Maybe intramuscular dose Ketamine as suggested on the internet, 3-5mg/kg on the patient who is already intoxicated from alcohol is not safe. Maybe less. I had fooled myself after the prior case Ketamine2 regarding my intoxicated beat up patient with bumps on his head. That patient didnt get hypoxic after given the IM ketamine. I learned. The patient didn't appreciate the effort or mistake thankfully.
Pain dose ketamine 0.3mg/kg in 100ml iv piggy bag dose would have been much safer. Just 20mg ivpb for a 70 kg patient.
I wonder after this case.
