|a The NMDA receptor mediates glutamate excitatory neurotransmission in the brain, and it is hypothesized that a dysfunction in this regulation may play a role in the etiology of depressive symptoms. Ketamine is proposed to help balance the dysfunction, however, by blocking the NMDA receptor; side effects such as vivid dreams and a dissociative effect (where the patient experiences a separation of body and mind) occur frequently. While these side effects are undesirable for the therapeutics, it has created an illicit market for ketamine in certain populations where it is better known as "Special K". Ketamine can be given through several routes including intravenous push or infusions, intramuscular, intranasal, and orally. Investigations have mainly utilized IV infusions due to the precise dosing and ability to adjust if known side effects occur.

|a Patients who receive ketamine require close monitoring of blood pressure, heart rate, respiratory rate, transcutaneous O2 saturation as well as for emergence reactions (recovery reaction including agitation, hallucinations, dreams and depersonalization) when ketamine wears off. For this reason, current practice is for patients to receive the infusions in clinics with monitoring capabilities, which may be a significant shift in practice from current oral pharmacotherapy where patients can be monitored as outpatients. Given the lack of direction from major psychiatric associations, the utility of ketamine for certain mental health disorders is uncertain. The purpose of this report is to review the clinical effectiveness of intravenous ketamine for the treatment of depression, PTSD, and suicidal ideation, as well as the evidence-based guidelines for its use in these conditions

|a Ketamine emerged as a novel treatment for certain mental health disorders in 2000 when Berman et al. published a seven patient RCT of intravenous (IV) ketamine compared to a saline placebo showing a reduction in the Hamilton Depression Rating Scale (Ham-D). This was the first suggestion that ketamine could be a benefit for treating mental health disorder and since previous investigations on treatment of mental health disorders have focused on the monoamines (dopamine, norepinephrine and serotonin) this approach may have great potential. Current psychiatric guidelines for treatment of major depressive disorder (MDD), post-traumatic stress disorder (PTSD), and suicidal ideation do not include statements regarding the use of ketamine however research continues to be published. Ketamine is a rapid acting, non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist that is used as a general anesthetic with analgesic properties used in human and veterinary medicine.
