概括
一个新的充满水的患者物品袋 (PBB) 显示了使用超声波检测软组织中的异物体 (FB) 的潜力. 这种方法,加上水浴和凝,可能比液袋更好地用于FB识别.
科学领域:
- 紧急医疗 紧急医疗
- 医疗成像医学成像
- 超声波技术 超声波技术 超声波技术
背景情况:
- 护理点超声波 (POCUS) 对于识别软组织外体 (FBs) 是有价值的.
- 像阻隔和水浴这样的成像接口可以提高表面结构的超声波分辨率.
- 最佳的接口选择对于准确的FB检测至关重要.
研究的目的:
- 确定用于检测软组织中的异物体的最佳超声波成像接口.
- 为了比较不同接口的精度和图像质量,假设水浴是优越的.
主要方法:
- 对四种超声波成像接口的前性分析:凝,盐水袋对峙,水浴,以及一个新的充满水的患者物品袋 (PBB).
- 在培训中的18名急诊医生在猪模型中对标准化异物 (木材,塑料,金属) 进行了成像.
- 主要结果:FB检测的准确性;次要结果:检测时间,图像质量和培训水平的影响.
主要成果:
- 对 PBB 观察到最准确的趋势,其次是水浴,凝和盐溶液袋.
- 凝超声波的准确性明显高于盐水袋 (P=0.0120).
- 培训水平的提高与检测时间的减少 (P=0.02) 和准确度的提高相关,研究员的表现优于居民和实习生.
结论:
- 充满水的患者物品袋 (PBB) 为软组织外体检测提供了一个可行的替代接口.
- 应考虑PBB,水浴和凝接口,而不是盐水对峙,以改善异物体识别.

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...
