概括
这项研究开发了三种卡巴耐药性评分,以确定患有血性恶性瘤的高风险患者. 超过2. 5的分数可靠地预测耐卡巴的格拉姆阴性细菌感染,有助于治疗决定.
科学领域:
- 传染性疾病
- 血液学
- 临床微生物学
背景情况:
- 耐卡巴胺的格拉姆阴性细菌感染 (GNBIs) 构成重大威胁,特别是在免疫受损的患者中.
- 血液性恶性瘤增加了对严重感染的易感性,包括GNBIs.
研究的目的:
- 在患有血性恶性瘤的患者中开发和验证格拉姆阴性细菌感染 (GNBIs) 的抗卡巴因分数.
- 确定与这种脆弱人群中的卡巴耐药性相关的关键临床风险因素.
主要方法:
- 一项比较研究包括154名在医院获得的GNBIs患者 (64名耐卡巴,90名易受).
- 单变量和多变量分析发现了显著的风险因素.
- 使用统计学意义上的变量构建了三种不同的碳烯耐药性风险评分模型.
主要成果:
- 卡巴胺耐药性的重要危险因素包括以前使用化醇/ 卡巴胺,有史以来对卡巴胺耐药性感染,直肠 *Klebsiella pneumoniae* 定居,长时间住院 (≥30天) 和尿导管存在.
- 开发了三种模型,其中常见的因素是诺的使用,直肠*K.肺炎*的殖民化和尿导管. 第四个变量在不同模型中不同.
- 所有模型都表现出强烈的分辨能力 (AUC> 0.82),截止分数> 2. 5有效识别高风险患者.
结论:
- 成功开发了三种实用的风险评分模型,用于预测血液恶性瘤患者的卡巴因耐药性.
- 切断分数>2.5是确定高风险患者的可靠值.
- 这些评分为临床医生提供了一种有价值的工具,用于指导高危人群的实证抗生素治疗.

01:11Renal Failure: Dose Adjustments
153
In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...
