Case Reports[A possibility of central diffusion during stellate ganglion blockade: "the sheath of the spinal rachidian nerve"].
Stellate ganglion block is a common treatment for neuropathic pain. The technique is not without potentially severe complications when a paratracheal approach is used. A 33-year-old woman complained of atypical facial pain of 15 years' duration with pain intensity of 6 to 8 on a visual analog scale and no pain-free periods upon use of inadequate analgesia. ⋯ Central spread of a portion of local anesthetic by way of the spinal nerve sheath toward the subarachnoid space may cause partial cervical and basal nuclear blockade. Signs would be apnea, involvement of the upper extremities and facial muscles, although paresthesia during the injection is the only evidence supporting this hypothesis. Bone contact and negative aspiration while performing a stellate ganglion block do not guarantee avoidance of complications.

Randomized Controlled Trial Comparative Study Clinical Trial[Efficacy of EMLA cream, effect of time and place of application].
To evaluate the anesthetic efficacy of EMLA cream for alleviating pain associated with puncture and pressure in areas where venous catheters are normally inserted. ⋯ The efficacy of EMLA cream varies demonstrably depending on type of stimulus, site of application and time since application.
