Emotional numbing and pain intensity predict the development of pain disability up to one year after lateral thoracotomy.

摘要: Little is known about the factors that predict transition of acute, time limited pain to chronic pathological following postero-lateral thoracotomy. The aim present prospective, longitudinal study was determine extent which (1) pre-operative intensity, disability, and post-traumatic stress symptoms (PTSS) post-thoracotomy disability 6 12 months later; (2) if these variables, assessed at months, month disability. Fifty-four patients scheduled undergo thoracotomy for intrathoracic malignancies were recruited before surgery followed prospectively one year. incidence 68.1% 61.1% follow-ups, respectively. Multiple regression analyses showed neither nor acute movement-evoked post-operative predicted or However, concurrent intensity emotional numbing, but not avoidance symptoms, made unique, significant contributions explanation each follow-up (total R(2)=76.3.0% 63.9% respectively, both p<0.0009). relative contribution decreased, while numbing increased with time, indicating a progressive de-coupling concomitant strengthening link between This suggests may serve as traumatic stressor causes numbing. results also support recent suggestions constitute separate PTSS clusters. Further research required source(s) after effective interventions.
