概括

脑干死亡的诊断通常是指固定瞳孔. 一个罕见的病例显示脑死亡患者的瞳孔振荡,这是一个外围现象,不应该延迟器官捐献的诊断.

科学领域:

神经学神经学
眼科医生眼科眼科

背景情况:

扩张和固定瞳孔是诊断脑干死亡的关键指标.
非典型的瞳孔反应可能会使诊断过程复杂化.

研究的目的:

在脑死亡患者中报告一种罕见的单边振荡瞳孔活动.
澄清这种现象对脑干死亡确认和器官捐献的诊断影响.

主要方法:

一个脑死亡患者的病例报告,患有不典型的瞳孔运动.
通过辅助测试排除核心原因,确认脑干死亡.

主要成果:

患者表现出单方面的,自发的,反复的瞳孔振荡 (扩张和收缩),对光无反应.
这种现象被确定为外围起源,可能是由于过敏的瞳孔肌肉或终端神经放电导致交感刺激.

结论:

在脑干死亡患者中,动的瞳孔活动是一种罕见的外周现象,不表明中枢神经系统活动.
这种非典型的迹象不应阻碍或推迟脑干死亡的诊断,使得器官可以及时捐献.

Brainstem

Brainstem

The brainstem, located inferior to the brain and superior to the spinal cord, serves as a bridge between the cerebrum and the spinal cord. It plays a vital role in relaying information and controlling critical life functions. It comprises three primary regions: the midbrain, pons, and medulla oblongata.
The Midbrain
The midbrain is located beneath the diencephalon and connects the cerebrum with the lower parts of the brain. The cerebral peduncles are prominent midbrain structures that house the...

Brainstem: Control Centers of Medulla

The medulla oblongata is a crucial part of the brainstem responsible for controlling various autonomic and involuntary functions. It contains several nuclei, including the olivary, cuneate, gracile, and solitary nuclei.
Olivary Nucleus
The olivary nucleus, or inferior olivary nucleus, is located within the ventrolateral part of the medulla oblongata. It is primarily involved in motor coordination and motor learning. The olivary nucleus receives input from the spinal cord, cerebellum, and motor...
