Ultrasound Guided Regional Anesthesia
Ultrasound guided regional anesthesia describes a technique in which an Ultrasound machine is used to directly visualize the target nerves in order to be able to inject local anesthetic (numbing medication) directly around the nerve. Injecting local anesthetic around certain nerves that supply a surgical site with pain sensation allows the patient to experience less pain in the post-operative period, and also allows the patient to require less pain medication during and after their scheduled surgery. This in turn allows the patient to experience less side effects and have a quicker, smoother recovery. Ultrasound has been shown to improve the quality of the nerve block, shorten the onset time and improve the success rate when compared to other nerve block techniques. The use of ultrasound to guide nerve blocks has also been shown to reduce the number of needle attempts needed for nerve localization which may prove to reduce the risk of nerve injury. Overall, ultrasound guided nerve blocks improve pain control and improve patient satisfaction. For more information on nerve blockade please click here.
