Ketamine Infusion

If you require anesthesia, your healthcare provider may use ketamine hydrochloride (Ketalar®). Your dosage of this anesthetic will depend on several factors, such as your weight, how you respond to the drug, and whether other medications are used with ketamine.
 
Ketamine is typically administered as an injection into the vein (intravenously, or by IV) or as an injection into a muscle (intramuscularly, or IM). The infusion of ketamine is usually given continually and slowly, over 60 seconds. It may be used alone or in combination with other anesthetic medications. A trained healthcare provider will administer the ketamine infusion in a healthcare setting.
 
This drug has a high potential for abuse. If used illicitly or improperly, ketamine can cause dangerous and even life-threatening complications.
