Tip of the Day:

🔷🫀 Intravenous (Venous) Injection

🔄 Drug enters systemic circulation → right heart → lungs → left heart → high-flow organs.
🧠 CNS symptoms (tinnitus, dizziness, seizures) appear first.
❤️ At higher levels → cardiac toxicity (arrhythmias, arrest).
🌬️ Pulmonary “buffer” effect (lungs trap part of dose) gives some protection.
⚖️ Severity: Dose-dependent, influenced by protein binding & redistribution.
💉 Blocks with higher venous risk: Epidural, caudal, lumbar plexus, intercostal (due to rich venous plexuses).

🔴🩸 Intra-Arterial Injection

🚨 Central arteries (carotid/vertebral/coronary):

🔶Immediate direct high-concentration delivery to brain or heart.
⏱️ Onset: Seconds → seizures, LOC, arrhythmias.
💣 Small dose = catastrophic effect.
💉Blocks nearby: Interscalene, supraclavicular, stellate ganglion.

🦵 Peripheral arteries (e.g., femoral, tibial):

🔴Blood flows distally into limb, not brain/heart.
⚠️ Risk of limb ischemia, pain, necrosis at injection site.
📈 Systemic absorption is slower, so LAST is less abrupt, but still possible.
💉Blocks nearby: Femoral nerve block, adductor canal, popliteal sciatic.

✅ Take-Home Message: 💡💡

🎯Venous injection → systemic dilution → gradual CNS → cardiac toxicity.

🎯Central arterial injection → catastrophic CNS/cardiac LAST in seconds.

🎯Peripheral arterial injection → local ischemia + delayed systemic toxicity.

🎯Block risk depends on anatomical proximity to venous plexuses or arteries.
🔹Epidural/intercostal/lumbar plexus → venous.
🔹Interscalene/supraclavicular → central artery.
🔹Femoral/popliteal → peripheral artery.

💡 Remember: The vessel you hit decides the fight you face — 🫀 vein for systemic, 🧠/❤️ central artery for catastrophe, 🦵 peripheral artery for ischemia. Stay safe, inject slow, and always aspirate! 🔄💉

Gliding to a new high with Cereglide 92! A promising technology which will make aspiration EVT even more swift and efficient! #aspirationfirst #ADAPT #cereglide92 #stroke #outcome

A device described as the latest addition to a growing group of ‘super-large bore’ catheter technologies has demonstrated “extremely positive” outcomes in early clinical usage @MajidiShahram @brainconferenc1 @jjmt_neuro https://t.co/5TO83uLtAF
