Abstract
OBJECTIVES:Intravenous catheter placement is one of the most common sources of pain for children in inpatient settings. We sought to compare the efficacy of 2 cryotherapeutic treatments for this procedure: vapocoolant spray versus topical ice pack. METHODS: We prospectively enrolled 95 patients, aged 9 to 18 years, in a pediatric emergency department who required intravenous (IV) catheters as part of their treatment. Subjects were randomly assigned to receive vapocoolant spray or topical ice pack for 3 minutes, before IV catheter placement. Subjects completed visual analog scale (VAS) scores for 3 time points: baseline, pretreatment with ice or spray, and IV insertion. The principal investigator and 2 physicians viewing video recordings of the procedure also completed VAS scores for observed pain levels. Visual analog scale scores were compared using the Wilcoxon rank sum test. RESULTS: Although median VAS scores were similar, the change in VAS from baseline was of greater magnitude in the Painease group, indicating that it may be more effective. More subjects in the Painease group (76%) felt their treatment worked well, compared with 49% in the ice group. Physician-assigned VAS scores were lower and less variable than those of subjects. Most IV insertions were successful (83%). CONCLUSIONS: Vapocoolant spray may be more effective than ice as an analgesic for IV insertion. Subjects were more satisfied with vapocoolant spray. Neither agent caused a decrease in successful IV insertion rates.
