概括

怀孕24周后的晚期乳液化是诊断遗传疾病的安全和有效方法,特别是在具有多种异常的胎儿中. 这一程序为明智的决策和围产期护理规划提供了关键信息.

科学领域:

医学遗传学医学遗传学
产前诊断在产前诊断
产科产科产科产科产科

背景情况:

乳液化通常在怀孕15-22周之间进行遗传诊断.
有限的数据存在于24周妊娠后进行的乳液灌注的安全性和准确性.

研究的目的:

为了评估在妊娠24周或之后进行的乳液灌注的指示,诊断产量,安全性和结果.

主要方法:

一项国际多中心回顾性队列研究包括752名接受晚期乳液化 (怀孕24-36周) 的孕妇.
分析的数据包括指示,进行的基因测试,诊断产量和孕产妇/胎儿结局.
并发症和分娩结果在术后2周内进行评估.

主要成果:

晚期羊膜切割主要用于结构异常 (91.6%),诊断收益率为22.9%.
多个器官系统异常 (36.4%) 与单个 (15.3%) 的诊断产量更高.
并发症率很低 (1.2%),早产率没有显著差异.

结论:

晚期乳液化 (≥24周) 是临床上有用的,提供高的诊断产量和低的并发症率.
它对于具有先天性异常的怀孕特别有价值,能够提供知情的咨询和护理计划.
该程序在分娩前提供及时的遗传信息,以优化新生儿护理.

Endoscopic Studies II: Thoracocentesis

Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
