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OA

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 mmHgvs40.65±3.79 mmHg),MCP-1(58.45±11.94 ng/Lvs74.46±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.
