Safety and efficacy of vasopressor administration through midline catheters.
Vasopressors are commonly administered through Central Venous Catheters (CVCs) as it is considered unsafe to administer them via peripheral IVs, mainly due to the concern of local tissue injury. Unlike peripheral IVs, midline catheters provide a wider lumen with the catheter tip ending in a large peripheral vein. The use of vasopressors through midline catheters has not yet been evaluated. ⋯ Many medical centers are attempting to limit the use of central venous catheters (CVCs) to avoid central line-associated bloodstream infections (CLABSIs). This study demonstrates that midline catheters are a safe alternative to CVCs, for the safe and efficacious administration of vasopressors for prolonged periods of time.

ReviewThe effects of arterial CO2 on the injured brain: Two faces of the same coin.
Serum levels of carbon dioxide (CO2) closely regulate cerebral blood flow (CBF) and actively participate in different aspects of brain physiology such as hemodynamics, oxygenation, and metabolism. Fluctuations in the partial pressure of arterial CO2 (PaCO2) modify the aforementioned variables, and at the same time influence physiologic parameters in organs such as the lungs, heart, kidneys, and the gastrointestinal tract. In general, during acute brain injury (ABI), maintaining normal PaCO2 is the target to be achieved. ⋯ On the other hand, inducing hypercapnia could be beneficial when certain specific situations require increasing CBF. The evidence supporting this claim is very weak. This review attempts providing an update on the physiology of CO2, its risks, benefits, and potential utility in the neurocritical care setting.

Levetiracetam pharmacokinetics in critically ill patients undergoing renal replacement therapy.
To determine clearance of levetiracetam in patients requiring continuous renal replacement therapy (CRRT) or sustained low efficiency dialysis (SLED). ⋯ Levetiracetam clearance was substantial with both modalities under the operating conditions reported. There is the potential for subtherapeutic concentrations with current recommended dosing strategies that account only for kidney function and not these extracorporeal routes of elimination.

EditorialOn predictions in critical care: The individual prognostication fallacy in elderly patients.
Predicting the future course of critical conditions involves personal experience, heuristics and statistical models. Although these methods may perform well for some cases and population averages, they suffer from substantial shortcomings when applied to individual patients. ⋯ This notably applies to triage situations in response to a lack of healthcare resources. We will discuss these issues and argue that analysing longitudinal data obtained from time-limited trials in intensive care can provide a more robust approach to individual prognostication.

Epidemiology and outcomes of invasive mechanical ventilation without ICU admission in acute care hospitals in Texas: A population-based cohort study.
The high ICU bed capacity in the United States (US) allows ICU care of patients requiring invasive mechanical ventilation (IMV), absent public health crisis. The use of IMV without ICU admission (non-ICU) in acute care hospitals in the US and its impact on patients' outcomes were not examined. ⋯ Non-ICU IMV was provided in 1 in 30 IMV hospitalizations in acute care hospitals. Although non-ICU IMV hospitalizations were younger and healthier than those admitted to ICU, their hospital mortality was markedly higher.
