title: Does vitamin C prevent the occurrence of complex regional pain syndrome in patients with extremity trauma requiring surgery?
abstract: The complex regional pain syndrome is a neuroinflammatory pathology that affects the central and peripheral nervous system, characterized by disproportional pain in relation to the trauma experimented by the patient. It has been proposed that vitamin C could prevent the development of this syndrome in patients with limb trauma and surgery. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified two systematic reviews that indentified four primary studies, including one randomized controlled trial. We generated a summary of findings table following the GRADE approach. We concluded it is uncertain whether vitamin C prevents complex regional pain syndrome because the certainty of the evidence is very low.
