Development and Testing of a Hybrid Simulator for Emergent Umbilical Vein Catheter Insertion Simulation Training.

Introduction: Emergent umbilical venous catheter (eUVC) insertion is the recommended vascular access in neonatal resuscitation. Although the theoretical knowledge can be taught, existing models are either unrealistic (plastic) or train only the steps of the task. This study aimed to develop and test a hybrid simulator for eUVC insertion training that would be realistic, reproducible, easy to build, and inexpensive, thereby facilitating detailed learning of the procedure.

Morphodynamic study of the corona mortis using the SimLife technology.

Purpose: Open book pelvic ring fractures are potentially life-threatening, due to their instability and major hemorrhage risk. During the open reduction and internal fixation, the pelvic approach remains a technical challenge, as the surgeon wants to prevent any iatrogenic damage of the vascular loop located in the retro-pubic area called corona mortis (CMOR). Recently, the cadaver perfused SimLife technology has been developed to improve the surgeon training, out of the operating room.

Effect of real-time feedback device compared to use or non-use of a checklist performance aid on post-training performance and retention of infant cardiopulmonary resuscitation: A randomized simulation-based trial.

Introduction: This study aims to determine the best method for achieving optimal performance of pediatric cardiopulmonary resuscitation (CPR) during simulation-based training, whether with or without a performance aid.

Methods: In this randomized controlled study, 46 participants performed simulated CPR in pairs on a Resusci Baby QCPR™ mannequin, repeated after four weeks. All participants performed the first simulation without performance aids.

Toward Optimal Learning of the Gesture in Laparoscopic Surgery: Methodology and Performance.

Classical surgical education has to face both a forensic reality and a technical issue: to train a learner in more complex techniques in an increasingly short time. Moreover, surgical training is still based on an empirical hierarchical relationship in which learners must reproduce a sequence of actions in a situation of strong emotional pressure. However, the effectiveness of learning and its quality are linked to the emotional states in which learners find themselves.

Should we recommend occipital plate fixation using bicortical screws or inverted occipital hooks to optimize occipito-cervical junction fusion? A biomechanical study combining an experimental and analytical approach.

Background: Occipito-cervical fusion can be necessary in case of cranio-cervical junction instability. Proximal stabilisation is usually ensured by bi-cortical occipital screws implanted through one median or two lateral occipital plate(s). Bone thickness variability as well as the proximity of vasculo-nervous elements can induce substantial morbidity.

How tibial tubercle torsion impacts patellar stability: A biomechanics study.

Introduction: A new factor for patellofemoral instability-external torsion of the tibial tubercle-has recently been described. The primary aim of this biomechanics study was to analyze the consequences of internal torsion tibial tubercle osteotomy (TTO) on an experimentally unstable patella. We hypothesized that internal TTO can stabilize an experimental patellar instability.

Immersive simulation training at 6-week intervals for 1 year and multidisciplinary team performance scores: a randomized controlled trial of simulation training for life-threatening pediatric emergencies.

Objectives: To demonstrate an effect of 1 year of training using immersive simulations repeated every 6 weeks versus every 6 months to improve the performance of multidisciplinary teams (MDTs) working with children in lifethreatening situations.

Material And Methods: Randomized controlled trial in 12 MDTs of emergency responders in France. Each MDT consisted of 4 persons: a physician, a resident, a nurse, and the ambulance driver.

Biomechanical analysis of the thoracolumbar spine under physiological loadings: Experimental motion data corridors for validation of finite element models.

Biomechanical studies that involve normal, injured or stabilized human spines are sometimes difficult to perform on large samples due to limited access to cadaveric human spines and biological variability. Finite element models alleviate these limitations due to the possibility of reusing the same model, whereas cadaveric spines can be damaged during testing, or have their mechanicals behaviour modified by fatigue, permanent deformation or structural failure. Finite element models need to be validated with experimental data to make sure that they represent the complex mechanical and physiological behaviour of normal, injured and stabilized spinal segments.

Evaluation of stress patterns during simulated laparoscopy in residency.

Background: Laparoscopy simulation offers realistic complexity of tasks and required skills, and helps to develop competencies. However the relationship of stress to the experience has not been comprehensively explored. Objectives were: 1) to evaluate stress level before and during laparoscopy in surgery interns (PGY-1) and surgery residents (PGY-2); 2) to evaluate performance in simulated laparoscopy in both groups; 3) to study the correlation between stress pathways themselves and to study which factors mediate the relationship between stress and performance.

Randomized controlled trial of multidisciplinary team stress and performance in immersive simulation for management of infant in shock: study protocol.

Background: Human error and system failures continue to play a substantial role in adverse outcomes in healthcare. Simulation improves management of patients in critical condition, especially if it is undertaken by a multidisciplinary team. It covers technical skills (technical and therapeutic procedures) and non-technical skills, known as Crisis Resource Management.

Testing of a Complete Training Model for Chest Tube Insertion in Traumatic Pneumothorax.

Introduction: Chest tube insertion is a frequent procedure in cases of traumatic pneumothorax, but severe complications can occur if not well performed. Although simulation-based training in chest tube insertion has improved performance, an affordable and realistic model for surgical insertion of a chest tube is lacking.

Objective: The objective was to design a model for surgical chest tube insertion that would be realistic, affordable, and transportable and that would reflect all extrathoracic and intrathoracic steps of the procedure.

Reliability and validity of a new measurement of lumbar foraminal volume using a computed tomography.

Estimation of the risk factors for falls in the elderly: can meta-analysis provide a valid answer?

The objective of this study was to analyze whether a meta-analysis could allow us to draw useful conclusions about the risk factors for falls in the elderly. A systematic review was carried out of various databases and completed manually. To satisfy the inclusion criteria, an article had to examine a population of subjects aged over 60 years to pertain to falls occurring during daily living activities, and to involve observational or interventional studies.

Laxatives as a risk factor for iatrogenic falls in elderly subjects: myth or reality?

Background: The multifactorial nature of falls is well known, and several studies on falls in the elderly have reported that laxatives can be a risk factor, but without attempting to discuss possible mechanisms to explain this role.

Objective: We aimed to isolate studies in which the risk factors for falls in the elderly related to laxatives have been evaluated and to carry out a meta-analysis combining the results of all identified good-quality studies.

Methods: Systematic literature review using the keywords 'accidental fall/numerical data' and 'risk factors'.
