Truncal blocks Flashcards
A pectoralis 2 nerve block targets the fascial plane between the:
a. pectoralis major and pectoralis minor muscles
b. medial pectoralis and lateral pectoralis nerves
c. pectoralis minor and serratus anterior muscles
d. serratus anterior and latissimus dorsi muscles
a. pec major & pec minor & c. pec minor and serratus anterior muscles
What is the objective of the serratus anterior plane block.
targets the axillary region (not the chest)
What is the objective of the PECS 1 & PECS 2 block?
Pecs blocks are interfascial plane blocks that provide anesthesia and/or analgesia to the anterior chest wall without the risks of paravertebral or intercostal blockade
Indications for performing the PECs blocks include
breast surgery, thoracotomy, and insertion of a port-a-cath, AICD, or subpectoral prosthesis
Indications for performing the serratus anterior block is
breast reconstruction with latissimus dorsi flap
The local anesthetic volume for the PECS 1 block is
10-15 mL
The local anesthetic volume for the PECS 2 block is
10-15 mL
The local anesthetic volume for the serratus anterior block is
20 mL
Complications of the pecs 1 & pecs 2 blocks include
failure to appreciate the thoracoacromial artery may lead to inadvertent puncture, vessel injury, hematoma, and LAST
Key nerves that innervate the chest include
thoracic intercostal nerve
lateral pectoral nerve
medial pectoral nerve
long thoracic nerve
thoracodorsal nerve
The origin of the thoracic intercostal nerve is the
ventral rami of spinal nerves (T1-T6)
The regions innervated by the thoracic intercostal nerve include
the intercostal muscles
cutaneous regions of the chest & breast
The origin of the lateral pectoral nerve is the
brachial plexus (C5-C7)
The regions innervated by the lateral pectoral nerve include
pectoralis major
The origin of the medial pectoral nerve is the
brachial plexus (C8-T1)
The regions innervated by the medial pectoral nerve include
pectoralis minor
lower region of pectoralis major
