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.

(Click the link to comment and to vote - voting not working through email, sorry!) A 12 year old boy with a history of ADHD on Adderall comes in for acute onset weakness of his bilateral upper arms, particularly on the right side. He had a viral URI 1 week ago with fever, cough, congestion, sore throat, from which he had recovered. For the past week, he did not take the Adderall because he had been sick and “forgot” to resume. On physical exam, his right arm is flaccid and motionless at his side, and he is unable to use it at all. He is able to lift his left arm partly against gravity, but it is weak. He has a low-grade fever of 38, and mild neck stiffness. His mental status is normal. [yop_poll id="71"]
