目的 探讨前列地尔对肺心病并发多脏器衰竭(MOF)的疗效。方法 对70例患者随机分为A组40例(观察组)，选用前列地尔注射液10～20μg，另给氨茶碱0．25～0．5g，加50％葡萄糖液20～40ml静注，1／d疗程2W。B组不予前列地尔治疗，其余治疗同A组。观察血气(PO、PCO2)、BUN、Cr、CI、EF、神志、呕血、便血、基础情况治疗后A、B两组的变化。结果 A组的显效率及有效率明显高于B组(P＜0．01)，基础情况治疗后A组疗效叫显优于B组(P＜0.01)，但B组间比较无明显改变(P＞0．05)。结论 前列地尔与氨茶碱合用对肺心病并发多脏器衰竭的疗效显著优于单独使用氨茶碱。     

氟乙酰胺中毒致多脏器功能衰竭45例报告

氟乙酰胺是一种高效、剧毒、内吸收性强的有机氟杀虫剂，农村常用来浸渍食物以诱杀灭鼠，如果被人误食，或者自杀时服用，可引起中毒。从1996年至2001年作者共抢救本院收治的氟乙酰胺中毒并多脏器功能衰竭(MOF)病人45例。现报道如下。     

Immunologie bei Schwerverletzten

Zusammenfassung. Der klinische Verlauf bei polytraumatisierten Patienten wird durch das h?ufige Auftreten schwerwiegender immunologischer Komplikationen beeintr?chtigt. Die Immunantwort auf schweres Trauma kann durch die vermehrte Freisetzung proinflammatorischer Mediatoren über das „systemic inflammatory response syndrome (SIRS)“ zum Mehrorganversagen [„multisystem organ failure (MOF)“] führen, welches mit einer Letalit?t von bis zu 80 % behaftet ist. Charakteristisch für die Entwicklung des Multiorganversagens ist das Auftreten des „remote organ failure (ROF)“, eine Fehlfunktion von Organen, die durch das eigentliche Trauma keinen direkten Schaden erlitten haben. Diese Arbeit gibt einen kurzen überblick über die neueren Entwicklungen auf dem Gebiet der tierexperimentell-immunologischen Traumaforschung und geht eingehend auf den aktuellen Stand der klinisch-immunologischen Traumaforschung ein. Insbesondere wird die Bedeutung der sog. pro- und antiinflammatorischen Cytokine bei der Entstehung von SIRS, MOF und ROF er?rtert. Trotz der vielen Fortschritte auf dem Gebiet der klinischen Immunologie und der vielf?ltigen Informationen über die Trauma-induzierten Immunfunktionsst?rungen müssen jedoch noch viele offene Fragen gel?st werden, bevor die immunologischen Ver?nderungen nach schwerem Trauma durch immunmodulatorische Therapieans?tze nachhaltig positiv beeinflu?t werden k?nnen.      

多器官衰竭代谢支持的实验研究

本实验对腹腔感染造成多器官衰竭的动物观察了不同全静脉营养配方在代谢支持中的作用。结果显示:在兔感染性多器官衰竭早期,实行代谢支持能够不同程度地增加体重、促进蛋白质合成和扭转负氮平衡。适当减低糖供给的非蛋白热量可以减轻应激反应,增加氮保留和改善肺功能。供给氨基酸过多则增加应激反应、增加尿氮排出和加重呼吸负担。     

多器官功能衰竭患儿血糖血乳酸血渗透压的改变

对５０例ＭＯＦ患儿血糖血乳酸血渗透压进行了检测，并与３５名健康儿童进行比较。结果显示危重患儿血糖血乳酸明显高于对照组，血糖血乳酸呈正相关，提示高血糖是危重患儿应激状态下的主要代谢改变。当患儿血糖＞１５ｍｍｏｌ／Ｌ血乳酸）５ｍｍｏｌ／Ｌ时，其死亡率明显增加，因此血糖血乳酸的变化可作为ＰＩＣＵ的常规监测指标。     

Damage control orthopaedics in polytraumatized patients- current concepts

The principles of fracture management in patients with multiple injuries continue to be of crucial importance. Early treatment of unstable polytraumatized patients with head, chest, abdomen or pelvic injuries, with blood loss followed by immediate fracture fixation (Early Total Care -ETC) may be associated with secondary life threatening posttraumatic systemic inflammatory response syndrome (SIRS). Development of SIRS is typically a function of the type and severity of the initial injury (the “first hit”). Immediate Fracture fixation, using reamed nails or plates, in such unstable patients with multiple injuries is subsequently defined as the “second hit” and may be associated with development of acute respiratory distress syndrome (ARDS) and multiple organ failure (MOF), with relatively high morbidity and mortality.The other alternative for long bone fracture fixation in unstable polytraumatized patients is based on immediate treatment of life threatening conditions related to the injuries, followed by the initial use of minimally invasive modular external frames for long bone fractures and is called Damage Control Orthopedics (DCO) and is widely accepted. In order to refine the DCO concept and to avoid an overuse of external fixation, the “Safe Definitive Surgery” (SDS) concept has been introduced, which is a dynamic synthesis of both strategies (ETC and DCO). The SDS strategy employs clinical parameters and includes repeated assessment of patients. The following paper is going to summarize historical backgrounds and recent concepts in treatment of polytraumatized patients.

MEMSurgery: an integrated test-bed for vascular surgery

Many surgical procedures require skillful manipulations of blood vessels, especially in conventional invasive or minimally invasive surgical procedures. Current surgical methods do not allow the surgeon to receive any real time feedback of the tissue properties when operating on the vessel. As a result, the unintentional application of excessive force may damage the blood vessel. To minimize such trauma, and to study the interaction of surgical instruments with the vessel structure, we have developed an integrated surgical testbed called MEMSurgery (Microelectromechanical Sensory augmented Surgery). The test-bed integrates four elements: a) force sensors mounted on surgical appliances, b) a feedback control mechanism utilizing the intrinsic mechanical properties of the blood vessel, c) feedback of the force applied on the tissue back to the surgeon through a haptic feedback device, and d) visual feedback by a graphical computer model of the vessel. Finally, we evaluate the performance of MEMSurgery by testing the hypothesis that the combination of haptic feedback, feedback control based on vascular mechanical properties, and real-time visual representation of the vessel will help the surgeon decrease the probability of applying excess force while occluding the blood vessel. To this end, we designed a rodent experimental model to obtain the ideal minimum occlusion force (MOF). After a series of human performance studies, and subsequent comparison to direct application of force on the forceps (without feedback), the results show that the probability of applying reasonable MOF increases from 35.5% to 80%. After a brief training period, the probability increases to 90%.
