Article Synopsis
- This study examined the effects of intravenous vitamin C on adults with sepsis in the ICU, comparing its impact to a placebo.
- Among 872 patients, those receiving vitamin C had a higher combined risk of death or persistent organ dysfunction at 28 days compared to the control group.
- The results indicated no significant improvement in outcomes for organ dysfunction, survival, or quality of life, leading to the conclusion that vitamin C may not be beneficial in this patient population.
Background: Appropriate training of health professionals has been recommended to increase organ donation rates. Some studies have shown insufficient knowledge among medical students. This survey aims to describe their knowledge and attitude toward organ donation (OD).

However, optimal mean arterial pressure (MAP) targets for vasopressor titration are unknown. The objective of the Optimal VAsopressor TitraTION in patients 65 years and older (OVATION-65) trial is to ascertain the effect of permissive hypotension (vasopressor titration to achieve MAP 60-65 mm Hg) versus usual care on biomarkers of organ injury in hypotensive patients aged ≥65 years.
View Article and Find Full Text PDFBackground: The optimal approach to titrate vasopressor therapy is unclear. Recent sepsis guidelines recommend a mean arterial pressure (MAP) target of 65 mmHg and higher for chronic hypertensive patients. As data emerge from clinical trials comparing blood pressure targets for vasopressor therapy, an accurate description of usual care is required to interpret study results.
View Article and Find Full Text PDFA case report, focused on vasopressor use and presented in this article, is likely to resonate with many critical care nurses. In this article the authors describe opportunities to enhance safety with vasopressor therapy. Specifically, the goal of improving communication among physicians, nurses, and pharmacists around desired endpoints for vasopressor therapy, triggers for reassessment of the therapeutic strategy and cause of the patient's shock was identified as an area for improvement.
