Six (1.2%) of 501 patients sustained
phrenic nerve injury during operation for congenital heart disease
at our institutions between 1992 and 1998. The diagnosis was
confirmed by percutaneous stimulation of the phrenic nerve. All
but 1 patient were less than 9 months old, and the average weight
was 3.6kg. All 6 patients underwent diaphragmatic plication and
were extubated by 7 days after operation. Percutaneous stimulation
of the phrenic nerve allowed direct assessment of phrenic nerve
function which was difficult to detect by clinical and radiological
evidence. This method can be non-invasively used at the bedside
to facilitate early and accurate diagnosis of phrenic nerve palsy.
