Insights
Childhood obesity may not require inpatient care after adenotonsillectomy, but increased oxygen monitoring is crucial during initial recovery for these patients.
Area of Science:
- Pediatric Surgery
- Obesity Medicine
- Anesthesiology
Background:
- Post-adenotonsillectomy complications can impact patient recovery.
- Childhood obesity is a growing concern with potential implications for surgical outcomes.
- Current guidelines for postoperative management may not fully address the needs of obese pediatric patients.
Purpose of the Study:
- To investigate the association between childhood obesity and complications following adenotonsillectomy.
- To inform evidence-based guidelines for the postoperative care of pediatric patients undergoing adenotonsillectomy, particularly those with obesity.
Main Methods:
- Retrospective review of 707 pediatric adenotonsillectomy cases from 2020.
- Analysis of complications in the recovery unit and within two weeks of discharge.
- Obesity defined as body mass index at or above the 95th percentile; severe obesity at the 99th percentile.
Main Results:
- Patients with obesity were 1.65 times more likely to require supplemental oxygen in the recovery unit.
- Obese patients experienced significantly lower postoperative oxygen saturation nadirs.
- No significant differences in other complication rates or post-discharge returns were observed between obese and non-obese cohorts.
Conclusions:
- Childhood obesity alone, without other comorbidities, may not necessitate routine inpatient admission post-adenotonsillectomy.
- Enhanced monitoring for oxygen desaturation is recommended for obese patients in the initial recovery phase.
- Further prospective research is needed to fully elucidate postoperative management strategies for this population.
Objectives:
To evaluate associations between childhood obesity and post-adenotonsillectomy complications, informing guidelines for postoperative management.
Methods:
The retrospective review assessed outpatient pediatric tonsillectomy/adenoidectomy cases performed at 2 ambulatory surgery centers in 2020. Complications in the recovery unit and within 2 weeks of surgical discharge were reviewed along with clinical and demographic variables. Obesity was defined as sex-specific body mass index-for-age, or weight-for-age if height data were unavailable, at/above the 95th percentile. The 99th percentile served as the threshold for severe obesity. Analyses used Chi-square/Fisher's exact tests and independent-samples t-tests with relative risk or effect sizes.
Results:
The review included 707 cases (180 patients with obesity). Overall incidence of complications in the recovery unit was 9.1%. Patients with obesity were significantly more likely to require supplemental blow-by oxygen (P = .02); relative risk was 1.65 (95% CI: 1.16-2.35) times greater in the cohort with obesity. Obesity had a small effect on postoperative oxygen saturation nadirs, which were significantly lower among patients with obesity (d = -0.34; P < .001). No differences emerged between cohorts with and without obesity in the incidence of any other complications before or after surgical discharge. Overall incidence of post-discharge returns was 7.9%. Incidence of complications did not vary by obesity severity.
Conclusion:
From this cohort, childhood obesity without other significant comorbidities may not warrant routine inpatient care following adenotonsillectomy. Patients with obesity should receive additional monitoring for oxygen desaturation events during the first hours of recovery. Further prospective studies should continue to address this important topic.
