Abstract:
ObjectiveAnalyze preoperative clinical relevanted factors of acute type A aortic dissection with hypoxemia according to a group clinical data.MethodsFrom January 2011 to June 2011,we have collected 54 preoperative cases of acute type A aortic dissection,including 42 males,12 females,aged 28-73 years old,onset to treatment time is 0.4-14.0 days.General information:age,gender,time of onset,body mass index,hypertension,diabetes mellitus,smoking,drinking,heart ejection fraction,prothrombin time,quantitative fibrinogen,fibrinogen degradation products,D-dimer,C-reactive protein,procalcitonin,ICU time,length of hospital stay.According to the blood gas analysis of quiet state case without oxygen,with PaO2 ＜ ( 100-age ×0.33 ±5) mm Hg is for the hypoxemia group,equal or higher than this is no-hypoxemia group.ResultsNo-hypoxemia group has 14 cases,11 males,3 females,average aged (51.14 ± 14.24) years old,including 12 operation patients ( no death) and 2 no-operation patients(2 cases death).Hypoxemia group has 40 cases,31 males,9 females,average aged (50.53 ± 9.73 ) years old,including 33 operation patients(2 cases death) and 7 no-operation patients(7 cases death).There is no significant difference in age,gender,time of onset,hypertension,diabetes mellitus,smoking,drinking,cardiac ejection fraction,prothrombin time and fibrinogen.There is statistically significant on body mass index,fibrinogen degradation products,D-dimer,C-reactive protein,procalcitonin,ICU time and length of hospital stay time ( P ＜ 0.05 ).ConclusionPreoperative hypoxemia with acute type A aortic dissection is associated with obesity,excessive inflammation and activation of coagulation and fibrinclytic system,and hypoxemia may prolong the time of operative patients with acute type A aortic dissection in ICU and hospital.
