Summary
Patients who present with acute traumatic injuries in the pre-hospital setting or to the emergency department (ED) are treated with opioids, the current gold standard for severe acute pain therapy. Treatment with opioids has many disadvantages: the need of skilled manpower to administer the medication IV, numerous side effects- mainly cardiorespiratory depression- which necessitates post medication administration continuous monitoring of patients. IV administration may be difficult or impossible to provide in a number of extreme circumstances. For these reasons, there is a constant search for alternate treatment options for pain in acute traumatic injuries. IN ketamine has only recently been studied favorably in our department in adults, in an open, prospective study (Shimonovich at al 2016), and warrants further investigation in the setting of acute traumatic pain. Ketamine is a safe and efficacious analgesic and is overall well received both by patients and physicians. Side effects include: hallucinations and dissociation. As opposed to opioids, ketamine does not alter patients' respiratory and hemodynamic stability giving ketamine great therapeutic potential for pain reduction in trauma patients, pre-hospital patients, and battlefield injuries. The study we are conducting is designed to test and analyze the safety and efficacy of IN Ketamine compared to IV morphine in a setting of acute traumatic pain in the ED, when both medications are administered by the protocol as is customary for treatment of pain in the Emergency Medicine department, and will be a prospective, randomized, double blind, controlled study.
