目的 探讨计划-实施-检查-处理（PDCA）循环法及根本原因分析法在持续正压通气治疗重症肺炎患儿中的应用效果。方法 选取2021年1月—2023年1月医院收治并接受鼻塞式持续正压通气治疗的重症肺炎患儿80例,基于随机数字表法分为两组,每组各40例。对照组接受常规护理,观察组采用PDCA循环法联合根本原因分析法护理干预。比较两组临床症状改善时间、血气指标[动脉血氧分压（PaO₂）、动脉血氧饱和度（SaO₂）、动脉血二氧化碳分压（PaCO₂）]、肺功能指标[第1秒用力呼气容积（FEV₁）、潮气量（VT）]、炎症免疫指标[单核细胞趋化蛋白-1（MCP-1）、可溶性髓系细胞触发受体-1（sTREM-1）、可溶性细胞间黏附分子-1（sICAM-1）]水平变化,比较两组患儿家属满意度情况。结果 观察组患儿咳嗽、气促、哮鸣音、心率恢复及紫绀等症状改善用时均低于对照组,比较差异有统计学意义（P<0.05）。干预前,两组患儿PaO₂、SaO₂、PaCO₂、FEV₁、VT、MCP-1、sTREM-1、sICAM-1水平比较差异均无统计学意义（P>0.05）;干预后,两组患儿上述指标水平均有不同程度变化（P<0.05）,观察组PaO₂（97.18±7.90 mmHg vs 90.30±7.12 mmHg）、SaO₂（93.58±3.82% vs 86.30±4.21%）、FEV₁（2.66±0.46 L vs 1.97±0.34 L）、VT（11.92±1.89% vs 9.83±1.10%）水平均高于对照组,观察组PaCO₂（36.70±3.97 mmHg vs 40.65±3.79 mmHg）、MCP-1（58.45±11.94 ng/L vs 74.46±16.69 ng/L）、sTREM-1（36.25±8.30 ng/L vs 51.57±9.51 ng/L）、sICAM-1（187.52±31.22 mg/L vs 243.73±46.79 mg/L）水平低于对照组,差异均有统计学意义（P<0.05）。观察组患儿家属满意度整体优于对照组（P<0.05）;观察组总满意率（97.5% vs 77.5%）高于对照组,差异有统计学意义（P<0.05）。结论 PDCA循环法及根本原因分析法应用于接受持续正压通气治疗的重症肺炎患儿,能够有效促进患儿临床症状改善,有利于血气及肺功能恢复,且可降低炎症反应,患儿家属满意度较高。

Objective To explore the application effect of Plan-Do-Check-Action（PDCA）circulation method and root cause analysis method in the treatment of children with severe pneumonia with continuous positive pressure ventilation．Methods From January 2021 to January 2023,80 children with severe pneumonia who were admitted to hospital and received nasal plug continuous positive pressure ventilation treatment were enrolled in this study．Based on the random number table method,they were divided into two groups,with 40 cases in each group．The control group received routine nursing,while the observation group received PDCA circulation method combined with root cause analysis nursing intervention．The improvement time of clinical symptoms,changes in blood gas indicators[arterial partial oxygen pressure（PaO₂）,arterial oxygen saturation（SaO₂）,arterial partial pressure of carbon dioxide（PaCO₂）],lung function indicators [（forced expiratory volume in 1 second,FEV₁）,tidal volume（VT）],and inflammatory immune indicators [monocyte chemotactic protein-1（MCP-1）,soluble myeloid cell trigger receptor-1（sTREM-1）,soluble intercellular adhesion molecule-1（sICAM-1）] levels between the two groups were compared,and the family members’ satisfaction of the two groups was also compared．Results The improvement time for symptoms such as cough,shortness of breath,wheezing,heart rate recovery and cyanosis in the observation group was lower than that in the control group,and the difference was statistically significant（P<0.05）．Before intervention,there was no statistically significant difference in the levels of PaO₂,SaO₂,PaCO₂,FEV₁,VT,MCP-1,sTREM-1 and sICAM-1 between the two groups of children（P>0.05）．After intervention,the levels of the above indicators in both groups of children showed varying degrees of change（P<0.05）．The levels of PaO₂（97.18±7.90 mmHg vs 90.30±7.12 mmHg）,SaO₂（93.58±3.82% vs 86.30±4.21%）,FEV₁（2.66±0.46 L vs 1.97±0.34 L）,VT（11.92±1.89% vs 9.83±1.10%）in the observation group were higher than those in the control group．The levels of PaCO₂（36.70±3.97 mmHg vs 40.65±3.79 mmHg）,MCP-1（58.45±11.94 ng/L vs 74.46±16.69 ng/L）,sTREM-1（36.25±8.30 ng/L vs 51.57±9.51 ng/L）and sICAM-1（187.52±31.22 mg/L vs 243.73±46.79 mg/L）in the observation group were lower than those of the control group,with statistically significant differences（P<0.05）．The overall satisfaction of the observation group was better than that of the control group（P<0.05）,the total family members’ satisfaction rate of the observation group was higher than that of the control group（97.5% vs 77.5%）,with a statistically significant difference（P<0.05）．Conclusions PDCA circulation method and root cause analysis method applied to children with severe pneumonia who receive continuous positive pressure ventilation treatment,can effectively promote the improvement of clinical symptoms,be conducive to the recovery of blood gas and lung function,and reduce inflammatory reaction,with high family members’ satisfaction．

目的 探究质控预警系统在重症患儿连续性血液净化治疗的应用效果。方法 随机选取于2020年1月—2021年12月在我院进行连续性血液净化治疗的共80例重症患儿作为本次研究对象,将80例患儿随机分成研究组和对照组,对照组进行常规护理,研究组则在常规护理的基础上行预警系统质量控制,对比2组患儿连续性血液净化治疗时长及报警频次、2组患儿在不同治疗时间段内滤器凝血发生率、2组非计划下机发生情况及2组患儿家属的护理满意度。结果 研究组平均报警频次为(8.60±3.35),低于对照组(16.52±7.41)的报警频次。而研究组的治疗时长(32.54±6.73 h)较对照组(21.38±5.61 h)延长,研究组患儿在进行连续性血液净化治疗的过程中,在8小时至24小时之间及大于24小时滤器的凝血发生率低于对照组,研究组和对照组护理满意度分别为92.50%和75.00%,对比差异显著。结论 在对重症患儿进行连续性血液净化治疗过程中应用质控预警系统具有较高的临床使用价值,不仅可以有效降低报警频次及滤器凝血发生率,而且对延长治疗时间有显著的促进作用,值得在今后的治疗过程中大力推广。

Objective To explore the application effect of quality control early warning system in continuous blood purification treatment of critically ill children.Methods A total of 80 critically ill children who underwent continuous blood purification treatment in our hospital from January 2020 to December 2021 were randomly selected as the research object, and were randomly divided into observation group and control group.The control group received routine nursing,and the observation group received early warning system quality control on the basis of routine nursing.The duration and alarm frequency of continuous blood purification treatment,the incidence of filter coagulation in different treatment periods,the occurrence of unplanned quitting and nursing satisfaction of the two groups were compared.Results The average alarm frequency of the observation group was (8.60±3.35),which was significantly lower than that of the control group (16.52±7.41).However,the treatment duration of the observation group (32.54±6.73 h) was significantly longer than that of the control group (21.38±5.61 h).During continuous blood purification treatment,the incidence of blood coagulation in the observation group was lower than that of the control group,and the nursing satisfaction of the observation group and the control group were 92.50% and 75.00% respectively,with significant differences.Conclusions The application of quality control early warning system in the continuous blood purification treatment of critically ill children has a high clinical value,which can not only effectively reduce the alarm frequency and the incidence of filter coagulation,but also significantly prolong the treatment time,and it is worth promoting in the future treatment process.
