Randomized Controlled Trial
Laser guidance for ultrasound-guided radial artery catheterization using smart glasses: a randomized trial.
The use of smart glasses during ultrasound-guided needle procedures may reduce operators' head movements but has not been shown to improve procedural performance. Laser guidance has been shown to decrease the time required for ultrasound-guided procedures in phantom models but has not been tested clinically. We hypothesized that adding laser guidance to the use of smart glasses for ultrasound-guided radial artery catheterization using the long axis approach would improve performance by relatively inexperienced users unfamilar with these techniques. ⋯ CRIS.nih.go.kr (KCT0007168); registered 8 April 2022.

Randomized controlled trials are one of the best ways of quantifying the effectiveness of medical interventions. Therefore, when the authors of a randomized superiority trial report that differences in the primary outcome between the intervention group and the control group are "significant" (i.e., P ≤ 0.05), we might assume that the intervention has an effect on the outcome. Similarly, when differences between the groups are "not significant," we might assume that the intervention does not have an effect on the outcome. ⋯ We calculate these metrics for four well-known multicentre trials. We provide links to online calculators so readers can easily estimate these metrics for published trials. In this way, we hope decisions on incorporating the results of randomized trials into clinical practice can be enhanced, minimizing the chance that useful treatments are discarded or that ineffective treatments are adopted.

To describe and review the experience of two pediatric intensive care units (PICUs) in Ontario, Canada, adapting and providing care to critically ill adults during the COVID-19 pandemic. ⋯ Though challenging, the experience has provided opportunity to enhance collaboration with partner institutions and improve the care of older children and adolescents in the PICU.

Limiting family presence runs counter to the family-centred values of Canadian pediatric intensive care units (PICUs). This study explores how implementing and enforcing COVID-19-related restricted family presence (RFP) policies impacted PICU clinicians nationally. ⋯ Pediatric intensive care unit-based RFP rules, largely designed and implemented without bedside clinician input, caused increased psychological burden for clinicians, characterized as moderate moral distress and trauma triggered by perceived impacts on families.
