Summary
When treating severe trauma pain, paramedics now have evidence comparing two powerful options. In a major UK prehospital study, EMS providers administered either ketamine or morphine to 449 patients in ambulances. Both medications proved equally effective for pain control, with similar safety profiles. While ketamine didn't outperform morphine as hoped, it remains a viable alternative for paramedics treating acute trauma pain.

Summary
Scientists have developed new methods to track methoxphenidine (MXP), a concerning dissociative anaesthetic, in biological samples. Using advanced LC-MS/MS and chiral SFC-MS techniques, researchers measured MXP and its metabolite in rat serum and brain tissue. The findings reveal that MXP rapidly enters the brain, with one form (S-enantiomer) showing higher concentrations than its mirror image.
Abstract
Methoxphenidine (MXP), a dissociative anaesthetic derivative, has garnered the attention of toxicologists for their increasing abuse and associated...
