概括
在脊髓麻醉 (SA) 后,强迫呼吸量在一秒内显著减少 (FEV1) 与手术内缺氧的增加有关. 这一发现突出了FEV1作为SA期间不良心肺事件的潜在预测因子.
科学领域:
- 麻醉学 麻醉学
- 肺部病理学 肺部病理学
- 心脏病学 心脏病学
背景情况:
- 脊柱麻醉 (SA) 广泛用于下部手术,但可能导致手术内并发症.
- 现有的SA相关心肺问题解释,如同情阻塞和Bezold-Jarisch反射是不完整的.
- 一秒内强制呼吸量减少 (FEV1) 被认为是突然心脏死亡的预测因素.
研究的目的:
- 调查SA后FEV1降低与手术内心肺部不良并发症发生之间的关联.
- 为了确定FEV1在SA后是否发生变化,可以预测特定的不良事件,如缺氧,低血压,心肌梗塞和恶心/吐.
主要方法:
- 一项前性研究,涉及48名患者 (ASA I-II) 在SA.下接受选择性手术.
- 在SA诱导前和30分钟后进行螺旋测量,以测量预测的FEV1%.
- 根据预测FEV1%降低≥10%,对患者进行分类;逻辑回归分析了与不良事件的关联,并对共变量进行调整.
主要成果:
- 预测平均FEV1%在SA后显著下降 (95.31%在SA前与83.42%在SA后,p=0.001).
- 预测FEV1%的≥10%降低与手术内缺氧风险增加显著相关 (AOR 13.55,p=0.044).
- 在≥10%的FEV1降低和低血压,心肌梗塞或恶心/吐之间没有发现统计学上显著的关联.
结论:
- 在SA后预测的FEV1%的降低与不良的手术内结果有关,特别是缺氧.

Local Anesthetics: Clinical Application as Spinal Anesthesia
587
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...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy
53
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Local Anesthetics: Clinical Application as Epidural Anesthesia
417
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...

Endoscopic Studies II: Thoracocentesis
208
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...

General Anesthesia: Overview
196
Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

Skeletal Muscle Relaxants: Therapeutic Uses
470
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx...
