🩺 Digital Nerve Block Procedure 🩺 ### Steps: 1. Initial Insertion: - Location: 💉 Insert the needle on the dorsal surface of the proximal phalanx. - Direction: 🏹 Advance toward the volar surface, staying tangential to the phalanx. - Aspirate: 🩸 Ensure no inadvertent vascular puncture. - Injection: 💧 Deposit 1 mL of anesthetic solution. While withdrawing the needle, inject an additional 1 mL back to the skin surface. 2. Second Injection: - Reinsert: 🔄 Needle in the same location, directing it across the dorsum of the digit. - Band Injection: 🖐️ Inject a 1-mL band of anesthetic solution into the subcutaneous space across the dorsum. - Repeat: 🔁 Initial injection process on the other side of the digit. 3. Alternative Approach: - Metacarpal Block: 🖋️ Block the digital nerves at their bifurcation adjacent to the metacarpal heads. - Usage: 👍 Particularly useful for long and ring finger anesthesia. #NEETPG #INICET #MarrowApp #PrepLadder #DocTutorials #MedStudentLife #CerebellumStudy

🩹 Assessing Digital Nerves for Injuries 🩹 ### Procedure: 1. Two-Point Discrimination: 🖐️ Measure on the volar pad before anesthetic injection. - Normal Range: 📏 Less than 6 mm at the fingertips, often less than 2 mm. 2. Comparison: 🔍 Compare the injured digit with the contralateral normal digit. ### Importance: - 🚑 Helps evaluate nerve function and potential injury severity. - 🧠 Ensures accurate diagnosis and appropriate treatment. #DigitalInjuries #NerveAssessment #MedicalExamination #PatientCare #NEETPG #INICET #MarrowApp #PrepLadder #DocTutorials #MedStudentLife #CerebellumStudy

💉 Techniques to Reduce Needle Puncture Pain 💉 ### Methods: 1. Topical Anesthetic: 🧴 Apply before injection. 2. Warming Agent: 🌡️ Warm the local anesthetic agent. 3. Skin Stretching: 🤲 Stretch the skin at the puncture site. 4. Skin Vibration: 💨 Vibrate the skin adjacent to the area. 5. Patient Distraction: 🗣️ Talk to the patient during the process. 6. Small-Bore Needle: 🪡 Use a 27 to 30 gauge needle. 7. Injection Technique: - 💉 Small pulse or slow injection. - 🔍 Insert through enlarged pores or hair follicles. - ↕️ Insert needle perpendicular to skin surface. - 🔼 Insert needle bevel-up. 8. Aerosol Refrigerant: ❄️ Numb the skin before injection. ### Benefits: - 🌟 Reduces pain and anxiety during injections. - 👍 Enhances patient comfort and cooperation. #PainManagement #MedicalTips #NeedleInjection #Anesthesia #PatientCare #NEETPG #INICET #MarrowApp #PrepLadder #DocTutorials #MedStudentLife #CerebellumStudy --- 🔔 Goal Alert!

💊 Enhancing Local Anesthesia: Epinephrine, Clonidine, and Sodium Bicarbonate 💊 ### Epinephrine: - Benefits: Increases anesthesia duration, controls bleeding, slows systemic absorption. - Safety: Safe in end-arterial fields (e.g., fingers, toes) for healthy patients. Avoid in cases of digital vascular injury, Raynaud’s disease, or Berger’s disease. ### Clonidine: - Usage: Alternative to epinephrine, prolongs anesthesia. - Dosage: 0.5 microgram/kg (max 150 micrograms). Exceeding this can cause sedation, hypotension, and bradycardia. ### Sodium Bicarbonate: - Purpose: Reduces injection pain, shortens onset of action by raising tissue pH. - Buffering: - Lidocaine: Add 1 mL of sodium bicarbonate 8.4% to 9 mL of 1% lidocaine. - Bupivacaine: Add 1 mL of sodium bicarbonate 8.4% to 29 mL of 0.25% bupivacaine. - Note: Buffering may cause anesthetic precipitation and degrade epinephrine but remains effective for at least 1 week. #MedicalEducation #Anesthesia #PainManagement #Pharmacology #LocalAnesthetics #NEETPG #INICET #MarrowApp #PrepLadder #DocTutorials #MedStudentLife #CerebellumStudy --- 🔔 Goal Alert!

💉 PHARMACOLOGY: Local Anesthetics 💉 Local anesthetics are classified into two groups: esters and amides. They function by reversibly blocking sodium channels, which inhibits the propagation of nerve impulses. This blockade impacts smaller nerve fibers first, reducing pain and temperature sensation, followed by the loss of touch, deep pressure sensation, and eventually motor function. ### Key Differences: - Esters: Hydrolyzed by cholinesterase enzymes in plasma. - Amides: Metabolized by hepatic microsomal enzymes. ### Selection Criteria: - Onset of Action - Duration of Anesthesia - Potential for Systemic Toxicity #MedicalEducation #Pharmacology #LocalAnesthetics #PainManagement #NEETPG #INICET #MarrowApp #PrepLadder #DocTutorials #MedStudentLife #CerebellumStudy --- Stay informed and up-to-date by engaging with these posts!
