Analysis Of Influencing Factors Of Return Of Spontaneous Circulation In-Hospital Adult Cardiac Arrest Patients

ObjectiveAnalyzing the clinical characteristics in Ningxia Medical University general hospital adult cardiac arrest and exploring the factors influencing the Return of Spontaneous Circulation in-hospital adult cardiac arrest patients,and providing reference for improving the success rate of cardiopulmonary resuscitation in-hospital.MethodsRetrospective analyzing the clinical data of 218 adult cardiac arrest patients who was cured by cardiopulmonary resuscitation during hospitalization in Ningxia Medical University genera Hospital from January 1,2016 to December 31,2018.Return of spontaneous circulation group(ROSC group)and Non-Return of spontaneous circulation group(Non-ROSC group)were classified as the end point of restoring spontaneous circulation.The clinical data of the two groups were compared by SPSS20.0 statistical software,and the multivariate logistic regression analysis was performed on the statistically significant factors of univariate analysis.The factors influencing the ROSC of adult cardiac arrest patients in hospital were obtained.Results1.A total of 218 patients were enrolled in the study,including 143 males and 75females,with a male to female ratio of 1.9:1;the youngest was 18 years old,the largest was89 years old,and the average age was 66(51,73)years;100 cases were recovered,118 cases were not recovered,and the rate of ROSC was 45.9%.The location of cardiac arrest was mainly in cardiology and intensive care units.The onset time was mainly in winter and8:00~11:59 am.Cardiogenic diseases are dominant,and the initial heart rhythm is mostly non-defibrillable rhythm;2.Univariate analysis showed that between the ROSC group and the non-ROSC group there was statistically significant in defibrillable rhythm(?~2=5.980,P<0.05),tracheal intubation(?~2=4.637,P<0.05),and electrical defibrillation(?~2=3.958,P<0.05).),time from cardiac arrest to initial chest compression(t=-5.401,P<0.05),duration of CPR(Z=-9.750,P<0.05),adrenaline dose(Z=-4.153,P<0.05)the difference was statistically significant(P<0.05);there was no significant difference in gender,age,smoking,alcohol,hypertension,diabetes,coronary heart disease and primary disease(P>0.05).3.Multivariate logistic regression analysis showed that the difference between the ROSC group and the non-ROSC group in the time from CA to CPR(OR=1.097,95%CI 1.127)-1.733,P=0.002)and CPR duration(OR=1.102,95%CI 1.070-1.135,P=0.000)was statistically significant(P<0.05).Conclusion 1.Adult cardiac arrest patients in-hospital are more common in elderly men,the highest incidence in cardiogenic diseases,cardiology,intensive care unit,AM and in winter,the initial heart rhythm is mostly non-defibrillable rhythm;2.The time from CA to start CPR and the duration of CPR may be independent risk factors with ROSC of in-hospital adult cardiac arrest patients.
