ABSTRACT
This article analyzes and summaries the problems and difficulties existing in the first-aid medicine's clinical teaching.Combined with his own teaching experience,the author has made some exploration on the teaching time,the way of teaching and inspection form,which has got a good teaching effect.It provids the reference and development for the clinical teaching of first-aid medicine.
ABSTRACT
Objective To investigate the effects of sustained inflation (SI) combined with small tidal volume ventilation on lung recruitment and hemodynamics in patients with acute lung injury (ALI). Methods Patients with severe trauma followed by ALI were selected for this study. Patients underwent small tidal volume ventilation (baseline) for 1 h and then SI with 20 cm H 2O?30 s(SI 1), 30 cm H 2O?30 s(SI 2), 40 cm H 2O?30 s(SI 3) and 50 cm H 2O?30 s(SI 4) for 1 h, respectively. Parameters of pulmonary mechanics and hemodynamics were measured at 1 h after baseline, SI and returning baseline, respectively. Results Compared with those of the baseline, no changes of parameters were found after SI 1 and SI 2, but EELV and Cst increased significantly after SI 3 and SI 4. Paw, PAP and PVRI decreased significantly after SI 3 and SI 4. After SI interruption, all the physiological variables returned to baseline. SI had no significant effect on HR, AP and CI. Conclusion Treatment with SI combined with small tidal volume ventilation in patients with ALI can provide lung recruitment and improve lung compliance, but it has no significant side effect on hemodynamics.
ABSTRACT
Objective To evaluate the efficacy and safety of itraconazole injection in treatment of invasive fungal infection in the patients with multiple organ dysfunction syndrome.Methods Invasive fungal infection in 15 patients with multiple organ dysfunction syndrome was treated with 200 mg itraconazole injection,twice a day on the first two days,then once a day,for 8 to 14 days.During the treatment,the symptoms and signs,the results of chemical detection were recorded.Everyday fungus,sputum,stool smear or culture were performed.Results The recovery rate,effective rate,and fungal clearance in this trial with itraconazole injection were 80%(12/15),86.7%(13/15),and 86.7%(13/15) respectively.The side effect was not found.Conclusion Itraconazole injection is an effective and safe drug against invasive fungal infection in patients with multiple organ dysfunction syndrome.
