For hospitalized children, a vibrating cold device (VCD) may reduce the pain of an intravenous (IV) catheter insertion as well as topical lidocaine. Researchers including Katherine Finn Davis, PhD, RN, of the School of Nursing and Dental Hygiene, conducted a randomized controlled trial of 224 children. Topical lidocaine was applied at least 30 minutes before the insertion; for those randomized to receive the VCD, the device was activated 15 to 45 seconds prior to the needle puncture. Results showed no significant difference in pain scores using two standardized pain scales. The time needed to complete the procedure was significantly shorter for the VCD group (3 minutes vs 41 minutes). Further research using the VCD is needed, the researchers wrote. The study (PMID 28121978) is published in Pediatric Emergency Care.
