Objective To investigate the prethrombotic state and effect of anticoagulation therapy in patients with chronic obstructive pulmonary disease(COPD) and ventilator-associated pneumonia (VAP)．Methods Forty-six COPD patients were divided into VAP group(25 cases)and non-VAP group (21 cases)．The VAP group were randomly subdivided into two groups：group A(conventional therapy group，n=13)，group B(conventional therapy+anticoagulation therapy group，n=12)．The D-dimer (DD)，fibfinogen(FIB)，pulmonary artery pressure(PAP)and the time of weaning were compared between these groups．Results In the COPD patients，the levels of DD，FIB and PAP were significantly increased in VAP group compared with non-VAP group[(0．50±0．26)mg／L，(3．67 ±0．88) L，(31．71 ± 5．66)mm Hg vs(0．23±0．12)mg／L，(1．56±0．45) L，(15．28 ±2．84)mm Hg，respectively，all Plt; 0．05]．In the COPD patients with VAP，the levels of DD，the content of FIB，PAP and mortality were significantly lower in group B with shorter time of weaning compared with group A[(0．22±0．16)mg／L， (1．56±1．17)g／L，(16．00±2．48)him Hg，8．33％ and(4．00±1．41)d vs(O／41±0．09)mg／L，(3．66± 1．03) L，(28．00±0．85)mm Hg，15．4％ and(10．76±3．35)d，respectively，all Plt;0．05]． Conclusions Prethrombotic state exists in COPD patients with VAP．Aggressive anticoagulation on base of routine therapy，by ameliorating microcireulation，call shorten the time of weaning and reduce the mortalit in these patient
【摘要】目的探討鼓膜置管對鼻咽癌(NPC)患者放療前后分泌性中耳炎(SOM)的療效。方法2005年3月2010年1月將60例(84耳)NPC并發SOM患者分為兩組:A組30例行鼓膜切開鼓膜置管;B組30例保守治療為對照組,并行隨訪,對兩組患者有效率和并發癥發生率進行統計。結果60例中58例存活,1例死于全身衰竭,1例死于大出血。存活患者中治療SOM有效率為:A組85.4%(35/41),B組為30.2%(13/43),兩組差異有統計學意義(Plt;0.05);并發癥發生率A組為14.6%(6/41),B組為69.8%(30/43),B組并發癥高于A組,差異有統計學意義(Plt;0.05)。結論NPC患者在放療后,咽鼓管功能受到嚴重損害,是不可逆的病變,鼓膜置管治療NPC并發SOM較保守治療效果好,并發癥的發生率低。
