About this study

In situations where intravenous access is not readily available or is unobtainable and the intranasal route is not feasible, another non-invasive route of ketamine administration, such as inhalation via breath-actuated Nebulizer (BAN), is becoming a viable alternative. The BAN allows the controlled, patient-initiated delivery of analgesics in a measured and titratable fashion. (18) Ketamine has been studied as a nebulized drug in a lot of different settings and for a lot of different reasons, such as to treat acute pain after surgery (like a sore throat after being intubated), as a pre-medication for general anesthesia, to treat cancer pain, and as a therapy for asthmaticus. Our research team has published two case series of 10 adult patients who were given nebulized ketamine (via BAN) for a variety of acute traumatic and non-traumatic painful conditions. The patients showed a 60% decrease in pain and a small number of side effects. Furthermore, our group published a randomized, double-blind trial of 120 adult patients evaluating the analgesic efficacy and safety of nebulized ketamine at three different dosing regimens for acute pain in the ED (0.75 mg/kg, 1 mg/kg, and 1.5 mg/kg), showing similar analgesic efficacy between the three different dosing regimens for short-term (up to 120 minutes) pain relief. Lastly, we recently completed a randomized, double-blind, double-dummy clinical trial comparing the analgesic efficacy and safety of nebulized ketamine and intravenous keta…
