[Intrabronchial diffusion of amoxycillin when administered by two different injection modes (author's transl)].
Twelve ICU patients, all with broncho-pulmonary infection were treated with 50 mg/kg-1/24 h-1 of amoxycillin administered every eight hours, either by one hour perfusion, or by brief IV injection (2'). Both modes were given to all of the patients in order to determine, by comparison, the most efficient treatment. There is no significant difference in serum levels after perfusion or IV injection. However, IV injection is preferable because of a significant difference in bronchial levels after 3 hours (p less than 0.01). In most cases, the bronchial levels and the bronchio/serum concentration ratios, while not significantly different, are higher than after perfusion. None of the results justify the use of perfusion.
