概括
在COVID-19患者的肺超声波B线表明感染严重程度和肺高血压,而不是心力衰竭. 这些发现有助于澄清B线超出急性心力衰竭情景的诊断效用.
科学领域:
- 肺部病理学 肺部病理学
- 关键护理医学 关键护理医学
- 诊断成像 诊断成像 诊断成像
背景情况:
- 肺超声波 (LUS) 上的B线表明肺密度增加,这种情况在肺堵塞,肺炎和纤维化等疾病中见到.
- 虽然LUS推用于急性心力衰竭 (HF),但其在非HF人群中的实用性,如COVID-19患者,需要进一步调查.
研究的目的:
- 调查8区LUS B线发现与住院COVID-19患者的临床,实验室和心声数据之间的关联.
- 为了确定LUS B线是否预测非ICU患者队列中的30天死亡率.
主要方法:
- 对确诊COVID-19的住院成年患者进行前性分析.
- 利用趋势和回归分析将8区LUS发现与临床参数,实验室结果 (例如C反应蛋白) 和心声回声数据 (例如LVEF,三回) 相关联.
主要成果:
- 大多数COVID-19患者 (97%) 在LUS.上表现出B线.
- 增加的B线与较高的C-反应蛋白水平和较高的早期预警分数显著相关,表明感染性疾病的严重程度更高.
- 更多的B线与较高的三回梯度有关,这表明肺高血压,但与左侧心脏功能标志物或NT-proBNP无关.
结论:
- 在COVID-19患者中,LUS B线与传染病严重程度和肺高血压的标志物有关.
- 在这种情况下,B线与左侧心力衰竭指标或30天死亡率无关.
- 在心力衰竭中,LUS B线可能会提供超出其既定作用的COVID-19疾病严重程度的宝贵见解.

01:26Factors Affecting the Risk of Infection
13.2K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

01:30Pneumonia I: Introduction
702
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

01:25Transmission-based Precautions II: Airborne and Protective Environment
1.8K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

01:28Pneumonia IV: Management
731
The treatment of pneumonia varies based on its severity and the causative pathogen. Here is a structured approach to managing pneumonia, integrating pharmaceutical and supportive care strategies.
Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:

01:22Healthcare Associated Infections II: Preventive Measures
3.5K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...
