目的总结52例带有人工气道患者非机械通气时气道湿化的护理体会。方法持续气道加温湿化;充分补充水分,保证液体平衡;加强基础护理及心理护理;严密观察病情,准确评估湿化效果。结果 52例患者中有3例出现湿化过度,改为间断湿化。均无气道阻塞、出血、痰痂形成,湿化效果满意。结论对非机械通气人工气道患者气道湿化时采取正确的护理方法,可提高湿化效果,避免并发症的发生。     

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.     

高流量吸氧与面罩吸氧在胸腔镜辅助食管癌根治术后氧疗效果对比

目的观察高流量湿化吸氧与常规面罩吸氧在食管癌患者行胸腔镜辅助食管癌根治术后治疗的临床效果。方法将36例择期行胸腔镜辅助下食管癌根治术后患者随机分为常规面罩吸氧对照组(A组)和高流量湿化吸氧治疗组(B组),对两组患者治疗2 h、6 h和24 h后的呼吸频率、动脉血气分析等指标进行比较,了解两种吸氧方式在食管癌患者行胸腔镜辅助食管癌根治术后治疗上的优劣。结果两组患者治疗2 h、6 h和24 h的呼吸频率、动脉血气分析发现,A组动脉氧饱和度、动脉血氧分压较B组降低,动脉血二氧化碳分压、呼吸频率较B组增高,两组比较差异有统计学意义(均P0.01)。结论与常规面罩吸氧比较,高流量湿化面罩吸氧可以使胸腔镜辅助食管癌根治术后患者有更满意的氧合效果,值得在临床上推广。     

一种简便的呼吸机湿化器加水方法

使用呼吸机辅助呼吸，在湿化器加水过程中，我院传统的加水方法为用50ml注射器抽吸灭菌注射用水，加入湿化器中，每次加水要反复抽吸灭菌注射用水多次才能加至所需的刻度。在临床实践中发现这样加水费力、费时，现摸索出一种简便、易行的加水方法，介绍如下。
