RESUMEN
Objective To evaluate timing of tracheal intubation impact on the therapeutic effect of acute severe organophosphate poisoning( ASOPP) patients. Methods Retrospectively analyze 82 ASOPP patients with respiratory failure ( RF). The patients were divided into timely tracheal intubation group(n = 42) and delay tracheal intubation group (n =40) ,and compare the therapeutic effect of these two groups. Results Compared with timely tracheal intubation patients and delay tracheal intubation patients,total time of mechanical ventilation,hospital day decreased significantly (P<0.01) ,cure rate increased significantly (P<0.01) ,but complications [intermediate myasthenia syndrome (IMS) .pulmonary infection,cardiac damage and so on] had no significant difference(P>0.05). Conclusion It was exact that the therapeutic effect of timely tracheal intubation on rescuing the ASOPP patients, and the best time to tracheal intubation was in RF early period.
RESUMEN
Objective To observe the effect of bisoprulol on malignant ventricular arrhythmia (MVA) and heart rate turbulence (HRT) in ambulatory electrocardiogram monitoring for twenty-four hours in patients with unsta-ble angina pectoris (UAP). Methods 40 UAP patients with premature ventricu]ar beats were observed. All patients were examined with ambulatory electrocardiogram monitoring for twenty-four hours before and after bisoprolol (5mg, Qd) was administered for 7 days. The number of patients with MVA、turbulence onset (TO) and turbulence slope (TS) were analyzed. Results After bisoprolol was administered for 7 days in patients with UAP,the number of pa-tients with MVA decreased by 14.2%. TO decreased and TS increased, and HRT was improved. Conclusions HRT had clinical prognostic value for malignant ventricular arrhythmia and sudden death in patients with UPA. Bisoprolol can improve HRT and reduce the incidence of MVA.
RESUMEN
Objective To investigate the epidemiology of venous thromboembolism risk factors in hospitalized patients in department of cardiology,tumor,gerontism and orthopaedics. To analyze the frequency and category of protective measure. Methods The clinical data of 200 inpatients with high risk fators of venous thromboembolism were analyzed, the data including demography, sociology and information of prevention and cure. Results The patient with high risk fators of venous thromboembolism is a great deal ,with a ratio of male to female as 1.5 : 1. A peak of incidence was found at 60 to 79 years of age. The frequent risk factors include tumor, severe infection, congestive heart failure and ischemic stroke. The proportion of patients with high risk fator of venous thromboembolism is 7. 4%. The distribution of risk factor in different department is diverse. The ratio of adopting prophylactic anticoagulation correctly is very low. Conclusion The ratio of VTE cases in hospitalized patients is increasing,but the ratio of adopting correct therapy is very low. Clinical doctors have insufficient cognition yet. The clinical cognition and the prevention and cure of VTE should be strengthened urgently.
RESUMEN
Objective:To investigate the potential of differentiating into myocytes of the granulocyte colony stimulating factor(G CSF) and Simvastatin mobilized bone marrow stem cells. Methods:After injection of isoprenaline(ISO) interaperitoneally to develop acute ischemic model, rat bone marrow stem cells were mobilized by G CSF and dextran sulfate sodium salt and migrated to the site of myocardial infarction. Hearts were harvested from 24 hours to 24 weeks after administration of ISO for histopathological examination.Immunohistochemisty?HE and VG stain were used to detect infiltration of CD34 + monocytes and the regeneration of myocytes and the inhibition of fibroatrophy of ischemic myocardium.Results:24 hours after administration of ISO,a large amount of infiltrative monocytes and regenerative myocytes which were CD34 positive expression could be found in the infarct zones of the G CSF treatment group,while majority of the infiltrative inflammatory cells in control group were neutrophils and there was no infiltrative cells and myocytes which were CD34 positive expression,4 weeks after administration of ISO,there were a plenty of scar in control group,but not in the treatment group.Conclusion:Rat bone marrow stem cells were mobilized by G CSF and Simvastatin,and migrated to the site of myocardial infarction,and differentiated into viable cardiomyocytes or vascular endothelial.The heart function remarkably was improved by regeneration of myocytes,inhibition of fibroatrophy and protection of ischemic myocardial structure.
RESUMEN
The effects of continuous occlusion of thoracic or abdominal aorta (OTA or OAA) via intra-aortic balloon inflation on coronary perfusion pressure (CPP) were observed in 12 dogs after 10 min of cardiac fibrillation in comparison with those of different doses of epinephrine (0.02~0.14 mg/kg). The results showed that OTA could not increase CPP. However, during 30 min of cardiopu-Imonary resuscitation(CPR), every 3 min of OAA was followed by markedly increased CPP, 067 ~ 12kPa higher than the value in balloon deflation peritxl right before(P
