概括
在心脏骤停 (CA) 后的儿童中,后毒性肌肉发作 (PHM) 是常见的,影响了9% 的患者. 这种情况与大脑损伤和死亡率的增加有关,这突显了其在儿科重症监护中的重要性.
科学领域:
- 儿童重症监护医疗
- 神经科学
- 神经学
背景情况:
- 在心脏骤停 (CA) 后,已知Phypoxic Myoclonus (PHM) 是一个不良预后指标.
- 在儿童群体中对PHM的研究有限.
- 了解儿童的PHM对于改善结果至关重要.
研究的目的:
- 在CA后确定儿科患者PHM的发生率.
- 描述与PHM相关的脑电图 (EEG) 的特征.
- 评估儿童PHM的结果,包括死亡率和脑损伤.
主要方法:
- 在3年内对106名儿科患者进行了回顾性单中心审查.
- 排除患有先前脑损伤,或接受ICU治疗的患者.
- 基平方分析以评估PHM与死亡率和脑损伤的相关性.
主要成果:
- 在9% (10/106) 的儿科CA患者中发现了PHM.
- 患有PHM的患者的脑损伤率显著上升 (100%对53%) 和死亡率 (90%对38%).
- 当将PHM患者与脑损伤或严重EEG异常患者进行比较时,没有观察到死亡率的显著差异.
结论:
- 在心脏骤停后的儿科患者中经常出现PHM.
- 在这一群体中,PHM与大脑损伤和死亡率的增加密切相关.
- 存在PHM表明严重的神经损伤心脏骤停后.

Seizures: Classification
582
Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Epilepsy and Seizures: Overview
274
Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

Electrocardiogram
3.2K
An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.
