疼痛灾难化预测术后疼痛的研究进展

Research progress on pain catastrophizing for the prediction of postoperative pain

疼痛灾难化是患者对疼痛产生的夸大且消极的思维定势。作为与疼痛相关的主要负面心理情绪之一,疼痛灾难化可以通过多种机制调控疼痛体验。因此,疼痛灾难化可能是各种疼痛相关疾病的潜在发病机制和治疗靶点。近年来,由于相对统一的量表出现,越来越多的研究将疼痛灾难化作为术前心理评估项目,探讨术前疼痛灾难化强度预测术后疼痛发生的可能性。全文对疼痛灾难化的相关概念、发生机制、评估手段以及疼痛灾难化对术后急慢性疼痛的预测能力的研究进展进行综述。

Pain catastrophizing is an exaggerated and negative thinking set which is triggered by pain.As one of the vital adverse feelings related to pain,it can regulate the degree of pain experience by a battery of mechanisms.Thus,pain catastrophizing is possibly a potential pathogenesis and therapeutic target for pain-related diseases.Recently,with the appearance of relatively uniform scale,an increasing number of investigations choose pain catastrophizing as part of psychological assessment preoperatively,aiming at the probability that the degree of pain catastrophizing could predict the occurrence of postoperative pain.In this article,we reviewed the progress on the relevant concepts of pain catastrophizing altogether with its possible mechanisms,evaluation methods,and capability to predict postoperative acute and chronic pain,which may provide references for clinical therapies or scientific researches focused on pain catastrophizing.
