Effectiveness of near-infrared light devices for peripheral intravenous cannulation in children and adolescents: A meta-analysis of randomized controlled trials

OBJECTIVES

To examine the effectiveness of near-infrared light devices (NIR) on procedure time of successful cannulation, success rate at the first attempt, and pain scores among pediatric patients and explore potential covariates on the intervention effect.

BACKGROUND

Pediatric patients have encountered a high failure rate as compared with adult patients using traditional cannulation. NIR devices might help to access veins with an optimum viewing area and eliminate the number of attempts. However, methodological limitations and inconsistent results from previous reviews were found.

METHODS

A three-step comprehensive search was performed in nine databases. Meta-analysis, subgroup, and meta-regression analyses were conducted. Individual quality assessment and certainty of evidence were assessed using the Cochrane risk of bias tool and the Grading of Recommendations, Assessments, Development, and Evaluation criteria, respectively.

RESULTS

We included 18 randomized controlled trials (RCTs) with 5298 children and adolescents across nine countries. NIR light devices significantly reduce -29.43 s of procedure time and -0.47 attempts of peripheral intravenous cannulation compared with traditional methods. Subgroup analysis observed a significantly large effect size on procedure time using AccuVein with pre-procedure training at the clinics. However, NIR light devices do not significantly decrease the procedure time, first attempt success rate, and pain scores. Meta-regression identified sample size as a significant covariate that had an impact on the success rate at the first attempt.

CONCLUSIONS

The near-infrared light device can statistically significantly reduce the procedure time and the number of attempts. Given the low or very low certainty of the evidence, future well-designed RCTs are necessary.

Overground Robotic Exoskeleton Training for Patients With Stroke on Walking-Related Outcomes: A Systematic Review and Meta-analysis of Randomized Controlled Trials

OBJECTIVE

This review aims to evaluate the effectiveness of solely overground robotic exoskeleton (RE) training or overground RE training with conventional rehabilitation in improving walking ability, speed, and endurance among patients with stroke.

DATA SOURCES

Nine databases, 5 trial registries, gray literature, specified journals, and reference lists from inception until December 27, 2021.

STUDY SELECTION

Randomized controlled trials adopting overground robotic exoskeleton training for patients with any phases of stroke on walking-related outcomes were included.

DATA EXTRACTION

Two independent reviewers extracted items and performed risk of bias using the Cochrane Risk of Bias tool 1 and certainty of evidence using the Grades of Recommendation Assessment, Development, and Evaluation.

DATA SYNTHESIS

Twenty trials involving 758 participants across 11 countries were included in this review. The overall effect of overground robotic exoskeletons on walking ability at postintervention (d=0.21; 95% confidence interval [CI], 0.01, 0.42; Z=2.02; P=.04) and follow-up (d=0.37; 95% CI, 0.03, 0.71; Z=2.12; P=.03) and walking speed at postintervention (d=0.23; 95% CI, 0.01, 0.46; Z=2.01; P=.04) showed significant improvement compared with conventional rehabilitation. Subgroup analyses suggested that RE training should combine with conventional rehabilitation. A preferable gait training regime is <4 times per week over ≥6 weeks for ≤30 minutes per session among patients with chronic stroke and ambulatory status of independent walkers before training. Meta-regression did not identify any effect of the covariates on the treatment effect. The majority of randomized controlled trials had small sample sizes, and the certainty of the evidence was very low.

CONCLUSION

Overground RE training may have a beneficial effect on walking ability and walking speed to complement conventional rehabilitation. Further large-scale and long-term, high-quality trials are recommended to enhance the quality of overground RE training and confirm its sustainability.
