经鼻导管高流量吸氧与经鼻气道正压通气在重症毛细支气管炎呼吸支持中的应用价值比较

目的：比较经鼻导管高流量吸氧（HFNC）与经鼻气道正压通气（nCPAP）在重症毛细支气管炎呼吸支持中的应用价值，为临床治疗方案的选择提供参考。方法：选取2016年12月至2018年12月我院儿科收治的重症毛细支气管炎患儿90例，采用随机数字表法分为观察组和对照组各45例。两组患儿入院后均给予常规综合治疗以保证呼吸道通畅，在此基础上观察组采用HFNC治疗，对照组采用nCPAP治疗，比较两组患儿治疗前和治疗24 h后呼吸频率、经皮血氧饱和度（TcSO2）、呼吸窘迫评分体系（CSS）评分、动脉血氧分压（PaO2）等呼吸相关指标及治疗前后临床症状体征改善情况。结果：两组患儿治疗24 h后呼吸频率、CSS评分均降低，且观察组降低程度更大，TcSO2、PaO2于治疗24 h后升高，观察组升高幅度较对照组明显；治疗后两组患儿咳嗽及肺部湿啰音、肺部炎症情况均改善，观察组症状体征消失时间早于对照组，差异均有统计学意义（P<0.05）。结论：重症毛细支气管炎患儿采用HFNC治疗可明显改善通气功能和临床症状，治疗效果优于nCPAP治疗，可扩大样本量进一步观察。     

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.     

不同氧流量驱动肝素雾化吸入对老年COPD并呼吸衰竭患者血浆和肽素水平的影响

目的探讨不同氧流量驱动肝素雾化吸入用于老年慢性阻塞性肺疾病(COPD)并呼吸衰竭患者治疗的价值,分析患者血浆和肽素(Copeptin)水平所受影响。方法根据随机数字表法将120例COPD并呼吸衰竭患者分为A组、B组、C组,各40例。全部患者接受肝素雾化吸入治疗,A组氧流量为5 L/min,B组为7 L/min,C组为9 L/min,在肝素雾化吸入7 d后评价其治疗效果。分别于治疗前1 d、治疗3 d时、治疗7 d时,检测并对比三组血浆Copeptin水平、痰液黏稠度、呼吸力学指标、血气分析指标等变化情况,同时治疗期间记录患者不良反应发生情况。结果治疗3 d时、治疗7 d时,三组血浆Copeptin水平均较治疗前1 d呈下降趋势,肉眼观察痰液黏稠度呈下降趋势,B组下降速度快于其他两组,三组组间、时点、组间·时点比较,差异有统计学意义(P0.05),A、C两组比较,差异无统计学意义(P0.05);较治疗前1 d,三组呼吸力学指标均有变化,B组较其他两组气道峰值(Ppeak)、平台压(Pplat)、呼吸阻力(Raw)呈下降趋势,Cd呈上升趋势,三组组间、时点、组间·时点比较,差异均有统计学意义(P0.05),但A、C两组比较,差异无统计学意义(P0.05);三组治疗3 d时、治疗7 d时的动脉血氧分压(PaO_2)、氧合指数(PaO_2/FiO_2)水平均较治疗前1 d呈上升趋势,动脉血二氧化碳分压(PaCO_2)水平呈下降趋势,B组上升或下降速度高于其他两组,三组组间、时点、组间·时点比较,差异有统计学意义(P0.05);A、C两组比较,差异无统计学意义(P0.05);A、B两组治疗期间均未发生血小板减少等情况,C组2例出现轻度血小板减少,在及时处理后恢复正常。结论采用7 L/min氧流量驱动肝素雾化吸入治疗老年COPD并呼吸衰竭效果优于5 L/min与9 L/min的氧流量,利于降低患者血浆Copeptin水平,降低其痰液黏稠度,改善呼吸力学参数,增加胸肺动态顺应性,获得最佳雾化效果,且不良反应少。     

ICU患者撤机后不同吸氧方式对患者再次插管率和氧合指数的影响

目的探讨ICU患者撤机后不同吸氧方式对患者再次插管率和氧合指数的影响。方法选取122例ICU内气管插管行机械通气的患者作为研究对象,按照随机数字表法分成研究组和对照组,各61例。对照组患者在撤机后进行常规吸氧,研究组患者进行经鼻高流量吸氧,2组其他护理和治疗完全相同。观察并比较2组患者氧合指数变化情况以及再插管率情况。结果治疗后,研究组的再插管率(6. 6%)低于对照组(19. 7%),差异有统计学意义(P 0. 05);治疗后1、8、24 h,研究组呼吸频率、动脉血二氧化碳分压低于对照组,动脉血氧分压、氧合指数高于对照组,差异均有统计学意义(P 0. 05)。结论ICU患者撤机后经鼻高流量吸氧可有效降低再插管率,提高氧合指数,是一种有效的新型呼吸支持模式。     

疏肝和胃汤联合多潘立酮片治疗胆汁反流性胃炎的疗效分析

目的本次实验将采用疏肝和胃汤联合多潘立酮片对胆汁反流性胃炎患者开展临床治疗,分析病情改善成效。方法本次实验选取了2019年1月至2019年7月前来本院就诊的患者,其均为胆汁反流性胃炎人群,在自愿参与实验调查的基础上选取了78例患者作为调研对象。在分组上,为了保证公平性为随机分组。对照组患者采用多潘立酮片治疗措施,观察组则为疏肝和胃汤联合多潘立酮片治疗,分析应用成果。结果从治疗质量上看,观察组患者胆汁反流次数明显下降,且最长反流时间为(48.1±6.6)min,对照组为(35.1±5.1)min,组间对比差异较为显著,具有统计学意义(P <0.05)。与此同时,在腹痛腹胀、嗳气、胃灼烧等积分对比中,观察组的改善效果优于对照组,因此,我们认为观察组治疗方案更令人满意。结论采用疏肝和胃汤联合多潘立酮片进行胆汁反流性胃炎的治疗效果显著,有利于控制胆汁反流问题,改善胃炎病症,有利于患者的早日康复,可以推广应用。
