项目摘要
PROJECT SUMMARY
Surgery is an increasingly common event, impacting over 230 million people annually. Post-surgical
pain is variable in severity and duration, but a significant minority (20-30%) of patients experience surgical site
pain lasting a year or longer. Such persistent postsurgical pain causes physical and mental suffering and
disability, and long exposure to postoperative opioids also puts patients at risk of misuse and addiction.
Despite excellent preclinical research into the molecular events involved in the transition of acute to chronic
pain after injury, little success at translating these findings to actual prevention of persistent postoperative pain
in human patients has been realized. My research program has focused on building a working human model of
this transition, by systematic and longitudinal study of pain before, during and after a variety of surgeries.
Importantly, we have focused our efforts to identify risk factors to predict those who will actually develop
chronic postsurgical pain, rather than those who won’t (70-80%), to make study of this problem more efficient.
A crucially important factor in determining the trajectory of post-surgical pain appears to be the capacity
for amplification in the circuitry of the pain system, whereby incoming painful input may be increased to the
point of intense discomfort. This amplification may be protective in the short term, but dysfunctional if it is
excessive or persistent. In our psychophysics lab, we study measures that indicate an excessive (temporal
summation of pain, TSP) or prolonged response (painful after sensations, PAS) amplification response of the
nervous system in response to standardized pain stimuli. Amplification can also occur at a psychosocial level,
where stress, sleep disruption, and catastrophizing (a mental process by which rumination, magnification, and
worry increase salience and importance) increase pain perception. Importantly. TSP, PAS, stress, sleep
disturbance and catastrophizing are much more prominent in some individuals, and account for a sizeable
amount of the variation in postsurgical pain severity (and far more than the surgical extent). We have adapted
these tests to easily and non-invasively test this “amplification phenotype” in individuals BEFORE they have
surgery, using modified bedside quantitative sensory tests (QSTs), and brief, validated questionnaires.
We propose to use these measures of preoperative amplification phenotype, in order to help target
both known and novel non-opioid preventive treatments to those individuals who need them most. This is my
area of expertise, as I am an anesthesiologist with formal training in pain neuroscience, psychophysical and
psychosocial assessment, and practical experience in conducting translational studies in post-surgical pain.
Broadly, my research plan will use this human translational pain model: 1) to speed testing of pain preventive
therapies, 2) to develop strategies to reduce pain and opioid use after surgery in high risk individuals, and 3) to
forward personalized medicine in the perioperative period. Providing precision medical care and preventing
chronic postsurgical pain and opioid use will ultimately improve health care for patients, and lower its cost.
项目概要
手术越来越普遍,每年影响超过 2.3 亿人。术后
疼痛的严重程度和持续时间各不相同,但极少数 (20-30%) 的患者会经历手术部位的疼痛
疼痛持续一年或更长时间。这种持续的术后疼痛会导致身体和精神上的痛苦,
残疾以及术后长期接触阿片类药物也使患者面临误用和成瘾的风险。
尽管对急性向慢性转变所涉及的分子事件进行了出色的临床前研究
受伤后疼痛,但在将这些发现转化为实际预防术后持续疼痛方面收效甚微
在人类患者中已经实现。我的研究项目重点是建立一个工作人类模型
通过对各种手术之前、期间和之后的疼痛进行系统和纵向研究来实现这一转变。
重要的是,我们集中精力识别风险因素,以预测那些真正会发展的人
慢性术后疼痛,而不是那些不会的人(70-80%),以使对该问题的研究更加有效。
决定术后疼痛轨迹的一个至关重要的因素似乎是能力
用于放大疼痛系统的电路,从而可以将传入的疼痛输入增加到
强烈不适的点。这种放大在短期内可能是保护性的,但如果是的话,就会发挥功能障碍。
过度或持续。在我们的心理物理学实验室,我们研究表明过度(时间
疼痛总和(TSP)或延长反应(感觉后疼痛,PAS)放大反应
神经系统对标准化疼痛刺激的反应。放大也可能发生在心理社会层面,
压力、睡眠中断和灾难化(一种沉思、放大和灾难性的心理过程)
担心会增加显着性和重要性)增加疼痛感知。重要的是。 TSP、PAS、压力、睡眠
干扰和灾难化在某些个体中更为突出,并且占相当大的比例。
术后疼痛严重程度的变化量(并且远远超过手术范围)。我们已经适应了
这些测试可以轻松且非侵入性地测试个体的这种“扩增表型”
手术,使用改良的床边定量感觉测试(QST)和简短的、经过验证的问卷。
我们建议使用这些术前扩增表型的测量方法,以帮助靶向
为最需要的人提供已知的和新颖的非阿片类药物预防性治疗。这是我的
专业领域,因为我是一名麻醉师,接受过疼痛神经科学、心理物理学和
心理社会评估以及进行术后疼痛转化研究的实践经验。
总的来说,我的研究计划将使用这种人类转化疼痛模型:1)加速疼痛预防的测试
疗法,2) 制定策略以减少高危人群手术后的疼痛和阿片类药物的使用,以及 3)
推进围手术期个性化医疗。精准医疗、预防为主
慢性术后疼痛和阿片类药物的使用最终将改善患者的医疗保健,并降低其成本。
