⚡ 𝐏𝐀𝐑𝐓 𝐀: 𝐅𝐫𝐨𝐦 𝐏𝐍𝐒 𝐌𝐚𝐜𝐡𝐢𝐧𝐞 𝐭𝐨 𝐏𝐚𝐭𝐢𝐞𝐧𝐭 𝐓𝐢𝐬𝐬𝐮𝐞 : 𝐄𝐥𝐞𝐜𝐭𝐫𝐨𝐧𝐢𝐜 𝐂𝐮𝐫𝐫𝐞𝐧𝐭 → 𝐈𝐨𝐧𝐢𝐜 𝐂𝐮𝐫𝐫𝐞𝐧𝐭 #RegionalAnesthesia #PeripheralNerveStimulator #PNSPrinciples #NerveStimulation #ElectronicCurrent #IonicCurrent #ElectricField #NeedleTipCurrent #NerveBlock #TipOfTheDay #MyRATips 𝐓𝐢𝐩 𝐨𝐟 𝐭𝐡𝐞 𝐃𝐚𝐲 : 🔷 𝟏. 𝐏𝐍𝐒 𝐦𝐚𝐜𝐡𝐢𝐧𝐞 𝐝𝐨𝐞𝐬 𝐧𝐨𝐭 𝐜𝐫𝐞𝐚𝐭𝐞 𝐜𝐡𝐚𝐫𝐠𝐞 ▪️ It creates an electrical pulse ▪️ It generates a potential difference between two electrodes ▪️ This potential difference drives current through the circuit 🔷 𝟐. 𝐈𝐧𝐬𝐢𝐝𝐞 𝐦𝐚𝐜𝐡𝐢𝐧𝐞 𝐚𝐧𝐝 𝐜𝐚𝐛𝐥𝐞𝐬 ▪️ Current is carried by electrons ▪️ Electrons move through metal conductors ▪️ This is called electronic current 🔷 𝟑. 𝐀𝐭 𝐭𝐡𝐞 𝐧𝐞𝐞𝐝𝐥𝐞-𝐭𝐢𝐬𝐬𝐮𝐞 𝐢𝐧𝐭𝐞𝐫𝐟𝐚𝐜𝐞 ▪️ Current does not enter tissue as electrons ▪️ Metal conduction changes into tissue conduction ▪️ Tissue conducts current mainly through ions 🔷 𝟒. 𝐈𝐧𝐬𝐢𝐝𝐞 𝐩𝐚𝐭𝐢𝐞𝐧𝐭 𝐭𝐢𝐬𝐬𝐮𝐞 ▪️ Charge carriers are mainly: 🔸 Na⁺ 🔸 K⁺ 🔸 Cl⁻ 🔸 Ca²⁺ ▪️ This is still electric current ▪️ But the carrier is ionic, not electronic 🔷 𝟓. 𝐄𝐥𝐞𝐜𝐭𝐫𝐢𝐜 𝐟𝐢𝐞𝐥𝐝 𝐟𝐨𝐫𝐦𝐚𝐭𝐢𝐨𝐧 ▪️ The cathode and anode create an electric field in tissue ▪️ This field is strongest near the small needle tip ▪️ The field influences nearby nerve membrane voltage ✅ 𝐊𝐞𝐲 𝐓𝐚𝐤𝐞𝐚𝐰𝐚𝐲 🔸 In cables: electronic current 🔸 In tissue: ionic electric current 🔸 PNS works by transferring an electrical pulse from machine to biological tissue ⚡PNS current is 𝐄𝐋𝐄𝐂𝐓𝐑𝐎𝐍𝐈𝐂 in the machine, 𝐈𝐎𝐍𝐈𝐂 in the patient, & 𝐏𝐇𝐘𝐒𝐈𝐎𝐋𝐎𝐆𝐈𝐂 in Nerves.
