概括

超声导向下大脑下空间深度 (SSD) 测量比传统方法更准确,特别是在肥胖患者中. 这种技术提高了脊柱麻醉的成功率.

科学领域:

麻醉学和重症监护医学
医学成像医学成像
神经外科神经外科

背景情况:

准确的脑下沟空间深度 (SSD) 识别对于成功的脊髓麻醉至关重要.
传统的人类测量方法用于SSD估计具有可变的可靠性,特别是在肥胖患者或脊柱形患者中.
超声波提供实时可视化,但需要对已建立的技术进行验证.

研究的目的:

为了比较超声波引导的SSD估计的准确性和可靠性与人体测量方法.
评估超声波在不同患者群体的有效性,包括那些高BMI.
评估超声波指导在改善脊柱麻醉程序结果方面的潜力.

主要方法:

一项前性观察性研究,涉及56名接受脊柱麻醉的成年患者.
在L3-L4处使用曲线式探针对超声波SSD (USG-SSD) 的术前测量.
使用Bonadio的公式计算人体测量SSD (ANTHRO-SSD),并与实际的手术内SSD测量进行比较.

主要成果:

美国G-SSD (4.5 ± 0.6厘米) 与实际的SSD (4.6 ± 0.5厘米; p=0.12) 非常接近,而ANTHRO-SSD高估了深度 (5.1 ± 0.7厘米; p<0.001).
超声波显示出较高的一致性 (极限: -0.6到+0.4厘米),较低的平均绝对误差 (0.3厘米与0.7厘米相比) 和更强的相关性 (r=0.92与0.75).
精度在超声波的BMI类别中保持一致,与人类测量不同,人类测量在肥胖患者中高估了SSD (误差:1.1 ± 0.5厘米). 超声波在第一次尝试中取得了87.5%的成功.

结论:

超声波引导的SSD估计比人类测量方法更准确和可靠,特别是在高BMI的人群中.
超声指导的整合可能会提高脊柱麻醉的程序成功率.
这种技术可能有助于减少与脊柱麻醉相关的并发症.

Local Anesthetics: Clinical Application as Spinal Anesthesia

Local Anesthetics: Clinical Application as Spinal Anesthesia

Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

Local Anesthetics: Clinical Application as Epidural Anesthesia

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...
