Anesthesia Key

Key Points • Quadratus lumborum (QL) block is a novel approach for managing postoperative pain in patients undergoing abdominal and hip surgeries. • The sensory dermatomal coverage of the QL…

Key Points • The subcostal transversus abdominal plane (TAP) approach is very useful for supraumbilical procedures. • The most cephalad sensory dermatomal spread is T8. • The bilateral continuous catheter…

Key Points • The transversus abdominis plane (TAP) block is a tissue plane block depending on adequate spread of local anesthetics through the plane—accordingly a minimum volume of 20 mL…

Key Points • A high-frequency transducer is preferred for this block. • The rectus sheath block provides periumbilical somatic analgesia from the levels T9–T11 and is used for surgeries involving…

KEY POINTS • The erector spinae plane block (ESPB) is actually used for acute and chronic thoracoabdominal pain syndromes, although its indication has been described for the treatment of pain…

Key Points • The thoracic paravertebral block, with or without catheter, can be used in lieu of thoracic epidural catheter for unilateral procedures and for breast surgeries. • Pneumothorax is…

Key Points • Thoracic and lumbar somatic innervation extends from the chest and axilla to the toes. • Paravertebral block has an advantage over neuraxial block in its ability to…

Key Points • A high-frequency transducer is preferred for this block due to the shallow nature of the cervical plexus. • This approach is for the superficial cervical plexus nerve…

Key Points • Anterior chest wall blocks are used as alternatives to thoracic epidurals and paravertebral blocks for breast surgeries and procedures involving the anterior chest walls. • Serratus plane…

Key Points • Intercostal nerves supply major parts of the skin and musculature of the chest and abdominal wall. • Intercostal nerve block is now commonly performed for treatment of…
