阻滞

Obturator nerve blockalone was of no benefit.

单独闭孔神经阻滞没有益处。

objective:to evaluate junction rhythm and atria pacemaking to show pathway conduction block as successful ablation indicatives applied in avnrt of slow pathway ablation and compare the difference of discharge time and ablation targets to ablation endpoint. methods:153 patients with avnrt were performed slow pathway radiofrequency ablation.

目的：评价以出现交界性心律与心房起搏显示慢径前传导阻滞作为有效消融指标在房室结折返性心动速慢径消融中应用，比较这两种有效消融指标判断方法在慢径消融达到消融终点时的放电时间与消融靶点数的差异性。

It is well established that Cav1.2 encoded L-type calcium channel is prevailing component in cardiac system, while Cav1.3 encoded one dominant expressed in neuron and neuroendocrine cell. However, our and others' previous works have shown that Cav1.3 encoded LTCC was also found in the heart tissues, especially in pacemaking cells of sina atrial node, atrioventricular node and atrium.

最初人们认为心脏中的 L 型钙通道仅包括α1C（Cav1.2），但后来发现α1D（Cav1.3）在心脏中也有表达，并且优势表达于窦房结、房室结和心房，加之发现它在比较低的膜电位（－60~50mv）激活而且α1D基因敲除小鼠表现出窦性心动过缓和房室传导阻滞，所有这些都表明α1D 在维持正常的心脏节律中发挥着至关重要的作用。

Saw palmetto extract contains substances acting as DHT blockers by much of the same mechanism as prostate medicines.

锯棕榈提取物含有的物质作为睾酮阻滞剂的很多相同的机制，作为前列腺药物。

The results revealed that the motor nerves and parasympathetic system would be blocked predicatively by epidural injection with alcohol or phenol glycerin .

硬膜外腔注射无水乙醇和酚甘油进行化学性神经根毁损对实验兔运动神经和植物神经的阻滞效果显著，三月后再次硬膜外腔置管无显著的出血禁忌。

Enflurane combined with thoracic epidural anesthesia can decrease the sympathetic nervous activity,the balance of sympathetic and parasympathetic nervous activity and the total power of sympathetic and parasympathetic ner-vous system significantly;and it can also decrease the influ-ence of operation stimulation on autonomic nervous function and cardiovascular system significantly.

全麻复合胸段硬膜外阻滞可显著降低交感神经活性、交感/迷走均衡性和植物神经总张力；并显著降低手术刺激对自主神经功能及血流动力学的影响，利于机体血流动力学稳定。

There were 15 (11%) technical complications, with the unintentional elicitation of a paresthesia and traumatic needle placement occurring most frequently. A satisfactory block was reported in 136 (98%) patients.

有15（11%）例出现了并发症，主要是无意地导致了感觉过度和穿刺针导致的创伤。136（98%）位病人的阻滞是满意的。

Objective:To compare the clinical effects of brachial plexus nerve block performed with peripheral nerve stimulator or paresthesia technique.

目的：比较外周神经刺激器定位技术与异感定位技术用于锁骨上入路臂丛神经阻滞麻醉的临床效果。

Objective To compare the clinical effects of brachial plexus nerve block performed with peripheral nerve stimulatoror paresthesia technique.

目的 比较外周神经刺激器定位技术与异感定位技术用于锁骨上入路神经阻滞麻醉的临床效果。

Most of nerve blocks are blind puncture, and require preservaion of consciousness and cooperation so that patients can tell paresthesia and the site of its radiations.

神经阻滞多为盲探性操作，要求病人清醒合作能说出异感并能辨别异感放射的部位。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
