Ver el código de «Nerve Block: Radial Nerve»

==Overview==
*Effective method of regional pain control of the forearm.

==Indications==
*Surgical anesthesia along the course of the radial nerve
*Postoperative anesthesia
*Radial Tunnel Syndrome
*Cheiralgia paresthetica or Wartenberg Syndrome

==Contraindications==
*Infection at the site
*Severe coagulopathy
*Allergy to local anesthetic 

==Equipment Needed==
*Alcohol/Betadine/Chlorhexidine
*Syringe, 1 mL, for local anesthetic
*Syringe, 5 mL, for nerve block
*Anesthetic - Lidocaine 1%/2%, bupivacaine 0.5%, or ropivacaine 0.5%
*Sterile Gloves
*Adhesive Bandage

==Procedure==
===Block at humerus level===
#Patient supine with arm abducted to 45 degrees and hand resting on abdomen
#Palpate deeply between the heads of the triceps muscle and brachialis muscle (musculospiral groove)
#Prepare skin with antiseptic solution
#Infiltrate injection site with 1mL of anesthetic 
#Insert a 25-gauge perpendicularly toward the musculospiral groove
#Identify the nerve by parathesia
#Aspirate to ensure you are not intravascular
#Slowly inject anesthetic

===Block at elbow level===
#Patient supine with arm abducted to 45 degrees
#Flex the elbow and identify the lateral margin of the biceps tendon at the elbow crease
#Prepare skin with antiseptic solution
#Infiltrate injection site with 1mL of anesthetic 
#Insert the needle just lateral to the tendon and advance slightly medial and cephalad towards the humerus
#Identify the nerve by parathesia
#Aspirate to ensure you are not intravascular
#Slowly inject anesthetic

===Block at wrist level===
#Prepare skin with antiseptic solution
#Infiltrate injection site with 1mL of anesthetic 
#Insert needle just above radial styloid and aim medially
#Aspirate to ensure you are not intravascular
#Slowly inject anesthetic and extend the infiltration laterally

===Ultrasound Guided===
*Please see [http://highlandultrasound.com/forearm-blocks/ Highland EM U/S Guide] for videos and tutorials

==Complications==
*Residual Paresthesia due to intraneuronal injection
*Systemic Toxicity due to intravascular injection 
*Local Site infection
*Hematoma
