Nebulized Ketamine Used for Pain Management of Orthopedic Trauma.

Abstract

BACKGROUND:

Ketamine is a noncompetitive N-methyl-D-aspartate/glutamate receptor complex antagonist that decreases pain by diminishing central sensitization and hyperalgesia. When administered via i.v. (push-dose, short infusion, or continuous infusion) or intranasal routes, ketamine has shown to be effective in patients with acute traumatic pain. However, when i.v. access is not attainable or readily available, the inhalation route of ketamine administration via breath-actuated nebulizer (BAN) provides a noninvasive and titratable method of analgesic delivery. The use of nebulized ketamine has been studied in areas of postoperative management of sore throat and acute traumatic musculoskeletal and abdominal pain. To our knowledge, this is the first case series describing the use of nebulized ketamine for analgesia and orthopedic reduction.

CASE SERIES:

We describe 4 patients who presented to the emergency department with acute traumatic painful conditions (one patellar dislocation, one shoulder dislocation, and two forearm fractures) and received nebulized ketamine for management of their pain. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Administration of nebulized ketamine via BAN can be used as analgesic control for musculoskeletal trauma, as it can be administrated to patients with difficult i.v. access, has a rapid onset of analgesic effects with minimal side effects, and remains opioid-sparing.
