ObjectiveTo find out the possible factors that may affect the survival time of patients undergoing return of spontaneous circulation (ROSC) within seven days of cardio-pulmonary resuscitation. MethodWe retrospectively collected 20 clinical indicators from 51 patients who underwent ROSC after cardio-pulmonary resuscitation in Emergency Department between August 2013 and February 2015. The indicators included gender, age, duration of cardio-pulmonary resuscitation, blood pressure acquired immediately after ROSC, heart rate, respiration, lactic acid, creatinine, prothrombin time, bilirubin, pH, arterial partial pressure of carbon dioxide, potassium, sodium, blood glucose, atrial natriuretic peptides, leukocyte, platelets, and hemoglobin. Then we analyzed the correlation of these indicators with survival time through Cox regression model. ResultsThe results showed that duration of cardiopulmonary resuscitation[RR=1.053, 95% CI (1.020, 1.088), P=0.002] and systolic blood pressure acquired immediately after ROSC[RR=0.991, 95% CI (0.982, 0.999), P=0.038] significantly affected the survival time of patients after ROSC. ConclusionsDuration of cardiopulmonary resuscitation and systolic blood pressure acquired immediately after ROSC may be useful in predicting the survival time of patients after ROSC.
Objective To describe the clinical profiles of cardiac arrest due to fatal pulmonary embolism (FPE), and review the literature on FPE diagnosis and treatment. Methods The clinical profiles of two cases with cardiac arrest for FPE were presented. A systematic search of Medline (1950 - 2014) and EMbase (1980-2014) was conducted to identify studies that investigated the use of thrombolytic medications to treat cardiac arrest for FPE. Results The fatal event of two patients occurred after surgery. Both of them survived with cardiopulmonary resuscitation and administration of thrombolysis and anticoagulation, but one of them had major bleeding during anticoagulation. Six articles were found involving 72473 cases of cardiac arrest due to pulmonary embolism (PE) or unstable massive PE. The thrombolytic agents were recombinant tissue plasminogen activator or streptokinase, but the administration and dose of thrombolytic agents were unclear. Overall, administration of thrombolytics can shorten the time to return of spontaneous circulation and improve the survival rate. There was, however, an increased risk of bleeding events following administration of thrombolytics. Conclusions Because of the high mortality of cardiac arrest for FPE, the clinician should correctly identify patients with a high likelihood of FPE. Early use of thrombolytics is very important and can potentially improve patient outcomes.
ObjectiveTo explore the value of platelet-lymphocyte ratio (PLR) after return of spontaneous circulation (ROSC) combined with Sequential Organ Failure Assessment (SOFA) for estimating the short-term prognosis of ROSC patients suffered from in-hospital cardiac arrest (IHCA).MethodsROSC adult patients who suffered from IHCA during treatment in the Emergency Department of West China Hospital of Sichuan University between 00:00, August 1st, 2010 and 23:59, July 31st, 2018 were included retrospectively. The basic and clinical data of patients were collected. Patients were divided into survival group and death group according to the 28-day prognosis. Through logistic regression and receiver operating characteristic (ROC) curve analysis, the efficacy of PLR after ROSC combined with SOFA score in predicting the 28-day prognosis of IHCA patients was explored.ResultsA total of 199 patients were included, including 135 males and 64 females, with a mean age of (60.45±17.52) years old. There were 154 deaths and 45 survivors within 28 days. There were statistically significant differences between the survival group and the death group in terms of epinephrine dosage, SOFA score, proportion of patients complicated with respiratory diseases, and post-ROSC laboratory indexes including PLR, hemoglobin, red blood cell count, lymphocyte count, indirect bilirubin, serum albumin, cholesterol, and activated partial thrombin time (P<0.05). The result of multivariate logistic regression analysis showed that epinephrine dosage [odds ratio (OR)=1.177, 95% confidence interval (CI) (1.024, 1.352), P=0.022], SOFA score [OR=1.536, 95%CI (1.173, 2.010), P=0.002], PLR after ROSC [OR=1.011, 95%CI (1.004, 1.018), P=0.002] were independent risk factors for ROSC patients’ death on day 28. The areas under the ROC curve of epinephrine dosage, SOFA score and PLR after ROSC were 0.702, 0.703 and 0.737, respectively, to predict the patients’ 28-day outcome. Combining the epinephrine dosage and PLR after ROSC with SOFA score respectively to predict the 28-day outcome of patients, the areas under the ROC curve were 0.768 and 0.813, respectively.ConclusionsThe significant increase of PLR after ROSC is an independent risk factor for death within 28 days after ROSC. The combined application of PLR after ROSC and SOFA score in the 28-day outcome prediction of patients has better predictive efficacy.
