Middle ear effusions in neonates.

Suppurative middle ear effusions (MEE) have been shown to occur commonly in neonates. In spite of this, otoscopy is not routinely performed on septic infants in the neonatal intensive care unit (ICU). This is clinically significant since unrecognized suppurative MEE may act as a focus for dissemination of bacteria into the circulation and/or central nervous system (CNS). We have completed a prospective study in an attempt to define the prevalence, bacteriology, and response to therapy of MEE in neonates. To facilitate this, the normal micro-otsocopic appearance of the newborn TM was established by systematically examining 50 normal infants under 24 hours old. MEE was present in 30% of 125 consecutively examined infants in the neonatal ICU. Bacteriologic data are drawn from tympanocentesis performed on 34 neonates. Nasotracheal intubation of longer than seven days is highly associated with suppurative MEE. Suppurative MEE in the neonatal ICU is often refactory to treatment and may require prolonged therapy and repeated tympanocentesis.

Otitis media in the neonatal intensive care unit.

Thirty-eight of 125 premature infants who were hospitalized in a neonatal intensive care unit (NICU) had abnormal tympanic membrane mobility compatible with otitis media. Twenty-five of these 38 had received antibiotics within one week of otoscopic examination and were considered to have either serous otitis or partially treated bacterial otitis media; tympanocentesis was not performed in them. Tympanocentesis was performed in the remaining 13 infants who had not received antibiotics. Bacterial otitis media was confirmed in ten of the 13. Either staphylococcal (six cases) or Gram-negative enteric organisms (four cases) were isolated in cultures obtained by tympanocentesis in these cases. The four cases of Gram-negative infections occurred in infants within six weeks of birth. Nasotracheal intubation for more than seven days was significantly correlated with impaired tympanic membrane mobility compatible with otitis media. Otitis media occurs frequently among premature infants who are hospitalized in an NICU, and it should be looked for in any infant in whom sepsis is clinically suspected.

Sterile preparation of the external auditory canal with povidone-iodine.

Sterile preparation of the external auditory canal is usually not undertaken, although the external auditory canal provides surgical access for several procedures involving the tympanic membrane, middle ear, and vesibule. This is due to the rarity of postoperative wound infections, as well as difficulty in sterilizing the external auditory canal. Four antiseptic solutions commonly used for operative preparation were tested to determine thrir potential for sterilizing the external auditory canal. Povidone-iodine solution was effective in sterilizing 90% of the external auditory canals of children and adults. This simple technique may find clinical use in surgical procedures involving the external auditory canal.
