The purpose of this study was to assess @entity1 's perception of @entity158 associated with peripheral intravenous (i.v.) cannulation, using 3 methods of applying local anesthetics. A prospective, randomized, quasi-experimental study was conducted, using a convenience sample of @entity1 and @entity1 , ASA physical status I, II, or III, undergoing outpatient or same-day surgery. Group 1 received a subcutaneous injection of 1% @entity3303 , group 2 received topical EMLA cream for 45 to 60 minutes, and group 3 received treatment with "Numby Stuff" for 40 mA minutes. After the intended analgesic treatment was complete, the @entity1 was asked to rate the @entity158 experienced during the skin-numbing process. An i.v. was then started using an 18-gauge i.v. catheter, and the @entity1 again was asked to rate the amount of @entity158 experienced with the catheter insertion. A visual analog scale was used as the tool of measurement for @entity158 . Results of the study showed that group 1 experienced a higher treatment @entity158 score than either group 2 or group 3, while group 2 experienced a higher @entity158 score when the i.v. was started than either group 1 or group 3. Of the 3 methods tested, results seem to indicate that the Numby Stuff system using iontophoresis is the superior method for decreasing the @entity158 associated with peripheral i.v. cannulation, and application of the analgesic method does not cause significant @entity158 .

1% XXXX injection, EMLA cream, or "numby stuff" for topical analgesia associated with peripheral intravenous cannulation.
