局部麻醉下经电视胸腔镜和小切口开胸诊治胸膜、肺部疾病

目的探讨局部麻醉下经电视胸腔镜和胸部小切口诊治胸膜、肺部疾病的可行性。方法自2002年2月至2005年3月,对30例胸膜、肺疾病患者施行局部麻醉下开胸手术。按手术方法的不同将患者分为两组,小切口开胸组:16例,在局部麻醉下采用胸部小切口在开放性气胸状态下对增厚的胸膜和弥漫性肺疾病进行活组织检查;电视胸腔镜组:14例,在局部麻醉下经胸腔镜在闭合性气胸状态下诊治恶性胸水、复发性气胸等。结果小切口开胸组中行胸膜活检13例,其中10例为恶性肿瘤胸膜转移、胸膜淀粉样变1例、胸膜纤维增生样改变2例;弥漫性肺疾病活检3例,3例中肺间质性纤维化2例、型肺结核1例。电视胸腔镜组14例中,除1例因发现胸腔内有致密粘连而转行全身麻醉下开胸手术外,其余13例均在局部麻醉下完成胸膜活检,复发性气胸肺大泡切除,顽固性胸水的胸膜固定术;电视胸腔镜组中用胸腔镜辅助诊断为恶性胸水4例,肝性胸水1例;胸腔镜辅助治疗10例,其中顽固性(含肝性胸水)胸水行胸膜固定术8例,复发性气胸行肺大泡切除和胸膜固定术2例。两组患者均无手术并发症和死亡。结论局部麻醉下经胸腔镜及胸部小切口能够完成胸膜、肺疾病活检术及简单的手术。该方法经济、微创、对麻醉要求低,有利于临床普遍开展。     

全麻复合硬膜外阻滞与单纯全麻的比较

比较全麻复合硬膜外阻滞和单纯全麻在围术期对机体应激、炎性、免疫等方面的影响。使用全麻加硬膜外麻醉能有效地抑制手术引起的应激反应，稳定循环状态，减少并发症，使病人在术中更为安全平稳，麻醉效果更为可靠，术毕清醒快，术后镇痛有利于术后病人咳嗽咯痰，并且能减轻围手术期对T细胞亚群的影响。     

Peripheral Foot Blockade Versus Popliteal Fossa Nerve Block: A Prospective Randomized Trial in 51 Patients

The majority of foot and ankle operations are performed on an outpatient basis and often under some form of regional anesthesia. In this prospective, randomized study of 51 patients undergoing elective unilateral forefoot procedures, we compared 2 different anesthetic techniques: the peripheral foot blockade and the popliteal sciatic nerve block. Variables assessed included the quality of surgical anesthesia, postoperative analgesia, and the incidence of postoperative complications. The anesthesia was classified as effective if it was the sole anesthetic technique for the forefoot surgery. We found successful results in both groups: 92% in the foot block group and 96% in the popliteal block group. Analysis of time required to perform the anesthetic procedure showed a significant difference between the 2 groups, with foot block being considerably faster (14.3 minutes vs 19.2 minutes for popliteal block) (P = .0078). Foot block patients demonstrated 10.96 hours of analgesia, whereas popliteal block patients exhibited 14.32 hours (P = .132). With a mean follow-up of 5.7 months, we did not find anesthesia-related complications in any of the patients. Both techniques showed a high level of safety and efficacy, with no significant difference detected between them. Our patients showed a high rate of satisfaction with both procedures (96% for foot block patients and 96.1% for popliteal block patients) and reported a good discharge disposition. These data show that both procedures are safe and effective anesthetic techniques and well suited to forefoot ambulatory surgery.     

不同麻醉方式对儿童腹腔镜疝囊高位结扎术应激反应的影响

目的探讨两种麻醉方法对儿童腹腔镜疝高位结扎术（lapamscopic hernia sac high ligation）应激反应的影响。方法ASAⅠ-Ⅱ级择期行腹股疝疝囊高位结扎术患儿60例，年龄6—12岁，随机分为硬膜外麻醉组（E组）和单纯气管内全麻组（G组）各30例。检测术中不同时点血浆皮质醇（Cor）、去甲肾上腺素（NE）、肾上腺素（E）、促肾上腺皮质激素（ACTH）浓度并观察平均动脉压（MAP）和心率（HR）的变化。结果E组各时点Cor、NE、E、ACHT浓度无明显变化（P〉0．05），G组气腹后上述各指标较气腹前明显增高（P〈0．05）且显著高于E组同时点（P〈0．05）（见表2）；E组气腹后平均动脉压及心率变化无统计学意义（P〉0．05），而G组的则显著升高（P〈0．05）；两组患儿气腹10min后PaC02均显著增加（P〈0．05），停气腹后渐恢复至正常，血PH值则变化不明显。结论硬膜外麻醉复合基础麻醉相对于单纯气管内全麻更能有效抑制儿童腹股疝疝囊高位结扎术的应激反应。     

丙泊酚、硫喷妥钠联合麻醉诱导对血液动力学的影响

目的：观察小剂量丙泊酚和硫喷妥钠联合用于麻醉诱导对血流动力学的影响及临床应用价值。方法：择期全身麻醉气管插管手术患者84例，ASAⅠ-Ⅱ级，随机分成3组（n=28），硫喷妥钠组（A组）：诱导量5mg/kg；丙泊酚组（B组）；诱导量2.0mg/kg；联合诱导组（C组）硫喷妥钠1－2mg/kg加丙泊酚0.5-1.0mg/kg，观察诱导后2min,5min,10min血液动力学变化。结果：C组在丙泊酚诱导前先静脉预注硫喷妥钠1－2mg/kg，患者静脉注射部位疼痛发生率明显低于B组（P＜0．01），平均动脉压和心率均无明显变化（P＞0．05），而A和B组给药后2min与5min平均动脉压均低于麻醉前，心率均高于麻醉前（P＜0．05－P＜0．05）。结论：丙泊酚与硫喷妥钠联合麻醉诱导具有协同作用，减少单独用药不良反应发生率，血液动力学稳定，麻醉诱导更加平稳，安全，为临床全麻诱导提供一种可行的方法。     

A comparative study on therapeutic method of traumatic epidural hematoma

Objective： To explore the therapeutic methods, surgical indications and clinical practice of minimally invasive surgery on traumatic epidural hematoma （EDH）. Methods： Retrospective study was made on 135 patients with traumatic EDH admitted into our hospital from June 2002 to August 2005.

The mean time of operation, average days in hospital, expenditure and prognosis of two groups were recorded and analyzed. Results： There was no significant difference in therapeutic efficacy between two groups. Patients in treatment group had a shorter hospital stay and less expenditure than those in control group. Conclusion： Mini-invasive negative pressure drainage is simple, effective, economical and applicable to some traumatic EDH patients.
