经鼻高流量氧气湿化治疗老年慢性阻塞性肺疾病急性加重合并呼吸衰竭的可行性研究

ObjectiveTo investigate the feasibility of transnasal heated humidified high flow nasal cannula oxygen therapy (HFNC) in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) with respiratory failure in elderly patients. MethodsA total of 176 elderly patients with AECOPD complicated with respiratory failure who were hospitalized at Peking University Shougang Hospital from December 2016 to January 2022 were enrolled, including 82 patients in an HFNC group and 94 patients in an NPPV group. After treatment, pulse oxygen saturation (SPO₂), arterial partial pressure of carbon dioxide (PaCO₂), oxygenation index (OI), respiratory rate (RR), heart rate (HR), mean arterial pressure (MAP), comfort score, discharge rate, rate of endotracheal intubation, rate of transfer to intensive care unit (ICU), and mortality were compared between the two groups. The independent sample t-test was used for comparison between the two groups. Statistical data are expressed in percentage or number of cases and the χ² test was used for their comparisons. ResultsThe SPO₂ values at 30 min, 1 h, and 6 h were significantly higher in the HFNC group than in the NPPV group (t=-2.049,-2.618, and -3.314, P=0.043, 0.010, and 0.001, respectively). SPO₂ before discharge was significantly lower than that of the NPPV group (t=2.162, P=0.033), but OI at each time point and before discharge had no statistical significance (P＞0.05). MAP at 6 h was significantly higher in the HFNC group than in the NPPV group (t=-2.209, P=0.029), but within the normal range. HRs at 2 h and 3 h in the HFNC group were significantly higher than those of the NPPV group (t=-2.199 and -2.336, P=0.030 and 0.021, respectively). There were no significant differences in RR, HR, or MAP between the two groups at other time points and before discharge (P＞0.05). There was no significant difference in PaCO2 between the two groups (P＞0.05). Comfort score in the HFNC group was significantly higher than that of the NPPV group (t=-46.807, P＜0.001). There were no significant differences in discharge rate, ICU transfer rate, endotracheal intubation rate, and mortality between the two groups (P＞0.05). ConclusionHFNC is as effective as NPPV in treating elderly patients with AECOPD complicated with type Ⅰ or mild type Ⅱ respiratory failure, and HFNC is more comfortable than NPPV.     

适应性支持通气在老年慢性阻塞性肺疾病并发呼吸衰竭患者呼吸机应用中临床价值

目的观察适应性支持通气在老年慢性阻塞性肺疾病并发呼吸衰竭患者呼吸机应用中的临床价值。方法选取自2016年1月至2018年6月首都医科大学附属北京朝阳医院收治的121例老年慢性阻塞性肺疾病并发呼吸衰竭患者为研究对象。所有患者均接受呼吸机治疗,根据机械通气模式不同,将患者分入A组(同步间歇指令通气,n=60)和B组(适应性支持通气,n=61)。比较两组患者的呼吸动力学相关指标(呼吸频率、吸气阻力、内源性呼气末正压、第0.1秒气道闭合压、静态肺顺应性),呼吸机撤机时间和撤机成功率,不同时间点(通气前、通气2 h、拔管前)血气分析值(pH值、氧分压、二氧化碳分压)。结果 B组患者呼吸频率、吸气阻力、内源性呼气末正压均低于A组,第0.1秒气道闭合压、静态肺顺应性均高于A组。两组比较,差异有统计学意义(P<0.05)。B组患者呼吸机撤机时间短于A组,撤机成功率高于A组,两组比较,差异均有统计学意义(P<0.05)。两组患者通气前、通气2 h、拔管前的pH值、氧分压呈逐渐上升趋势,二氧化碳分压呈逐渐下降趋势;本组3个时间点的pH值、氧分压、二氧化碳分压两两比较,差异均有统计学意义(P<0.05)。结论老年慢性阻塞性肺疾病并发呼吸衰竭患者呼吸机应用中采用适应性支持通气模式,可促进患者自主呼吸功能恢复,减少通气时间,提高撤机成功率,安全性较好。     

下肢正压支撑跑台训练联合肌内效贴在肌肉骨骼损伤康复中的应用及对患者平衡能力与运动功能的影响

目的探讨下肢正压支撑跑台训练联合肌内效贴在肌肉骨骼损伤康复中的应用及对患者平衡能力与运动功能的影响。方法选取2016年8月-2018年8月我院收治的肌肉骨骼损伤患者68例,按照随机数字表法分为对照组和研究组,各34例。对照组应用下肢正压支撑跑台训练治疗,研究组在对照组基础上加用肌内效贴治疗。比较两组治疗效果。结果研究组徒手肌力评定(MMT)评分高于对照组(P0.05),研究组改良Ash-worth量表(MAS)评分低于对照组(P0.05);研究组Berg平衡量表(BBS)评分高于对照组(P0.05),研究组计时起立行走测试(TGUT)低于对照组(P0.05);研究组步长、步宽以及步速均优于对照组(P0.05)。结论在针对肌肉骨骼损伤患者进行康复治疗的过程中,下肢正压支撑跑台训练联合肌内效贴可以有效促进患者平衡能力以及运动功能的恢复,有助于患者康复。
