概括
餐后低血压 (PPH) 可以预测老年手术患者的诱导后低血压 (PIH). 本研究探讨了PPH和PIH之间的联系,以改善老年人手术前护理.
科学领域:
- 麻醉学 麻醉学
- 老年医学 老年医学
- 心血管生理学心血管生理学
背景情况:
- 诱导后低血压 (PIH) 是接受全身麻醉的老年患者常见的并发症,与自主神经系统 (ANS) 功能障碍和不良的术后结果有关.
- 餐后低血压 (PPH),也与ANS功能障碍相关,在老年人群中很普遍.
- 目前用于评估ANS功能的外科手术工具有限,这凸显了对预测标记物的需求.
研究的目的:
- 在接受非心脏手术的老年患者中,探索食后低血压 (PPH) 和诱导后低血压 (PIH) 之间的关系.
- 调查PPH作为PIH在这个脆弱患者群体中的预测因素的潜力.
- 为了提高对老年患者在全身麻醉期间血液动力学不稳定因素的理解.
主要方法:
- 一项前性观察队列研究,涉及120名接受非心脏手术的中国老年患者 (≥65岁).
- PPH通过食后120分钟的血压监测进行评估;PIH从OR入口到麻醉诱导后20分钟进行监测.
- PIH定义为SBP <90 mmHg,MAP <65 mmHg,或在麻醉诱导后20分钟内从基线下降>30%.
主要成果:
- 当研究完成并可获得结果后,该部分应填写.
- 进一步分析将PPH测量与PIH的发病率和严重程度相关联.
- 二次结局包括手术内低血压,术后并发症,30天死亡率和功能状态 (12项WHODAS 2.0).
结论:
- 这项研究旨在确定PPH是否可以作为老年手术患者PIH的预测标志物.
- 这些发现可能会为开发新的策略提供信息,以识别在麻醉期间有血动力学不稳定性风险的患者.
- 改善PIH的预测可以导致有针对性的干预,减少术后并发症和改善老年麻醉的结果.

Alterations in Blood Pressure
1.5K
Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...

Hypertension III: Clinical Manifestations and Diagnostic Studies
60
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

Special considerations while measuring blood pressure
828
When assessing blood pressure (BP), healthcare professionals must consider various factors and potential unexpected outcomes to ensure accurate readings and provide proper patient care. Adhering to these guidelines is essential to achieving the most reliable results.
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.

Hypertension II: Pathophysiology
91
Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...
