The Effect of Intravenous Ketamine on Non Suicidal Self Injuries.

Non-suicidal self-injuries (NSSI) is a deliberate harm a person causes directly to their body, resulting in structural or functional damage, without suicidal ideation. This behavior is related to unbearable internal stress, thoughts, or mental pain, which NSSI assists in dismantling. To date, there is no generally approved therapy that assists in lowering NSSI. Ketamine is a sedative drug, presently at the focus of psychopharmacologic research, which was found to improve depression, when taken orally, and lower suicidal ideation, when given intravenously. Our aim is to assess the efficiency of intravenous ketamine in decreasing NSSI symptomology in women with a history of childhood sexual abuse presenting with such behavior. Participants will be recruited among hospitalized patients from the Tel-Aviv Medical Central psychiatric ward, who will present with either NSSI urges or behavior. The study design is a randomized control, double blind trial. Each patient will be assessed before, during, and after the trial by physical examination, blood tests and questionnaires. The patients will be randomized into research group (treated by ketamine and midazolam intravenously) or control group (treated intravenously via midazolam only). Our hypothesis is that treatment by intravenous ketamine will lower NSSI symptomology, and enable optimal treatment while being hospitalized.
