RESUMO
Objective:To study the effect of magnetic nursing concept on improving nurses' nursing ability of extracorporeal membrane oxygenation (ECMO).Methods:In the study, 33 nurses of emergency intensive care unit of The First Affiliated Hospital of Nanjing Medical University from January 2019 to December 2020 were selected as the research objects. From January 2019 to December 2019, the Department carried out routine nursing management, and from January 2020 to December 2020, the Department implemented the management mode of magnetic nursing concept. The mastery of nursing knowledge of ECMO was analyzed by using scale, and the critical thinking ability and self-study ability of the nurses were compared before and after intervention. SPSS 22.0 was used to perform t test on the data. Results:After the intervention, nurses' mastery of respiratory system nursing, circulatory system nursing, fluid balance nursing, skin nursing, digestive system nursing, bleeding, anticoagulant problem nursing, hospital infection prevention and control, and pipeline nursing related knowledge of ECMO patients was significantly better than that before the intervention ( P<0.05). After the intervention, nurses' truth-seeking, open thinking, systematic ability, analytic ability, thinking self-confidence, thirst for knowledge, cognitive maturity and total scale scores were significantly higher than those before the intervention ( P<0.05). After the intervention, nurses' self motivation belief, task analysis, self-monitoring and regulation, self-evaluation and total score were significantly higher than those before the intervention ( P<0.05). Conclusion:The nursing management mode of magnetic nursing concept is of value in improving nurses' autonomous learning ability and critical thinking ability.
RESUMO
Objective:To summarize the clinical characteristics and influencing factors on clinical outcome of patients receiving extracorporeal cardiopulmonary resuscitation (ECPR).Methods:A total of 78 patients receiving ECPR admitted to the Department of Emergency Medicine of the First Affiliated Hospital of Nanjing Medical University (Jiangsu Provincial People’s Hospital) from March 2015 to December 2020 were retrospectively enrolled. Patients were divided into the survival group and death group according to clinical outcome. Their baseline data, CPR associated parameters, and pre-ECPR laboratory tests were compared between the two groups.Results:Of the 78 included patients, 51 patients were male and 27 female. Twenty-three patients finally survived, including 10 males and 13 females. There were no significant differences in age, body mass index and underlying diseases (hypertension, diabetes and coronary heart disease) between the two groups (all P > 0.05). The proportion of male patients in the survival group was lower than that in the death group ( P=0.017). Meanwhile Survival After Veno-Arterial ECMO (SAVE) score was significantly higher in the survival group than that in the death group[ (-1.57±4.15) vs. (-9.36±5.36), P<0.001]. The proportion of by-stander CPR in the survival group was higher than that in the death group ( P=0.014). The pre-ECPR serum AST, ALT, and Cr levels in the survival group were significantly lower than those in the death group (all P<0.05). Logistic regression analysis showed that by-stander CPR ( OR=0.114, 95% CI: 0.015~0.867, P=0.036) and SAVE score ( OR=0.625, 95% CI: 0.479~0.815, P=0.001) were independent risk factors predicting ICU death in patients receiving ECPR. Conclusions:ECPR is an efficient tool to improve clinical outcomes of patients with cardiac arrest. By-stander CPR and SAVE score are independent risk factors predicting ICU death in patients receiving ECPR.
RESUMO
Objective:To study the application of blood products in patients with veno-arterial extracorporeal membrane oxygenation (VA-ECMO) and evaluate its effect on the prognosis.Methods:A total of 83 adult patients treated with VA-ECMO in the Emergency Department of the First Affiliated Hospital of Nanjing Medical University from January 2017 to January 2020 were grouped by survival to explore the risk factors of 28-day mortality using binary logistic regression, and the threshold was calculated by ROC curve.Results:Platelet transfusion ( OR=2.506, 95% CI: 1.142-5.499) and non-myocarditis disease ( OR=6.881, 95% CI: 1.615-29.316) were the risk factors of 28-day mortality in adult VA-ECMO patients. The threshold of platelet transfusion was 0.427 mL/(kg·d) (sensitivity 78.4%, specificity 69.6% , AUC 0.735). Conclusions:The increased platelet transfusion is related to the poor prognosis of adult patients with VA-ECMO. Refractory myocarditis patients are better treated with VA-ECMO.
RESUMO
Objective:To analyze the early volume characteristics of patients with severe cardiogenic shock treated with veno-arterial extracorporeal membrane oxygenation (VA-ECMO) and the relationship between their early volume and the prognosis.Methods:This study reviewed patients of Emergency Medical University , treated with VA-ECMO and screened the patients with severe cardiogenic shock and VA-ECMO running more than 72 h for further study. The basic condition of the patients was recorded, and the fluid balance in the first 72 h was analyzed. The patients were grouped according to their fluid balance in the first 72 h. The gender, age, survival rate, continuous renal replacement therapy (CRRT) rate, intra-aortic balloon pump (IABP) rate, and invasive mechanical ventilation rate were compared between the two groups, and the relative risk to the prognosis was calculated. The prognosis was compared between the two groups. Results:Totally 77 patients with severe cardiogenic shock were enrolled. Forty-one cases survived, with an overall survival rate of 53.2%. The volume balance at 48-72 h and the total volume balance at the first 72 h were different between the survival and dead groups. Compared with the positive balance group, patients in the negative balance group were less likely to receive CRRT or invasive mechanical ventilation during the first 72 h. Patients in the negative balance group during the first 72 h had a better survival rate, and their relative risk of survival was 1.81 (95% confidence interval: 1.101, 2.985). However, there was no significant difference in survival rate according to every 24 h fluid balance.Conclusions:Patients with severe cardiogenic shock treated with VA-ECMO who had negative total volume balance during the first 72 h are more likely to survive and less likely to require CRRT or invasive mechanical ventilation.
RESUMO
Objective:To summarize the inter-hospital transport experience on extracorporeal membrane oxygenation (ECMO) led by a team from emergency department.Methods:The clinical data of 21 patients transferred under the support of ECMO between December 2016 and February 2019 were retrospectively analyzed. All patients were transferred to the First Affiliated Hospital of Nanjing Medical University from other hospitals. Interhospital distance, transport methods, patient demorgraphic characteristics, disease diagnosis, intubation location, intubation method, adverse events during transport and transport outcome were retrieved.Results:Eighteen of the 21 patients were transferred under our mobile ECMO team from outer hospitals to our ECMO intensive care unit. Three patients were cannulated by physicians of outer hospital and transported to our ECMO intensive care unit. All patients were transported by ground ambulance, and the distances varied from 2.5 to 252 km, with an average distance of 112.3±103.2 km. No death occurred during transportation. Adverse events in transport occurred in 6 patients. Of these, the most common were patient-related adverse events..Conclusions:Inter-hospital transport by ECMO in China is currently dominated by ground ambulance.. Experienced mobile ECMO team can safely operate inter-hospital transport supported by ECMO
RESUMO
Objective:To explore the predictive factors of renal replacement therapy (RRT) in extracorporeal membrane oxygenation (ECMO) patients.Methods:The clinical data of 68 ECMO patients treated at Emergence Department of Jiangsu Provincial Hospital from January 2015 to December 2018 were retrospectively analyzed. Vasoactive-inotropic score (VIS) was used to assess the usage of vasoactive-inotropic drugs on day 1, 2 and 3 of ECMO (24 h VIS, 48 h VIS, and 72 h VIS). According to received RRT or not, patients were divided into the RRT group and non-RRT group. Age, gender, weight, VIS, presence of cardiac arrest before ECMO, ECMO mode, and ECMO treatment time were compared. Logistic regression analysis was used to identify predictive factors for RRT in ECMO patients.Results:Of the enrolled patients, 73.5% of ECMO patients received RRT. The mean age, 24 h VIS, ECMO failure and mortality of the RRT group were significantly higher than those of the non-RRT group ( P <0.05). The use of RRT was 87.8% in elderly ECMO patients (> cutoff age of 38.5 years). According to the cutoff value of 24 h VIS (33.75), ECMO patients were divided into the high VIS group and low VIS group. The rates of RRT and mortality were both exceeded 90% in the high VIS group, which was significantly higher than that of the low VIS group ( P <0.05). Logistic regression analysis showed that age ( OR=1.223) and 24 h VIS ( OR=1.033) were predictive factors of RRT in ECMO patients ( P <0.05). Conclusions:Age and 24 h VIS show the predictive value for RRT in ECMO patients.
RESUMO
Objective:To evaluate left ventricular systolic function (LVEF) after extracorporeal membrane oxygenation (ECMO) in patients with acute fulminant myocarditis (AFM).Methods:Seven patients were admitted in the First Affiliated Hospital of Nanjing Medical University from August 2018 to November 2018. All the patients accepted veno-arterial extracorporeal membrane oxygenation (V-AECMO). Complications associated with ECMO and clinical outcome were documented. Transthoracic echocardiography (TTE), single photo emission computed tomography (SPECT), and cardiac magnetic resonance (CMR)were performed to evaluate LVEF.Results:Seven patients were successfully weaned from V-AECMO, 2 of whom had oxygenator leakage, 4 had femoral artery bleeding after decannulation, and 2 had femoral artery pesudoaneurysm. There was no statistical difference in LVEF evaluation between TTE and CMR [(62.4±6.8)% vs (58.9±8.2)%, P >0.05]. CMR and SPECT further revealed myocardial pathological change and coronary arterial blood perfusion. Conclusions:ECMO is recommended in patients with AFM. TTE is simple and easy to perform and is not inferior to CMR in LVEF evaluation. CMR can reflect pathological changes of cardiomyocytes at the cellular level, and SPECT can reflect coronary perfusion.
RESUMO
Objective:To analyze the effect of troponin T decrease rate on the prognosis of patients with acute fulminant myocarditis (AFM) following extracorporeal membrane oxygenation (ECMO).Methods:AFM patients treated with ECMO from April 2015 to December 2018 in our hospital were enrolled in this study. According to the hospital survival, patients were divided into the survival group and non-survival group. The decrease rate of troponin T within 24, 48 and 72 h were compared in the two groups.Results:A total of 18 patients with a mean age of 31 years were enrolled. Fifteen patients survived and 3 patients died with an in-hospital survival rate of 83.3%. The decrease rate of troponin T within 24 h was higher in the survival group than that in the non-survival group (49.36% vs.-59.57%, P<0.05), while there were no statistical differences in 48 h and 72 h between the two groups (57.17% vs.-35.67%, 65.53% vs. 58.96%; all P>0.05). Conclusions:ECMO is an effective treatment for cardiogenic shock or cardiac arrest caused by AFM. The decrease rate of troponin T within 24 h supported by ECMO is higher in the survival group.
RESUMO
Objective:To identify the impact of extracorporeal cardiopulmonary resuscitation (ECPR) on neurological outcome and survival in adults with cardiac arrest (CA).Methods:Totally 31 adult patients with ECPR were enrolled from March 2015 to June 2019 in Emergency Department of the First Affiliated Hospital of Nangjing Medical University (Jiangsu People Hospital). Patients were divided to the survival group ( n=12) and death group ( n=19). Duration of conventional cardiopulmonary resuscitation (CCPR) and extracorporeal membrane oxygenation (ECMO) and other mechanical support were compared between groups. Cerebral performance category (CPC) and hospital survival were also evaluated according to the duration of CCPR before ECPR. Results:The duration of CCPR before ECPR was significantly shorter in the survival group than that in the death group ( P=0.002). Duration of ECMO had no significant difference between the two groups ( P=0.478). The location of CA occurrence had no impact on the hospital survival rate ( P=0.716). ECPR in combination with intra-aortic balloon pump (IABP) also had no impact on the hospital survival rate ( P=0.174), and patients received continuous renal replacement therapy (CRRT) had higher hospital survival than patients without CRRT ( P = 0.032). Patients with CCPR duration ≤ 60 min had higher rates of ROSC and hospital survival ( P <0.001). CPC evaluation showed no difference between the two groups. Conclusions:ECMO can provide effective life support to CA patients, and improve their survival rates. It is recommended to initiation of ECMO implantation within 60 min after CCPR.
RESUMO
Objective To determine the predictive values of different critical scoring systems for survival rate after discharge in critically ill patients supported by extracorporeal membrane oxygenation (ECMO). Methods The clinical data of 34 critically ill patients supported by ECMO admitted to Department of Emergency of the First Affiliated Hospital of Nanjing Medical University (Jiangsu Provincial People's Hospital) from July 2015 to September 2017 were retrospectively analyzed. The general information and the worst values of vital signs and related pathophysiological indicators within 12 hours before ECMO treatment of patients were collected, and sequential organ failure assessment (SOFA), multiple organs dysfunction score (MODS), simplified acute physiology score Ⅱ (SAPSⅡ), and acute physiology and chronic health evaluation Ⅳ(APACHEⅣ) scores were calculated. The patients were divided into survival group and non-survival group according to 28-day survival after hospital discharge. General clinical characteristics and aforementioned scores were compared between the two groups. Scoring systems for predicting prognosis were assessed by using the receiver operating characteristic (ROC) curve. The Kaplan-Meier method was used to depict the surviving curve. Results Thirty-four patients were finally enrolled, 13 of whom were dead at the follow-up period of 28 days after hospital discharge, and 21 survived. Duration of ECMO support in non-survival group was significantly shorter than that in survival group (hours: 101.4±7.8 vs. 134.4±12.6), SOFA, SAPSⅡ, and APACHEⅣ scores were significantly higher than those of survival group (SOFA score: 10.6±3.6 vs. 8.8±3.3, SAPSⅡscore: 38.7±14.3 vs. 31.8±12.5, APACHEⅣ score: 46.5±15.5 vs. 38.1±11.3, all P < 0.05). There was no significant difference in gender, age, body mass index (BMI), vital signs or related pathophysiological indicators within 12 hours before ECMO treatment, or MODS score between the two groups. ROC curve analysis showed that the area under ROC curve (AUC) of SAPSⅡ score for predicting 28-day survival rate was the highest, which was significantly higher than that of SOFA, MODS, and APACHEⅣ score (0.880 vs. 0.694, 0.654, 0.682, all P < 0.05). When the best cut-off value of SAPSⅡ score was 43, the sensitivity was 81.2%, and the specificity was 77.9%. Kaplan-Meier survival analysis showed that 28-day survival rate after hospital discharge in patients with SAPSⅡ score < 43 (n = 18) was significantly higher than that in patients with SAPSⅡ score ≥43 (n = 16; χ2= 2.444, P = 0.018). Conclusions Four critical scoring systems of SOFA, MODS, SAPSⅡand APACHEⅣ have been proved to have good prognostic ability to predict 28-day survival after hospital discharge in critically ill patients supported by ECMO. Among them, SAPSⅡ score system has more accurate prediction value.
