概括
被动腿抬起显著改变了儿童的超声波测量结果. 虽然禁食对左心室外流通道Vmax的影响很小,但需要更多的研究来确认其用于检测儿科低血压.
科学领域:
- 儿科重症监护室的儿童重症监护室
- 心血管生理学心血管生理学
- 护理中心超声波检查
背景情况:
- 超声波是一种有价值的非侵入性工具,用于评估音量状态.
- 在儿童中早期发现低血压是及时干预的关键.
研究的目的:
- 评估脱水和被动抬腿对超声波衍生的心脏和下静脉空腔参数的影响.
- 增强儿童患者低血压症的早期检测.
主要方法:
- 一项前性观察性研究在三级儿科重症监护病房进行.
- 66名健康的儿童 (8-14岁) 在禁食前和后进行了超声波测量,有或没有被动抬腿.
- 关键参数包括下腔静脉 (IVC) 的直径和可折叠性,以及左心室外流通道 (LVOT) 速度时间积分和Vmax.
主要成果:
- 被动抬腿导致IVC直径增加和IVC折叠性降低 (p < 0.001).
- 速度时间积分随着被动腿部抬起而增加 (p < 0.001),但没有受到禁食的显著影响 (p = 0.17).
- 在被动抬腿时,LVOT Vmax 增加,在禁食时降低 (p = 0.001).
结论:
- 被动抬起腿部显著影响儿童的超声波测量.
- LVOT Vmax受到禁食诱导的轻度脱水的影响.
- 需要进行进一步的研究,以验证Vmax在预测儿科低血压的有用性.

Assessing Blood pressure using a doppler ultrasound
1.2K
To obtain accurate blood pressure measurements in clinical settings, especially when traditional methods are insufficient, healthcare professionals utilize the Doppler ultrasound technique. This method uses high-frequency sound waves to detect blood flow within the arteries, which is crucial for patients with conditions that complicate circulatory system assessment.

Assessment of the Cardiovascular System III: Palpation
176
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

Imaging Studies for Cardiovascular System III: X-Ray
124
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Cardiovascular System Abnormal Findings II: Auscultation
90
Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

Imaging Studies for Cardiovascular System I:Echocardiography
287
Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...
