Methaemoglobinemia after Liposuction under Tumescent Local Anaesthesia - Diagnostic Value of Pulse Oximetry.

Background: Tumescent local anaesthesia with prilocain can lead to clinically significant methemoglobin levels. New generation multiple wavelength pulse oximeters (e. g.

Evaluation and application of a high performance liquid chromatographic method for prilocaine analysis in human plasma.

Background: Prilocaine, a local anesthetic of the amide type, is frequently applied in substantial doses during tumescent liposuction. Although it cannot be excluded that the subcutaneously infiltrated narcotic may enter the circulation and trigger adverse systemic reactions, prilocaine plasma levels have rarely been measured during routine tumescent surgery. We established and evaluated a high performance liquid chromatography (HPLC) method for analysis of this narcotic and used it to measure the drug in plasma samples drawn in the course of tumescent liposuction with prilocaine local anesthesia.
