三叉神经是第5对颅神经,由眼支(第一支)、上颌支(第二支)和下颌支(第三支)汇合而成,分别支配眼裂以上、眼裂和口裂之间、口裂以下的感觉和嚼肌收缩.血管压迫是三叉神经痛的主要致病原因,约95%~98%三叉神经痛的原发性患者在术中能找到压迫血管[1].治疗三叉神经痛的手段主要有药物治疗、封闭治疗和手术治疗3种.大部分患者在药物治疗无效后可行三叉神经局部封闭术,但术后面部麻木发生率及复发率均较高,并非理想的治疗方法.三叉神经痛是终生携带性疾病,症状常随着年龄的增长逐渐加重.2010年1月至2011年12月,我科对96例三叉神经痛患者实施微血管减压术获得满意效果.现将护理体会报告如下. 相似文献

OBJECTIVES: Arterial compression of the trigeminal root may lead to trigeminal neuralgia. 5-HT1B/1D receptor agonists may inhibit vasodilation and inflammation near the irritated trigeminal root. A recent study showed attenuation of mechanical allodynia by a 5-HT1A receptor agonist in a rat model of trigeminal neuralgia. The present study examined the effectiveness of a 5-HT1A/1B/1D receptor agonist, sumatriptan, on pain relief in patients with trigeminal neuralgia. METHODS: The study was conducted in 15 patients with idiopathic trigeminal neuralgia. The patients had been suffering from painful paroxysms for at least 1 month. Each patient was injected with 1 mL of saline subcutaneously (placebo), followed 15 minutes later with subcutaneous sumatriptan (3 mg in 1 mL saline). This was followed the next day by oral sumatriptan (50 mg twice daily) for 1 week. RESULTS: The visual analog scale did not change after saline, but significantly decreased after subcutaneous sumatriptan. Both 1 week after oral sumatriptan and 1 week after discontinuation of the drug, visual analog scale scores resulted in a significant decrease from the baseline. Adverse events after subcutaneous sumatriptan occurred in 4 patients: fatigue in 4 and nausea in 2. Side effects from the oral medication appeared in 4 patients: fatigue in 2, nausea in 1 and chest discomfort in 1. These side effects subsided soon after discontinuation of sumatriptan. CONCLUSIONS: Our results indicate that subcutaneous injection followed by oral administration of sumatriptan produces prompt and continuous analgesia in patients with trigeminal neuralgia. 相似文献

[Purpose] The number of patients with attention deficit hyperactivity disorder has been increasing. These patients show low activity in the prefrontal cortex, which can be improved by pharmacotherapy and neurofeedback training. This exploratory study aimed to examine whether the hemodynamic response in the prefrontal cortex during an inhibition response in patients with attention deficit hyperactivity disorder tendencies increased after interpersonal counseling. [Participants and Methods] Participants (n=5) received three interpersonal counseling sessions. Interpersonal counseling focuses on the patient’s current problems and devises specific coping strategies, and it can be performed by healthcare personnel such as physiotherapists. Prefrontal cortex activity during a suppression reaction task was measured by using near-infrared spectroscopy at baseline and post-interpersonal counseling. The outcome was a difference in the oxyhemoglobin level from baseline to post-interpersonal counseling. [Results] The oxyhemoglobin level in the prefrontal cortex significantly increased post-interpersonal counseling. [Conclusion] These results suggested that interpersonal counseling could improve the hemodynamic response in the prefrontal cortex under inhibition in individuals with attention deficit hyperactivity disorder tendencies, suggesting that interpersonal counseling may be effective for treating attention deficit hyperactivity disorder symptoms. 相似文献

Background
Transcranial direct current stimulation (tDCS) of the primary motor cortex has been shown to modulate pain and trigeminal nociceptive processing.Methods
Ten patients with classical trigeminal neuralgia (TN) were stimulated daily for 20 minutes over two weeks using anodal (1 mA) or sham tDCS over the primary motor cortex (M1) in a randomized double-blind cross-over design. Primary outcome variable was pain intensity on a verbal rating scale (VRS 0–10). VRS and attack frequency were assessed for one month before, during and after tDCS. The impact on trigeminal pain processing was assessed with pain-related evoked potentials (PREP) and the nociceptive blink reflex (nBR) following electrical stimulation on both sides of the forehead before and after tDCS.Results
Anodal tDCS reduced pain intensity significantly after two weeks of treatment. The attack frequency reduction was not significant. PREP showed an increased N2 latency and decreased peak-to-peak amplitude after anodal tDCS. No severe adverse events were reported.Conclusion
Anodal tDCS over two weeks ameliorates intensity of pain in TN. It may become a valuable treatment option for patients unresponsive to conventional treatment. 相似文献15.
We present a case report of a patient with the typical sensory features of idiopathic trigeminal neuralgia (ITN). The pain was elicited by innocuous stimuli, summated with repeated stimulation, radiated outside the stimulus zone, referred to a distant site, persisted beyond the period of stimulation, and exhibited a variable refractory period. Unusual sensory features included multiple trigger zones that changed over time and involved all 3 trigeminal divisions. Our sensory evaluation indicated that the pain was evoked by repetitive activation of rapidly adapting, A beta, low-threshold mechanoreceptive afferents. However, activation of such mechanoreceptive afferents alone never produces pain in normal situations and often leads to a suppression of pain responsivity. The findings support the idea that the mechanism of pain in ITN involves pathophysiological mechanisms in the central nervous system. Our hypothesis is that structural and functional changes in the trigeminal system result in an alteration in the receptive field organization of wide-dynamic-range (WDR) neurons. There appears to be an alteration in the surround inhibition mechanism of these neurons leading to an expansion of their touch receptive fields. This results in touch stimuli producing activity in WDR neurons that mimics the activity produced under normal conditions by noxious stimuli. Since WDR neurons participate in the encoding of the perceived intensity of noxious stimuli, a series of punctate tactile stimuli are now perceived as localized, pin-prick or electric shock-like sensations. Similar pathophysiological mechanisms may explain, in part, the pain of peripheral neuropathies associated with postherpetic neuralgia, diabetes and causalgia. 相似文献

OBJECTIVE: Pain control in trigeminal neuralgia (TN) is achieved using anticonvulsivants, mainly carbamazepine. When this drug cannot be used, other drugs like gabapentin (GBP) have been used to provide adequate pain control. To improve the therapeutic effect of GBP, we evaluated the clinical efficacy of associating GBP with ropivacain (ROP) analgesic block of facial trigger points in TN patients. DESIGN: Thirty-six TN patients were randomly assigned during 4 weeks to 1 of the following protocols: Protocol I-daily oral GBP administered in a titrated dose; Protocol II-ROP applied as analgesic block to TN trigger points once a week; Protocol III-daily oral GBP plus ROP once a week. Protocol II had to be discontinued in 7/12 patients owing to insufficient pain control. Pain intensity was evaluated by the Visual Analog Scale (VAS) and disability was assessed by Sickness Impact Profile. RESULTS: When compared with Protocol I, Protocol III (GBP+ROP) patients showed (1) a reduction of VAS score after 7 and 28 days of treatment, an effect that was still present 6 and 12 months later; (2) a faster reduction of VAS score using a significantly lower dose of GBP; (3) a smaller total and daily GBP dose at the end of the treatment, which resulted in a total absence of adverse side effects; and (4) an improvement of the functional well-being measured by the Sickness Impact Profile. The number needed to treat (NNT) (GBP+ROP vs. GBP protocols) to obtain 1 GBP+ROP-treated patient with at least 50% pain relief was 1.71 (day 7) and 2.40 (day 28). CONCLUSIONS: The association of GBP and ROP is safe, without side effects and results in an important clinical benefit associated to an improvement of the functional health status of TN patients when compared with GBP alone. This may constitute a therapeutic alternative for pain control in TN patients who cannot be treated with carbamazepine. 相似文献

背景:精神分裂症主要是通过症候学的方法进行诊断,近年来通过神经影像技术与模式识别的结合对精神分裂症患者与正常人进行鉴别的研究已经引起人们的兴趣。
目的:利用模式识别的方法对精神分裂症患者和正常人的大脑前额叶多通道近红外光谱信号数据进行分类鉴别,验证其可行性。
方法:使用言语流畅性测验作为激活任务,采集精神分裂症患者和正常人的大脑前额叶的近红外光谱信号数据。对采集数据进行预处理后计算各通道均值作为特征,计算接收者操作特征的曲线下方面积对通道特征进行分类性能排序,使用支持向量机按性能排序的特征组合做分类,然后用留一验证法计算分类性能指标,验证分类能力。
结果与结论:研究发现特征性能排序前8位的特征组合的准确度最高达到95.24%,并且这8个通道都位于右侧前额叶。推断右侧前额叶区域可能是影响精神分裂症患者的主要脑区,因此根据结果可以推断出近红外光谱数据通过与模式识别方法的结合可以成为辅助诊断精神分裂症病患者的一种手段。 相似文献
