Insights
Nursing interventions for paroxysmal sympathetic hyperactivity (PSH) in children with severe brain injuries varied, with tactile methods most common. The Symptom Management Theory offers a framework for PSH care research.
Area of Science:
- Neurology
- Nursing Science
- Critical Care
Background:
- Paroxysmal sympathetic hyperactivity (PSH) causes autonomic instability and muscle overactivity in patients with severe brain injuries.
- Current nursing interventions for PSH are largely anecdotal and lack evidence-based support.
Purpose of the Study:
- To document nursing interventions for PSH events in children with severe brain injuries.
- To explore the application of Symptom Management Theory (SMT) as a research framework for brain injury and PSH.
Main Methods:
- Retrospective chart review of nursing progress notes from a larger study of children with severe brain injuries.
- Content analysis of verbatim nursing notes from a nested sample of ten children with PSH.
- Description of documented nursing interventions for PSH.
Main Results:
- Priority interventions included medication, family presence facilitation, and sensory (auditory, tactile, visual) stimuli management.
- Individualized interventions were administered, with varying patterns observed across subjects.
- Tactile interventions were the most frequently documented nursing approach.
Conclusions:
- There was a lack of a uniform, standardized approach to nursing interventions for PSH.
- The Symptom Management Theory (SMT) provides a valuable framework for organizing and testing clinical care strategies for PSH.
Background:
Paroxysmal sympathetic hyperactivity (PSH) produces symptoms of autonomic instability and muscle over-activity; however, the majority of nursing interventions used in clinical practice are anecdotal and not evidenced based.
Objective:
The primary objective was to report nursing documentation of PSH events, and to describe the clinical nursing interventions and care provided to children who have suffered a severe brain injury and are exhibiting PSH. The secondary objective was to demonstrate how the Symptom Management Theory (SMT) can serve as a framework for research related to brain injury and PSH.
Methodology:
The study consisted of a retrospective chart review of nursing progress notes using direct content analysis. The nested sample of ten randomly selected charts was chosen from a larger quantitative study of 83 children who had suffered severe brain injuries with and without PSH. Textual analysis of verbatim nursing progress notes was used to describe nursing interventions that were used and documented for this patient population.
Results:
The priority nursing interventions to manage these symptoms included medication administration, facilitation of family presence, and strategies to target auditory, tactile, and visual stimuli. The sample received different individual interventions for PSH. Additionally, individual subjects demonstrated different patterns of interventions.
Implications:
While tactile interventions were documented most frequently, there was not a uniform approach to interventions. The SMT can be useful to provide a framework that organizes and tests clinical care and management of PSH strategies.

Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
