概括
手术前禁食指南的目的是减少胃的含量. 然而,这项研究发现,患者的饥渴感与实际的胃液量有很弱的相关性,这表明腹感不是手术患者胃空化的可靠指标.
科学领域:
- 麻醉学 麻醉学
- 胃肠病学 胃肠病学
- 外科手术患者管理
背景情况:
- 术前禁食对于手术安全至关重要,以尽量减少胃内含物.
- 胃超声可以揭示显著的液体体积或固体含量,尽管禁食.
- 患者报告的腹感 (饥饿和口渴) 已被提出作为胃空化的补充措施.
研究的目的:
- 为了研究主观饥饿评级与空腹手术患者客观的胃液总体体积之间的相关性.
- 评估口渴与胃液体体积之间的关系.
- 为了检查饥饿,口渴和Perlas胃含量分级尺度之间的关联.
主要方法:
- 一项前性观察性研究,涉及515名接受手术前禁食的选择性手术患者.
- 用胃超声学测量胃液体体积.
- 饥饿和口渴使用0-10数值评分表量化; 珀拉斯分级也被评估.
主要成果:
- 在胃液量和饥饿之间观察到非常微弱的正相关性 (斯皮尔曼的rho=0.11,P=0.01).
- 同样,胃液量和口渴之间也发现了微弱的正相关性 (斯皮尔曼的rho=0.11,P=0.02).
- 胃液体体积与Perlas分级尺度对饥饿或口渴之间没有显著的相关性.
结论:
- 通过饥饿和口渴来衡量主观腹感,在空腹的手术患者中,与胃液总体体积的相关性非常弱.
- 腹感并不是胃液量或胃空化的可靠预测指标.
- 当前的禁食指导方针和客观的措施,如胃超声波,对于在手术前评估胃的含量至关重要.

Gastric Emptying
969
Gastric emptying occurs when the stomach gradually releases chyme into the duodenum. When the stomach is distended, it triggers the release of gastrin, a hormone that promotes gastric acid secretion to aid in digestion. Additionally, stomach distension contributes to peristaltic waves that propel gastric contents toward the pyloric region. The gastroenteric reflex, on the other hand, primarily stimulates peristalsis in the intestines, facilitating the movement of contents further along the...

Assessment of the Gastrointestinal System I: Subjective Data
233
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health History
The initial step in assessing the GI system is obtaining a comprehensive health history. This includes inquiring about the patient's history or presence of problems...

Regulation of Food Intake
289
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Gastric Phase of Digestion
1.2K
The gastric phase of digestion begins as soon as food enters the stomach. The incoming food bolus triggers neural and hormonal mechanisms, which last approximately 3 to 4 hours. During this phase, the stomach undergoes significant changes to prepare the food for further digestion and absorption.
When food enters the stomach, it stretches the stomach walls and activates stretch receptors. This triggers local reflexes of the enteric nervous system, mediated through the myenteric plexus. These...

Gastric Motility
852
Gastric motility is the coordinated contraction and relaxation of stomach muscles that convert ingested food into chyme, a semi-liquid substance ready for further digestion in the intestines. The process begins with the vagus nerve inducing the relaxation of the smooth muscles in the fundus and body of the stomach, allowing these regions to expand and accommodate up to approximately 1.5 liters of food and liquid.
