Covid-19 pandemic in ICU. Limited resources for many patients: approaches and criteria for triaging.
The COVID-19 pandemic has shattered the illusion that healthcare resource shortages that require rationing are problems restricted to low- and middle-income countries. During the pandemic surges, many high-income countries have been confronted with unprecedented demands for healthcare systems that dramatically exceeded available resources. Hospitals capacities were overwhelmed, and physicians working in intensive care units (ICUs) were often forced to deny admissions to patients in desperate need of intensive care. ⋯ Thus far, however, consensus on the approaches used, and, above all, on the solutions adopted have been limited, giving rise to a clash of opinions that has further complicated health professionals' ability to respond optimally to their patients' needs. As the COVID-19 crisis moves toward a phase of what some have called "pandemic normalcy," the need to debate the merits and demerits of the individual decisions made in the allocation of ICU resources seems less pressing. Instead, the aims of the authors are: 1) to critically review the approaches and criteria used for triaging patients to be admitted in ICU; 2) to clarify how macro- and micro-allocation choices, in their interdependance, can condition decision-making processes regarding the care of individual patients; 3) to reflect on the need for decision-makers and professionals working in ICUs to maintain a proper degree of "honesty" towards citizens and patients regarding the causes of the resource shortages and the decision-making processes, which, in different ways routinely and in crisis times, involve the need to make "tragic choices" at both levels.

Comparison of two regional citrate anticoagulation modalities for continuous renal replacement therapy by a prospective analysis of safety, workload, effectiveness, and cost.
Currently, regional citrate anticoagulation (RCA) is the preferred approach for continuous renal replacement therapy (CRRT), and several RCA protocols are commercially available. This study was aimed at comparing two RCA modalities for CRRT in terms of safety, workload, effectiveness, and costs. ⋯ Pre-filter hypertonic sodium-citrate solution (136 mmol/L) results in longer filter patency and improves depuration effectiveness. However, compared to RCA-CVVHF, it causes metabolic alkalosis and increases nursing interventions and cost.

ReviewTier-three therapies for refractory intracranial hypertension in adult head trauma.
Refractory intracranial hypertension after traumatic brain injury (TBI) is defined as recurrent increase of intracranial pressure above 20-22 mmHg for sustained period of time (10-15 min), despite conventional therapies, such as osmotic therapy, cerebral spinal fluid drainage and mild hyperventilation. As such, more aggressive treatments should be taken into consideration. In particular, therapeutic hypothermia, barbiturates administration and decompressive craniectomy are considered as tier-three or "salvage" interventions, as they have shown to be able to control refractory hypertension; however, they are also associated with an increased risk of significant side effects. Therefore, the aim of this review was to describe the evidence supporting the use of these tier-three therapies in the management of refractory intracranial hypertension in TBI patients.
