ABSTRACT
BACKGROUND:The outcome of cardiopulmonary resuscitation (CPR) may depend on a variety of factors related to patient status or resuscitation management. To evaluate the factors influencing the outcome of CPR after cardiac arrest (CA) will be conducive to improve the effectiveness of resuscitation. Therefore, a study was designed to assess these factors in the emergency department (ED) of a city hospital.METHODS:A CPR registry conforming to the Utstein-style template was conducted in the ED of the First Affiliated Hospital of Wenzhou Medical College from January 2005 to December 2011. The outcomes of CPR were compared in various factors groups. The primary outcomes were rated to return of spontaneous circulation (ROSC), 24-hour survival, survival to discharge and discharge with favorable neurological outcomes. Univariate analysis and multivariable logistic regression analysis were performed to evaluate factors associated with survival.RESULTS:A total of 725 patients were analyzed in the study. Of these patients, 187 (25.8％) had ROSC, 100 (13.8％) survived for 24 hours, 48 (6.6％) survived to discharge, and 23 (3.2％) survived to discharge with favorable neurologic outcomes. A logistic regression analysis demonstrated that the independent predictors of ROSC included traumatic etiology, first monitored rhythms, CPR duration, and total adrenaline dose. The independent predictors of 24-hour survival included traumatic etiology, cardiac etiology, first monitored rhythm and CPR duration. Previous status, cardiac etiology, first monitored rhythms and CPR duration were included in independent predictors of survival to discharge and neurologically favorable survival to discharge.CONCLUSIONS:Shockable rhythms, CPR duration ≤15 minutes and total adrenaline dose ≤5 mg were favorable predictors of ROSC, whereas traumatic etiology was unfavorable. Cardiac etiology, shockable rhythms and CPR duration ≤15 minutes were favorable predictors of 24-hour survival, whereas traumatic etiology was unfavorable. Cardiac etiology, shockable rhythms, CPR duration ≤15 minutes were favorable predictors of survival to discharge and neurologically favorable survival to discharge, but previous terminal illness or multiple organ failure (MOF) was unfavorable.
ABSTRACT
Objective To study the factors influenceing patients' family members to make own relative fac-tors patients' families making decision on refusal of cardiopulmonary resuscitation (CPR) to the critical patients. Method Data were registered based on Utstein Style of 522 patients aged over 15 years, who subjected to in-hos-pital cardiac arrest(CA) in Department of Emergency of The First Affiliated Hospital of Wenzhou Medical College from January 2005 to December 2008. A total of 157 patients' family made refusal decision among the 522 pa-tients, who belonged to the refusal group, and others belonged to the attempt resuscitation group. The associated factors included age, sex, marriage, household register, cause of CA, underlying diseases, capability of activity before CA, life supported with mechanical ventilation, and administration of pressor agents. The refusal decisions were evaluated by using univariate Logistical regression analysis, and then the statistical significant variables were analyzed by using muhivanate Logistical regression analysis. Results Age, household register, cause of CA(car-diac or traumatic),stroke, sudden death, cancer, capability of activity before CA, life supported with mechanical ventilation,and administration of pressor agents were the important factors of making refusal decision (P < 0.01), but sexes or marriage was insignificant related to the refusal decision (P > 0. O5). The independent risk factors re-lated to refusal decision were age (P = 0.034),cancer (P = 0.006),stroke (P = 0.003), and life supported with mechanical ventilation (P = 0.000) in multivariate Logistical regression analysis, but the protective factors were sudden death (P =0.000),cardiac CA (P =0.020) and traumatic CA(P =0.000). Conclusions Age over 60 years, cancer, stroke, and life suppoted with assisted ventilation before CA were factors associated with re-fusal decision making, yet sudden death, cardiac CA and traumatic CA were factors of accepting CPR.
