  • D-二聚体水平测定在肺部疾病中的临床意义

    D-二聚体(D-dimmer)是血浆中交联纤维蛋白经纤溶酶水解所产生的一种特异性终末产物,当机体发生急性肺栓塞、肺癌、慢性阻塞性肺疾病、肺炎、急性呼吸窘迫综合征、慢性支气管炎、支气管哮喘等肺部疾病时会引发体内凝血机制的异常,血液呈高凝状态,继而引发纤溶系统亢进,观察患者的临床症状,积极检测D-二聚体水平的变化,对于疾病的诊断与治疗有着重要的参考价值 。现对近年来有关检测D-二聚体水平与肺部疾病关系的文献进行搜集整理,分析D-二聚体水平测定在肺部疾病的预防、诊断、治疗以及疗效的判断和预后方面的价值。

  • Effects of Bacterial Collagenase on Wound Infection via Blind Means

    【摘要】 目的 探讨细菌性胶原酶对创口感染情况的影响。 方法 2006年11月-2006年12月,对28只新西兰兔分为实验组和对照组,分别予细菌性胶原酶溶液及生理盐水浸润创口并缝合。观察创口感染及局部皮肤的炎性细胞浸润情况。 结果 实验组与对照组创口感染率差别无统计学意(Pgt;0.05),炎性细胞差别无统计学意义(Pgt;0.05)。 结论 细菌性胶原酶在创伤修复过程中不能直接降低感染率,对炎性细胞的迁移并无明显的作用。 【Abstract】 Objective To assess the effects of bacterial collagenase on the wound infection. Methods A total of 28 New Zealand rabbits have chosen from November to December 2006, and were divided into a laboratorial group and a control group. We sutured the wounds and soaked them by the bacterial collagenase liquid or by the physiologic saline solution. The infection and the inflammatory cells of the skin around the wound were observed. Results The difference of the infection rates between the two groups was not statistically significant (P=0.62), nor the difference of inflammatory cells (P=0.84). Conclusions Bacterial collagenase can not decrease the rate of infection directly, and had no obvious effect on the transferring of inflammatory cells.

  • Compare the Ability of Early Warning Score And Modified Early Warning Score to Predict the Mortality of Emergency Admissions

    目的:比较早期预警评分(EWS)和改良早期预警评分(MEWS)预测急诊住院患者死亡风险的能力。方法:随机抽取409名四川大学华西医院急诊住院患者,采用EWS和MEWS对患者进行评分,使用ROC曲线比较两者预测急诊住院患者死亡风险的能力。结果:EWS预测患者住院的曲线面积为0.849±0.132,其最佳截断值为4分;MEWS预测急诊患者住院的曲线下面积为0.876±0.124,其最佳截断值为5分。结论:MEWS较EWS对于预测急诊住院患者死亡风险有较高的效能,还可以进一步改进提高其预测能力。

  • Role of First-aid Fast Track in Triaging Earthquake Trauma Patients

    Objective To elucidate the effect of first-aid fast track in triaging earthquake trauma patients by studying the earthquake trauma patients staying in the Emergency Department of West China Hospital after “5•12 Wenchuan Earthquake” so as to accumulate experience in the treatment of disaster traumas. Methods A retrospective study was done on earthquake trauma patients staying in the Emergency Department of West China Hospital after “5•12 Wenchuan Earthquake” from 14:28 May 12, 2008 to 14:27 May 15, 2008. Differences in care given during the time period were analyzed. Results There were 536 earthquake trauma patients in West China Hospital within 72 hours after the earthquake. Twohundred and seven earthquake trauma patients staying in the Emergency Department had an average stay of 129 minutes during the 24 hours after the quake; 104 earthquake trauma patients staying in the Emergency Department had an average stay of 97 minutes in the second 24 hours; and 226 earthquake trauma patients staying in the Emergency Department had an average stay of 86 minutes in the third 24 hours. Each consecutive day showed shorter average stays. Conclusion The first-aid fast track not only guarantees earthquake trauma patients are saved as soon as possible but also shortens the time in the Emergency Department.

  • The Effect of Earthquake on Emergency Care for Medical and Surgical Critical Patients

    目的:研究地震对非伤员的其他内外科危重患者急诊医疗的影响。方法:采用病例对照研究方法,研究和分析汶川地震发生前后一周急诊科内外科危重患者情况。结果:地震后内外科危重患者数量明显减少,转诊患者和救护车来诊比例降低,但抢救患者比例增加,优化处理流程后急诊诊疗时间明显缩短。结论:虽然地震期间急诊科内外科危重患者总量减少,但存在抢救患者比例增加和院前急救资源减少的问题。应该重视这部分患者的急救医疗需求以及优化处理流程。

  • 对地震挤压伤患者院前急救的反思与研讨

    目的:为挤压伤者的院前急救进行反思和研讨,提出一些新建议,以提高这类伤员的抢救成功率。材料和方法:本文特利用循证医学技术和方法,通过病例分析和文献回顾总结的方式。结果:通过文献回顾和病例分析,地震中挤压伤的院前处理应该注意以下几点:首先是重视早期补液的重要性,特别是液体的类型、量和补碱利尿时机;其次是局部患肢结扎,肢体处理和情绪的稳定;最后伤者获救后切忌盲目转运,现场分拣和急救后再转运。结论:应重视地震伤员院前急救过程中的规范化处理,以期最终改善预后,减少急性肾功衰和脓毒血症的发生,降低病残率和死亡率。
