Background: Since the approval of the oral factor Xa inhibitors, there have been concerns regarding the ability to neutralize their anticoagulant effects after intracranial hemorrhage (ICH). Multiple guidelines suggest using prothrombin complex concentrates (PCCs) in these patients on the basis of research that includes a limited number of patients with ICH. Given this, we aimed to evaluate the safety and efficacy of PCCs for factor Xa inhibitor-related ICH in a large, multicenter cohort of patients.Methods: This was a multicenter, retrospective, observational cohort study of patients with apixaban- or rivaroxaban-related ICH who received PCCs between January 1, 2015, and March 1, 2019. The study had 2 primary analysis groups: safety and hemostatic efficacy. The safety analysis evaluated all patients meeting inclusion criteria for the occurrence of a thrombotic event, which were censored at hospital discharge or 30 days after PCC administration. Patients with intracerebral, subarachnoid, or subdural hemorrhages who had at least 1 follow-up image within 24 hours of PCC administration were assessed for hemostatic efficacy. The primary efficacy outcome was the percentage of patients with excellent or good hemostasis on the basis of the modified Sarode criteria. Secondary outcomes included an evaluation of in-hospital mortality, length of stay, infusion-related reactions, and thrombotic event occurrence during multiple predefined periods.Results: A total of 663 patients were included and assessed for safety outcomes. Of these, 433 patients met criteria for hemostatic efficacy evaluation. We observed excellent or good hemostasis in 354 patients (81.8% [95% CI, 77.9-85.2]). Twenty-five (3.8%) patients had a total of 26 thrombotic events, of which 22 occurred in the first 14 days after PCC administration. One patient had documentation of an infusion-related reaction. For the full cohort of patients, in-hospital mortality was 19.0%, and the median intensive care unit and hospital lengths of stay were 2.0 and 6.0 days, respectively.Conclusions: Administration of PCCs after apixaban- and rivaroxaban-related ICH provided a high rate of excellent or good hemostasis (81.8%) coupled with a 3.8% thrombosis rate. Randomized, controlled trials evaluating the clinical efficacy of PCCs in patients with factor Xa inhibitor-related ICH are needed. [ABSTRACT FROM AUTHOR]

Objectives: Hyperchloremia has been associated with increased morbidity and mortality in critically ill patients. While previous research has demonstrated an association between hypertonic saline and hyperchloremia, limited data exist in neurocritical care patients. The objective of this study is to determine the impact of moderate hyperchloremia (chloride ≥ 115 mmol/L) on clinical outcomes in intracerebral hemorrhage patients treated with continuous IV infusion 3% hypertonic saline.Design: Multicenter, retrospective, propensity-matched cohort study.Setting: Neurocritical care units at two academic medical centers with dedicated neurocritical care teams and comprehensive stroke center designation.Patients: Intracerebral hemorrhage patients discharged between September 2011 and September 2015 were evaluated and matched 1:1 based on propensity scoring.Interventions: Continuous IV infusion 3% hypertonic saline.Measurements and Main Results: A total of 219 patients were included in the unmatched cohort (143 moderate hyperchloremia and 76 nonhyperchloremia) and 100 patients in the propensity-matched cohort. In-hospital mortality was significantly higher in those who developed moderate hyperchloremia in a propensity-matched cohort (34% vs 14%; p = 0.02). Moderate hyperchloremia independently predicted in-hospital mortality in multivariable logistic regression analysis (odds ratio, 4.4 [95% CI, 1.4-13.5]; p = 0.01).Conclusions: We observed higher rates of in-hospital mortality in patients who developed moderate hyperchloremia during treatment with continuous IV infusion 3% hypertonic saline, with moderate hyperchloremia independently predicting in-hospital mortality. These results suggest that chloride values should be monitored closely during hypertonic saline treatment as moderate elevations may impact outcomes in intracerebral hemorrhage patients.
