Postoperative hyperalgesia does not predict persistent post-sternotomy pain; observational study based on clinical examination

摘要

BackgroundPersistent post-sternotomy pain is a common problem, but the risk of developing it varies among patients. We sought to find out whether the risk of persistent post-sternotomy pain could be predicted by measuring the area of acute sensory dysfunction around the sternotomy wound. The secondary aim was to determine risk factors for persistent post-sternotomy pain.
