Ketamine for Pain management
Ketamine may be used for postoperative pain management. Low doses of ketamine may reduce morphine use, nausea, and vomiting after surgery.
Ketamine has similar efficacy to opioids in a hospital emergency department setting for the management of acute pain and for control of procedural pain.
It may also be used as an intravenous analgesic with opiates to manage otherwise intractable pain, particularly if this pain is neuropathic. It has the added benefit of counteracting spinal sensitization or wind-up phenomena experienced with chronic pain. At these doses, the psychotropic side effects are less apparent and well managed with benzodiazepines. Ketamine is an analgesic that is most effective when used alongside a low-dose opioid; because, while it does have analgesic effects by itself, the doses required for adequate pain relief when it is used as the sole analgesic agent are considerably higher and far more likely to produce disorienting side effects. A review article in 2013 concluded, “despite limitations in the breadth and depth of data available, there is evidence that ketamine may be a viable option for treatment-refractory cancer pain”.

Ketamine Is Used as an anesthetic:
Anesthesia in children, as the sole anesthetic for minor procedures or as an induction agent followed by muscle relaxant and tracheal intubation
Asthmatics or people with chronic obstructive airway disease
As a sedative for physically painful procedures in emergency departments
Emergency surgery in field conditions in war zones
To supplement spinal or epidural anesthesia/analgesia using low doses
Since it suppresses breathing much less than most other available anesthetics, ketamine is used in medicine as an anesthetic; however, due to the hallucinations it may cause, it is not typically used as a primary anesthetic, although it is the anesthetic of choice when reliable ventilation equipment is not available.
Low-dose ketamine is sometimes used in the treatment of complex regional pain syndrome (CRPS). A 2013 systematic review found only low-quality evidence to support the use of ketamine for CRPS.
ketamine as a dissociative sedative in emergency medicine.
Ketamine is frequently used in severely injured people and appears to be safe in this group. A 2011 clinical practice guideline supports the use of ketamine as a dissociative sedative in emergency medicine. It is the drug of choice for people in traumatic shock who are at risk of hypo-tension. Low blood pressure is harmful in people with severe head injury[ and ketamine is least likely to cause low blood pressure, often even able to prevent it.
Ketamine is used as a bronchodilator in the treatment of severe asthma.
However, evidence of clinical benefit is limited.
To conclude,the effect of ketamine on the respiratory and circulatory systems is different from that of other anesthetics. When used at anesthetic doses, it will usually stimulate rather than depress the circulatory system.It is sometimes possible to perform ketamine anesthesia without protective measures to the airways. Ketamine is considered relatively safe because protective airway reflexes are preserved.
