Abstract:
The clinical manifestations of paroxysmal sympathetic hyperactivity
(PSH) after severe craniocerebral injury are very similar to those of grand mal
seizures, which are easily misdiagnosed in the early stage, resulting in
further irreversible brain damage. By comparing the similarities in clinical
manifestations, seizure mechanism, drug treatment, and other differences of the
above two, PSH can be identified clinically early. In this article, the common
clinical manifestations and differences between PSH and grand mal seizures are
listed by referring to relevant literature and combined with the nursing
observation of PSH patients in the Department of Neurosurgery, the First
Affiliated Hospital, Zhejiang University, School of Medicine in the past two
years. Our research shows that PSH is a clinical syndrome that appears after a
variety of acute brain injuries and is mainly characterized by hyperexcitatory
sympathetic nerves. The clinical manifestations of PSH are complex and
difficult to identify. Raising awareness of the syndrome is helpful for its
early diagnosis and treatment.
