What is the initial approach to managing quadriparesis?

Initial Approach to Managing Quadriparesis

The initial approach to managing quadriparesis should focus on immediate spine immobilization, airway management, hemodynamic stabilization, and prevention of secondary injury to maximize neurological recovery and improve long-term outcomes. 1

Immediate Stabilization

• Early immobilization of the spine is recommended for any patient with suspected spinal cord injury to limit the onset or aggravation of neurological deficit 2, 1
• For patients with cervical spinal cord injury, manual in-line stabilization combined with removal of the anterior part of the cervical collar during intubation procedures is suggested to limit cervical spine movement while promoting glottic exposure 2, 1
• Pre-hospital tracheal intubation should follow a procedure integrating rapid induction with direct laryngoscopy, use of a gum elastic bougie, and retention of the cervical spine in the axis without Sellick maneuver to increase first-attempt success rate 2, 1

Respiratory Management

• Early identification and management of respiratory complications is essential, particularly in high cervical injuries (above C5) which commonly affect diaphragmatic function 1
• Tracheostomy should be considered when prolonged airway support is anticipated, particularly when residual vital capacity is significantly decreased 1
• Early tracheostomy (< 7 days) may reduce ICU hospitalization times and the incidence of laryngeal complications due to prolonged intubation 1

Hemodynamic Management

• Maintaining adequate spinal cord perfusion is critical to prevent secondary injury and promote neurological recovery 1
• Target mean arterial pressure (MAP) goals should be maintained to ensure adequate spinal cord perfusion 1
• Avoid fluid overload in patients with pulmonary hypertension and right heart failure; use blood products rather than crystalloid or colloid fluids for volume resuscitation 2
• Vasopressors may be necessary to achieve hemodynamic stability 1

Diagnostic Evaluation

• Urgent imaging with MRI of the spine is essential to identify the cause and level of quadriparesis 3, 4
• Consider CT scan when MRI is not immediately available or to better visualize bony structures 5
• Laboratory tests should include electrolytes, as severe hypokalemia can present with quadriparesis and is rapidly reversible with potassium replacement 6
• Evaluate for other potential causes including Guillain-Barré syndrome, which requires different management approaches 2

Pharmacological Management

• High-dose methylprednisolone may be considered in specific cases of acute spinal cord injury 7, 3
• When administering high doses of methylprednisolone, monitor for potential complications including:
  • Cardiac arrhythmias with rapid administration (greater than 0.5 gram over less than 10 minutes) 7
  • Increased risk of infection 7
  • Hypokalemia, which can worsen weakness 7, 6
  • Gastrointestinal complications including peptic ulcers 7

Prevention of Secondary Complications

• Implement measures to prevent pressure ulcers from the acute phase, including early mobilization once the spine is stabilized, visual and tactile checks of all areas at risk at least once daily, and repositioning every 2-4 hours 1
• Intermittent urinary catheterization is recommended as soon as the volume of daily diuresis is adequate to reduce urological complications 1
• Self-intermittent urethral catheterization is recommended by national and international neuro-urology societies 1
• Indwelling catheters should be removed as soon as the patient is medically stable to minimize urological risks 1

Pain Management

• Implement multimodal analgesia combining non-opioid analgesics, antihyperalgesic drugs (ketamine), and opioids during acute management 1
• For neuropathic pain, oral gabapentinoids are recommended for more than 6 months, with the addition of tricyclic antidepressants or serotonin reuptake inhibitors when monotherapy is inefficient 1

Early Rehabilitation

• Early rehabilitation should begin immediately after stabilization to maximize neurological recovery 1
• Physical exercise plays a major role in enhancing regeneration of the central nervous system through the elaboration of neurotrophic factors 1
• Stretching techniques should be performed for at least 20 minutes per zone and completed by simple posture orthosis and proper bed and chair positioning 1
• For incomplete injuries, gravity-assisted ambulation or body weight support with treadmill training can improve walking outcomes 1

Common Pitfalls to Avoid

• Delaying immobilization in suspected spinal cord injury cases can lead to worsening neurological outcomes 1
• Inadequate pain management can lead to chronic pain syndromes that are difficult to treat 1
• Neglecting early rehabilitation can result in preventable complications and poorer functional outcomes 1
• Failing to implement pressure ulcer prevention strategies can lead to significant morbidity 1
• Overlooking reversible causes of quadriparesis such as electrolyte abnormalities (particularly hypokalemia) 6
• Administering high-dose steroids too rapidly, which can cause cardiac arrhythmias 7
