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.

Observational Study
Orthostatic intolerance after acute mild hypovolemia: incidence, pathophysiologic hemodynamics, and heart-rate variability analysis-a prospective observational cohort study.
Early postoperative mobilization can be hindered by orthostatic intolerance (OI). Postoperative OI has multifactorial pathogenesis, possibly involving both postoperative hypovolemia and autonomic dysfunction. We aimed to investigate the effect of mild acute blood loss from blood donation simulating postoperative hypovolemia, on both autonomic function and OI, thus eliminating confounding perioperative factors such as inflammation, residual anesthesia, pain, and opioids. ⋯ ClinicalTrials.gov (NCT04499664); registered 5 August 2020.

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.

Randomized Controlled Trial
Comparison of the novel membrane-based carbon dioxide filter memsorb™ with a chemical granulate absorbent using a high-fidelity lung simulator: a prospective randomized in vitro trial.
Memsorb™ is a novel device for carbon dioxide (CO2) removal from anesthesia circuits via a semipermeable polymeric membrane. We evaluated the performance of the memsorb device for the removal of CO2 in an Aisys™ CS2 machine and compared it with a standard chemical granulate absorber (CGA) using a high-fidelity lung simulator. ⋯ CO2 was successfully removed from the anesthesia circuit. FICO2 was significantly higher with memsorb throughout the observation period. Nevertheless, the clinical impact of these observations remains unclear. Further clinical trials are required to determine the utility of the novel device.

Randomized Controlled Trial
Effect of early oral carbohydrate intake after elective Cesarean delivery on maternal body temperature and satisfaction: a randomized controlled trial.
Although the Enhanced Recovery After Cesarean Delivery (ERAC) consensus statement provides recommendations for early postoperative drinking and eating, evidence from high-quality clinical research directly addressing parturients is sparse. Our objective was to assess if early oral carbohydrate intake after elective Cesarean delivery improves maternal recovery. ⋯ www.chictr.org.cn (ChiCTR2000031085); first submitted 13 November 2022.
