  • 前白蛋白、D-二聚体及血小板动态变化评估重症脓毒症患者病情严重度的临床分析

    目的 研究前白蛋白( PA) 、D-二聚体( DD) 及Plt 动态变化与重症脓毒症患者病情严重度及预后的关系。方法 测定198 例重症脓毒症患者入组第1 d、第5 d, 以及出院或死亡前最后一次的PA、DD、Plt、APACHEⅡ 评分, 按预后将患者分为死亡组及存活组, 进行动态观察, 并做APACHEⅡ评分和PA、DD 及PLT 水平动态变化的相关性分析。结果 死亡组与存活组入组第1 dPA、DD 及Plt 比较均无显著差异, 死亡组第5 d 及最后一次DD 水平明显高于存活组( P lt;0. 05) , PA和Plt 明显低于存活组( P lt;0. 01) 。DD 与APACHEⅡ评分呈正相关, PA、Plt 与APACHEⅡ评分呈负相关。结论 DD与脓毒症患者病情严重程度呈正相关, PA 与病情严重程度呈负相关。DD 持续高水平与PA、Plt 持续低水平提示病情危重, 预后不良, 所以联合动态观察PA、DD 和Plt 对判断病情危重度及预后有一定的评估价值。

  • 视网膜中央动脉阻塞患者视力恢复的分析

    目的:评估视网膜中央动脉阻塞后视力的可恢复性。 方法:对发病后视力为无光感、光感、手动和指数的56例60只眼治疗前后视力变化和视网膜循环时间进行了观察。结果:60只眼中视力为无光感者18只眼,丧失视力的时间中位数为4天;光感至指数者42只眼,丧失视力的时间中位数为5天。在经过平均27.8天的观察后,无光感的18只眼中有12只眼的视力增进至光感与0.03之间;光感至指数的42只眼中有40只眼的视力增进至手动至0.7之间。35只眼治疗前后眼底荧光血管造影资料统计表明,10只无光感眼中视网膜循环时间平均缩短(1.5plusmn;1.1)秒(Plt;0.01);光感至指数的25只眼平均缩短(.3土1.0)秒(Plt;0.001)。 结论:视网膜中央动脉阻塞患者已丧失的视力具有一定的可恢复性。 (中华眼底病杂志,1996,12:250-251)

  • Risk Factors for Lower Airway Bacteria Colonization and Ventilator-Associated Pneumonia in Mechanically Ventilated Patients

    Objective To analysis the risk factors for lower airway bacteria colonization and ventilator-associated pneumonia ( VAP) in mechanically ventilated patients. Methods A prospective observational cohort study was conducted in intensive care unit. 78 adult inpatients who underwent mechanical ventilation( MV) through oral endotracheal intubation between June 2007 and May 2010 were recruited. Samples were obtained from tracheobronchial tree immediately after admission to ICU and endotracheal intubation( ETI) , and afterward twice weekly. The patients were divided naturally into three groups according to airway bacterial colonization. Their baseline characteristics, APACHEⅡ score, intubation status and therapeutic interventions, etc. were recorded and analyzed. Results In the total 78 ventilated patients, the incidence of lower airway colonization and VAP was 83. 3% and 23. 1% , respectively. The plasma albumin( ALB) ≤29. 6 g/L( P lt; 0. 05) , intubation attempts gt; 1( P lt; 0. 01) were risk factors for lower airway colonization. In the patients with lower airway colonization, preventive antibiotic treatment, applying glucocorticoid and prealbumin( PA) ≤ 69. 7 mg/L were risk factors for VAP ( P lt; 0. 05) . Conclusions The risk factors for lower airway colonization in ventilated patients were ALB≤29. 6 g/L and intubation attempts gt; 1. And for lower airway colonized patients, PA ≤ 69. 7 mg/L, preventive antibiotic treatment and applying glucocorticoid were risk factors for VAP.
