The use of intravenous infusion therapy with lidocaine or ketamine has been of interest in several chronic pain conditions. Studies showed a benefit in immediate pain reduction and even longer lasting pain relief for treatment approaches with lidocaine and ketamine.~While there is a broad database on the use of lidocaine and ketamine in chronic pain management as separate agents, very few pre-clinical animal studies have investigated the combined use of said analgesics and none of them reports their combined use in chronic pain patients.~This study is to retrospective investigate the effects of the simultaneous i.v. administration of lidocaine and ketamine on a four to six weeks interval in treatment refractory different chronic pain conditions.
