“1 Introduction Lignocaine in high concentrations has the ability to block sodium channels and is used for local and regional anaesthesia and for antiarrhythmic treatment. Lignocaine is also thought to stabilize the cell membrane and have effects on inflammatory cells in lower concentrations [1, 2]. The definition of endometriosis is the presence of viable endometrial tissue outside the uterine cavity, most commonly located on the peritoneal surfaces in the lower abdominal cavity.
