A systematic review and meta-analysis of new interventions for peripheral intravenous cannulation of children.

OBJECTIVE: Establishing intravenous access in children is often challenging for health professionals. Multiple attempts at peripheral intravenous cannulation (PIVC) cause increased pain and delayed delivery of therapy. Our objective was to synthesize and evaluate the best evidence for novel interventions designed to improve pediatric PIVC. METHODS: We searched for published and unpublished studies using MEDLINE, Cochrane Central Register of Controlled Trials, EMBASE, CINAHL, Web of Science, ClinicalTrials.gov, and Google.ca. We included studies for meta-analysis if they were randomized, evaluated an intervention other than ultrasound, and reported on 1 of 3 primary outcome measures: success or failure of PIVC, number of attempts to successful cannulation, and procedure time. Two blinded reviewers assessed studies for eligibility and applied a data extraction form to those included. Study quality was assessed using the Cochrane Risk of Bias Tool. RESULTS: Seven studies met the inclusion criteria. Randomized controlled trials (RCTs) of 3 different interventions were identified. A meta-analysis of 3 RCTs found that use of a transilluminator was associated with a decreased risk of first-attempt PIVC failure (risk ratio, 0.66; confidence interval, 0.41-1.06). Meta-analysis of 3 other RCTs found that near-infrared light devices do not impact the risk of first-attempt PIVC failure (risk ratio, 0.99; confidence interval, 0.74-1.33). CONCLUSIONS: Near-infrared light devices might be efficacious in selected subpopulations, but the available evidence does not support an overall benefit in the pediatric population. Transilluminators modestly improve pediatric PIVC, but the clinical significance of this benefit is questionable. Nitroglycerin ointments may increase the risk of PIVC failure and are associated with adverse effects.

Ultrasonographically guided peripheral intravenous cannulation of children and adults: a systematic review and meta-analysis.

STUDY OBJECTIVE: Peripheral intravenous cannulation is procedurally challenging and painful. We perform a systematic review to evaluate ultrasonographic guidance as an aid to peripheral intravenous cannulation. METHODS: We searched MEDLINE, Cochrane Central Register of Controlled Trials, EMBASE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, ClinicalTrials.gov, and Google.ca. We included randomized trials evaluating ultrasonographically guided peripheral intravenous cannulation and reporting risk of peripheral intravenous cannulation failure, number of attempts, procedure time, or time from randomization to peripheral intravenous cannulation. We separately analyzed pediatric and adult data and emergency department (ED), ICU, and operating room data. Quality assessment used the Cochrane Risk of Bias Tool. RESULTS: We identified 4,664 citations, assessed 403 full texts for eligibility, and included 9 trials. Five had low risk, 1 high risk, and 3 unclear risk of bias. A pediatric ED trial found that ultrasonography decreased mean difference (MD) in the number of attempts (MD -2.00; 95% confidence interval [CI] -2.73 to -1.27) and procedure time (MD -8.10 minutes; 95% CI -12.48 to -3.72 minutes). In an operating room pediatric trial, ultrasonography decreased risk of first-attempt failure (risk ratio 0.23; 95% CI 0.08 to 0.69), number of attempts (MD -1.50; 95% CI -2.52 to -0.48), and procedure time (MD -5.95; 95% CI -10.21 to -1.69). Meta-analysis of adult ED trials suggests that ultrasonography decreases the number of attempts (MD -0.43; 95% CI -0.81 to -0.05). Ultrasonography decreased risk of failure (risk ratio 0.47; 95% CI 0.26 to 0.87) in an adult ICU trial. CONCLUSION: Ultrasonography may decrease peripheral intravenous cannulation attempts and procedure time in children in ED and operating room settings. Few outcomes reached statistical significance. Larger well-controlled trials are needed.
