Upper and Lower PNBs Flashcards
Blocking this nerve may help allow you to place a tourniquet on the arm of an awake patient
Intercostobrachial nerve (Arises from T2 and is blocked with a field block)
Inter scalene targets these roots
C5, 6, and 7 (the stoplight)
What does inter scalene block?
Blocks the upper trunk! So it’s good for shoulder and upper arm procedures. Not great for lower arm procedures because it blocks the lower roots that innervate the hand and forearm.
The cupola of the lung is higher on which side?
Right side
S/S of Horner’s syndrome?
Horny Pam!
Ptosis, anhidrosis, and miosis.
As little as ___mL in the vertebral artery can result in sz activity
1mL
Horner’s syndrome occurs as a result of what?
Blockade of the stellate ganglion (located at C7). Indicates successful block.
Pneumothorax may have occurred if pt complains of
Coughing or chest pain during needle insertion or manipulation
Complications of inter scalene block
Horner's syndrome Phrenic Nerve Paralysis RLN Injury Pneumothorax Epidural/Spinal injection Seizure Bezold jarisch reflex
What is the Bezold Garish Reflex?
Will see bradycardia and hypotension!
Venous pooling results in a profoundly undefiled ventricle. The heart slows to improve diastolic filling.
Doing this pre-op and decrease the risk of BJR
Pre-op beta blockade
Supraclavicular is good for
Surgeries at or below the elbow
Complications of supraclavicular block
Pneumo
Horner’s Syndrome
Subclavian artery injection
Infraclavicular block is good for
surgeries below the elbow
Infraclavicular block will block this part of the plexus
