Key result
Sympathetic blocks require established criteria for complete blockade to accurately assess sympathetic-sensory coupling.
Why the study?
Do sympatholytic interventions relieve pain in patients with reflex sympathetic dystrophy or sympathetically maintained pain?
Population

Pain independence from sympathetic function cannot be assumed without confirmed complete blockade; leaves open accurate sympathetic-sensory coupling assessment.
Do sympatholytic interventions relieve pain in patients with reflex sympathetic dystrophy or sympathetically maintained pain?
Pain should not be considered independent of sympathetic function until criteria for a complete sympathetic block are established and satisfied.
Blumberg et al. (1997) conducted a review in Reflex sympathetic dystrophy and sympathetically maintained pain. Sympathetic blocks was evaluated. Sympathetic blocks for pain relief in reflex sympathetic dystrophy and sympathetically maintained pain require established criteria for complete blockade to accurately assess sympathetic-sensory coupling.
