概括
胃食道逆流发生在近一半的患者在10分钟内麻醉诱导,主要是由于短暂的下胃食道关节放松 (TLESR). 这种反流不涉及屏障压力下降,并留在食道中.
科学领域:
- 麻醉学 麻醉学
- 胃肠病学 胃肠病学
- 医疗器械 医疗器械
背景情况:
- 上部胃肠道运动障碍在麻醉诱导期间很常见,增加了反流吸收的风险.
- 有限的研究存在于胃食道逆流的发生率和特征,特别是在麻醉诱导期间.
- 高分辨率阻抗测量 (HRIM) 提供了一种新的方法来研究在这个关键时期的食道功能.
研究的目的:
- 使用HRIM描述麻醉诱导期间胃食道逆流的发生和性质.
- 为了研究麻醉剂 (普罗波与顺胆相比) 和反流事件之间的关系.
- 为了确定反流的潜在机制,特别是短暂的下食道关节放松 (TLESR) 和屏障压力 (BrP) 的变化.
主要方法:
- 总共研究了28名接受麻醉诱导的患者.
- 患者被分为两组:14组接受了普罗波和顺胆,14组接受了普罗波和罗库.
- 在整个麻醉诱导过程中,通过HRIM导管连续收集食道阻抗和压力数据.
主要成果:
- 在麻醉引发之前,没有患者经历过反流.
- 在诱导10分钟内,42.9% (12/28) 的患者经历了胃食道逆流.
- 所有的反流事件 (共16例) 都留在食道中;反流与TLESR有关,而不是降低屏障压力,麻醉组之间没有显著差异.
结论:
- 胃食道逆流是麻醉诱导期间经常发生的事件,在10分钟内观察到高达42.9%的患者.
- 主要的机制是短暂的食道下关节放松 (TLESR),独立于胃食道屏障压力下降.
- 该研究强调了HRIM在麻醉期间特征反流的实用性,并建议TLESR作为一个关键因素.

Gastroesophageal Reflux Disease I: Meaning and Pathophysiology
1.3K
Gastroesophageal Reflux Disease (GERD) involves the recurrent backflow of the stomach or duodenal contents into the esophagus, leading to troublesome symptoms and potential esophageal mucosal damage. Although GERD is often referred to as a disease, it is more accurately described as a syndrome, as it encompasses a range of symptoms and complications rather than a singular pathological entity, impacting a large number of individuals as the most prevalent upper gastrointestinal problem. Roughly...

Endoscopic Procedures I: Esophagogastroduodenoscopy
935
An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Stages of General Anesthesia
1.5K
Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

Esophageal Strictures-I: Introduction
651
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

Upper GI Series: Barium Swallow
1.5K
The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.
Purpose and Procedure
Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...
