Peripheral O2 Saturation change in adenotonsillar hypertrophy

One of the obstructive complications of Waldeyer's ring hypertrophy is changing in Arterial O2 saturation which could result in serious complications such as corpulmonal and hypertension and even sudden infant death syndrome. Because this complication is common we decided to study it. In this analytic cohort study forty patients who were admitted for Adenotonsilecomy in Mashhad University hospitals at ENT Departments were selected, and their changing O2 saturation studies were recorded with pulseoxymeter along the one hour normal sleep. This change was compared with a control group. The result shows that there is a significant difference between the two groups
