Abstract

To compare the nocturnal oxygen saturation profiles of children with adenotonsillar enlargement with that of normal children. A 1 year comparative study. The study was carried out at the Otorhinolaryngology Ward of the University College Hospital Ibadan. These comprise of 60 children (1-9 years) with clinically confirmed adenotonsillar enlargement admitted for adenotonsillectomy and 60 normal children matched for age and sex. The biodata and common clinical presentations of the study group were acquired with a structured proforma. The severity of nasopharyngeal obstruction was determined by the adenoidal-nasopharyngeal ratio while the degree of tonsillar enlargement was graded by the Brodsky's classification. The nocturnal oxygen saturation of all the participants were recorded with a wrist worn pulse oximeter. Recording was for at least for 4 h. Oxygen saturation <92 % was regarded as desaturation. The oximetric values of the study and control group were compared. The mean nocturnal SPO2 (peripheral saturation of oxygen) profiles of children with adenotonsillar enlargement were as follows: basal = 96.86 %, minimum = 84.99 %; maximum = 99 % and average SPO2 <92 % = 87.74 % while the saturation profiles of the control group were as follows; basal = 97.88 %, minimum = 89.71 %; maximum = 99 %, average SPO2 <92 % = 90.82 %. Normal children have better nocturnal saturation profiles than children with adenotonsillar enlargement.

Keywords: Adenotonsillar enlargement; Oxygen desaturation index; Pulse oximetry; SPO2.
