F. Bordet et al., TETRAPARESIS IN AN INFANT SUBSEQUENT TO L ONG-TERM ADMINISTRATION OF PANCURONIUM IN THE ICU, Annales francaises d'anesthesie et de reanimation, 14(5), 1995, pp. 426-428
Long-term administration of pancuronium for ventilatory support of adu
lts with ARDS may result in severe tetraparesis, with areflexia and at
rophy of distal muscles. This adverse effect occurs rarely in paediatr
ic intensive care units, We describe a case of tetraparesis after prol
onged pancuronium infusion in a 9-month-old girl who experienced a sev
ere bronchopneumonia caused by para-influenza virus, requiring endotra
cheal intubation and mechanical ventilation. To decrease chest wall ri
gidity, pancuronium was administered over 11 days, with a total dose o
f approximately 120 mg of pancuronium bromide. The day after discontin
uation of the muscle relaxant she had a severe tetraplegia with arefle
xia, but normal head movements. Electromyography showed a normal neuro
muscular transmission. She recovered from tetraplegia three months lat
er, Other causes of peripheral neuropathy were eliminated, Electroence
phalograms and head CT-scans were normal. The recovery pattern observe
d in our patient corresponded to the process of regeneration seen afte
r axonal degeneration. It is suggested that these neuromuscular compli
cations were caused by prolonged high-dosage pancuronium treatment, as
sociated with corticosteroid and aminoglycoside administration.
