OBJECTIVE: This prospective study investigated and analyzed the clinical characteristics and prognosis of paroxysmal sympathetic hyperactivity (PSH) in patients with severe nontraumatic brain injury.
METHODS: Patients presenting with severe nontraumatic brain injury with PSH from July 2018 to June 2019 were enrolled. A PSH assessment measure ≥ 8 points was used as the criterion for PSH. Clinical data, indicators related to PSH, treatment effects and the prognosis were prospectively collected and analyzed.
RESULTS: A total of 220 patients with severe nontraumatic brain injury were analyzed, and PSH occurred in 8 patients (3.6%). The primary neurological diseases included acute cerebral infarction, anti-N-methyl-D-aspartate receptor encephalitis, hypoxic encephalopathy and acute disseminated encephalitis. The Glasgow Coma Scale score was lower than 8 in the 8 patients with PSH. Seven of these eight patients had a Glasgow outcome scale (GOS) score of 3 or less than 3, and one patient had a GOS of 5 after 6 months. The medicines that effectively controlled PSH included dexmedetomidine, clonazepam, midazolam and diazepam.
CONCLUSIONS: Although the incidence was lower for nontraumatic brain injury complicated with PSH than for traumatic brain injury, patients with PSH had a more severe disease state and poorer prognoses. Dexmedetomidine might effectively control PSH.
