下腹部Joel—Cohen切口术后切口愈合临床观察

目的探讨肥胖患者下腹部手术采用Joel—Cohen切口对预防非感染性切口裂开的临床效果。方法选择切口部位皮下脂肪层厚达4—5cm的妇产科手术患者90例，随机分为观察组44例，采用Joel—Cohen切口；对照组46例，采用下腹正中直切口。观察切口愈合和脂肪液化情况。结果观察组切口甲级愈合率显著高于对照组（P〈0．01）；脂肪液化切口裂开率显著低于对照组（P〈0．05）。结论脂肪组织厚达4—5cm以上下腹部手术切口，采用Joel—Cohen切口可以减少脂肪液化，切口愈合显著优于下腹直切口，值得临床推广应用。     

异位妊娠的腹腔镜手术临床分析

目的探讨电视腹腔镜手术治疗内出血异位妊娠的安全性和可行性。方法回顾分析2000年8月￣2004年8月该院电视腹腔镜手术治疗的15例伴有内出血的异位妊娠(出血量大于800mL,观察组)及同期30例无明显内出血异位妊娠病人的临床资料(对照组)。结果15例病人均手术成功,无中转开腹及并发症发生,两组手术时间及手术后住院时间均无明显差异。结论随着腹腔镜手术操作技巧、麻醉和监护技术的提高,腹腔镜手术治疗内出血甚至休克型异位妊娠在一定条件下是安全可行的。     

Psychiatric patients and their response to experimental stress

Serum levels of Epinephrine (E), norepinephrine (NE), heart rate (HR), skin conductance reaction (SCR) and skin conductance level (SCL) were measured in schizophrenic, endogenous depressed and anxiety patients as well as in normal controls. Conditions were rest, noise and a mental arithmetic (MA) task. Schizophrenic and depressed patients had an attenuated HR response to MA. Moreover, Schizophrenic patients also had higher NE base level and the highest NE secretion during noise. Anxiety and depressed patients showed significantly lower phasic electrodermal activity (SCR) throughout the whole trial, exclusively anxiety patients had significantly higher tonic electrodermal activity (SCL). These findings indicate that autonomous reactions discriminate between patient groups and controls as well as between each other.     

应用预控出血的包皮中远段环形剥除术治疗包皮过长

Objective To investigate the middle and distal circum peeling with bleeding control technique for redundant prepuce. Methods The middle and distal part of prepuce was eireum peeled with bleeding control and electrical scalpel. More preputial inner plate was reserved. Results From January 2004 to July 2008, 51 patients with redundant prepuce were treated with this procedure. The average blood loss was 1 ～2 ml with minimal edema. The proportion of inner and outer plates was suitable. Conclusions This teelmique has the advantages of minimal blood loss and slight edema. The cosmetic result is also satisfactory.     

超声引导下压迫修复冠脉介入术后假性动脉瘤

目的:探讨超声引导下压迫法修复冠脉介入术后假性动脉瘤的可行性和方法。方法:4例冠脉介入术后腹股沟搏动性肿块患者,经彩色多普勒超声确诊股动脉假性动脉瘤,采用实时超声定位及监测下直接压迫法修复股动脉破裂口。结果:3例股动脉假性动脉瘤在超声引导下压迫修复成功,1例失败,未出现并发症。结论:早期超声引导下压迫法结合绷带加压包扎是治疗冠脉介入术后假性动脉瘤的有效方法,简便安全,值得推广。     

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。     

Microanatomy and surgical approaches to the infratemporal fossa: an anaglyphic three-dimensional stereoscopic printing study.

Objective: The infratemporal fossa (ITF) is a continuation of the temporal fossa between the internal surface of the zygoma and the external surface of the temporal bone and greater wing of the sphenoid bone that is sitting deep to the ramus of the mandible. The principal structure to understanding its relationships is the lateral pterygoid muscle. Other important structures are the medial pterygoid muscle, the maxillary artery, the pterygoid venous plexus, the otic ganglion, the chorda tympani nerve and the mandibular nerve. In this study, we describe the microsurgical anatomy of the ITF, as viewed by step-by-step anatomical dissection and also through the perspective of three lateral approaches and one anterior surgical approach. Methods: Eight cadaver specimens were dissected. In one side of all specimens, an anatomical dissection was done in which a wide preauricular incision from the neck on the anterior border of the sternoclidomastoid muscle at the level of the cricoid cartilage to the superior temporal line was made. The flap was displaced anteriorly and the structures of the neck were dissected followed by a zygomatic osteotomy and dissection of the ITF structures. On the other side were the surgical approaches to the ITF. The combined infratemporal and posterior fossa approach was done in two specimens, the subtemporal preauricular infratemporal fossa approach in two, the zygomatic approach in two, and the lateral transantral maxillotomy in two. The anatomical dissections were documented on the three-dimensional (3D) anaglyphic method to produce stereoscopic prints. Results: The lateral pterygoid muscle is one of the principal structures to enable understanding of the relationships into the ITF. The tendon of the temporal muscle inserts in the coronoid process at the ITF. The maxillary artery is the terminal branch of the external carotid artery that originates at the neck of the mandible and runs into the parotid gland. In our dissections the maxillary artery was lateral to the buccal, lingual, and inferior alveolar nerves. We found the second part of the maxillary artery superficial to the lateral pterygoid muscle in all specimens The anterior and posterior branches of the deep temporal artery supply the temporal muscle. In two cases we found a middle deep temporal artery. The different approaches that we used provided different views of the same anatomical landmarks and this provides not only safer surgery but also the best choice to approach the ITF according with the pathology extension. Conclusions: The ITF is a complex region on the skull base that is affected by benign and malignant tumors. The study through different routes is helpful to disclose the relationship among the anatomical structures. Although the authors have shown four approaches, there are a variety of approaches and even a combination of these can be used. This type of anatomical knowledge is essential to choosing the best approach to treat lesions in this area.
