概括
儿童早期多次全身麻醉暴露可能与智力得分降低和5岁时的神经发育问题有关. 由于研究的局限性,需要进一步的研究.
科学领域:
- 儿科麻醉学 儿科麻醉学
- 神经发育儿科 神经发育儿科
- 临床试验二次分析
背景情况:
- 婴儿 (GAS) 试验的全身麻醉或清醒区域麻醉最初在一次麻醉暴露后没有发现显著的神经发育差异.
- 超过20%的GAS试验参与者随后暴露于麻醉剂.
- 多次麻醉暴露对神经发育的影响需要进一步调查.
研究的目的:
- 为了确定多次 (≥2) 的全身麻醉暴露,与一个或没有暴露相比,是否与5岁时的不良神经发育结果有关.
- 分析GAS试验数据库中的数据,以对麻醉剂暴露和儿童发育进行二次分析.
主要方法:
- 来自GAS数据库的儿童被分为多次全身麻醉暴露和单次/无暴露组.
- 主要结局是5岁时通过韦克斯勒学前和初级智力表 (WPPSI-III) 测量的全尺度智力系数 (FSIQ).
- 二级结局包括其他神经认知测试和护理人员报告的情绪/行为评估.
主要成果:
- 患有多次麻醉剂暴露 (n=90) 的儿童在FSIQ上得分明显低于患有一次或没有暴露 (n=141) 的儿童,平均差异为-5.8分 (P=0.011).
- 多次暴露的儿童表现出较低的口头和表现智商,以及在情绪,行为和执行功能方面增加的困难.
- 该研究的观察性质意味着不能排除残留混.
结论:
- 在5岁之前多次暴露于全身麻醉剂与较差的一般智力和特定的神经发育领域有关.
- 由于样本规模较小和潜在的未经调整的混等局限性,应谨慎解释结果.
- 试验数据集可能对调查复杂关联的二次分析有局限性.

01:12Local Anesthetics: Adverse Effects
386
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

190
Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...
