概括

预测大脑动脉静脉形 (AVM) 显微手术期间的主要血液损失至关重要. 五个因素预测出大量出血,这会影响患者的治疗结果,而一种新的静血方法显示出有前途.

科学领域:

神经外科神经外科
血管外科血管外科
医疗器械医疗器械

背景情况:

术内流血是大脑动脉静脉形 (AVM) 微手术中的一个重大挑战.
有限的研究存在于预测和管理在这些程序期间的主要血液损失.

研究的目的:

为了确定预测大脑AVM微手术中的手术内大血损失的因素.
为了研究重大失血对患者结局的影响.
为了评估一种新的静血方法,骨 (BW) 涂层双极电凝.

主要方法:

对131名接受大脑AVM微手术的患者进行了回顾性分析.
严重失血的定义是≥1,000毫升.
多变量逻辑回归用于识别主要血液损失的预测因素.
评估BW涂层双极电凝疗效和安全性.

主要成果:

确定了五种主要血液损失的独立预测因素:临床表现,巢穴位置和大小,深静脉排水和排水静脉的数量.
严重的失血会对手术进展产生不利影响,并预测手术前期的结果不佳.
用BW涂层的双极电凝疗法证明了高效的血液静止和减少血管损伤.

结论:

在大脑AVM微手术中开发了一种预测性输血图,用于手术内严重的血液损失.
在外科手术期间发生的重大血液损失与患者不良后果有关.
双极电凝是控制AVM手术中严重出血的潜在方法,需要进一步研究.

Aneurysm IV: Nursing Management

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
