BackgroundFor peripherally inserted central catheter (PICC) inserting, tranquil cooperation of children for an extended period is often required. Therefore, sedation is routinely induced clinically prior to PICC inserting. Chloral hydrate is a commonly used sedative for children. However, its clinical acceptance has remained low. And the sedation effect is non-satisfactory. Previous studies have confirmed the safety and effectiveness of intravenous/oral dosing or nasal dripping for sedation during the examinations of electrocardiography and computed tomography. Yet few studies have assessed the sedating efficacy of dexmedetomidine nasal drops for PICC inserting.MethodsFrom a cohort of 40 hospitalized patients scheduled for PICC inserting, 15 children employing a novel sedative mode of dexmedetomidine nasal drops at a dose of 2 ug/kg were assigned into group A while group B included another 25 children sedated routinely via an enema of 10% chloral hydrate at a dose of 0.5 mL/kg. The Ramsay's scoring criteria were utilized for assessing the status of sedation. Two groups were observed with regards to success rate of sedation, onset time of sedation and occurrences of adverse reactions.ResultsStatistical inter-group differences existed in success rate and onset time of sedation. The success rate of group A was higher than that of group B (93.3% vs 64.0%, X2 = 4.302, P = .038 < 0.05). Group A had a faster onset of sedation than group B (14.86 ± 2.57 vs 19.06 ± 3.40 minutes, t = 3.781, P = .001 < 0.05). No inter-group difference of statistical significance existed in occurrence of adverse reactions (P = 1.000 > 0.05). Logistic regression analysis showed that the success rate of sedation in group A was higher than that in group B, and the difference was statistically significant (P = .036 < 0.05).ConclusionsFor sedating burn children, nasal dripping of dexmedetomidine is both safe and effective during PICC inserting. Without any obvious adverse reaction, it may relieve sufferings and enhance acceptance.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
