Malignant peripheral nerve sheath tumors arising from cranial nerves or their branches are very uncommon.

从颅神经及其分支发生的恶性外周神经鞘膜瘤非常少见。

Objective: To investigate the effect of obturator nerve blockade guided by peripheral nerve stimulator combined with lower epidural blockade in patients with bladder tumor adjacent to the ureteral orifice.

目的：观察神经刺激仪引导定位闭孔神经阻滞复合低位硬膜外麻醉用于输尿管开口周围的膀胱肿瘤患者经尿道膀胱肿瘤电切术的麻醉效果。

Is different according to the condition,the LDH nerve hinders the treatment to include:The intervertebral hole nerve root hinders,the sacral canal to hinder and outside the sacral canal large dose drop note therapy,the hard membrane and the leaving alone drive pipe hinders,the partial pain spot continuously hinders,the side recessus to hinder,in the intervertebral disc to hinder.

根据病情不同，LDH的神经阻滞治疗有：椎间孔神经根阻滞、骶管阻滞及骶管大剂量滴注疗法、硬膜外及留置导管连续阻滞、局部痛点阻滞、侧隐窝阻滞、椎间盘内阻滞。

Methods A total of 30 patients receiving open cholecystectomy under the general anesthesia and epidural anesthesia in our hospital were selected.The right internal jugular vein and femoral vein catheterization was performed after the anesthesia induction and intubation to continuously monitor CVP and the inferior vena cava pressure.Meanwhile, the changes in CVP, MAP, HR, IVCP before abdominal opening,upon pulling gallblad-der as well as 5 min, 10 min and 15 minutes after the opening of deep retractors were observed, recor-ded and compared.

选择在全麻加硬膜外麻醉下开腹胆囊切除手术病人30例，麻醉诱导插管后行右颈内静脉和股静脉穿刺置管，连续监测CVP和下腔静脉压，观察并记录开腹前、牵拉胆囊时、深部拉钩牵开后5、10、15 min及关腹后CVP、MAP、HR、IVCP的变化，并进行显著性检验。

BACKGROUND: Prewarming and intraoperative warming with forced air-warming systems prevent perioperative hypothermia and shivering in patients undergoing elective cesarean delivery with epidural anesthesia.

背景：术前和术中使用充气式保温系统能预防硬膜外麻醉行择期剖宫产术患者的围术期低温及寒战。

Objective To evaluate the superiority of neuro-physiological prefading, which was achieved to promote the homeostasis of organisms in CSEA dur on aged patients.

目的：探讨预防性调节高龄患者神经体液系统，提高在脊麻-硬膜外联合麻醉下机体内环境稳定性。

Application of neuro-physiological prefading in CSEA during transurethral vaporization of the prostate on aged patients had a lot of advantages. The security was more reliable. It had little influence on patients. It was the optimal method of anesthesia.

神经生理预调节在高龄患者前列腺电切术脊麻-硬膜外联合麻醉中的应用增加了机体稳定性，生理影响小，提升了CSEA在高龄患者中应用安全性。

Methods: Sixty patients in epidural anesthesia of gynecological surgery were randomly divided into two groups(n=30). Group A midazolam 0.04 mg/kg and fentanyl 1.0 μg/kg; group B: pethidine 1.0 mg/kg and haloperidol 0.05 mg/kg.

选择ASA 1~2级硬膜外麻醉下行妇科手术患者60例，随机分成两组，每组30例。A组：咪唑安定0.04mg/kg+芬太尼1.0μg/kg；B组：哌替啶1.0mg/kg+氟哌利多0.05mg/kg。

For different configuration of the distributor,the flows of R134a outside the horizontal tube under different working conditions were simulated and calculated.

降膜式蒸发器是利用制冷剂管外蒸发达到与管内工质换热的目的，即冷媒介质在蒸发管内流动，与蒸发管外流过的制冷剂液体进行换热，使其蒸发，实现热量的传递。

The difference of the characteristics of HHQ monolayer is dependent on the difference of radii,nuclear charges and the structures of valence shell of metal ions.

金属离子的半径、电荷及核外价电子层结构不同是影响HHQLang－muir单分子层膜性能的本质原因。
