4 Clinical Trials for Various Conditions
The purpose of this study is to evaluate if the Synera Patch (lidocaine/tetracaine patch), used to numb the skin before IV placement, is effective in reducing pain associated with propofol IV administration when inducing general anesthesia, compared to Gebauer's Ethyl Chloride topical anesthetic skin refrigerant.
The main objective is to evaluate if combining placing the Synera patch and using Propofol /Lidocaine mixture will further decrease the pain associated with the IV injection of Propofol.
Intravenous lidocaine is commonly given through an intravenous (IV) line prior to injection of propofol to reduce the amount of pain during propofol injection. The investigators want to study if giving the lidocaine through the IV while the forearm on the same limb has a tourniquet applied to it to prevent "washing out" of the lidocaine prior to propofol injection helps reduce propofol injection pain.
The primary hypothesis is that esmolol and lidocaine, when given without the use of a tourniquet, provide relief of propofol injection pain that is superior to placebo when assessed using the propofol pain scoring tool
