概括
产科关节损伤 (OASI) 风险在超过26000个分娩中被研究. 胚胎切除没有被发现是OASI的危险因素,但仪器分娩增加了风险,特别是在第一次母亲中.
科学领域:
- 产科和妇科 产科和妇科
- 围产期健康 围产期健康
- 手术并发症 手术并发症
背景情况:
- 产妇关节损伤 (OASI) 是阴道分娩的严重并发症,与显著的孕产妇发病率有关.
- 已确定的危险因素包括初级亲属,晚年母亲年龄,仪器分娩,催产素使用和宏观性.
- 乳房切除术最近被提议作为OASI的潜在新风险因素.
研究的目的:
- 为了调查羊水切割和产科关节损伤 (OASI) 在单独的阴道分娩之间的关联.
- 评估羊膜切割作为OASI独立风险因素的作用,考虑已知的决定因素.
- 分析34周妊娠后分娩中OASI的危险因素.
主要方法:
- 使用来自Innlandet Perinatal数据库 (2012-2022) 的数据进行了回顾性队列研究.
- 纳入标准:怀孕34周后单独的阴道分娩.
- 采用多变量逻辑回归模型来确定风险因素,包括胚胎切除和已确定的决定因素,并对平价进行分层.
主要成果:
- 在包括的26,349个出生中,OASI的发病率保持稳定,每年约为2%.

Assessment of the Rectum and Anus
1.0K
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

Local Anesthetics: Clinical Application as Epidural Anesthesia
661
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...

Appendicitis-I: Introduction
2.0K
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
