OBJECTIVE: To investigate the risk factors of postoperative elevated blood pressure (BP) in children with childhood obstructive sleep apnea syndrome (OSAS) after adenotonsillectomy (AT).
STUDY DESIGN: Case series with planned data collection.
SETTING: Tertiary referral center.
METHODS: Two hundred forty-five consecutive children (180 boys and 65 girls, median age 6.6 years) with polysomnography-diagnosed OSAS who underwent AT between January 2010 and August 2019. Clinical, polysomnographic, and evening BP data were assessed preoperatively and postoperatively (≥3 months after AT). Changes in the variables before and after AT and between individuals with and without hypertension were compared.
RESULTS: Postoperatively, the median (interquartile range) apnea-hypopnea index significantly decreased from 10.4 (5.3-22.6) to 2.2 (1.0-3.8) events/h. In addition, the mean (standard deviation) evening diastolic BP z-score significantly decreased from 0.7 (0.94) to 0.5 (0.81) in the overall cohort, and both systolic (2.1 [0.94]-1.0 [1.31]) and diastolic BP z-scores (1.6 [0.98]-0.7 [0.85]) significantly decreased in the preoperative elevated BP subgroup. Multivariate logistic regression analysis showed that preoperative obesity (adjusted odds ratio = 4.36, 95% confidence interval = 2.24-8.49) and mean peripheral oxygen saturation <95% during sleep (adjusted odds ratio = 2.73, 95% confidence interval = 1.29-5.79) were independently associated with postoperative elevated BP.
CONCLUSION: Preoperative obesity and mean peripheral oxygen saturation <95% during sleep were significantly associated with postoperative elevated BP in the children with OSAS, further indicating the importance of careful BP monitoring in this subgroup despite AT treatment.
