Background: The effectiveness of head mounted real-time ultrasound displays (hereafter referred to as 'smart glasses') in improving hand-eye coordination in less experienced individuals, such as trainees in anaesthesia, is unclear.

Objectives: To compare the first-attempt success rate of smart glasses-assisted ultrasound-guided paediatric radial artery catheterisation with conventional ultrasound guided catheterisation performed by anaesthesiology trainees.

Design: Prospective randomised controlled trial.

Settings: Tertiary university hospital from September 2021 to February 2023.

Patients: One hundred and twenty-two paediatric patients (age <7 years, weight ≥3 kg) who required radial artery cannulation during general anaesthesia.

Interventions: The participants were randomly assigned to either the ultrasound screen group (control) or the smart glasses group prior to radial artery catheterisation.

Main outcome measures: The primary outcome was the first attempt success rate. Secondary outcomes included the number of attempts, use of transfixion technique, overall complication rate, and clinical anaesthesiology (CA) year of the operators.

Results: A total of 119 paediatric patients were included in the analysis. The smart glasses group exhibited higher first-attempt success rate than did the control group (89.8% [53/59] vs. 71.7% [43/60]; P  = 0.023; odds ratio (OR) 3.49; (95% confidence interval (CI) 1.27-9.6). The overall number of attempts [median, 1; interquartile range (IQR), 1-1; range, 1-3 vs. median, 1; IQR, 1-2; range, 1-4; P   =  0.006], use of transfixion technique (12/59 [20.3%] vs. 28/60 [46.7%]; P  = 0.002), and overall complication rate (6.8% [4/59] vs. 30.0% [18/60]; P  = 0.002) were lower in the smart glasses group than in the control group. However, among paediatric anaesthesiology fellows (CA 5 years), the first- (89.3% [25/28] vs. 80.8% [21/26]; P  = 0.619) and second-attempt success rates (96.4% [27/28] vs. 80.8% [21/26]; P  = 0.163) did not differ between the two groups.

Conclusions: Smart glasses-assisted ultrasound guided radial artery catheterisation improved the first attempt success rate among anaesthesiology trainees, reducing the number of attempts and overall complication rates in small paediatric patients. Smart glasses were more effective for anaesthesia residents (CA 2-4 years) but were not effective for paediatric anaesthesiology fellows (CA 5 years).

Background: Opioids play an important role in peri-operative pain management. However, opioid use is challenging for healthcare practitioners and patients because of concerns related to opioid crises, addiction and side effects.

Objective: This review aimed to identify and synthesise the existing evidence related to adults' experiences of opioid use in postoperative pain management.

Design: Systematic scoping review of qualitative studies. Inductive content analysis and the Theoretical Domains Framework (TDF) were applied to analyse and report the findings and to identify unexplored gaps in the literature.

Data sources: Ovid MEDLINE, PsycInfo, Embase, CINAHL (EBSCO), Cochrane Library and Google Scholar.

Eligibility criteria: All qualitative and mixed-method studies, in English, that not only used a qualitative approach that explored adults' opinions or concerns about opioids and/or opioid reduction, and adults' experience related to opioid use for postoperative pain control, including satisfaction, but also aspects of overall quality of a person's life (physical, mental and social well being).

Results: Ten studies were included; nine were qualitative ( n  = 9) and one used mixed methods. The studies were primarily conducted in Europe and North America. Concerns about opioid dependence, adverse effects, stigmatisation, gender roles, trust and shared decision-making between clinicians and patients appeared repeatedly throughout the studies. The TDF analysis showed that many peri-operative factors formed people's perceptions and experiences of opioids, driven by the following eight domains: Knowledge, Emotion, Beliefs about consequences, Beliefs about capabilities, Self-confidence, Environmental Context and Resources, Social influences and Decision Processes/Goals. Adults have diverse pain management goals, which can be categorised as proactive and positive goals, such as individualised pain management care, as well as avoidance goals, aimed at sidestepping issues such as addiction and opioid-related side effects.

Conclusion: It is desirable to understand the complexity of adults' experiences of pain management especially with opioid use and to support adults in achieving their pain management goals by implementing an individualised approach, effective communication and patient-clinician relationships. However, there is a dearth of studies that examine patients' experiences of postoperative opioid use and their involvement in opioid usage decision-making. A summary is provided regarding adults' experiences of peri-operative opioid use, which may inform future researchers, healthcare providers and guideline development by considering these factors when improving patient care and experiences.
