目的探讨无创正压通气(NIPPV)对多种原因所致的急性呼吸衰竭(ARF)的治疗效果。方法在常规内科治疗的基础上,32例各种原因引起的ARF患者加用无创正压通气(NIPPV)辅助呼吸治疗,选择同期住院ARF患者未用呼吸辅助治疗患者28例作为对照,对比分析两组治疗前后症状体征恢复时间、平均住院时间和血气分析变化情况。结果 NIPPV组症状体征改善时间和平均住院时间明显少于对照组(P<0.05);NIPPV治疗后6h,PaO2和PaCO2较治疗前改善明显(P<0.01)。结论 NIP-PV能迅速改善ARF患者的气体交换和生命体征,提高救治成功率,临床上应早期应用辅助通气,避免由于长期组织缺氧造成重要器官损害。
Objective To investigate the therapeutic effect of noninvasive positive pressure ventilation (NIPPV) on acute respiratory failure (ARF) caused by various causes. Methods Based on routine medical treatment, 32 ARF patients with various causes were treated with noninvasive positive pressure ventilation (NIPPV) adjuvant therapy, and 28 patients without ARS were enrolled in this study. Group before and after treatment of symptoms and signs recovery time, the average length of stay and blood gas analysis changes. Results The symptom and symptom improvement time and average length of hospital stay in NIPPV group were significantly less than those in control group (P <0.05). PaO2 and PaCO2 were significantly improved at 6h after NIPPV treatment (P <0.01). Conclusion NIP-PV can rapidly improve the gas exchange and vital signs of patients with ARF and improve the success rate of treatment. In the early stage, NIP-PV should be used to assist ventilation early to avoid the important organ damage caused by long-term hypoxia.
