To determine whether the pathogenesis of lower airway colonization and infection was endogenous (via the oropharynx) or exogenous (via the endotracheal tube or tracheotomy) during the 2 modes of ventilation in the same subset of children requiring long-term ventilation. ⋯ Surveillance samples allow the distinction between primary endogenous ("imported" bacteria) from secondary endogenous and exogenous ("nosocomial" microorganisms) colonization and infection. This classification permits the development of preventive strategies to control both endogenous and exogenous pathways.

To determine the incidence of perioperative anesthesia complications during bilateral myringotomy with tympanostomy tube placement (BMTT). ⋯ Anesthesia administered for placement of tympanostomy tubes by physicians who specialize in the care of children in a tertiary care children's hospital is safe. The most significant predictor of a minor anesthetic event during BMTT is the presence of a preexisting medical condition or concurrent acute illness.
