Obstructive sleep apnea (OSA) in children, characterized by hypoventilation
secondary to upper airway obstruction, often results from tonsil and adeno
id hypertrophy. Adenotonsillectomy is the standard therapy in this patient
population. The immediate postoperative period is complicated occasionally
by respiratory difficulties that may require intubation and mechanical vent
ilation. Recently, physicians have provided temporary airway support using
continuous and bilevel positive airway pressure (BiPAP) devices. Reported c
omplications of positive airway pressure devices include local abrasions to
the nose and mouth; dryness of the nose, eyes, and mouth; sneezing; nasal
drip, bleeds, and congestion; sinusitis; increased intraoccular pressure; n
on-compliance; and pneumocephalus. Subcutaneous emphysema following facial
trauma, dental extractions, adenotonsillectomy, and sinus surgery has been
reported. There is also a hypothetically increased risk of subcutaneous emp
hysema following the use of positive airway pressure ventilation in the ton
sillectomy patient. Between January 1997 and July 1998, 1321 patients under
went tonsillectomy and/or adenoidectomy at our institution. In reviewing th
e records of all pediatric intensive care unit admissions during that time
period, we identified nine patients, of the 1321, who required BiPAP postop
eratively. Of these, four children were obese, four had preexisting neurolo
gical disorders, and one underwent endoscopic sinus surgery and adenoidecto
my. Three children were asthmatic, and three were less than 3 years of age.
Two obese children were discharged with home BiPAP, one of whom had been o
n BiPAP prior to surgery. All patients tolerated BiPAP without complication
s. This]preliminary report suggests that BiPAP is a safe and effective meth
od of respiratory assistance in the adenotonsillectomy patient with preexis
ting conditions who is predisposed to postoperative airway obstruction. Fur
thermore, with BiPAP, the risks of intubation and ventilator dependence are
avoided. (C) 1999 Elsevier Science Ireland Ltd. All rights reserved.
