BackgroundUltrasound-assisted lumbar puncture in the pediatric emergency medicine setting has not been well established, but ultrasound could serve as a valuable tool in this setting.ObjectiveTo assess whether ultrasound increases provider confidence in identifying an insertion point for lumbar puncture.MethodsA feasibility study was conducted using a convenience sample of pediatric emergency patients requiring lumbar puncture. Provider confidence in selecting a needle insertion site for lumbar puncture using ultrasound assistance was compared to provider confidence using traditional landmarks alone. A simple technique using a linear probe is described.ResultsNineteen patients were included in the study, with the primary end point the mean confidence score (based on a five-point Likert scale) in identifying a needle insertion site prior to and after using ultrasound. Using the Wilcoxon signed-rank test, the mean confidence score was 2.89 with the landmark procedure alone, and 4.79 with ultrasound assistance, yielding an average score difference of 1.90 (95% confidence interval 1.23-2.56; Wilcoxon p < 0.001, paired t-test p < 0.001). Thus, compared to the landmark procedure, the use of ultrasound was associated with a significantly higher average confidence score.ConclusionThe use of ultrasound in the pediatric emergency setting can be a valuable adjunct with lumbar puncture.Copyright © 2014 Elsevier Inc.
