 The investigators propose a feasibility study of intranasal ketamine to provide analgesia and anxiolysis before minor procedures. This will be a single-blinded randomized study of inhaled ketamine in a convenience sample of children ages 4-12 years of age undergoing minor procedures. For the purpose of this study, the investigators will limit minor procedures to venipuncture and IV placement, and will further limit the patient population to children who are deemed by the investigators to show resistance to IV placement or venipuncture without premedication. The investigators have chosen the ages 4-12 years because these children are verbal and able to rate their pain on the VAS scales, because they are likely to require restraint and to require a staff member to assist parents with restraint, and because the Green study found this age range to have the fewest adverse events with ketamine.
