In this issue of the Scandinavian Journal of Pain Hagerdorn and Atallah publish an educational case report on their experience treating highly selected patients suffering from longstanding apparently intractable CRPS with intrathecal pump-administration of morphine and bupivacaine [1]. The patient had failed to obtain pain relief or had intolerable side effects during trial of several oral drugs that are often tried, but are only occasionally effective [2]. She also had a failed spinal cord stimulator trial.
Multimodal, multidisciplinary approach with cognitive behavioural techniques may help some patients cope better. Children with CRPS appear to benefit more often from such approaches, at least compared with adult patients with longstanding CRPS with complicating comorbidities. However, it is increasingly apparent that children, who apparently were cured of their CRPS during multidisciplinary psychosocial care, have recurrent CRPS episodes later in life [3,4,5]. Case-histories of such patients indicate that CRPS patients have lasting changes in their central pain modulating systems. Such pathological changes in the fundamental regulations of the ability to sense and modulate nociceptive impulses appear to be important in the conundrum that intractable CRPS is. These mechanisms, that make most of us benefit from the nociceptive alarm and defence mechanisms of our nervous system, they ensure that we are not left with chronic pain after an acute pain-event.
These defence systems likely depend on multiple mechanisms in our central nervous system. It is a bit naïve to believe that multidisciplinary psychosocial and behavioural approaches can help all patients with CRPS. It is a problem that most invasive interventions, except maybe spinal cord stimulation, have been considered by some authorities to be more or less mal-practice. Striking educational case reports [1,3,4,5] remind us that there still is a place for invasive techniques, and not only for intractable cancer pain in palliative medicine [6,7].Although a variety of drugs can be effective in intrathecal infusions [1], the local anaesthetic and opioid receptor agonist components appear to be essential [1,4,6].
