Abstract

Purpose: Target temperature management (TTM) and extracorporeal cardiopulmonary resuscitation (ECPR) have been established as important interventions during cardiopulmonary arrest. However, the impact of combined TTM and ECPR on clinical outcomes has not been studied in detail. Methods: We reviewed the records of 245 patients who received extracorporeal life support (ECLS) between January 2012 and June 2015. Exclusion criteria were as follows: Extracorporeal life support performed for reasons other than cardiac arrest, age less than 18 years, and death within 24 hours. A total of 101 patients were finally included in the study. Twenty-five patients underwent TTM, and 76 patients did not. Results: The patients' mean age was 55 ± 16.7 years. The mean cardiac arrest time was 44.6 ± 33.5 minutes. There were 84 patients whose cardiac arrest was due to a cardiac cause (83.2%) and 79 patients with in-hospital cardiac arrest (78.2%). There was a significant difference in average body temperature during the first 24 hours following ECPR (33.4°C vs 35.6°C; P =.001). The overall favorable neurological outcome rate was 34% and hospital survival rate was 47%. There was no difference in favorable neurological outcomes and hospital survival between the TTM and non-TTM groups (P =.91 and.84, respectively). On multivariate analysis of neurological outcomes and hospital survival, TTM was not a significant prognostic factor. Conclusion: We did not observe any benefits of TTM in patients undergoing ECPR. Natural hypothermia or normothermia related to ECLS may explain this result. Further research is needed to understand the role of TTM in ECPR. [ABSTRACT FROM AUTHOR]

Abstract

Background: Acute respiratory distress syndrome (ARDS) is potentially underrecognized by clinicians. Early recognition and subsequent optimal treatment of patients with ARDS may be facilitated by usage of biomarkers. Surfactant protein D (SP-D), a marker of alveolar epithelial injury, has been proposed as a potentially useful biomarker for diagnosis of ARDS in a few studies. We tried to validate the performance of plasma SP-D levels for diagnosis of ARDS.Methods: We conducted a retrospective analysis using data from three (two in USA and one in Korea) prospective biobank cohorts involving 407 critically ill patients admitted to medical intensive care unit (ICU). A propensity score matched analysis (patients with versus without ARDS, matched 1:1) was carried out using significant variables from multiple logistic regression. The diagnostic accuracy of plasma SP-D as a diagnostic marker of ARDS was assessed by receiver operating characteristic curve analysis.Results: Out of the 407 subjects included in this study, 39 (10%) patients fulfilled ARDS criteria. Patients with ARDS had higher SP-D levels in plasma (p < 0.01) and higher hospital-mortality (p < 0.001) than those without ARDS. Thirty eight subjects with ARDS (cases) were successfully matched for propensity for ARDS with 38 subjects without ARDS (controls). Plasma levels of SP-D were higher in cases with ARDS compared to their matched controls without ARDS [median 20.8 ng/mL (interquartile range, 12.7-38.4) versus 7.9 (4.1-17.0); p = 0.001]. The area under the receiver operating characteristic curve for SP-D for the diagnosis of ARDS was 0.71 (95% confidence intervals, 0.60-0.83). A cut-off point of 12.7 ng/mL for SP-D yielded sensitivity of 74% and specificity of 63%.Conclusions: High levels of SP-D within 48 h after ICU admission might serve as a diagnostic marker for ARDS in patients hospitalized in medical ICU. Further prospective trials are required to validate the diagnostic role of SP-D in ARDS, and if its usefulness is greater in direct than in indirect ARDS, as well as across different strata of severity of ARDS.

Abstract

ECMO use has increased lately. However, differences between adult ECMO and non-ECMO patients admitted to the ICU remain unstudied. In terms of volume-outcome relationship, the impact of ECMO volume on survival has not been validated in a real world cohort.

Abstract

Background: Limited data are available on imaging predictors of neurological outcomes after extracorporeal cardiopulmonary resuscitation (ECPR). We investigated the association of initial brain computed tomography (CT) findings with neurological outcomes following ECPR.Methods: Between February 2005 and December 2015, a total of 42 patients who underwent brain CT scans within 48 h after ECPR were analyzed. Loss of the boundary between gray matter and white matter (LOB) or cortical sulcal effacement (SE), gray-to-white matter ratio (GWR), and optic nerve sheath diameter (ONSD) were measured on initial brain CT. The primary outcome was the Cerebral Performance Categories (CPC) scale at discharge.Results: Of the 42 adult ECPR patients, 23 (54.8%) patients survived to discharge and 19 (45.2%) patients had good neurological outcomes (CPC 1 and 2). The area under the curve (AUC) of GWR in the basal ganglia (GWR-BG) was 0.792 (95% confidence interval (CI), 0.639-0.901, p = 0.001). ONSD (AUC 0.745; 95% CI, 0.587 - 0.867, p = 0.007) was 5.57 (interquartile range (IQR) 5.14 - 5.98) mm in the good neurological outcome group versus 6.07 (IQR 5.71 - 6.64) mm in the poor outcome group. LOB or SE were more often detected in the poor neurological outcome group (AUC 0.817; 95% CI, 0.682-0.952, p <0.001). The predictive performance of poor neurological outcomes of a composite of GWR-BG, ONSD, and LOB/SE was significantly improved (AUC 0.904; 95% CI, 0.773-0.973) compared to when each brain CT marker was considered separately (GWR-BG, p = 0.048; ONSD, p = 0.026; LOB/SE, p = 0.028).Conclusions: GWR, ONSD, and LOB/SE on initial brain CT scans are associated with neurological prognosis in patients who underwent ECPR. The new risk prediction model, which uses a composite of GWR, ONCD, and LOB/SE, could provide better information on neurologic outcomes in patients underwent ECPR. [ABSTRACT FROM AUTHOR]
