patient selection for transtracheal block
any patient is a candidate in whom it is desirable to avoid the valsalva-like straining that may follow awake tracheal intubation.
potential problems of the transtracheal block
this block can result in coughing. - should be considered in patients in whom coughing is clearly undesirable.
what should you ask the patient to do during transtracheal block
forcefully exhale- this forces the patient to initially inspire before coughing-making distal airway anesthesia predictable
what nerves are being anesthetized in translaryngeal block
vagus nerve and recurrent nerve
when delivering a superior laryngeal block where should the hyoid be
the anesthesiologist should displace the hyoid bone toward the side to be blocked by grasping it between the index finger and the thumb
is it safe to preform a bilateral deep cervical plexus block. eplain
no, the phrenic nerve may be partially blocked with this technique.
potential problems with the deep cervical plexus block
accompanied by at least partial phrenic nerve block
what muscle is being blocked during a retrobulbar block
orbicularis occult muscle.
why is occipital nerve block performed
diagnoses and treatment of occipital neuralgia.
what must you ask the patient prior to occipital block
has the patient undergone any posterior cranial surgery- total spinal anesthesia has occurred after occipital nerve block in patients who have had such surgery
when is trigeminal ganglion block most commonly performed
diagnostic block before trigeminal neurolysis in patients with facial neuralgia.
name some potential problems with trigeminal ganglion block
subarachnoid injection of la
hematoma formation
painful-needs effective sedation
maxillary nerve (V2) when is it most commonly used
diagnose and workup facial neuralgia.
after maxillary nerve block what can patients develop
a black eye
mandibular block (v3)
mixed motor sensory nerve- facial neuralgia.
