背景:围全膝关节置换期疼痛处理一直是临床所关注的重点问题,寻找安全有效的镇痛方式,成为关节外科医生的重要任务之一。 目的:比较硬膜外镇痛和股神经阻滞镇痛在患者全膝关节置换后镇痛、康复的效果,探索相关的多模式联合镇痛方案。 方法:随机选取行单侧膝关节置换的患者40例,按照镇痛方案的不同分为硬膜外镇痛组和股神经阻滞镇痛组,每组20例。患者在连续硬膜外麻醉下进行单侧膝关节置换并进行术前宣教和塞来昔布给药。置换后硬膜外镇痛组通过留置导管连接0.2%罗哌卡因、2 mg/L芬太尼止痛泵镇痛;股神经阻滞镇痛组通过股神经阻滞导管间断注射0.2%罗哌卡因镇痛。观察全膝关节置换后患者6,12,24 h和2-7 d每天的疼痛程度,以及2-7 d每天的膝关节活动度。 结果与结论:全膝关节置换后2-7 d,2组患者每天的静息痛和活动痛的目测类比评分均呈下降的趋势,股神经阻滞镇痛组患者的疼痛程度小于硬膜外镇痛组患者。置换后2-7 d,股神经阻滞镇痛组和硬膜外镇痛组患者膝关节活动度都逐渐升高,股神经阻滞镇痛组患者膝关节活动度大于硬膜外镇痛组。结果说明虽然硬膜外镇痛和股神经阻滞镇痛都能缓解全膝关节置换术后疼痛,但股神经阻滞镇痛在全膝关节置换后近期的运动镇痛效果优于硬膜外镇痛,能加快患者关节功能的康复,且多模式联合镇痛方案能有效控制疼痛。  相似文献

Methods for evaluating analgesic effect for spontaneous pain are increasingly important because it is reported by most patients with neuropathic pain. The present study assessed the analgesic effects of periaqueductal gray (PAG) stimulation in the spared nerve injury (SNI) model of neuropathic pain of the rat. Spontaneous rapid paw withdrawal movements were used as the index of spontaneous pain. Deep-brain stimulation in the PAG was performed in rats 3 weeks after SNI. Significant analgesic effects on spontaneous pain behavior were observed at the same stimulation parameter that reversed the reduced mechanical threshold of the von Frey test. Both analgesic effects lasted 30-40min beyond the 3min stimulation period. In summary, PAG stimulation was effective in alleviating spontaneous pain and mechanical allodynia in the SNI rat. The frequency of spontaneous paw lifting, a behavioral index of spontaneous pain used in this study, will be useful for future testing of therapeutic methods.  相似文献

BACKGROUND: Chronic widespread pain is common in the community but is not often diagnosed in primary care. One explanation may be that widespread pain is presented and treated in primary care as multiple episodes of regional pain. AIM: To determine whether patients who consult with multiple regional pain syndromes have characteristics consistent with chronic widespread pain. DESIGN OF STUDY: Case-control study. SETTING: One general practice in North Staffordshire, UK. METHOD: Participants were 148 cases who consulted regularly with different musculoskeletal pains over 5 years, and 524 controls who had not consulted for musculoskeletal pain during the same period. A postal questionnaire survey and medical record review were undertaken. RESULTS: Cases with musculoskeletal pain reported more health problems and higher levels of fatigue than controls, and significantly worse general health and greater sleep disturbance (odds ratios 3.3. and 3.1, respectively). They generally reported more severe symptoms and consulted more frequently for a range of problems, but this was not explained by a general propensity to consult. CONCLUSION: Patients who consult in primary care with multiple regional pain syndromes have similar characteristics to those associated with chronic widespread pain and fibromyalgia. Recognising the need for general approaches to pain management, rather than treating each syndrome as a regional problem of pain, may improve the outcome in such patients.  相似文献

The habenula is a small bilateral structure in the posterior-medial aspect of the dorsal thalamus that has been implicated in a remarkably wide range of behaviors including olfaction, ingestion, mating, endocrine and reward function, pain and analgesia. Afferent connections from forebrain structures send inputs to the lateral and medial habenula where efferents are mainly projected to brainstem regions that include well-known pain modulatory regions such as the periaqueductal gray and raphe nuclei. A convergence of preclinical data implicates the region in multiple behaviors that may be considered part of the pain experience including a putative role in pain modulation, affective, and motivational processes. The habenula seems to play a role as an evaluator, acting as a major point of convergence where external stimuli is received, evaluated, and redirected for motivation of appropriate behavioral response. Here, we review the role of the habenula in pain and analgesia, consider its potential role in chronic pain, and review more recent clinical and functional imaging data of the habenula from animals and humans. Even through the habenula is a small brain structure, advances in structural and functional imaging in humans should allow for further advancement of our understanding of its role in pain and analgesia.  相似文献

Numerous studies indicate that morphine suppresses pain-evoked activities in both spinal and supraspinal regions. However, little is known about the effect of morphine on the basal brain activity in the absence of pain. The present study was designed to assess the effects of single-dose morphine on the spontaneous discharge of many simultaneously recorded single units, as well as their functional connections, in the lateral pain pathway, including the primary somatosensory cortex (SI) and ventral posterolateral thalamus (VPL), and medial pain pathway, including the anterior cingulate cortex (ACC) and medial dorsal thalamus (MD), in awake rats. Morphine (5 mg/kg) was administered intraperitoneally before the recording. Naloxone plus morphine and normal saline injections were performed respectively as controls. The results showed that morphine administration produced significant changes in the spontaneous neuronal activity in more than one third of the total recorded neurons, with primary activation in the lateral pathway while both inhibition and activation in the medial pathway. Naloxone pretreatment completely blocked the effects induced by morphine. In addition, the correlated activities between and within both pain pathways was exclusively suppressed after morphine injection. These results suggest that morphine may play different roles in modulating neural activity in normal vs. pain states. Taken together, this is the first study investigating the morphine modulation of spontaneous neuronal activity within parallel pain pathways. It can be helpful for revealing neuronal population coding for the morphine action in the absence of pain, and shed light on the supraspinal mechanisms for preemptive analgesia.  相似文献

The development of chronic pain involves increased sensitivity of peripheral nociceptors and elevated neuronal activity in many regions of the central nervous system. Much of these changes are caused by the amplification of nociceptive signals resulting from the modulation and altered expression of specific ion channels and receptors in the central and peripheral nervous system. Understanding the processes by which these ion channels and receptors are regulated and how these mechanisms malfunction may lead to new treatments for chronic pain. Here we review the contribution of the Ca2+-permeable acid-sensing ion channel (ASICCa) in the development and persistence of chronic pain, and the potential underlying mechanisms. Accumulating evidence suggests that ASICCa represents an attractive new target for developing effective therapies for chronic pain.  相似文献

Although neuroimmune interactions associated with the development of pain sensitization in models of neuropathic pain have been widely studied, there are some aspects that require further investigation. Thus, we aimed to evaluate whether the local intraneural or perineural injections of dexamethasone, an efficacious anti-inflammatory and immunosuppressant drug, delays the development of both thermal hyperalgesia and mechanical allodynia in an experimental model of neuropathic pain in rats. Hargreaves and electronic von Frey tests were applied. The chronic constriction injury (CCI) of right sciatic nerve was performed. Single intraneural dexamethasone administration at the moment of constriction delayed the development of sensitization for thermal hyperalgesia and mechanical allodynia. However, perineural administration of dexamethasone, at the highest dose, did not delay experimental pain development. These results show that inflammation/immune response at the site of nerve lesion is an essential trigger for the pathological changes that lead to both hyperalgesia and allodynia. In conclusion, this approach opens new opportunities to study cellular and molecular neuroimmune interactions associated with the development of pain derived from peripheral neuropathies.  相似文献
