is moved rather than the magnet—it is the relative motion that is important. The faster the motion, the greater the emf. Additionally, there is no emf when the magnet is stationary relative to the coil.

01:24Self-Inductance
3.1K
Mutual inductance arises when a current in one circuit produces a changing magnetic field that induces an emf in another circuit. On the other hand, self-inductance arises when the current passing through the circuit changes, creating a changing magnetic flux, resulting in inductance in the same circuit.
Consider a circuit connected to an AC source. As the current varies with time, the magnetic flux through the circuit correspondingly changes. Faraday's law tells us that an emf would...
