You are seeing an 18-month-old brought in by ambulance for simple febrile seizure that lasted 2 minutes. You have determined the source of his fever to be viral URI with acute otitis media. He has fully recovered, his temperature has normalized (from 40C) with antipyretic, and he is interactive and playful now. His neurologic exam is normal, and he has no significant past medical history. His parents are asking about whether this will happen again, whether he is at higher risk of epilepsy, and whether he will have any negative neurologic outcome.

You are seeing an 8 year old boy brought in by ambulance for a first time unprovoked afebrile seizure. The seizure was generalized tonic-clonic and lasted 3 minutes then self-resolved. The child is now back to baseline. A thorough history and physical exam has revealed no clear etiology for the seizure, and the neurologic exam is normal. The child was well prior to the seizure and has no significant past medical history. Blood glucose in the field was 98. The child is well-appearing and can easily obtain follow-up with his primary physician in a timely fashion.

Tips and Tricks

Success rates in infant lumbar punctures may be declining as we do fewer and fewer (doing fewer is a good thing, except that we get less experience). One thing that can improve success is early stylet removal. The stylet is kept in when entering the skin in order to avoid the very rare complication of intraspinal epidermoid tumors. However, once the needle is past the epidermis and dermis, such that a plug of skin tissue cannot be cored out by the hollow needle and deposited into the spinal canal, the stylet can be removed. Here are two excellent FOAMed discussions of this practice and the advantages: http://pemcincinnati.com/blog/wwdwwd-early-stylet-removal-lp/ and https://pedemmorsels.com/spinal-needle-stylet/
Mucosal atomizer devices improve administration of intranasal medications. Intranasal fentanyl 1.5 mcg/kg is a great way to give stronger pain medication (eg for fractures) without placing an IV. Intranasal midazolam 0.2 mg/kg (use concentrated 5mg/mL form to keep total volume < 1mL per nostril) can be used to treat active seizures when no IV access is yet obtained, or as an anxiolytic for procedures. Intranasal naloxone at a standard dose of 4 mg is being provided to opiate addicts to use in case of overdose. A commercial device is available, but currently some lots are being recalled (check here for recalled lots), or you may simply not have one in stock. Here's how to make an improvised atomizer courtesy of Faisal Alghamdi of KFMC Riyadh. Hook up a 3 way stopcock with the lever turned so that all 3 ports are open to 1) a 14 or 16 gauge angiocath, 2) a syringe with the medication you wish to deliver, and 3) oxygen tubing. Hook the other end of the oxygen tubing up to oxygen and turn up to 5-10 L/min. Place the angiocath in the nostril and gently & slowly depress the plunger of the medication. See picture and video below. img_1123 Click here to see a video and compare to commercial device here
