Technique of Subcutaneous Infusion Anesthesia

Abstract

When using TLA, for many procedures it is better to infuse the anesthetic solution more slowly than usual, since this means that the patient feels neither pain or pressure. Slow infusion, because it takes longer, also leads to improved surface anesthesia. By using a volumetric infusion pump instead of a roll pump, it is for the first time possible to use this slow, painless, subcutaneous distribution of infusion solution, like a paravenous infusion, for local anesthesia in all operations without having to have a doctor guide the needle all the time (Fig. 10.1). This broadens the range of indications for local anesthesia, especially for children (Fig. 10.2) and for procedures in sensitive parts of the body (Fig. 10.10).
