Abstract:
Objective:To evaluate the effectiveness of a mobile extracorporeal cardiopulmonary resuscitation (ECPR) team in treating cardiac arrest (CA) in the mountainous regions of southwest Zhejiang Province, and to provide clinical insights for ECPR in patients with prolonged low blood flow time in such areas.Methods:A retrospective analysis was conducted on 55 CA patients treated with ECPR at Lishui People's Hospital from June 2020 to June 2024. These patients were compared with 55 CA patients treated with ECPR in urban areas during the same period. The mobile team from our center established ECMO support at county-level hospitals before transferring patients to our hospital's ECMO treatment center for further care. General patient data and blood gas analysis results before and 2 hours after ECPR were collected. Clinical data differences between the two groups were compared, and factors influencing patient prognosis were analyzed using univariate and multivariate Cox regression analyses.Results:The average age of the patients was (52.45 ± 15.66) years, with an average low blood flow time of 151.42 ± 49.31 minutes. The 30-day survival rate was 23.64%, and the rate of good neurological recovery was 18.18%. Although the survival rate and good neurological function rate were lower than those of ECPR patients in urban areas, the differences were not statistically significant ( P > 0.05). Univariate Cox analysis revealed that defibrillation rhythm, low blood flow time, pH before and after ECMO, blood lactate levels before and after ECMO, and hemoglobin significantly influenced the prognosis of ECPR patients ( P < 0.05). Multivariate Cox analysis identified post-ECMO pH ( HR = 0.037) and post-ECMO blood lactate levels ( HR = 1.078) as independent prognostic factors for ECPR patients ( P < 0.05). Conclusions:Despite the longer low blood flow time in CA patients from mountainous areas, the mobile ECPR team can effectively enhance the treatment success rate of these patients through ECPR.
