目的 观察重症加强治疗病房气管切开患者撤机后应用呼吸湿化治疗仪的临床疗效。 方法 将气管切开患者分成观察组(AIRVO2 呼吸湿化治疗仪组)和对照组(呼吸机湿化装置联合气切面罩加温湿化给氧组),各 50 例。在常规治疗基础上,观察两组撤机后 0、6、12、24、48、72 h 血气指标(pH、PaO2、PaCO2、PaO2/FiO2)、临床症状指标(心率、呼吸频率、血氧饱和度)、呼吸浅快指数(RSBI)、痰液黏稠度、肺部感染率、脱机成功率及日均撤机费用等指标并进行比较。 结果 在常规治疗基础上,两组经不同方案治疗后各项指标均取得明显改善。相同时间点痰液黏稠度气道湿化效果观察组明显优于对照组,差异有统计学意义(P<0.05)。治疗后各时点两组的心率、呼吸频率、血氧饱和度等指标较治疗前均有明显改善,且治疗后两组间相比较差异有统计学意义(P<0.05)。两组患者上述血气指标经治疗后均取得明显改善,不同时间点 PaO2、PaCO2 改善情况两组相比差异有统计学意义(P<0.05)。治疗 72 h 后,观察组 RSBI、肺部感染率均低于对照组,脱机成功率高于对照组,差异有统计学意义(P<0.05)。观察组患者平均每住院日撤机单项费用低于对照组,差异有统计学意义(P<0.05)。观察组再次出现低氧血症 1 例,对照组出现低氧血症 9 例,需重新进行机械通气。 结论 重症加强治疗病房气管切开患者撤机后应用呼吸湿化治疗仪能取得较好的治疗效果,具有良好的临床推广应用价值。

Objective To investigate the clinical efficacy of AIRVO2 respiratory humidification apparatus in patients with tracheotomy after successful weaning from mechanical ventilation in intensive care unit (ICU). Methods One hundred subjects were randomly divided into a control group (treated with the tracheotomy mask joint oxygen inhalation by heating humidifier, n=50) and an observation group (treated with AIRVO2 model, n=50) on the basis of conventional therapy. Blood gas indexes (pH, PaO2, PaCO2, PaO2/FiO2) and clinical data (heart rate, respiratory rate, SpO2, sputum viscosity) were recorded at 0 h, 6 h, 12 h, 24 h, 48 h, 72 h after weaning. Besides, the incidence of postoperative pulmonary infection, rapid shallow breathing index (RSBI), successful weaning rate from mechanical ventilation and daily cost of weaning between the two groups were compared at 72 h after weaning. Results After treatment, all observed data of the patients were obviously improved compared with those before treatment. The differences of humidification effects between the observation group and the control group at the same time point were statistically significant (P<0.05). The differences of heart rate, respiratory rate, and SpO2 between the observation group and the control group at the same time point were statistically significant (P<0.05). The improvement of PaO2 and PaCO2 at the same time point were statistically different between the observation group and the control group (P<0.05). Seventy-two hours after weaning, the incidence of postoperative pulmonary infection and RSBI in the observation group were significantly lower than those in the control group (P<0.05), successful weaning rate from mechanical ventilation in the observation group was significantly higher than that in the control group (P<0.05), and the average daily cost of weaning from mechanical ventilation in the observation group was lower than that in the control group (P<0.05). Nine patients in the control group and 1 patient in the observation group needed secondary mechanical ventilation due to hypoxemia. Conclusion The therapy of AIRVO2 respiratory humidification apparatus combined with conventional treatment may achieve satisfactory effect for patients of successful weaning from mechanical ventilation with tracheotomy, and it is worthy of promotion in clinical use.
