What is the management for diaphoresis and muscle spasms after a Traumatic Brain Injury (TBI)?

From the Guidelines

Management of diaphoresis and muscle spasms after traumatic brain injury (TBI) should prioritize a multifaceted approach, focusing on symptom reduction and individualized treatment plans, as outlined in recent guidelines 1. The approach to managing diaphoresis and muscle spasms after TBI involves understanding the underlying causes, which often include autonomic dysregulation and damage to brain areas controlling muscle tone.

Key Considerations

• Diaphoresis, resulting from autonomic dysregulation, can be managed with antipyretics like acetaminophen and anticholinergics such as glycopyrrolate, alongside environmental modifications to reduce sweating 1.
• Muscle spasms can be addressed with baclofen as a first-line agent, with alternatives including tizanidine, diazepam, or dantrolene, and should be complemented with physical therapy incorporating stretching and positioning 1.

Treatment Approach

• Individualized treatment plans are crucial, considering the severity of symptoms and the potential for side effects such as sedation, hypotension, or cognitive impairment, which can be particularly problematic in TBI patients 1.
• Close monitoring of patients is essential to adjust treatment plans as necessary and to minimize adverse effects.
• The use of medications should be guided by the most recent and highest quality evidence, with consideration of the patient's overall clinical condition and potential interactions with other treatments.

Guidelines and Evidence

• Recent guidelines, such as those published in 2018 by the French Society of Anaesthesia and Intensive Care Medicine 1, provide a framework for the management of severe TBI, including the evaluation of initial severity, prehospital management, and medical management of raised intracranial pressure.
• These guidelines, developed using the GRADE method, offer recommendations on various aspects of TBI management, including sedation, analgesia, and the prevention of post-traumatic seizures.

From the FDA Drug Label

Tizanidine’s capacity to reduce increased muscle tone associated with spasticity was demonstrated in two adequate and well controlled studies in patients with multiple sclerosis or spinal cord injury. The reduction in muscle tone was not associated with a reduction in muscle strength (a desirable outcome) but also did not lead to any consistent advantage of tizanidine treated patients on measures of activities of daily living.

The management for muscle spasms after a Traumatic Brain Injury (TBI) may include the use of tizanidine, as it has been shown to reduce increased muscle tone associated with spasticity. However, there is no direct information in the provided drug label about the management of diaphoresis after TBI.

• Tizanidine may be used to manage muscle spasms, but its effectiveness in patients with TBI is not directly addressed in the label.
• The use of tizanidine should be approached with caution, particularly in renally impaired patients or those taking oral contraceptives, as it may lead to adverse events such as hypotension 2.

From the Research

Management of Diaphoresis and Muscle Spasms after TBI

• Diaphoresis and muscle spasms are common complications after Traumatic Brain Injury (TBI) 3
• These symptoms can be part of a larger condition known as Paroxysmal Sympathetic Hyperactivity (PSH), which is characterized by hyperthermia, hypertension, tachycardia, tachypnea, diaphoresis, dystonia, and motor features such as extensor/flexor posturing 3

Pharmacological Interventions

• Baclofen, a muscle relaxant, has been used to treat spasticity and improve mobility in patients with TBI 4, 5, 6
• However, the effectiveness of baclofen in managing diaphoresis and muscle spasms after TBI is still uncertain due to limited and low-quality evidence 4
• Other pharmacological interventions, such as botulinum toxin A, have also been used to manage spasticity after TBI, but more research is needed to determine their effectiveness 4

Non-Pharmacological Interventions

• Non-pharmacological interventions, such as physiotherapy, casting, and electrical stimulation, have been used to manage spasticity after TBI, but their effectiveness is also uncertain due to limited evidence 4
• A multidisciplinary approach, including physical, occupational, and speech therapy, may be necessary to manage the complex symptoms associated with TBI 4

Identification and Management of PSH

• Early identification and management of PSH are crucial to prevent secondary brain injury and improve outcomes after TBI 3
• A framework for symptomatic management of PSH includes eliminating predisposing causes, mitigating excessive sympathetic outflow, and supportive therapy 3
• Further research is needed to develop effective treatments for PSH and to improve our understanding of its pathophysiology 3
