Introduction: Initial healthcare delivery after warfront injury is unpredictably challenging for military forces. As preparatory training, healthcare providers use simulation to improve their performance in stressful critical situations. This study investigated whether a digital CA held by the team leader improved performance in simulated combat casualty care.

Introduction: High-fidelity simulation is widely used in the ongoing education of caregivers. However, the complex high-stakes simulated crisis environment affects memorization. This study investigated whether participants would remember more key training messages 3 months after a simulated complex emergency situation if they had used a digital cognitive aid (CA) during the simulations.

Introduction: The French army has implemented an algorithm based on the acronym "MARCHE RYAN," each letter standing for a key action to complete in order to help first care providers during emergency casualty care. On the battlefield, the risk of error is increased, and the use of cognitive aids (CAs) might be helpful to avoid distraction. We investigated the effect of using a digital CA (MAX, for Medical Assistance eXpert) by combat casualty care providers on their technical and nontechnical performances during the early management of simulated war wounds, compared to their memory and training alone.

Background: High-fidelity simulation is known to improve participant learning and behavioral performance. Simulation scenarios generate stress that affects memory retention and may impact future performance. The authors hypothesized that more participants would recall three or more critical key messages at three months when a relaxation break was performed before debriefing of critical event scenarios.

Objectives: High-fidelity simulation (HFS) calls heavily upon cognitive capacities and generates stress and anxiety. The objectives of this prospective, observational study were to assess trait anxiety and fear of negative evaluation (FNE) in anaesthesiology and critical care residents and appraise their state anxiety levels and cardiovascular responses during HFS training sessions.

Subjects And Methods: First-year anaesthesiology and critical care residents completed the French-Canadian adaptation of the State-Trait Anxiety Inventory (IASTA Y-1: state anxiety, IASTA Y-2: trait anxiety) and the French adaptation of the Fear of Negative Evaluation Scale (FNE).

Background: Pupillary diameter (PD) monitoring and Analgesia Nociception Index (ANI) (Metrodoloris, Lille, France), an online wavelet transform-based heart rate variability index, have been used in the assessment of pain.

Objective: The aim of this study was to evaluate the capacity of pupillary reflex dilatation and ANI to provide early assessment of regional anesthesia (RA) success following skin incision in children anesthetised with sevoflurane.

Methods: A total of 58 children, eligible for RA, were included after sevoflurane induction.

Objective/aim: To assess the impact of sevoflurane and anesthesia-induced hypotension on cerebral blood flow (CBF) in children younger than 2 years.

Background: Inhalational induction with sevoflurane is the most commonly used technique in young children. However, the effect of sevoflurane on cerebral perfusion has been only studied in adults and children older than 1 year.

Graft survival is worse in recipient aged less than 5 years due to the greater risk of vascular thrombosis. Thrombosis may be prevented by the choice of the donor, method of surgery, perioperative hemodynamic optimisation and preventive anti-coagulation. Normal growth is a major objective of the management of transplanted children.

Heart beat rate and blood pressure, together with baroreflex sensitivity, have become important tools in assessing cardiac autonomic system control and in studying sympathovagal balance. These analyses are usually performed thanks to spectral indices computed from standard spectral analysis techniques. However, standard spectral analysis and its corresponding rigid band-pass filter formulation suffer from two major drawbacks.
