Red cell physiology and signaling relevant to the critical care setting
Purpose of review: Oxygen (O2) delivery, the maintenance of which is fundamental to supporting those with critical illness, is a function of blood O2 content and flow. Here, we review red blood cell (RBC) physiology relevant to disordered O2 delivery in the critically ill. Recent findings: Flow (rather than content) is the focus of O2 delivery regulation. O2 content is relatively fixed, whereas flow fluctuates by several orders of magnitude. Thus, blood flow volume and distribution vary to maintain coupling between O2 delivery and demand. The trapping, processing and delivery of nitric oxide (NO) by RBCs has emerged as a c...

How useful is extravascular lung water measurement in managing lung injury in intensive care unit ?
Conclusions: EVLWI and PVPI may have a prognostic significance in the assessment of lung injury in septic shock patients with ARDS. Further research is required to reveal the usefulness of EVLWI as an end point of fluid resuscitation in the management of septic shock with ARDS.

Risk Factors for Hospital-Acquired Pressure Injury in Surgical Critical Care Patients.
CONCLUSIONS: The strongest predictor was irritated skin, a potentially modifiable risk factor. Irritated skin should be treated and closely monitored, and the cause should be eliminated to allow the skin to heal. PMID: 33130863 [PubMed - in process]

Identifying Risk Factors for Pressure Injury in Adult Critical Care Patients.
CONCLUSION: Determining pressure injury risk in critically ill patients is complex and challenging. One common pathophysiological factor is impaired tissue oxygenation and perfusion, which may be nonmodifiable. Improved risk quantification is needed and may be realized in the near future by leveraging the clinical information available in the electronic medical record through the power of predictive analytics.

Management of Pediatric Severe Traumatic Brain Injury: 2019 Consensus and Guidelines-Based Algorithm for First and Second Tier Therapies
Conclusions: This article provides an algorithm of clinical practice for the bedside practitioner based on the available evidence, treatment protocols described in the articles included in the 2019 guidelines, and consensus that reflects a logical approach to mitigate intracranial hypertension, optimize cerebral perfusion, and improve outcomes in the setting of pediatric severe traumatic brain injury.

An International Survey of Corticosteroid Use for the Management of Low Cardiac Output Syndrome*
Conclusions: Our survey demonstrates considerable practice variability with regard to the type of patients in whom corticosteroids are administered, adrenal axis testing is performed, and dosage of hydrocortisone used. The majority of physicians, however, stated their willingness to randomize patients with severe low cardiac output syndrome in a corticosteroids trial. This survey identified multiple areas for future research on use of corticosteroids for low cardiac output syndrome.

Critical Care Compendium update
LITFL’s Critical Care Compendium is a comprehensive collection of pages concisely covering the core topics and controversies of critical care. Currently there are almost 1,500 entries with more in the works… Some pages are more developed than others, and all the pages are being constantly revised and improved. Links to new references and online resources are added daily, with an emphasis on those that are free and open access (FOAM!). These pages originated from the FCICM exam study notes created by Dr Jeremy Fernando in 2011, and have been updated, modified and added to since. As such will be particularly us...

Cerebrovascular Pressure Reactivity in Children With Traumatic Brain Injury*
Conclusions: In pediatric patients with traumatic brain injury, pressure-reactivity index has prognostic value and can identify cerebral perfusion pressure targets that may differ from treatment protocols. Our results suggest but do not confirm that cerebral perfusion pressure targeting using pressure-reactivity index as a guide may positively impact on outcome. This question should be addressed by a prospective clinical study.

Evaluation of Endotoxemia After Pediatric Cardiac Surgery With the Endotoxin Activity Assay: An Exploratory Prospective Cohort Study
Objective: Children with congenital heart diseases undergoing surgery with cardiopulmonary bypass are exposed to a high risk of perioperative endotoxemia. The aim of our study was to prospectively evaluate endotoxin assay activity reference levels during the postoperative phase of infants undergoing cardiac surgery for congenital heart disease and to assess their association with perioperative variables and postoperative infections. Design: Prospective exploratory single-center cohort study. Setting: Tertiary pediatric cardiac ICU. Patients: Infants undergoing cardiac surgery with cardiopulmonary bypass were enrolled. E...

Intracranial Hypertension and Cerebral Hypoperfusion in Children With Severe Traumatic Brain Injury: Thresholds and Burden in Accidental and Abusive Insults
Conclusions: The duration of hours of intracranial pressure more than 20 mm Hg and cerebral perfusion pressure less than 45 mm Hg best discriminated poor outcome. As the number of hours with intracranial pressure more than 20 mm Hg increases by 1, the odds of a poor outcome increased by 4.6%. Although abusive head trauma was strongly associated with unfavorable outcome, intracranial pressure/cerebral perfusion pressure thresholds did not differ between accidental and abusive head trauma.

Cardiac Surgery–Associated Kidney Injury in Children and Renal Oximetry
Conclusions: Findings demonstrate that preoperative oxygen supply/demand balance is an important predictor of cardiac surgery–associated acute kidney injury, suggesting lower preoperative (and intraoperative) renal blood flow may be protective. There is not yet a definite link between remote ischemic preconditioning and prevention of cardiac surgery–associated acute kidney injury; however, renal protective effects of sublethal ischemia should continue to be explored.

Thermoregulate, autoregulate and ventilate: brain-directed critical care for pediatric cardiac arrest
Purpose of review: Cardiac arrest in childhood is associated with a high risk for mortality and poor long-term functional outcome. This review discusses the current evidence for neuroprotective therapies and goals for postarrest care in the context of the pathophysiology of hypoxic–ischemic injury, modalities for neurologic prognostication in these children and potential future monitoring paradigms for maximizing cerebral perfusion in the postarrest period. Recent findings: The recent publication of the in-hospital and out-of-hospital Therapeutic Hypothermia After Cardiac Arrest trials demonstrated a lack of statistical...
