Brief Summary:

In the situation when intravenous access is not readily available or unobtainable, or when prehospital delays to obtain intravenous access are not warranted, sub-dissociative dose ketamine can be administered via intranasal (IN) route. The data supporting IN is not set on the optimum intranasal dose (range 0.75-1 mg/kg) and frequencies of administration. In addition, IN administration of SDK for adult patients in the ED requires a highly concentrated solution that is not routinely stock in the ED. Hence, another non-invasive route exists such as nebulization via a Breath-Actuated Nebulizer which allows a controlled patient-initiated delivery of analgesics in titratable fashion.

Nebulized administration of ketamine however, has only been studied in the areas of acute postoperative pain management, cancer palliation, and status asthmaticus therapy (ref). To our knowledge, there are no prospective randomized trials that evaluated a role of nebulized SDK role in managing acute pain due to extremity trauma in the prehospital arena.

We aim to evaluate analgesic efficacy and safety of sub-dissociative dose ketamine administered prehospital via breath-actuated nebulizer at 1.0 mg/kg for patients with acute traumatic extremity injuries.

sub-dissociative dose ketamine administered prehospitally via breath-actuated nebulizer at 1.0 mg/kg for patients with acute pain
Drug: Nebutlized Ketamine
The PK-BAN package will be opened and weight -based dose of ketamine will be administered to the patient via BAN. The medication will be delivered with a minimum time of 5 min and maximum time of 15 min.
Other Name: ketamine

Primary Outcome Measures :
  1. Change in Pain Scores [ Time Frame: 30 minutes ]
    The primary outcome will include a percentage of patients achieving a 20% or greater change in pain scores on numeric rating pain scale (NRS) ranging form 0 no pain to 20 severe pain for the baseline to 30 minutes post-analgesic administration.

Secondary Outcome Measures :
  1. Rescue Analgesia [ Time Frame: 30 minutes ]
    The secondary outcomes will include a need for second or third dose, a need for rescue analgesia at either 15 and 30 minutes
