Abstract:
ObjectiveTo evaluate the effect of high-frequency jec ventilation and bilevel positive airway pressure (BiPAP) ventilation in the severe dyspnea caused by central airway stenosis and explore the deferent application of two ventilation models.MethodsA retrospective analysis was designed to collect the serious dyspnea patients caused by central airway stenosis from January 2006 to January 2009.The patients were divided into group H and group B according to the different ventilation models,and the effect of relieving dyspnea and ameliorating hypoxemia was compared.ResultsSeven cases were in group H,and 9 cases were in group B.The therapeutic effect of relieving dyspnea was 14.29 ％(1/7) in group H.There were only 4 cases accepting high-frequency jec ventilation and the effect of relieving dyspnea was 25.00％(1/4).Two cases failed in high-frequency jec ventilation treatment and succeeded in BiPAP treatment thereafter,and 1 case failed in BiPAP treatment initially but was treated effectively by high-frequency jec ventilation after dyspnea relapsed.In group B,there were only 6 cases accepting BiPAP ventilation and the effect ofrelieving dyspnea was 83.33％ (5/6),and after adding the cases who accepting the sequential therapy of high-frequency jec ventilation and BiPAP ventilation the effect rate was 88.89％ (8/9).The difference had statistical significance(P =0.006).In ameliorating hypoxemia,the effect rate of group H was 100.00％ (7/7),of group B was 88.89％(8/9),and the difference had no statistical significance (P =0.563 ).Conclusions The high-frequency je ventilation is effective to relieve hypoxemia but is short of relieving dyspnea and subjective symptom,and it is suit for life support preoperative and intraoperative.The BiPAP ventilation is effective to relieve dyspnea and subjective symptom and hypoxemia,so the treatment effect is better than high-frequency jec ventilation,and it is suit in relieving symptom temporarily,pre-operative preparation and malignant tumor palliative treatment.
