The adductor canal block (ACB) is a regional anesthesia technique that numbs the saphenous nerve in the thigh, used chiefly for pain relief after knee replacement surgery.
Axillary brachial plexus block
The axillary brachial plexus block, or axillary block, is a regional anesthesia technique that numbs the forearm, wrist, and hand for surgery via injection in the armpit.
Brachial plexus block
A brachial plexus block, also called brachial plexus blockade, is a regional anesthesia technique that numbs the shoulder, arm, or hand for surgery and pain control.
Cervical plexus block
Cervical plexus block is a regional anesthesia technique that injects local anesthetic near the C2–C4 nerve roots to numb the neck, used mainly for carotid endarterectomy in awake patients.
Continuous erector spinae plane block
The continuous erector spinae plane block is a regional anesthesia technique using a catheter to infuse local anesthetic along the spine for chest and abdominal pain relief.
Erector spinae plane block
The erector spinae plane block, or thoracic erector spinae plane block, is a regional anesthesia technique that anesthetizes thoracic spinal nerves for perioperative and chronic pain relief.
ESP trial
ESP trial: randomized clinical trials of the erector spinae plane block (ESPB) for pain after laparoscopic sleeve gastrectomy in obesity; mixed results, not recommended by 2025 PROSPECT guidelines.
Fascia iliaca compartment block
The fascia iliaca compartment block, or fascia iliaca block, is a regional anesthesia technique used mainly for pain control in hip fracture and hip and knee surgery.
Fascial plane block
A fascial plane block is a regional anesthesia technique injecting local anesthetic between fascial layers to numb multiple nerves, used in abdominal, chest, and breast surgery.
Intercostal nerve block
An intercostal nerve block is a regional anesthesia technique that numbs the chest wall, used after chest, breast, or abdominal surgery and for rib fractures.
Intercostal plane block
The intercostal plane block is a regional anesthesia technique targeting the intercostal sulcus to numb nerves. It provides dermatomal numbness for thoracic and upper abdominal pain after surgery.
Interfascial plane block
An interfascial plane block is a regional anesthesia technique that injects local anesthetic between fascial layers to numb nerves, used in abdominal, breast, and thoracic surgery.
Interpleural Analgesia
Interpleural (intrapleural) analgesia: regional anesthesia injecting local anesthetic into the pleural cavity for retrograde spread to intercostal nerves; developed by Kvalheim and Reiestad 1984–1986; used after cholecystectomy, renal and breast surgery; limited by pneumothorax and toxicity.
Interscalene nerve block
The interscalene nerve block is a regional anesthesia technique that injects local anesthetic between the scalene muscles of the neck to numb the shoulder and upper arm for surgery.
iPACK block
The iPACK block, short for infiltration between the popliteal artery and capsule of the knee, is an ultrasound-guided technique relieving posterior knee pain after knee replacement while sparing motor function.
Paracervical block
A paracervical block is a regional anesthesia technique in which local anesthetic injected beside the cervix numbs the cervix and lower uterus, used for IUD insertion, hysteroscopy, and brachytherapy.
Paravertebral block
A thoracic paravertebral block is a regional anesthesia technique injecting local anesthetic beside the spine to block chest nerves, used after breast and thoracic surgery.
PECS block
The PECS (pectoral nerve) block is an ultrasound-guided fascial plane block that numbs the anterior chest wall, used mainly for breast surgery and pacemaker insertion.
Pectoral nerve block II
The pectoral nerve block II (PECS II) is an ultrasound-guided nerve block of the chest wall, introduced in 2012 and used mainly as an opioid-sparing adjunct for breast surgery.
Peribulbar block
A peribulbar block is a regional anesthesia technique for eye surgery, injecting local anesthetic outside the muscle cone of the orbit; it is the most common regional technique for cataract surgery.
Pericapsular nerve group block
The pericapsular nerve group (PENG) block is an ultrasound-guided regional anesthesia technique introduced in 2018 that injects anesthetic between the psoas tendon and ilium to relieve hip fracture pain while largely sparing motor function.
Posterior superior intercostal plane block
The posterior superior intercostal plane block, or SPSIP block, is an ultrasound-guided fascial plane block, described in 2023 by Tulgar and colleagues, that provides analgesia for thoracic and breast surgery.
Quadratus lumborum block
The quadratus lumborum block is an ultrasound-guided fascial plane block injecting local anesthetic near the quadratus lumborum muscle to relieve pain after abdominal and hip surgery.
Rectus sheath block
The rectus sheath block is a fascial plane nerve block that numbs the anterior abdominal wall, used mainly for pain control after midline abdominal surgery such as hernia repair.
Scalp nerve block
A scalp nerve block is a regional anesthesia technique injecting local anesthetic around the scalp's sensory nerves, used for craniotomy pain and to blunt the hemodynamic response to skull pin fixation.
Serratus plane block
The serratus plane block (SAPB) is an ultrasound-guided chest wall nerve block, first described in 2013, used for pain relief after breast, thoracic, and rib-fracture surgery.
Subcostal transversus abdominis plane block
The subcostal transversus abdominis plane (SCTAP) block is an anesthesia technique that injects local anesthetic beneath the costal margin to numb the upper abdominal wall, used for surgery above the umbilicus such as cholecystectomy.
Superficial cervical plexus block
The superficial cervical plexus block is a regional anesthesia technique that numbs the skin of the neck by injecting local anesthetic near the cervical plexus, used most often for awake carotid endarterectomy.
Supraclavicular brachial plexus block
The supraclavicular brachial plexus block, or supraclavicular block, is a regional anesthesia technique injecting local anesthetic above the clavicle to numb the arm and shoulder.
Suprascapular nerve block
A suprascapular nerve block (SSNB) is a regional anesthesia procedure injecting local anesthetic near the suprascapular nerve, which carries about 70% of shoulder sensation, to relieve shoulder pain.
