液相连续反应釜反应效果预测

液相连续反应釜反应效果可如下进行预测。通过实验室装置测定并绘制拟定条件下的反应动力学曲线。把生产釜模拟为带死角和短路的理想釜,用水作介质在生产釜中进行流动模型试验,测量一系列停留时间分布密度函数,得到两个模型参数,并建立操作线方程。反应动力学曲线和操作线的交点为此液相连续反应釜的预测结果。

目的：探讨内镜下低温等离子治疗舌甲状舌管囊肿的手术方法、疗效和适应证。方法：对11例舌甲状舌管囊肿患者行内镜下低温等离子舌甲状舌管囊肿切除术,观察疗效及并发症情况。结果：1l例患者术后症状改善,无严重并发症发生,随访1-3年,无复发。结论：内镜下低温等离子治疗舌甲状舌管囊肿手术时间短,术中出血少,术后反应轻、恢复快,疗效满意。     

经尿道前列腺模块化剜除术教学体会

探索建立一种适合经尿道前列腺微创剜除术的新手术模式和教学方法,以降低手术难度,缩短术者学习曲线。按照手术操作顺序、路径将前列腺剜除术拆分为A、B、C、D四个不同的模块,将此手术模式命名为“经尿道前列腺模块化剜除术”。该手术模式优化了操作过程的设计,将手术操作内容模块化、流程化,降低了操作的难度,简化了手术步骤,可有效缩短手术时间并方便初学者开展并掌握这一术式,有一定推广价值。     

腹腔镜与开腹手术治疗良性卵巢囊肿的疗效分析

目的:探讨腹腔镜手术治疗卵巢囊肿的临床应用价值。方法:回顾分析2007年1月至2008年1月在我院分别接受腹腔镜与开腹手术治疗卵巢囊肿的患者各32例。结果:腹腔镜组切口明显小于开腹组,术中出血量、手术时间明显少于开腹组,两组比较差异均具有统计学意义(P<0.001);腹腔镜组患者术后镇痛药物使用人数明显少于开腹组(P<0.001),术后肠蠕动恢复时间、住院天数明显短于开腹组(P<0.001),术后工作恢复时间、术后病率明显优于开腹组(P<0.05)。结论:腹腔镜下卵巢囊肿手术安全有效,具有创伤小、术后恢复快、住院时间短及术后病率低等特点。     

Kiwi Omnicup versus Malmstrom metal cup in vacuum assisted delivery: a randomized comparative trial

AIM: To compare the success, clinical outcomes, and maternal and neonatal complications between the Kiwi Omnicup and the Malmstrom metal cup in vacuum assisted delivery. METHODS: This was a prospective randomized comparative trial. Women who required vacuum assisted vaginal delivery were randomized into the Kiwi Omnicup (KO) group and the Malmstrom metal cup (MM) group. The vacuum assisted deliveries were conducted according to hospital protocol. Details of the procedure and delivery outcomes including success and complications were analyzed. RESULTS: One hundred and sixty-four women were recruited - 85 were assigned to vacuum assisted delivery using the KO and 79 the MM. One hundred percent delivery success was achieved with no significant differences between the two instruments in terms of maternal morbidity (P = 0.66). Six women in the MM group sustained post delivery complications in comparison to five in the KO group. Three babies were diagnosed with birth asphyxia in each group. More babies in the MM group were admitted to the Neonatal Intensive Care Unit (NICU) (10 babies versus 5 babies) and suffered complications (14 versus 12 babies), compared to the KO group, although the difference was not statistically significant. There were no intrapartum or neonatal deaths and of those admitted to the NICU, all were discharged within a week without any serious consequences. CONCLUSION: Kiwi Omnicup is an effective alternative to the currently available Malmstrom metal cup for vacuum assisted delivery with no increase in maternal or neonatal morbidity or mortality.
