RESUMO
Objective To observe the clinical significance of lung protective ventilation strategy in pa-tients with radiofrequency ablation of atrial fibrillation under general anesthesia through clinical controlled study. Methods Sixty patients undergoing radiofrequency catheter ablation were randomly divided into group L (n=30) and group C(n=30).Breathing parameters were set after tracheal intubation of general anesthesia.Arterial blood gas was collected.PETCO2and airway pressure were recorded during the operation.The operative time,ablation time,flu-oroscopy time and operation-related complications were recorded together with the surgeon satisfaction. Patients were followed up postoperatively for pulmonary complications. The length of patient′s hospital-stay was recorded. Results There was no significant difference in operation time, fluoroscopy time, ablation time and hospitalization days between the two groups (P>0.05). There was no significant difference in the occurrence and grade of PPCs between the two groups (P>0.05). There was significant difference in surgeon satisfaction between the two groups (P<0.01).Conclusion LPVS is suitable for ventilation management in radiofrequency ablation of atrial fibrillation.
RESUMO
<p><b>OBJECTIVE</b>In order to prove a basis for rational exploitation and utilization of the herb, the charaeteristic feature for Acanthus iliciflius was studied.</p><p><b>METHOD</b>The botanical and pharmacognostic features of the collected original plant were stadied.</p><p><b>RESULT</b>A. ilicifolius showed obvious pharmacognostic characters. The aerate cells of the root were upgrowth. and four vascular bundles were found in leaf venation.</p><p><b>CONCLUSION</b>The distinct characteristic features revealed in this studies can serve as evidence for the identification of A. ilicifolius.</p>
