Paroxysmal Sympathetic Hyperactivity

Background Paroxysmal sympathetic hyperactivity, which affects up to 10% of all acquired brain injury survivors, is characterized by elevated heart rate, blood pressure, respiratory rate, and temperature; diaphoresis; and increased posturing. Pharmacological agents that have been studied in the management of this disorder include opiates, γ-aminobutyric acid agents, dopaminergic agents, and β blockers. Although paroxysmal sympathetic hyperactivity is a relatively common complication after acquired brain injury, there is a paucity of recommendations or comparisons of agents for the management of this disorder. Objective To evaluate all relevant literature on pharmacological therapies used to manage patients with paroxysmal sympathetic hyperactivity to help elucidate possible best practices. Methods Of the 27 studies evaluated for inclusion, 10 studies received full review: 4 retrospective cohort studies, 5 single case studies, and 1 case series. Results Monotherapy is usually not effective in the management of paroxysmal sympathetic hyperactivity and multiple agents with different mechanisms of action should be considered. α2-Agonists such as dexmedetomidine may hold some slight clinical efficacy over agents like propofol, and with respect to oral medications, propranolol might convey some slight advantage compared to others. However, with the limited data available, these results must be interpreted with caution. Conclusions As the treatment of paroxysmal sympathetic hyperactivity is reactive to symptomatic evolution over time, critical care nurses play a vital role in the monitoring and treatment of these patients. Limited data exist on the management of paroxysmal sympathetic hyperactivity and larger robust data sets are needed to guide decision-making. (Critical Care Nurse. 2020;40[3]:e9-e16)

AbstractBackgroundCerebral fat embolism (CFE) syndrome at high altitude was rare complicated with paroxysmal sympathetic hyperactivity (PSH) syndrome and septic shock. It is a challenge to differential diagnosis and treatment at high altitude.Case presentationThis case presents a CFE with PSH and septic shock of a 23-year-old man occurred at high altitude of 3800 m above sea level, transferred by airplane successfully and cured in the department of neurosurgery, Xi’an Tangdu Hospital.ConclusionsIt is key that CFE with PSH can be rapid diagnosed and treatment bundles of septic shock should be initiated as soon as possible. Early neurological rehabilitation played an important role for good outcome.

Paroxysmal Sympathetic Hyperactivity

Abstract Introduction Most cases of paroxysmal sympathetic hyperactivity (PSH) result from traumatic brain injury (TBI). Little is known about its pathophysiology and treatment, and several neuroprotective drugs are used including beta-blockers. The aim of our study is to collate existing evidence of the role of beta-blockers in the treatment of PSH. Method We will search MEDLINE, Web of Science, EMBASE, Cochrane, and Google Scholar. The search terms used will cover the following terms: “paroxysmal sympathetic hyperactivity”, “traumatic brain injury” and “beta-blockers.”: No language or geographical restrictions will be applied. Two independent co-authors will screen the titles and abstracts of each article following predefined inclusion and exclusion criteria. If there is a conflict the two reviewers will find a consensus and if they cannot a third co-author will decide. Using a pre-designed and pre-piloted data extraction form, data from each included citation will be collected (authors identification, study type, TBI severity, type of beta-blockers used, dosage of the drug, clinical signs of PSH, Glasgow Coma Scale, Glasgow Outcome Scale, mortality, morbidity and length of stay). Simple descriptive data analyses will be performed and the results will be presented both in a narrative and tabular form. Results The effectiveness of beta-blockers in post-TBI PHS will be evaluated through clinical signs of PHS(increased heart rate, respiratory rate, temperature, blood pressure, and sweating), Glasgow Coma Scale, and Glasgow Outcome Scale. mortality, morbidity and length of stay. Conclusion At the end of this scoping review we will design a systematic review with metaanalysis if there are a reasonable number of studies otherwise we will design a randomized controlled trial.

Abstract Background Delayed Post Hypoxic Leukoencephalopathy (DPHL) is a syndrome that occurs after hypoxia, and can present with a variety of neuropsychiatric symptoms, including catatonia and paroxysmal sympathetic hyperactivity (PSH). The gold standard for the treatment of catatonia is electroconvulsive therapy (ECT). However, ECT can exacerbate the paroxysms of sympathetic hyperactivity and complicate recovery from DPHL. The treatment of PSH is not well established. Case presentation We present a case of a patient with multiple opiate overdoses who presented with altered mental status. He was diagnosed with catatonia and subsequently treated with ECT. His clinical condition worsened, and a revised diagnosis of PSH was established. The patient’s condition improved with medical management. Conclusion This case highlights the need to distinguish between these two related symptom clusters, as the incidence of DPHL and opioid overdose related neuropsychiatric problems increase. This distinction can greatly influence the course of treatment, and the need to consider alternative treatments.
