- 临床护理 儿科 临床护理 儿科
- 临床诊断 临床诊断 临床诊断
背景情况:
- 早期识别儿童的休克对于及时干预和改善结果至关重要.
- 在儿科紧急情况中,用于冲击诊断的现有临床征兆具有可变的准确性.
- 临床症状的预测值可能在脆弱的儿科群体中不同,例如营养不良或严重贫血患者.
研究的目的:
- 评估各种儿童休克临床指标的诊断准确性和预测能力.
- 为了比较不同临床症状在识别需要立即医疗干预的儿科患者中的有效性.
- 为了研究这些症状在同时存在营养不良或严重贫血的儿童中的表现.
主要方法:
- 一项前性研究招募了2579名儿童 (2个月至17岁),这些儿童患有急性疾病,被送往儿科急诊室.
- 儿童被分为冲击 (需要在1小时内使用液体/血管活性剂) 和非冲击组.
- 评估了临床症状的诊断准确性,分析按营养不良和严重贫血状态分层. 用分类和回归树 (CART) 分析来开发一个预测模型.
主要成果:
- 微弱脉冲对冲击检测表现出最高的灵敏度和特异性 (>85%),诊断几率比为38.8.8.
- 慢心跳和毛细血管补充时间 (CRT) >2秒显示灵敏度和特异性超过70%.
- 低血压和昏迷是营养不良和严重贫血儿童中最重要的冲击预测因素. 一个CART模型确定了三种冲击场景,涉及弱脉冲,短呼吸,低血压和凉爽的外围的组合.
结论:

01:24Blood Pressure Imbalances and Circulatory Shock
1.5K
Disorders affecting blood volume, vascular tone, or vascular function can disrupt vascular homeostasis, including conditions like hypertension, hemorrhage, and shock.
Blood Pressure: Hypertension and Hypotension
Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...

783
Inspection is the initial step in assessing the cardiovascular system. It involves a detailed visual examination that provides crucial information about a patient's circulatory and cardiac health. This systematic process, conducted from head to toe, helps identify signs of cardiovascular conditions by observing physical appearance, skin and mucous membranes, jugular and carotid pulsations, chest symmetry, and the condition of the extremities.

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...
