Spigelian hernias: a prospective analysis of baseline parameters and surgical outcome of 34 consecutive patients

Most of the papers published on spigelian hernia are either case reports or small retrospective series. In this prospective multicenter study, we aimed to outline the specific features of spigelian hernias and patients’ characteristics more clearly. Surgeons enrolled patients to be entered into the database as they diagnosed and treated the hernias at will. The baseline and surgical outcome parameters were noted in each patient. A painful mass was the main presenting complaint in half of 34 patients. Accurate preoperative diagnosis was possible in 31 patients. Open intraperitoneal mesh repair was the preferred technique. The mean hospital stay and time until return to normal daily activities were 4.1 and 15.6 days. Although a rare condition, diagnosis of a spigelian hernia is not difficult once remembered. Its surgical repair seems to cause few complications and is very well tolerated by the patient.     

吸入麻醉药作用机制的5埃理论

在过去的20多年中，对吸入麻醉药作用机制的合理解释大量增多，同时也提出了更多目前还不能回答的问题。Eger等提出了吸入麻醉药产生对伤害性刺激无体动反应的作用靶位可能是两个相距5埃的位点的假设，简称5埃理论。现就相关问题作一综述。     

硬膜外穿刺针外套管在腹腔镜小儿斜疝高位结扎术中的应用

目的探讨硬膜外穿刺针外套管在腹腔镜小儿斜疝疝囊高位结扎中的应用价值。方法2003年4月-2006年5月,我院对230例小儿斜疝手术应用硬膜外穿刺针外套管代替雪橇钩针实施腹腔镜疝内环口荷包高位结扎术。结果230例手术均获得成功,手术时间：单侧161例8-10 min,嵌顿疝39例15-20 min,双侧30例16-20 min;术后未见有阴囊水肿及睾血疼痛及缺血坏死。术后随访2-6个月111例,6-12个月52例,12-24个月37例,24-36个月30例,无复发。结论硬膜外刺针外套管可替代小儿疝囊结扎专用的雪橇钩针,简便,经济,适合在所有基层医院推广。     

瑞芬太尼对老年患者麻醉诱导时血流动力学的影响

［摘要］目的观察瑞芬太尼全麻诱导对老年患者血流动力学的影响。方法60例ASAⅠ～Ⅱ级老年患者随机分成3组，F组、R1组和R2组，每组20例。F组静脉诱导用药：咪达唑仑0.05 mg·kg-1，芬太尼3 μg·kg-1，丙泊酚1 mg·kg-1，待入睡后注入维库溴铵0.1 mg·kg-1气管插管；R1组用瑞芬太尼1 μg·kg-1代替芬太尼；R2组用瑞芬太尼1.5 μg·kg-1代替芬太尼。观察诱导时血压、心率的变化，同时记录使用阿托品和麻黄碱情况。结果R2组最低血压（MAP1 ）、最高血压（MAP2）明显低于其他两组(P＜0.05＝； R2组 最低心率（HR1）、最高心率（HR2）明显低于F组(P＜0.05＝。结论瑞芬太尼可以用于老年患者的全麻诱导，但在诱导时要密切注意血流动力学变化。

目的研究氯胺酮在大鼠肝移植中的合适剂量.方法对100只雄性Wister大鼠行40例肝移植,观察供受体麻醉过程、药物剂量和效果. 结果供体手术氯胺酮麻醉的剂量以100～125 mg/kg合适,受体手术氯胺酮麻醉的剂量以75～100 mg/kg合适.结论在大鼠肝移植的手术中,氯胺酮是一种理想的麻醉药品.     

腰麻硬膜外联合麻醉在全产程中的镇痛效果及对母婴的影响

①目的　探讨腰麻硬膜外联合麻醉在全产程中的镇痛效果以及对母婴的影响。②方法　选择ASAⅠ～Ⅱ级、无禁忌证的单胎头位临产初产妇 30 0例 ,随机分为腰硬组 (腰麻硬膜外联合麻醉 )、硬外组 (硬膜外麻醉 )和对照组 (未用任何麻醉方法 )各 10 0例。行L2～ 3 椎间隙一点穿刺并一次成功。分别观察镇痛效果、起效时间、用药量、副作用、产程、分娩方式及母婴情况。③结果　腰硬组镇痛效果、起效时间以及用药量明显优于硬外组(uc=5 .34,t=16 .92～ 2 9.6 9,P <0 .0 1) ;与对照组比较 ,宫颈扩张加速 ,第一产程明显缩短 ,而第二产程延长 (t =3.34～ 4 8.4 9,P <0 .0 1) ,剖宫产率明显下降 ,而阴道助产率增高 ,胎儿宫内窘迫的发生率下降 (χ2 =6 .82～ 2 0 .35 ,P <0 .0 1)。④结论　腰麻硬膜外联合麻醉用于分娩镇痛优于硬膜外麻醉 ,是一种安全有效、更适合全产程镇痛的麻醉方法。     

The Application of Topical Anesthesia Combined with Subconjunctival Anesthesia for Glaucoma Surgery

Purpose: To evaluate the feasibility, reliability and analgesia effect of topical anesthesia combined with subconjunctival anesthesia in anti-glaucomatous surgery.Methods: Two hundred and four cases (357 eyes) underwent anti-glaucomatous surgeries under topical anesthesia with 0.5％ Alcaine eye drops combined with subconjunctival anesthesia with 2％ Lidocaine. The analgesic effect was analysed with visual analogue pain scale.Results: Among all of 357 eyes, 62 eyes underwent peripheral iridectomy, 67 eyes underwent simple trabeculectomy, 167 eyes underwent compound brabeculectomy and 12 eyes nonpenetrating trabecular surgery. The effects of anesthesia were as follows: 304 eyes (85.2％) were painless (Grade Ⅰ), 50 eyes (14.0％) were slight painful (Grade Ⅱ), and 3 eyes (0.8％) were more painful (Grade Ⅲ) during surgery. And no severe complications were observed in all the cases during surgery and postoperatively. Amaurosis fugax was not observed in the glaucoma patients at the late stage with narrow vi

气管内硬膜外联合麻醉下的超前镇痛

目的研究气管内硬膜外联合麻醉下,硬膜外给药时间不同、全麻诱导药物不同对术后镇痛产生的影响。方法开腹行切除肝癌、胃癌的病人120例,随机分为A、B、C、D4组,每组30例。A组:在T8-9经硬膜外注入1%利多卡因和0.25%布比卡因混合液6～8ml,再经硬膜外注入含吗啡2mg、氟哌利多2.5mg的生理盐水10ml;全身麻醉诱导药物为芬太尼3μg·kg-1,异丙酚1～1.5mg·kg-1,琥珀胆碱2mg·kg-1。B组:诱导药物中不使用芬太尼,用利多卡因1～1.5mg·kg-1代替,术中也不使用芬太尼,其余条件同A组。C组:在T8-9行硬膜外穿刺,之后行全身麻醉诱导,诱导药物为芬太尼3μg·kg-1,异丙酚2～2.5mg·kg-1,琥珀胆碱2mg·kg-1,必要时可加芬太尼2～3μg·kg-1。切皮后90min,经硬膜外注入1%利多卡因和0.25%布比卡因6～8ml,再经硬膜外注入含吗啡2mg、氟哌利多2.5mg的生理盐水10ml。D组:诱导药物中不使用芬太尼,用利多卡因1～1.5mg·kg-1代替,术中也不使用芬太尼,其余条件同C组。分别于术毕后4、8、24、48h观测VAS、镇痛药消耗量、恶心、呕吐、骚痒等指标。结果A组的药物消耗量最少、镇痛效果最好;B组和C组次之;D组的药物消耗量最大,镇痛效果最差。结论硬膜外复合气管内麻醉时,硬膜外麻醉与芬太尼同时使用,术后镇痛效果最好。
