Brief Summary

Propofol is a drug commonly used for induction of general anesthesia in children as well as adults; however, propofol can cause pain on injection, possibly more frequently in children. One common method of preventing propofol injection pain is the injection of lidocaine just prior to the injection of propofol through an intravenous catheter. This practice is sometimes, but not universally, effective, and involves exposure of patients to an additional drug. Our proposal is to use a non-pharmacologic adjunct in an attempt to attenuate the pain of propofol injection. The Buzzy® personal pain relief device is an FDA-approved product that provides non-pharmacologic relief of pain from minor painful procedures in children. The investigators propose the non-invasive Buzzy® personal pain relief device might prove just as effective at relieving the pain of propofol injection as the injection of intravenous lidocaine just prior to propofol injection. Randomized groups and a blinded observer will be used in this study of 106 children, with one group of patients receiving a current standard of care for reduction of the pain of propofol injection, that is, lidocaine prior to propofol, and one group receiving the placement of the Buzzy® device above the injection site prior to injection of propofol to reduce the pain of propofol injection.

Outcome Measures

Primary Outcomes (1)

• Non-inferiority of Buzzy pain relief device as compared to intravenous lidocaine at preventing pain on injection of propofol

  Two scales will be used by the observer to rate the amount of pain, if any, on propofol injection, the FLACC (face, legs, activity, cry, consolability) Scale and the Cameron Four Point Scale for Pain on Propofol Injection. The FLACC Scale is a 0-10 scale where the observer rates pain based on facial expression, movement of the body and legs, vocalization, and reassurability. The Cameron Scale was developed by researchers to specifically rate the pain of propofol injection for a previous study, and uses the presence or absence of grimace, cry, and withdrawal to rate pain on a 0-3 scale. Both scales are being used because the FLACC Scale was not specifically designed for propofol pain, and has some limitations in its application for this purpose; however, the Cameron Scale is limited by its narrow application of three types of expressions of pain.

  Every minute starting 1 minute prior to induction of anesthesia, during induction, and after induction of anesthesia for a total of ten minutes
