Background: Since the approval of oral factor Xa inhibitors, there have been concerns regarding ability to neutralize their anticoagulant effects after intracranial hemorrhage (ICH). Multiple guidelines suggest using prothrombin complex concentrates (PCCs) in these patients on basis research that includes a limited number with ICH. Given this, we aimed evaluate safety and efficacy PCCs for inhibitor–related ICH large, multicenter cohort patients. Methods: This was multicenter, retrospective,...

Background: Headache is a debilitating complication following an aneurysmal subarachnoid hemorrhage (aSAH). Despite its impact on morbidity and quality of life, limited evidence characterizes the effectiveness opioids. Objective: The aim this study was to evaluate opioid associated reduction in pain scores patients with aSAH-associated headache. Methods: This retrospective adult aSAH, Hunt Hess grades I – III, admitted neurosciences intensive care unit. Descriptive inferential statistics...

Cefoxitin is a second-generation cephamycin antibiotic, which at concentrations ≥100 µg/mL known to modestly interfere, for up 2 hours post-infusion, with serum creatinine measurement via the traditional Jaffe-based assay. We report case of severe elevation while utilizing cefoxitin as component an antimicrobial regimen in critically ill patient Mycobacterium abscessus ventriculomeningitis. Our results, both analysis and spiking experiment, demonstrate interference despite utilization...

Purpose: The objective of this study is to characterize opioid intensity in the intensive care unit (ICU) and its association with utilization across transitions. Methods: This a prospective cohort study. Medically ill ICU patients complete medication histories who survived discharge were included. Opioid was characterized based on IV morphine milligram equivalents (IV MME). Primary outcomes prescribing upon hospital discharge. Results: Opioids prescribed 34.1% 31.1% Within ≥50 mean MME/ICU...

Valproic acid (VPA) is a broad-spectrum anticonvulsant drug. Under normal conditions, this drug highly protein bound. However, in patients with hypoalbuminemia, the free fraction can increase substantially while total VPA levels remain therapeutic range. The neurologic activity and toxicity of are directly related to levels.Our in-house assay was validated using 20 patient samples obtained from reference laboratory (RL1). It further evaluated by parallel testing RL1 collected our patients....
