目的:探讨腹部急症手术后肺损伤的预防和治疗。方法:回顾性分析40例外科危重病人(APACHEⅡ>8分)首次手术后24小时内的PaO2/FiO2、AaDO2和呼吸频率(BR)与急性肺损伤(ALI)的关系,分为ARDS组( Ⅰ组,12例)和急性肺功能不全组(Ⅱ组,28例),同时分析液体治疗和机械通气模式在防治ARDS中的作用,并计算死亡率。结果: Ⅰ组的PaO2/FiO2、AaDO2、BR和死亡率分别为18.2±4.5kPa、268.7±41.3mmHg、33.7±6.9次/分和41.7%(5/12);Ⅱ组则分别为23.0±5.9kpa、243.8±53.1mmHg、26.9±7.6次/分和3.6%(1/28)。结论:外科危重病人术后24小时内往往伴有不同程度的急性肺损伤,极易发生ARDS;PaO2/FIO2和呼吸频率是早期发现ARDS的临床指标;控制补液量、早期给予激素和尽早加用PEEP(呼气末正压)是防治ARDS的三大重要措施。  相似文献

作者在大鼠失血性休克(4kPa,180分钟)模型上,观察了重组杀菌/通透性增加蛋白(BPI)对肺组织肿瘤坏死因子(TNF)、白介素-6(IL-6)mRNA表达及急性肺损伤的影响,并对肠源性内毒素血症与炎症细胞因子诱发的关系进行了探讨。结果显示:失血性休克可导致血浆内毒素含量显著升高,肺组织TNF、IL-6mRNA表达分别在复苏后2、8小时明显增多(P<0.05~0.01);给予BPI治疗则完全中和休克所致内毒素血症,并不同程度地抑制肺组织TNF、IL-6mRNA的表达(P<0.05~0.01);肺毛细血管通透性与髓过氧化物酶活性均明显降低。作者认为,BPI可有效防止失血性休克诱发的急性肺损伤,其作用机制可能与抑制肠源性内毒素血症所介导的局部组织炎症细胞因子基因表达有关。  相似文献

James Allison Glover served in the Boer War and World War I. In 1917 he was appointed to the Cerebro-spinal Laboratory in London. There, his work on cerebrospinal fever resulted in the "spacing out" of beds in huts and earned him the name of "good friend of the private soldier". In 1919 he proceeded OBE for his work during the war. In 1920 he was appointed medical officer to the new Ministry of Health. He made significant contributions to rheumatology and the understanding and treatment of tonsillitis, and to public health more widely.  相似文献

Anaplastic (undifferentiated) thyroid carcinoma (ATC)   总被引:2,自引:0,他引:2  
BACKGROUND: Old age, reduced general condition and far advanced tumor stage associated with poor prognosis induced the belief that, apart from verifying the diagnosis of anaplastic thyroid carcinoma (ATC) by biopsy, no additional surgery would be justified. However, in some cases, an ultraradical approach was recommended in order to improve the quality of life and survival. METHODS: These are the results of a retrospective analysis involving 120 patients subjected to restricted radical surgery (excising as much as possible of the tumor and local metastases, foregoing ultraradical removal of vital organs such as esophagus, larynx and trachea). RESULTS: Irrespective of the surgical approach used, 6+/-2% of the patients were alive after 5 years (median survival time: 3.1 months). Patients without tumor residues (R0-resections; extending to soft tissue only; Kaplan-Meier estimate - cumulative survival 15+/-5%) had a significantly better prognosis than patients with tumor residues (R1/R2-resections; no patient survived 5 years; P<0.001). Tumor morphology (spindle cells, giant cells, mixed cells) or differentiated parts of the tumor as well as lymph-node involvement had no statistically significant impact on the prognosis. CONCLUSIONS: In ATC, the objective should be to remove as much of the carcinoma as possible (in the ideal case, a thyroidectomy); if lymph nodes are affected, neck dissection should be the goal, if possible (restricted radical approach, improving quality of life). Ultraradical surgery to include segmental resection of larynx, trachea or esophagus do not seem to be indicated, as prolonged survival is questionable and quality of life is certainly diminished.  相似文献

HR-EEG (high resolution EEG) and MEG (magnetoencephalography) allow the recording of cerebral electromagnetic activities with excellent temporal resolution. These tools have also considerably progressed in spatial resolution and now constitute real methods of Electric and Magnetic Source Imaging. Their limits and the precision of the results obtained are discussed in distinct types of partial epilepsy. HR-EEG and MEG allow localization of scalp-EEG interictal spikes and more rarely ictal activities. They now contribute to the presurgical evaluation of pharmacoresistant partial epilepsies. These investigations appear to be of particular importance in presurgical assessment of MRI-negative epilepsy.  相似文献

Phthalocyanines may be an alternative group of macrocycles applicable for use in photodynamic therapy (PDT) of cancer. Although as a class, phthalocyanines localize in tumours, efficacy of cytotoxicity appears to depend to some degree on the specific compound. Biodistribution patterns of the phthalocyanines are similar to those for dihaematoporphyrin ether (DHE); the major sites of deposition being liver, kidney and spleen while the remaining organs show varying degrees of accumulation. The optimal time for PDT when using phthalocyanine appears to be between 24 and 48 h.  相似文献
