Management of intracranial hemorrhage in adult patients on extracorporeal membrane oxygenation (ECMO): An observational cohort study.

ABSTRACT: Intracranial hemorrhage (ICH) is a common complication in adults treated with extracorporeal membrane oxygenation (ECMO). The aim of this study was to identify predictors of outcome and investigate intervention strategies following ICH development in ECMO-treated adult patients.We conducted a retrospective review of adult patients (?18 years) who developed an ICH during ECMO treatment at the Karolinska University Hospital (Stockholm, Sweden) between September 2005 and May 2017. Outcome was assessed by 30-day mortality and Glasgow Outcome Scale (GOS) after 6 months. The statistical analysis was supplemented by a case series of patients who were surgically treated for an ICH.Sixty-five patients developed an ICH during ECMO treatment. 30-day mortality was 74% (n = 48), and was significantly associated with low level of consciousness at ICH diagnosis (p = 0.036), presence of intraparenchymal hematoma (IPH) (p = 0.049), IPH volume (p = 0.002), presence of intraventricular hemorrhage (p = 0.001), subarachnoid hemorrhage Fisher grade (p<0.001), hydrocephalus (p<0.001), midline shift (p = 0.026) and absent basal cisterns (p<0.001). Among the 30-day survivors (n = 17), 63% (n = 10) had favorable neurological outcome (GOS 4-5) after six months. Five patients were surgically treated for their ICH, some with dire hemorrhagic consequences, however one patient made a complete recovery.ICH in adult ECMO patients is associated with a high mortality rate. Outcome predictors can help to identify patients where ICH treatment is indicated. Treating a patient with an ICH during ECMO represents an intricate balance between pro- and anticoagulatory demands. Furthermore, surgical treatment is associated with several risks but may be indicated in life-threatening lesions. Prospective studies are warranted.

Project description:BackgroundIntracranial hemorrhage (ICH) is a recognized complication of adults treated with extracorporeal membrane oxygenation (ECMO) and is associated with increased morbidity and mortality. However, the predictors of ICH in this patient category are poorly understood. The purpose of this study was to identify predictors of ICH in ECMO-treated adult patients.MethodsWe conducted a retrospective review of adult patients (?18 years) treated with ECMO at the Karolinska University Hospital (Stockholm, Sweden) between September 2005 and June 2016, excluding patients with ICH upon admission or those who were treated with ECMO for less than 12 h. In a comparative analysis, the primary end-points were the difference in baseline characteristics and predictors of hemorrhage occurrence (ICH vs. non-ICH cohorts). The secondary end-point was difference in mortality between groups. Paired testing and uni- and multivariate regression models were applied.ResultsTwo hundred and fifty-three patients were included, of which 54 (21%) experienced an ICH during ECMO treatment. The mortality for patients with ICH was 81% at 1 month and 85% at 6 months, respectively, compared to 28 and 33% in patients who did not develop ICH. When comparing ICH vs. non-ICH cohorts, pre-admission antithrombotic therapy (p?=?0.018), high pre-cannulation Sepsis-related Organ Failure Assessment (SOFA) coagulation score (p?=?0.015), low platelet count (p?<?0.001), and spontaneous extracranial hemorrhage (p?=?0.045) were predictors of ICH. In a multivariate regression model predicting ICH, pre-admission antithrombotic therapy and low platelet count demonstrated independent risk association. When comparing the temporal trajectories for coagulation variables in the days leading up to the detection of an ICH, plasma antithrombin significantly increased per patient over time (p?=?0.014). No other temporal trajectories were found.ConclusionsICH in adult ECMO patients is associated with a high mortality rate and independently associated with pre-admission antithrombotic therapy and low platelet count, thus highlighting important areas of potential treatment strategies to prevent ICH development.
