概括
正式的护理点超声波 (POCUS) 培训提高了居民的信心和图像解释得分. 然而,信心和使用频率与知识没有相关性,这表明直接的知识评估是评估POCUS课程的关键.
科学领域:
- 医学教育 医学教育
- 在护理地点进行超声波 (POCUS)
- 内部医疗住院内科医生
背景情况:
- 护理点超声波 (POCUS) 是一种有价值的病床诊断工具,特别是在移动的军事环境中.
- 缺乏正式,统一的POCUS培训和依赖基于信任的评估带来了挑战.
- 评估POCUS课程的有效性需要了解信心,利用和知识之间的关系.
研究的目的:
- 评估一个正式的POCUS课程对内科医生实习生的影响.
- 评估居民信心,POCUS使用频率和图像解释知识之间的相关性.
- 确定评估POCUS培训计划的最有效方法.
主要方法:
- 一项前后前性队列研究评估了2020年11月实施的纵向,反转教室的POCUS课程.
- 居民的信心是用利克尔特比例表来衡量的,使用频率是用五分级来评估的.
- 用视频评估的六个多选题来评估图像解释能力,得分以百分比正确为准.
主要成果:
- 平均图像解释分数从课前41%提高到课后51% (P=0.02).
- 与课程前相比,居民信心在课程后显著增加 (平均值=3.62),而在课程前 (平均值=2.56).
- 无论是信心还是使用频率都没有显示出与课程后图像解释分数的显著关联.
结论:
- 虽然POCUS课程提高了居民的信心和知识,但信心和利用本身并不是图像解释技能的可靠指标.
- 通过多选择题等方法直接评估知识对于评估POCUS培训的有效性至关重要.
- 未来的POCUS课程应该优先考虑客观的知识评估,而不是主观的信任测量.

4.5K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

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...
