Equipment for Peripheral Nerve Blocks

Foundations of Regional Anesthesia

Ali Nima Shariat, Patrick M. Horan, Kimberly Gratenstein, Colleen McCally, and Ashton P. Frulla Introduction Over the past several decades, regional anesthesia equipment has undergone substantial technological advances. Historically, the development and consequent introduction of the portable nerve stimulator to…

Ultrasound-Guided Superficial Cervical Plexus Block

Upper Extremity

Figure 1: Needle and transducer position to block the superficial cervical plexus using a transverse view. Essentials  Indications: carotid endarterectomy, superficial neck surgery  Transducer position: transverse over the midpoint of the sternocleidomastoid muscle (posterior border)  Goal: local anesthetic spread around…

Ultrasound-Guided Interscalene Brachial Plexus Block

Upper Extremity

Figure 1: Ultrasound-guided interscalene brachial plexus block; transducer and needle position to obtain the desired ultrasound image for an in-plane approach. Essentials   Indications: shoulder and upper arm surgery   Transducer position: transverse on neck, 3-4 cm superior to clavicle, over external…

Ultrasound-Guided Supraclavicular Brachial Plexus Block

Upper Extremity

Figure 1: Supraclavicular brachial plexus; transducer position and needle insertion. Essentials   Indications: arm, elbow, forearm, and hand surgery   Transducer position: transverse on neck, just superior to the clavicle at midpoint   Goal: local anesthetic spread around brachial plexus, lateral and superficial…

Ultrasound-Guided Infraclavicular Brachial Plexus Block

Upper Extremity

Figure 1: In-plane needle insertion technique during infraclavicular brachial plexus block. Essentials   Indications: arm, elbow, forearm, and hand surgery   Transducer position: approximately parasagittal, just medial to coracoid process, inferior to clavicle   Goal: local anesthetic spread around axillary artery   Local anesthetic:…

Ultrasound-Guided Axillary Brachial Plexus Block

Upper Extremity

Figure 1: Transducer position and needle insertion in ultrasound-guided axillary brachial plexus block. Essentials   Indications: forearm and hand surgery   Transducer position: short axis to arm, just distal to pectoralis major insertion   Goal: local anesthetic spread around axillary artery   Local anesthetic:…

Digital Nerve Block

Upper Extermity

A digital block is the technique of blocking the nerves of the digits to achieve anesthesia of the finger(s). This technique is simple to perform and essentially devoid of systemic complications. It is a commonly used and effective method of…
