摘要
目的设计一种可保证水位的呼吸机自动补液加湿罐,并评价其在机械通气患者中的应用效果。方法选取2019年3月至6月在兰州大学第一医院重症监护病房行机械通气的患者38例,按照入院时间先后分为试验组18例和对照组20例,采用不同的呼吸机加湿罐。试验组使用自行设计的可保证水位的呼吸机自动补液加湿罐,对照组使用MR370加湿罐,两组均采用Fisher850机械加温加湿底座。评价两组患者在使用不同加湿罐机械通气48 h后痰液黏稠度为Ⅲ度的例数,24 h湿化装置加液的次数和总量,以及24 h清理管路冷凝水的次数和总量。结果试验组24 h湿化装置加液的次数明显少于对照组[(3.3±0.5)次比(11.2±1.7)次,P<0.01],其余结局指标差异无统计学意义(P>0.05)。结论对机械通气患者采用自行设计的呼吸机加湿罐,可使水位时刻维持在水位线处,有利于患者的湿化治疗,减少加液次数,能在一定程度上减轻医护人员的工作负担,值得临床推广。
Objective To design a ventilator humidifier that can ensure water level and infuse fluid automatically,and evaluate its application effect in patients with mechanical ventilation.Methods Thirty-eight patients who received mechanical ventilation in ICU from March to June in 2019 were included.According to the order of admission,they were divided into a study group with 18 patients and a control group with 20 patients.Different ventilator humidifiers were used.The study group used self-designed ventilator humidifier,and the control group used the MR370 humidifier.The cases of sputum viscosity withⅢdegree after 48 hours’mechanical ventilation,the times of fluid infusion and the total amount of fluid infusion were compared.The times of pouring out condensate water and the total amount of pouring out condensate water in 24 hours were also compared.Results The times of infusing liquid in the study group in 24 hours was less than that in the control group(3.3±0.5 vs.11.2±1.7,P<0.01),but the other indicators were not statistically significant between the two groups(all P>0.05).Conclusions The self-designed ventilator humidifier can be used for patients with mechanical ventilation,which can keep the water level at the water line all the time and is beneficial to humidification treatment.It can reduce the times of fluid infusion and nurses'workload.
