Saphenous nerve evoked potentials and the assessment of intraabdominal lesions of the femoral nerve.

A technique for recording somatosensory evoked potentials after stimulation of the patellar branch of the saphenous nerve is described and the results from 11 normal subjects and from two patients with intraabdominal femoral nerve injuries are presented. One patients developed a nerve lesion after an abdominal surgical procedure and the second suffered a gunshot wound causing femoral nerve paralysis. Both patients recovered spontaneously. Evoked potentials from saphenous nerves showed a significant discrepancy between faster motor recovery and delay in reinstating sensory axonal conduction.

A comparison of amiodarone and digoxin in the treatment of atrial fibrillation complicating suspected acute myocardial infarction.

Thirty-four patients with atrial fibrillation complicating suspected acute myocardial infarction were randomised to treatment with intravenous amiodarone (n = 18) or intravenous digoxin (n = 16). After 24 h, similar proportions of patients in each group had reverted to sinus rhythm. However, there was a tendency towards earlier reversion with amiodarone. At 4 h, 72% of the amiodarone group had reverted to sinus rhythm, compared with 31% of the digoxin group (p less than 0.1). This tendency was more marked in patients with definite infarction (at 4 h, amiodarone 75% reversion, digoxin 10% reversion). Neither drug had a significant effect on blood pressure. Atrial fibrillation may cause serious haemodynamic deterioration in acute myocardial infarction. In comparison with digoxin, amiodarone offers more rapid control of the ventricular response rate and may, in addition, restore sinus rhythm more rapidly.
