A retrospective study of 30 patients who met the clinical criteria for saphenous nerve entrapment at the adductor canal is described. Patients experienced symptoms, usually anterior knee pain, for an average of 36 +/- 7 months. Each patient received an average of 1.9 +/- 0.4 saphenous nerve blocks at the adductor canal during treatment. ⋯ Age, medications taken, number of blocks performed, and length of followup were unrelated to outcome. Length of symptoms did significantly correlate with final pain level (r = 0.39, P less than 0.05). The diagnosis of this syndrome, description of the saphenous nerve block at the adductor canal, and the possible etiology are presented.

Fifty-four patients developed severe intercostal neuralgia a few weeks after sternotomy. Immediate relief afforded by parasternal nerve blocks confirmed that the pain derived from scar-entrapped neuromas of the anterior rami of the first 4-6 intercostal nerves in the upper (and mainly left) interchondral spaces after insertion of the sternal wires. Permanent relief (i.e., over 6 months) followed repeated bupivacaine blocks in 57.4% of the patients, phenol blocks in another 22.2%, and alcohol blocks in a remaining 9%. Treatment was successful in 87% of the patients.

Severe hypotension and bradycardia occurred in two patients after superior laryngeal nerve block for awake tracheal intubation. Both patients required treatment with anticholinergic drugs and i.v. infusions and made a good recovery.
