Objective To find out some possible risk factors of death postcardiac surgery undergoing cardiopulmonary bypass.Method Totally 36 patients,who underwent postcardiotomy undergoing cardiopulmonary bypass in Subei Hospital of Jiangsu Provience from March 2005 to June 2006,were retrospectively analyzed.The criteria for the selection of patients were as follow:(1)patients underwent on-pump cardiopulmonary bypass;(2)patients with heart function in Ⅰ-Ⅲ degree; (3)all patients didn't have organ dysfunction before operation;(4)patients died within 28 days postcardiotomy.Therefore,6 patients who died were admitted as death group,the other 30 patients were admitted as control group.The analysis included: (1)preoperative factors,including gender,age,diagnosis preoperative,NYHA grade,APACHEⅡscore,left ventricular end-diastolic diameter.(2)operative factors:operation time,block aorta time. (3)postoperation factors:hemorrhage volume,mechanical ventilation time,and factors of hemodynamics and oxygen metabolism 6 hour postoperative:heart rate(HR),central venous pressure(CVP),pulmonary arteria wedged pressure(PAWP),cardiac output index(CI),arterial blood lactic acid,partial pressure of oxygen(PaO2),mixed venous oxygen saturation(SvO2),oxygen delivery index(DO2I),oxygen comsume index(VO2I),oxygen extraction ratio (O2ext).Comparisons between two group was made with SPSSl0.0 for windows.Firstly,the data were analyzed with process of single variable analysis and Some parameters,which showed the significant difference,were sorted out from two groups.Then these parameters were put to the IDGISTIC regression analysis.Consequently,the independent risk factors of death of postcardiac surgery could be found.Results The single variable analysis showed that the parameters of APACHE Ⅱ score,left ventricular end-diastolic diameter,block aorta time,mechanical ventilation time,arterial blood lactic acid,SvO2 had significant difference betwen groups(P＜0.05).The LOGISTIC regression showed that left ventricular end-diastolic diameter and arterial blood lactic acid ale the two independent risk factors of death(P＜0.05).Conclusions Arterial lactatemia and left ventricular end-diastolic diameter can be used to predict the prognosis of postcardiotomy undergoing cardiopulmonary bypass.

Objective To evaluate the compliance of sepsis bundles and its impact on the mortality rate in patients with sepsis shock.Methods Fifty-eight adult patients with sepsis shock admitted in the intensive care units from January to December 2007 were enrolled in the study,and the compliance with the 6-h bundle was analyzed.Age,gender,sites of infection,acute physiology and chronic health evaluation II (APACHE II)score,duration of mechanical ventilation,ICU stay and the mortality rate were compared between patients completed 6-h bundles and those not completed 6-h bundles.Results Compliance with the 6-h bundle was obtained in 22 out of 58 patients(37.9%).Patients receiving bundle care had shorter duration of mechanical ventilation and shorter length of ICU stay than non-bundle patients(t=-2.225 and -3.702,P=0.037 and 0.001,respectively),and the mortality rate in 6-h bundle patients was also lower (X2=10.236,P=0.000).Conclusion The application of 6-h bundle care can reduce the mortality rate of the patients with sepsis shock.and the compliance should be improved.

Objective To evaluate the relationship between the extravascular lung water (EVLW) and other markers of lung injury and determine whether or not EVLW predicts survival in patients with acute respiratory distress syndrome (ARDS) and examine if indexing EVLW with predicted body weight (EVLWp) strengthens its discriminative power.Methods EVLW and other markers of lung injury [including:PaO2/FiO2(P/F),oxygenation index (OI) =mean pressure (Pm) × FiO2 × 100/PaO2,static compliance (Cst) and lung injury score (LIS)] were measured prospectively for 3 days in 27 patients with early ARDS between January 2011 and December 2011 at intensive care units (ICU) of Subei People's Hospital.The relationship between indexing EVLW with actual body weight (EVLWa),EVLWp and other markers of lung injury,the 28-day mortality were evaluated.Results Acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ),fluid balance in first 3 days,days of mechanical ventilation and ICU stay were significantly higher on admission in nonsurvivors compared with survivors (P ＜ 0.05).Nonsurvivors had higher OI,LIS,EVLWa and EVLWp than survivors at Days 1 and 3 (P ＜ 0.05).EVLWa and EVLWp were correlated positively with LIS (r =0.471,0.528 P ＜ 0.05) and OI (r =0.527,0.627,P ＜ 0.05) and negatively with P/F (r =-0.467,-0.646,P ＜ 0.05).EVLWp had a stronger correlation to LIS,OI and P/F than did EVLWa.No obvious correlation existed between EVLWa,EVLWp and Cst (r =-0.260,0.226,P ＞ 0.05).ROC curve analysis indicated that EVLWp (0.759,P ＜ 0.05) but not EVLWa (0.661,P＞0.05) discriminated between survivors and nonsurvivors.Three-dav average EVLWp ≥12.5ml/kg predicted the 28-day mortality with 62.5％ specificity and 80％ sensitivity.Conclusion Increased extravascular lung water is a feature of early ARDS and predicts survival.EVLWp,instead of EVLWa,improves the predictive value of extravascular lung water for survival and it is correlated with markers of disease severity.

Objective To evaluate the effects of prone position ventilation (PPV) combined with inhalation of NO on oxygenation of acute respiratory distress syndrome (ARDS) patients.Methods A total of 21 patients with ARDS composed of 15 male and 6 female aged ranging from 2 to 74 years with mean age of 39 ± 17.4 years were hospitalized from September 2008 through January 2011.After application of mechanical ventilation with optimal PEEP,patients still needed the high concentration oxygen inhalation (FiO2 ≥ 60％).They were randomly (random number) divided into three groups for controlled study.Patients of group A were given NO in addition to oxygen inhalation for 4 hours,patients of group B were put in prone position ventilation with oxygen inhalation for 2 hours,then they were returned to the supine position ventilation,and patients of group C were put into prone position ventilation with inhalation of oxygen plus NO for 2 hours,and then they were returned to the supine position ventilation,but they were continued to inhaled NO.The oxygenation indexes of three groups of patients were measured before the intervention,2 hours and 4 hours after the procedure of experiment.Results The oxygenation indexes of three groups of patients were improved in terms of comparison between pre-intervention and 2 hours after intervention,but there was no statistically significant difference found in group A (P ＞ 0.05),the differences in group B and group C were statistically significant (P ＜ 0.05).Compared the oxygen index between pre-intervention and 4 hours after intervention,the differences in group A and group B were not statistically significant (P ＞0.05),but the difference in group C was statistically significant (P ＜ 0.05).Conclusions PPV could improve oxygenation in acute respiratory distress syndrome (ARDS) patients.PPV with NO inhalation could improve oxygenation in acute respiratory distress syndrome (ARDS) patients as well as effectively maintain the oxygenation after patients were returned to the supine position ventilation.Therefore prone position ventilation combined with inhalation of NO improved oxygenation and at the same time reduced the prone position time.

OBJECTIVETo investigate the changes of plasma fibrinogen level among acute ischemic stroke (ACI) subtypes according to Trial of Org10172 in Acute Stroke Treatment (TOAST) criteria and effects of Songling Xuemaikang.

METHODThe 160 patients with acute ischemic stroke were divided into two groups randomly: treatment group 85 cases (Songling Xuemaikang + Shuxuetong + Aspirin enterie coated tablets), control group 75 cases (Shuxuetong + Aspirin enterie ccoated tablets). The plasma fibrinogen was detected before and after treatment.

RESULTCompared with OC subtype, Fbg was higher in LAA, CE and SAO subtypes (P < 0.05). Compared with UE subtype, Fbg was higher in LAA, CE and SAO subtypes (P < 0.05). There was a significantly difference between LAA and SAO (P < 0.05). In LAA, SAO, CE of treatment group,the Fbg level were lowered significantly at the 15th day compared with pretherapy (P < 0.05). There was a significantly difference of Fbg between treatment group and control group In LAA, SAO and CE subtypes at the 15th day (P < 0.05).

CONCLUSIONFbg produces a marked effect at the pathomechanism of LAA, SAO and CE subtypes. Songling Xuemaikang can depress the plasma fibrinogen level of ACI, and be an effective adjunctive therapy on ACI.
