Algorithm for multimodal medication therapy in patients with complex regional pain syndrome

Area of Science:

• Neurology
• Pain Management
• Pharmacology

Background:

• Complex Regional Pain Syndrome (CRPS) presents with neuropathic pain, autonomic dysfunction, motor deficits, and trophic changes.
• Severe CRPS pain often persists and progresses to chronic stages despite current treatments.
• Understanding CRPS pathology is crucial for developing effective therapeutic strategies.

Purpose of the Study:

• To construct a multimodal medication therapy algorithm for managing CRPS pain.
• To provide clinicians with a structured approach for treating CRPS based on its underlying pathology.
• To address persistent and severe pain in both acute and chronic phases of CRPS.

Main Methods:

• Developed a treatment algorithm based on CRPS pathology.
• Recommended oral steroid pulse therapy for initial pain management.
• Outlined sequential treatment escalation including central sensitization modulators, ketamine with midazolam, and intravenous lidocaine for refractory cases.

Main Results:

• The proposed algorithm integrates oral steroid pulse therapy to reduce neuroinflammation.
• It addresses central sensitization for chronic CRPS pain.
• It includes advanced interventions like ketamine and lidocaine for treatment-resistant pain.

Conclusions:

• The developed drug treatment algorithm offers a systematic approach to managing CRPS pain.
• This algorithm aims to improve clinical treatment of patients with CRPS.
• Further clinical studies are needed to validate and establish this algorithm in practice.
