Abstract：Objective:To investigate the effects of external cardiopulmonary resuscitation(ECPR)and traditional cardiopulmonary resuscitation(CCPR)in patients with emergency respiratory cardiac arrest based on blood oxygen saturation and complication rate.Methods:The data of 60 patients with emergency respiratory cardiac arrest in Luoyang Central Hospital Affiliated to Zhengzhou University from April 2022 to April 2024 were retrospectively analyzed.30 patients treated with CCPR were classified as CCPR group by 1∶1 pairing principle,and 30 patients treated with ECPR after failing CCPR treatment were classified as ECPR group.Comparing the treatment conditions of the two groups[success rate of cardiopulmonary resuscitation(CPR),success rate of restoring spontaneous circulation(ROSC rate)],oxygen metabolism indexes(oxygen load,oxygen consumption,arterial oxygen content),blood gas analysis indexes(oxygen saturation,oxygenation index,blood lactic acid),hemodynamics[coronary perfusion pressure(CPP),total ejection fraction(GEF),cardiac output volume(CO),mean arterial pressure(MAP)]and the incidence of complications.Results:The success rate of CPR in ECPR group was 63.33%(19/30),higher than that in CCPR group,33.33%(10/30),with statistically significant difference(P＜0.05).The ROSC rate in ECPR group was 66.67%(20/30)higher than that in CCPR group,40.00%(12/30),with statistically significant differences(P＜0.05).Blood oxygen saturation,oxygenation index,oxygen load,oxygen consumption and arterial oxygen content in ECPR group were higher than those in CCPR group at 30 min after resuscitation,and blood lactic acid was lower than that in CCPR group,with statistically significant differences(P＜0.05).The 30 min CPP,GEF,CO and MAP of ECPR group were higher than those of CCPR group,with statistically significant differences(P＜0.05).The complication rate of ECPR group was 10.00%(3/30)compared with CCPR group 20.00%(6/30),and the difference was not statistically significant(P＞0.05).Conclusion:Compared with CCPR,ECPR has a better therapeutic effect,which is helpful to regulate oxygen metabolism,improve hemodynamics,and promote the recovery of blood gas analysis indexes,and has a certain safety.
