Medical students do not adversely affect the quality of cardiopulmonary resuscitation for ED patients

Contemporary uses of trauma video review: a scoping review

OBJECTIVES

Trauma resuscitations are sporadic, high-acuity situations and conducting observation in the trauma bay for the purpose of quality improvement is challenging. We aim to review contemporary uses of trauma video review.

METHODS

Medline and Embase were searched from 1980 to May 2020 for studies involving trauma video review. English studies of adult and paediatric populations were included for study and analysed for uses of trauma video review, outcomes measured and any resulting quality improvement (QI) initiatives.

RESULTS

A total of 463 publications were identified with 21 studies meeting eligibility for final inclusion. A majority of studies (11) observed technical skills with analysis of critical procedures, including tracheal intubation and thoracotomy. The remaining studies observed team dynamics and communication. Overall, eight studies resulted in new policies being put in place for trauma resuscitations and six studies utilized trauma video review as an educational tool.

CONCLUSIONS

This study highlights common uses of trauma video review. The greatest benefit for this new technology is in quality improvement and education. The majority of studies focussed on critical procedures and QI initiatives, such as checklists, protocols and continued education. We recommend adoption of video review systems for ongoing improvement of team dynamics and overall trauma and emergency resuscitation.

Effect of flashlight guidance on manual ventilation performance in cardiopulmonary resuscitation: A randomized controlled simulation study

Several auditory-based feedback devices have been developed to improve the quality of ventilation performance during cardiopulmonary resuscitation (CPR), but their effectiveness has not been proven in actual CPR situations. In the present study, we investigated the effectiveness of visual flashlight guidance in maintaining high-quality ventilation performance. We conducted a simulation-based, randomized, parallel trial including 121 senior medical students. All participants were randomized to perform ventilation during 2 minutes of CPR with or without flashlight guidance. For each participant, we measured mean ventilation rate as a primary outcome and ventilation volume, inspiration velocity, and ventilation interval as secondary outcomes using a computerized device system. Mean ventilation rate did not significantly differ between flashlight guidance and control groups (P = 0.159), but participants in the flashlight guidance group exhibited significantly less variation in ventilation rate than participants in the control group (P<0.001). Ventilation interval was also more regular among participants in the flashlight guidance group. Our results demonstrate that flashlight guidance is effective in maintaining a constant ventilation rate and interval. If confirmed by further studies in clinical practice, flashlight guidance could be expected to improve the quality of ventilation performed during CPR.
