Using a retrospective review of records, we will conduct a multivariate analysis to examine the relationship between exposure to ketamine, as an analgesic agent in combat related trauma care, the use of additional opioid pain medications, and patient reported pain levels.
This is a retrospective study to determine if there is a relationship between intravenous infusion of ketamine given for analgesia and the use of additional opioid pain medications and patient reported pain levels before and during ketamine usage. The investigator anticipates that records of up to 700 subjects will be reviewed for eligibility. The time period 24 hours before the initial ketamine therapy is initiated along with 24 & 48 hours after the start of ketamine therapy will be the time periods examined. The average/minimum/maximum pain scores during these time periods will be used. Medication usage will be calculated over the 24 hour time periods.
This protocol is presented as an initial step in exploring the possible relationship between the administration of ketamine as an analgesic agent, the potential reduction in pain medications, and the potential reduction of pain levels. With this the goals/objectives are as follows:
1. To compare morphine consumption in battlefield injured patients with acute pain 24 hours before the initiation of a ketamine infusion to the subsequent 48 hours following the start of infusion.
2. To compare average/minimum/maximum pain scores in battlefield injured patients with acute pain 24 hours before the initiation of a ketamine infusion to the subsequent 48 hours following the start of infusion.
3. To describe the pain trajectory in battlefield injured patients with acute pain after the initiation of ketamine infusions.
4. To measure the absolute and proportional incidence of ketamine associated side effects in battlefield injured patients with acute pain following the initiation of ketamine infusions.

Goal is to determine if in adults presenting to the Emergency Department (ED) with moderate to severe acute pain, Ketamine administered at 0.15 mg/kg will provide similar pain relief to Ke...
This study aims to determine the efficacy and safety of low dose ketamine in association with IV morphine in the management of acute moderate to severe pain in emergency department. We hy...
This study investigates the use of low doses of ketamine, along with opiate pain medication, is more effective at controlling the acute pain of patients in the emergency department than op...
This study will prospectively compare the mean Numerical Rating Scale (NRS) pain score reduction amongst three recommended dosing strategies of intravenous ketamine (0.1 mg/kg, 0.2 mg/kg, ...
The investigators previous research study comparing the efficacy of intravenous ketamine to morphine showed ketamine to provide equivalent relief of moderate to severe acute pain in emerge...
Ketamine has been shown to reduce chronic pain; however, the adverse events associated with ketamine makes it challenging for use outside of the perioperative setting. The ketamine metabolite (2R,6R)-...
Sub-dissociative dose ketamine (SDDK) is used to treat acute pain. We sought to determine if SDDK is effective in relieving acute exacerbations of chronic pain.
Pain management is complex regardless of whether the pain is acute or chronic in nature or non-cancer or cancer related. In addition, relatively few pain pharmacotherapy options with adequate efficacy...
This study was conducted to compare the effectiveness of low-dose ketamine versus ketorolac in pain control in patients with acute renal colic presenting to the emergency department (ED).
Redback spider envenoming causes severe pain lasting several days. A recent clinical trial found antivenom is not effective. We investigated ketamine for pain in redback spider envenoming. Ten adult p...
A cyclohexanone derivative used for induction of anesthesia. Its mechanism of action is not well understood, but ketamine can block NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE) and may interact with sigma receptors.
Acute pain that comes on rapidly despite the use of pain medication.
A hallucinogen formerly used as a veterinary anesthetic, and briefly as a general anesthetic for humans. Phencyclidine is similar to KETAMINE in structure and in many of its effects. Like ketamine, it can produce a dissociative state. It exerts its pharmacological action through inhibition of NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE). As a drug of abuse, it is known as PCP and Angel Dust.
A clinical syndrome with acute abdominal pain that is severe, localized, and rapid onset. Acute abdomen may be caused by a variety of disorders, injuries, or diseases.
Acute or chronic pain in the lumbar or sacral regions, which may be associated with musculo-ligamentous SPRAINS AND STRAINS; INTERVERTEBRAL DISK DISPLACEMENT; and other conditions.
Pain is defined by the International Association for the Study of Pain as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage”. Some illnesses can be excruci...
