Neck/Abdomen Flashcards
what forms the cervical plexus
the anterior rami of the first four cervical vertebrae C1-C4
4 cutaneous branches of cervical plexus
lesser occipital
greater auricular
transverse cervical
supraclavicular nerves
3 main motor branches of cervical plexus
phrenic nerve
ansa cervicalis nerves
an unnamed branch to the posterior neck muscles
what is cervical plexus block indicated for
unilateral neck surgery
The superficial cervical plexus block targets the____________ branches of the plexus
cutaneous
provide analgesia following thoracic and upper abdominal surgery and relief of pain associated with rib fractures, herpes zoster, and cancer
intercostal blocks
____________ blocks result in the highest blood levels of local anesthetic per local anesthetic dose injected of any nerve block procedure
intercostal
The intercostal nerves arise from
the dorsal and ventral rami of the thoracic spinal nerves.
Paravertebral blocks provide surgical anesthesia or postoperative analgesia for procedures involving
the thoracic or abdominal wall, mastectomy, inguinal or abdominal hernia repair, and more invasive unilateral abdominal procedures such as open nephrectomy or cholecystectomy
how many vertebral blocks does the paravertebral block usually cover
1-2 dermatomes above and below the level of injection
each spinal nerve emerges from
the intervertebral foramina
how far from each spinous process should the paravertebral block be placed
2.5 cm laterally
a pop/ loss of resistance may be felt as the needle passes thru the
costotransverse ligament
the erector spinae place block is useful for
surgery involving the thoracoabdominal wall, and it can provide analgesia for rib fractures.
nerves targeted in TAP block
subcostal (T12), ilioinguinal (L1), and iliohypogastric (L1)
