RESUMEN

Background: Septic shock is commonly treated in the emergency department (ED) with vasopressors. Prior data have shown that vasopressor administration through a peripheral intravenous line (PIV) is feasible. Objectives: To characterize vasopressor administration for patients presenting to an academic ED in septic shock. Materials and methods: Retrospective observational cohort study evaluating initial vasopressor administration for septic shock. ED patients from June 2018 to May 2019 were screened. Exclusion criteria included other shock states, hospital transfers, or heart failure history. Patient demographics, vasopressor data, and length of stay (LOS) were collected. Cases were grouped by initiation site: PIV, ED placed central line (ED-CVL), or tunneled port/indwelling central line (Prior-CVL). Results: Of the 136 patients identified, 69 were included. Vasopressors were initiated via PIV in 49%, ED-CVL in 25%, and prior-CVL in 26%. The time to initiation was 214.8 minutes in PIV and 294.7 minutes in ED-CVL (p = 0.240). Norepinephrine predominated all groups. No extravasation or ischemic complications were identified with PIV vasopressor administration. Twenty-eight-day mortality was 20.6% for PIV, 17.6% for ED-CVL, and 61.1% for prior-CVL. Of 28-day survivors, ICU LOS was 4.44 for PIV and 4.86 for ED-CVL (p = 0.687), while vasopressor days were 2.26 for PIV and 3.14 for ED-CVL (p = 0.050). Conclusion: Vasopressors are being administered via PIVs for ED septic shock patients. Norepinephrine comprised the majority of initial PIV vasopressor administration. There were no documented episodes of extravasation or ischemia. Further studies should look at the duration of PIV administration with potential avoidance of central venous cannulation altogether in appropriate patients.

RESUMEN

RATIONALE AND OBJECTIVES: Little is known about the frequency and risk factors of hepatic steatosis in the tertiary care setting. Such knowledge is essential to clinicians making decisions about testing for this condition. Thus, our aim was to describe the epidemiology of hepatic steatosis, as captured by magnetic resonance imaging (MRI), at a tertiary care center. MATERIALS AND METHODS: A near-consecutive cohort of 1006 adult patients underwent standard-of-care liver MRIs. Images were retrospectively processed to derive proton density fat fraction (PDFF) maps. Data from three spatially distinct regions of interest (ROIs) were aggregated to derive overall hepatic PDFF values. Demographic, anthropometric, clinical, and laboratory variables were included in a multivariate analysis to determine predictors of hepatic steatosis grades (based on established PDFF cutoffs). Hepatic steatosis grades derived from single vs aggregated ROIs were compared. RESULTS: Hepatic steatosis was observed in 25% of patients (19% grade 1; 3% grade 2; 3% grade 3). Controlling for all other variables, the odds of hepatic steatosis increased by 7%-9% (P <.001) for each whole point increase in body mass index (BMI), whereas elevated serum bilirubin was associated with lower odds of hepatic steatosis (P = .002). Race, diabetes mellitus, dyslipidemia, and metabolic syndrome were not independently predictive of hepatic steatosis when controlling for other variables (eg, BMI). Employing single ROIs (rather than three aggregated ROIs) resulted in incorrect steatosis grading in up to 8.0% of patients. CONCLUSION: Many adult patients undergoing liver MRI at a tertiary care center have hepatic steatosis, with larger BMIs as the only independent predictor of higher grades. This information can be used by clinicians at such centers to make evidence-based decisions about when to test for hepatic steatosis in their patients.
