【摘要】 目的：探究心脏骤停（CA）患者心肺复苏（CPR）自主循环恢复后（ROSC）预后的相关因素，为提高CPR成功率提供临床经验。方法：回顾性分析广东省梅州市人民医院2018年1月到2021年2月525例CPR患者的基线资料、入院信息、CPR信息、治疗情况和结局。结果：以ROSC分组并建立Logistic回归模型，未ROSC组CPR持续时间高于ROSC组（34.39±11.56 min vs 18.59±16.66 min,P<0.001）;CPR所致胸部损伤OR值0.277(95%CI:0.115-0.670)）和CPR持续时间OR值0.006(95%CI:0.002-0.017)可能是ROSC的独立影响因素。以出院状态分组并建立Logistic回归模型，存活出院组CPR持续时间高于非存活出院组（22.08±19.10 min vs 15.86±14.05 min,P=0.041）；以“非存活出院”为参考状态，CPR持续时间、CPR所致胸部损伤和入院时间可能是患者存活出院的影响因素，OR值分别为0.951(95%CI:0.915-0.988),4.457(95%CI:1.297-15.316)和3.222(95%CI:1.247-8.324)。结论：CPR持续时间和CPR所致胸部损伤是CA患者ROSC和存活出院的独立影响因素，应多关注以上指标，以提高CA患者救治成功率。更多还原

【Abstract】 Objective:To explore the prognostic factors of cardiopulmonary resuscitation(CPR)in patients with cardiac arrest(CA),so as to provide clinical experience for treating patients and improving the success rate of CPR.Methods:525 patients suffered from CA in Meizhou People’s Hospital of Guangdong Province from Jan 2018 to Feb2021 and were rescued by CPR were selected. Baseline data,information of admission andCA,treatment status and outcome variables were analyzed retrospectively. Results:By grouping with ROSC and establishing logistic regression model,the duration of CPR in the non ROSC group was very significantly higher than that in the ROSC group(34.39±11.56min vs 18.59±16.66 min,P<0.001). The results showed that the chest injury caused by CPR(OR 0.277,95% CI:0.115-0.670)and the duration of CPR(OR 0.006,95% CI:0.002-0.017)might be independent influencing factors of ROSC.Accorded to the grouping of discharge status and the establishment of logistic regression model,the duration of CPR in the survival discharge group was significantly higher than that in the non survival discharge group(22.08±19.10 min vs15.86±14.05 min,P=0.041). With the“non survival discharge”as the reference status,the duration of CA,chest injury caused by CA and hospital admission time may be the influencing factors for the survival and discharge of patients,with OR values of 0.951(95% CI:0.915-0.988),4.457(95% CI:1.297-15.316)and 3.222(95% CI:1.247-8.324). Conclusion:The duration of CPR and chest injury caused by CPR are independent influencing factors for ROSC and survival and discharge of CA. More attention should be paid to the above indicators to improve the success rate of CA.更多还原
