持续靶控输注异丙酚复合硬膜外麻醉用于上腹部手术探讨

目的:评价持续靶控输注异丙酚复合硬膜外阻滞有用于上腹部手术的可行性。方法:30例胃癌手术患者,ASAⅠ～Ⅱ级。随机分成靶控输注异丙酚全麻(T)组15例,靶控异丙酚复合硬膜外阻滞(T+E)组15例。结果:(T+E)组术后躁动、芬太尼、丙泊酚的用量低于(T)组(P<0.05)。异丙酚单位标准化剂量亦较低。两组苏醒时间相似。诱导后两组血压均显著下降(P<0.05),T+E组在诱导后DBP的下降幅度较T组更为显著(P<0.05),T组在探查、术毕、拨管后的SBP、DBP、MAP比(T+E)组显著增高(P<0.05)。两组诱导后至术毕BIS、SEF显著下降,两组间的比较无统计学意义(P>0.05)。结论:靶控输注异丙酚复合硬膜外阻滞用于上腹部手术是可行的,具有异丙酚、芬太尼的用量少、苏醒快、术后躁动少,麻醉深度易于调控,血液动力学较稳定,是一种良好的麻醉方式。     

上前牙倒置阻生拔除后再植的临床体会

为探讨上前牙倒置阻生拔除后再植的可行性，选择上前牙倒置阻生病例15例，经正畸治疗扩展间隙，再经口腔外科手术拔除后再植。结果，86．7％的病例获得良好的治疗效果，无明显松动。认为用拔除后再植术治疗上前牙倒置阻生，能明显改善面形和咀嚼功能，避免了拔牙后再修复。     

颈椎骨折类型与脊髓损伤关系之临床观察

通过对９２例颈椎骨折病例的分析，发现屈曲型损伤最多见（５３％），其次为过伸型（２６％），压缩型（２１％）。屈曲型和压缩型多见于年轻人，而屈曲损伤导致的脱位及过伸型则多见于年龄较大者。爆裂骨折引起的神经损害最重，其次为屈曲型、过伸型及压缩（非爆裂）骨折。神经功能改善率以爆裂型骨折最差，死亡率亦最高，以压缩（非爆裂型）骨折最好，其次为过伸型及屈曲型。文内对各型的特点进行了详细讨论。     

不稳定型下颈椎损伤的手术治疗(附56例分析)

目的分析手术治疗下颈椎不稳定性损伤的适应证、手术方法及疗效。方法2001年1月～2003年1月,手术治疗下颈椎不稳定性损伤共56例。参照Aebi及White等人的手术适应证,以前路手术为主;对于难复性颈椎脱位或不伴椎间盘损伤者,行后路施术或前后联合入路手术;稳定性评分大于8分的前后柱损伤者,行前后联合入路手术。以Frankel评分系统评价神经功能恢复情况,以损伤节段Cobb角及水平移位来评价复位情况,采用Bohlman的X线片标准判定植骨融合情况。结果Frankel评分术前平均为2.3分,术后3.1分;按Bohlman标准3个月时植骨融合率为80%,6个月时为100%。术前Cobb角平均为8°,术后为1.5°,水平移位由术前的平均3.5mm减小到0.5mm。结论手术治疗下颈椎不稳定性损伤具有改善神经功能、恢复颈椎序列、恢复椎间高度及生理曲度、可早日下地活动等优点,手术病例及方法的选择应根据患者是否有致压因素及颈椎稳定性等综合考虑。     

上睑下垂78例手术分析

用额肌悬吊术或提上睑肌缩短术治疗７８例上睑下垂病例，治愈７眼，基本治愈１２眼，矫正不足３眼，矫正过度２眼，笔者认为，术前分析病因；注意提上睑肌肌力的测定；采用适当的手术方法，是手术成功的关键。     

经椎弓根椎间融合与AF治疗胸腰椎骨折

目的：总结32例经椎弓根椎间融合与AF治疗胸腰椎骨折的经验。方法：应用经伤椎椎弓根椎体间融合并AF系统复位内固定，以提高复位效果与脊柱的稳定性。结果：全部病例获随访，时间3～23个月，伤椎均与上位椎体间融合，无矫正角度与高度丢失，无断钉及螺钉松动，神经功能平均1．5级以上的恢复。结论：经椎弓根椎间融合与AF治疗胸腰椎骨折，操作简单，复位可靠，可重建脊柱的稳定性，椎体间融合更符合生物力学内环境的持久稳定。     

Epidemiology of abdominal symptoms in a random population: Prevalence,incidence, and natural history

The study presents results from a five-year follow-up on abdominal symptoms in an age and sex stratified random sample of 4,581 Danes. Abdominal pain occurred significantly more often among women (prevalence: 49%, incidence: 21%) compared to men (prevalence: 38%, incidence: 15%). Five years later the pain had disappeared in 43% of the men and 31% of the women (p=0.003). Distension, borborygmi, and altering consistency of stools occurred with a prevalence of approximately 50% and an incidence of approximately 30%, significantly more often among women compared to men. Five years later these symptoms had disappeared in about 20%. Prevalence of both heartburn and acid regurgitation were significantly higher among men (38%) than women (30%), whereas no sex difference was observed regarding incidence of these symptoms (16%). Approximately 30% of subjects who had experienced heartburn or acid regurgitation did not do so five years later. In conclusion, abdominal symptoms occur frequently and recurrently in the general population. This information is of importance to doctors when they evaluate patients with abdominal complaints, but no obvious organic etiology.     

Intraoperative radiotherapy of upper abdominal tumours

Thirty patients with malignant tumours in the upper abdomen underwent surgery and intraoperalive radiation (IORT), using electron beam, to: the surgical bed, residual or unresected tumour. The technical aspects and results of this treatment are described. Renal, adrenal, bile duct and gastrointestinal tumours were treated. along with several other lesions. The surgical procedure consisted in 10 cases simply of exposure of the tumour for IORT and in 20 the tumour was resected. The TORT dose ranged from 10 to: 20 Gv. In 13 patients, external beam radiation was also given to: residual tumour or to: areas of high risk for recurrence. Chemotherapy was given to: 10 patients. Tolerance to: the combined treatment was acceptable; with few complications related to: IORT.The median follow-up and survival time 23 months (range 4-more than 70 months). Local tumour control rate (or tumour stabilisation) is 90%. Distant metastases developed in 19 patients (63%). The actuarial survival rate for the group projected at 70 months (maximum follow-up) is 37%. IORT in useful in the management of tumours arising in the upper abdominal organs, for palliation surgery or when resectability of the tumour is in doubt. Indications for IORT include patients with uncommon tumours of the upper abdomen who are not be candidates for standardised cancer treatment.Presented at the European Congress of Radiology, Vienna, September 15–20,1991
