DISCUSSION<br />
Tracheal <strong>rupture</strong> has been reported as a rare compli-<br />
cation of endo<strong>tracheal</strong> <strong>in</strong>tubation <strong>in</strong> both adults (1-6)<br />
<strong>an</strong>d children (7-16). Direct trauma dur<strong>in</strong>g <strong>in</strong>tubation<br />
may result from the endo<strong>tracheal</strong> tube, the stylet or<br />
the laryngoscope. Most cases m<strong>an</strong>ifest with subcut<strong>an</strong>eous<br />
emphysema, respiratory distress <strong>an</strong>d pneumothorax.<br />
But, as <strong>in</strong> our case, <strong>tracheal</strong> <strong>rupture</strong> with the<br />
creation of a false passage may result <strong>in</strong> the <strong>in</strong>ability<br />
to ventilate, rapid respiratory failure <strong>an</strong>d death. In<br />
their review of the literature, Doherty <strong>an</strong>d colleagues<br />
reported a very high case fatality rate of 75% <strong>in</strong> 8<br />
neonatal cases compared with only 9% <strong>in</strong> 35 adult<br />
cases (8).<br />
Typically, <strong>in</strong> adults the lacerations occur <strong>in</strong> the pos-<br />
terior membr<strong>an</strong>ous part of the trachea (3, 4, 17). In<br />
contrast, the area of <strong>tracheal</strong> <strong>in</strong>jury <strong>in</strong> neonates more<br />
commonly <strong>in</strong>volves the <strong>an</strong>terior wall <strong>in</strong> the subglottic<br />
or <strong>tracheal</strong> region (8, 10, 14, 15). Doherty <strong>an</strong>d<br />
colleagues have speculated that the neonatal trachea<br />
maybe more vulnerable due to the higher elasticity of<br />
the immature cartilage <strong>an</strong>d weakness of the <strong>in</strong>ter-cartilag<strong>in</strong>ous<br />
membr<strong>an</strong>e (8). Additional risk factors (2, 5,<br />
6, 11) that have been associated with <strong>tracheal</strong> <strong>in</strong>jury<br />
dur<strong>in</strong>g <strong>in</strong>tubation are listed <strong>in</strong> the Table.<br />
This tragic case has prompted us to review our <strong>in</strong>tu-<br />
bation procedure <strong>in</strong> <strong>preterm</strong> neonates. In our <strong>in</strong>stitu-<br />
tion, delivery of <strong>extremely</strong> <strong>preterm</strong> <strong>in</strong>f<strong>an</strong>ts are always<br />
attended by two experienced neonatologists. A naso-<br />
