概括
与通常使用的0.3毫克剂量相比,用于过敏反应的肌肉内氨酸 (0.5毫克) 的较高初始剂量显著降低了需要升级护理的需要. 这一发现支持优化上腺素剂量,以更好地管理过敏反应.
科学领域:
- 过敏和免疫学 过敏和免疫学
- 紧急医疗 紧急医疗
- 药理学 药理学是指药理学的学科.
背景情况:
- 过敏反应是一种严重的,危及生命的过敏反应,需要及时治疗.
- 肌肉内注射 (IM) 上腺素是对过敏反应的标准一线治疗方法.
- 目前的剂量实践,通常使用0.3毫克,对于50公斤以上的成年人来说可能是不理想的,可能导致风险增加.
研究的目的:
- 为了评估在初始肌内上对过敏反应进行注射后护理升级的发生率.
- 为了比较患者接受0.3毫克与0.5毫克IM上腺素之间的结果.
主要方法:
- 对因过敏反应而接受0.3毫克或0.5毫克IM上腺素治疗的患者的回顾性分析.
- 主要结局:升级护理的发生率 (额外的IM上腺素,上腺素输注或输管).
- 二次结果:用剂组之间的不良影响比较.
主要成果:
- 与0.5毫克组 (n=84,7.1%,p <0.001) 相比,0.3毫克组 (n=254) 的护理升级率 (29.5%) 显著更高.
- 在0.3毫克组中,需要额外的IM剂量和上腺素输注的必要性更频繁.
- 多变量分析证实,0.5毫克每日上腺素独立与较低的升级护理率有关.
结论:
- 与0.3毫克相比,初始给予0.5毫克IM上腺素用于过敏反应与显着较低的护理升级需求有关.
- 这些发现表明,0.5毫克每日上腺素可能是某些成年人群的更有效的初始剂量.
- 建议进行进一步的前性研究,以验证这些结果并为临床指南提供信息.

Insulin: Dosing Regimen and Adverse Effects
677
Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

Adrenergic Agonists: Therapeutic Uses
1.6K
Adrenergic agonists have diverse therapeutic uses across various medical conditions and emergencies.
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

Drug Accumulation During Multiple Dosing: Repetitive IV Injections
249
Calculating drug dosage and accumulation in multiple-dose regimens is crucial for achieving therapeutic efficacy while avoiding toxicity. This involves determining the plasma drug concentrations over time to optimize dosing schedules. The principle of superposition is fundamental in this process, allowing for the prediction of drug concentration in plasma following multiple doses based on single-dose data.The principle of superposition asserts that the plasma concentration-time curves from...

Adrenergic Agonists: Mixed-Action Agents
1.4K
Mixed-action adrenergic agonists, like ephedrine and pseudoephedrine, directly and indirectly affect adrenergic receptors. These agents stimulate adrenoceptors and indirectly release stored neurotransmitters, amplifying the adrenergic response.
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...

Pharmaceutical Alternatives: Stability-Related Therapeutic Nonequivalence
177
Generic intravenous (IV) drugs are considered bioequivalent to their branded counterparts due to their 100% bioavailability upon administration. However, variations in stability among different drug products can significantly influence their therapeutic performance, even if they are pharmaceutically equivalent.Cefuroxime, a prophylactic antimicrobial, is often used as a single-dose IV injection for patients undergoing coronary artery bypass grafting surgery. A 3 g dose typically provides...
