概括
手持式超声波 (HHU) 和基于车的超声波系统 (CBUS) 在急诊室的超声波导向IV导管 (USGIV) 放置中同样有效. 这项研究发现,这两种系统的成功率或过早失败率没有显著差异.
科学领域:
- 紧急医疗 紧急医疗
- 医疗器械 医疗器械
- 护理中心超声波检查
背景情况:
- 超声导入式输液导管 (USGIV) 放置在急诊室 (ED) 是常见的.
- 传统的基于车的超声波系统 (CBUS) 是有效的,但繁且往往有很高的需求.
- 手持式超声波 (HHUs) 提供了一个便携式替代方案,但与CBUS相比,它们在USGIV安置中的有效性尚未得到证实.
研究的目的:
- 为了比较HHUs与CBUS在ED环境中的USGIV安置的成功率.
- 为了确定HHU是否在此过程中不劣于CBUS.
- 评估对使用HHU的ED提供者进行额外培训的需要.
主要方法:
- 一项前性,随机的非劣势性研究与312名需要USGIV的成年ED患者进行.
- 患者被随机分配到经过培训的ED医生或护士使用CBUS或HHU进行USGIV安置.
- 成功被定义为即时用盐水冲洗;收集了尝试,特征和持续时间的数据.
主要成果:
- 在HHU (145/312) 和CBUS (146/312) 组之间,总体USGIV安置成功率没有显著差异 (p≥0.9).
- 在成功的USGIV安置方面,HHU被证明与CBUS无差 (p=0.0001).
- 第一次尝试成功率和过早USGIV失败率在HHU和CBUS组之间是相似的.
结论:
- 手持式超声波与基于车的超声波系统相比,对于成功地将USGIV安置在ED.
- 在HHU和CBUS之间的首次尝试成功或设备存活率方面没有发现显著差异.
- ED提供者不需要任何重要的额外培训来有效地使用HHU用于USGIV程序.

Cardiac Catheterization II: Right Heart Catheterization
Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
Cardiac Catheterization III: Left Heart Catheterization
Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...
Cardiac Catheterization IV: Nursing Management
Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...
