The outcome of ganglion clipping in hyperhidrosis and blushing

A total of 114 patients with various sympathetic disorders underwent endoscopic sympathetic block over different thoracic ganglions by the clipping method. The advantages of this method include the recognition of the clipped level, changeability, and reversibility. However, 4.4% of patients were unilaterally clipped at the wrong level.     

颈髓血流障碍与脊髓型颈椎病发病机制的实验研究

目的观察脊髓前动脉阻断对颈髓血供、功能的影响及其病理学变化,研究脊髓型颈椎病的发病机制。方法以家兔为实验模型,阻断C2段脊髓前动脉,在术后6h、24h、72h采用改良Tarlov法对动物行为学评级以及检测运动诱发电位的变化,应用激光多普勒血流测定仪测定颈髓血流灌注量,并观察兔颈髓组织细胞形态学、相关免疫组化的变化。结果术后各时相点神经功能减退,血流量下降明显,神经元骨架结构紊乱,细胞器破坏,出现急性缺血性改变。结论脊髓前动脉血流障碍可导致颈髓缺血性病变,引起脊髓的梗死,是脊髓型颈椎病发生不可忽视的重要因素,对其治疗应注意改善局部血液循环。

目的 评价甲磺酸罗比卡因用于硬膜外阻滞的效应和安全性。方法 45例择期行下腹或下肢手术病人,随机分别接受用甲磺酸罗比卡因(8.94 mg/ml,观察组)或盐酸罗比卡因(7.5mg/ml,对照组)施行的硬膜外阻滞。观察两组在感觉阻滞、运动阻滞、镇痛和肌肉松弛方面的效果,同时观察用药前后肝肾功能变化。结果 观察组和对照组感觉阻滞平面达到T6以上的病例分别为84.3％和76％(P>0.05),Bromage≥3级的病例分别90％和92％(P>0.05)。两组感觉阻滞平面固定时间、Bromage达到最大级别时间、最大级别维持时间和运动阻滞维持时间均无显著性差异(P>0.05)。两组镇痛及肌松满意率无显著性差异。观察组术中2例发生低血压,2例发生心动过缓,而对照组仅1例发生低血压。两组术后24 h天冬氨酸氨基转移酶(AST)、天冬氨酸转氨酶(ALT)、尿素氮(BUN)和肌酐(Cr)均在正常范围。结论 甲磺酸罗比卡因与盐酸罗比卡因行硬膜外阻滞的效应基本相同,且无明显毒性。     

Foley尿管气囊压迫治疗骶前静脉丛大出血的评价(附6例报告)

目的:评价直肠癌根治术中用Foley尿管气囊压迫治疗骶前静脉丛大出血(MPVP)的临床价值。方法:分析1995~2005年用Foley尿管气囊压迫治疗骶前静脉丛大出血6例的临床资料。结果:6例骶前大出血中全部用Foley尿管气囊压迫控制出血,术中出血量为800~1700mL,Foley尿管于术后4d拔除3例,5d1例,6d2例,均无再出血,会阴切口均一期愈合。结论:Foley尿管气囊压迫治疗骶前静脉丛大出血是一种简单安全有效的治疗方法。     

两种不同方法定位肌间沟臂丛神经阻滞的临床观察

目的 观察经肩胛舌骨肌定位和运用神经刺激器定位肌间沟臂丛神经阻滞两种方法的临床效果。方法 选择ASAⅠ-Ⅱ级的择期上肢手术患者60例，随机分为两组：I组（30例）通过肩胛舌骨肌定位穿刺点寻找异感；Ⅱ组（30例）使用神经刺激器定位肌间沟臂丛神经，观察肌肉节律性收缩。两组分别观察进针深度，阻滞效果及不良反应。I组还同时观察肩胛舌骨肌触摸难易度，穿刺部位以及一次异感获得率等。结果 I组肩胛舌骨肌触摸容易者27例（90％），穿刺部位距锁骨上缘1.6-3.1cm，进针深度0.5-1.5cm，一次获得异感26例（87％），阻滞效果完善，无不良反应。Ⅱ组有28例阻滞完善，另2例阻滞不全，2例出现不良反应。结论 运用神经刺激器定位肌间沟臂丛神经阻滞切实可行。而以肩胛舌骨肌定位肌间沟臂丛神经阻滞定位明确，效果满意，简单易行。     

Evaluation of plantar hyperhidrosis in patients undergoing video-assisted thoracoscopic sympathectomy

Background Sympathectomy is the treatment of choice for primary hyperhidrosis. One curious occurrence that is difficult to explain from an anatomophysiological point of view in cases of video-assisted thoracoscopic sympathectomy (VATS) for the treatment of palmar hyperhidrosis (PH) is the observed improvement in plantar hyperhidrosis (PLH). Nevertheless, current reports on VATS rarely describe the effect on PLH or just give superficial data. The aim of this study was to prospectively investigate, how surgery affects PLH in patients with PH and PLH over one-year period. Methods From May 2003 to January 2004, 70 consecutive patients with combined PH and PLH underwent VATS at the T2, T3, or T4 ganglion level (47 women and 23 men, with mean age of 23 years). Results Immediately after the operation, all the patients said they were free from PH episodes, except for two patients (2.8%) who suffered from continued PH. Compensatory hyperhidrosis (CH) of various degrees was observed in 58 (90.6%) patients after one year. Only 13 (20.3%) suffered from severe CH. There was a great initial improvement in PLH in 50% of the cases, followed by progressive regression, such that only 23.4% still presented that improvement after one year. The number of cases without overall improvement increased progressively (from 17.1% to 37.5%) and the numbers with slight improvement remained stable (32.9–39.1%). Of the 24 patients with no improvement after one year, 6 patients graded plantar sweating worse. Conclusion Patients with PH and PLH who undergo VATS to treat their PH present a good initial improvement in PLH that reduces to a lower level of improvement after the one-year period.
