Low Dose Ketamine Effectively Relieves pain for ED patients: Study Finds - Video

A new study that investigates low-dose ketamine (LDK) as an adjunct to morphine for treating acute pain has been published in the Academic Emergency Medicine (AEM), the peer-reviewed journal of the Society for Academic Emergency Medicine (SAEM).

The study highlights the potential of low-dose ketamine as a valuable tool in pain management, providing a safe and effective option for emergency medicine physicians managing acute pain.

Pain remains one of the most common and challenging complaints among patients presenting to the emergency department (ED). For individuals with opioid tolerance, achieving effective pain relief can be particularly difficult, as they often require higher doses of opioids, which increases risks of hyperalgesia and withdrawal symptoms. In their randomized, placebo-controlled trial, lead author Stine Fjendbo Galili, MD, and colleagues explored the effectiveness of low-dose ketamine as an adjunct to morphine in a diverse emergency department population with varying levels of opioid use. The study demonstrated that a single dose of 0.1 mg/kg of ketamine provided significant reductions in pain scores for 30 minutes compared to a placebo.

The study concluded that low-dose ketamine may be an effective short-term adjunct analgesic to morphine for managing acute pain, offering relief to both opioid-tolerant and opioid-naïve patients.
