Summary

This trial is studying whether a longer or shorter infusion of ketamine reduces side effects in people with severe pain in the emergency department.

Who is the study for?
This trial is for adults over 18 in the Emergency Department with acute, severe pain from conditions like abdominal or musculoskeletal pain. They must be alert, oriented, and able to consent. Excluded are pregnant or breastfeeding individuals, those with altered mental status or unstable vitals, recent drug/alcohol use, certain psychiatric conditions, recent analgesic use, chronic opiate users, and those with specific heart diseases.
What is being tested?
The study tests if a low dose of Ketamine given slowly through an IV over 30 minutes reduces side effects compared to a faster infusion over 15 minutes while still controlling severe pain effectively in emergency situations.
What are the potential side effects?
Ketamine may cause side effects such as feelings of dissociation (feeling detached from reality), changes in blood pressure and heart rate, nausea or vomiting. The trial aims to see if slower infusion rates can reduce these potential side effects.
