Polymyxin flushes for endotracheal tube suction catheters in extremely low birth-weight infants: Any benefit in preventing ventilator-associated events?

We report that receipt of polymyxin B endotracheal tube suction catheter flushes did not reduce the incidence of pediatric ventilator-associated events (PedVAE) in infants weighing <1,000 g in this retrospective study. Incidence of PedVAE in our group of extremely low birth-weight infants was 6 per 1,000 ventilator days.
