Application effectiveness of root cause analysis in emergency cardiopulmonary resuscitation and its impact on the prognosis of patients

Objective:To investigate the application effectiveness of root cause analysis in emergency cardiopulmonary resuscitation and its impact on the prognosis of patients, and to further provide ideas to improve the outcome of emergency medicine departments.Methods:A total of 112 patients with cardiac arrest(CA)admitted to the Emergency Department of Wuzhou Workers’Hospital from January 2020 to January 2022 were selected and divided into control group and observation group, with 56 cases in each group.In the control group, conventional intervention was adopted, and in the observation group, an intervention strategy based on root cause analysis was adopted, The survival rate after cardiopulmonary resuscitation, the ventilator maintenance time, ICU stay time, as well as heart rate (HR), mean arterial pressure (MAP), arterial partial pressure of oxygen (PaO₂), arterial partial pressure of carbon dioxide (PCO₂) and respiratory rate before and after resuscitation were compared between the two groups.The Depression Anxiety Stress Scale-21(DASS-21)score was evaluated at 1 d, 5 d and 7 d after waking up, and the occurrence of complications was observed.Results:The survival rate after cardiopulmonary resuscitation in the observation group was 48.21%, which was not significantly different from that in the control group (41.07%) (P> 0.05).The ventilator maintenance time and ICU stay time in the observation group were shorter than those in the control group, HR, MAP, PaO₂ and respiratory rate after resuscitation were higher than those in the control group, and PCO₂ was lower than that in the control group (all P< 0.05).The DASS-21 scale scores of all dimensions were lower in the observation group than in the control group at 5 d and 7 d after waking up (P< 0.05); the complication rate of 11.11% in the observation group was not significantly different from that of 26.09% in the control group (P> 0.05).Conclusion:The intervention strategy based on root cause analysis applied in emergency cardiopulmonary resuscitation can significantly enhance the salvage effect, and improve the psychological status, body blood gas and hemodynamic parameters of patients.
