Objective: Identify incidence and factors associated with respiratory complications after type 1 cleft repair., Methods: Retrospective chart review of patients who underwent cleft repair over a 5-year period performed by a single surgeon. Primary endpoint was respiratory complications (oxygen desaturation <90%). Fisher's exact test was used to identify differences between repair types (endoscopic carbon dioxide laser-assisted repair and injection laryngoplasty). Logistic regression was used to identify predictors of respiratory events., Results: Fifty-five patients were included. Thirty-four (62%) patients underwent endoscopic carbon dioxide laser-assisted repair and 21 (38%) underwent injection laryngoplasty. Average hospital stay for each group was 1.6 days (SD = 3.1) and 0.6 days (SD = 0.9), respectively. Desaturations occurred in three patients (9%) in the laser-assisted repair group and one patient (4%) in the injection group. All occurred within 3 h after surgery and resolved with supplemental oxygen, oral airway placement, and/or mask ventilation. Two affected patients had comorbid diagnosis of asthma (one had poor medication compliance), and one had a history of developmental delay and hypotonia. In the injection group, desaturations occurred in one patient with a history of tracheal stenosis and double aortic arch. No correlation existed between repair type and desaturation (p = 0.57). No variables were significant predictors of events., Conclusions: In this cohort, respiratory events after type 1 laryngeal cleft repair occurred early in the postoperative period, in children with cardiac and pulmonary comorbidities. This suggests postoperative admission may only be necessary for a select group of patients undergoing type 1 cleft repair. However, further research is needed to determine criteria for same-day discharge., Competing Interests: Declaration of competing interest None., (Copyright © 2019. Published by Elsevier B.V.)

Study Objectives: Postoperative respiratory complications (PRCs) are common among children with obstructive sleep apnea (OSA) after adenotonsillectomy. We analyzed postoperative admission guidelines to determine which optimally balanced patient safety and cost., Methods: Retrospective study of children aged 12 years or younger undergoing adenotonsillectomy for OSA after polysomnography at a tertiary academic care center over 2 years. Demographics, medical History, and hospital course were collected. Advanced Excel modeling was used to assess the number of children with PRCs identified with guideline admission criteria and to validate the significance of these findings in our patient population with logistic regression., Results: Six hundred thirty children were included; 116 had documented PRCs. Children with PRCs were younger ( P = .024) and more frequently male ( P = .012). There were no significant differences in race ( P = .411) or obesity ( P = .265). More children with PRCs had an apnea-hypopnea index (AHI) > 24 events/h ( P < .001). Following guidelines from the American Academy of Pediatrics, American Academy of Otolaryngology - Head and Neck Surgery, and Nationwide Children's Hospital, 82%, 87%, and 99% of children with PRCs would be identified, costing $535,962, $647,165, and $1,053,694 for admission, respectively. Using a non-validated, forced model to refine predictors described in published guidelines, our model would have identified 95% of children with one or more PRCs, with a moderate cost., Conclusions: Current admission guidelines attempt to identify children with OSA at high risk for PRCs after adenotonsillectomy; however, none consider the economic cost to the health care system. We present a comparison of the number of patients identified with PRCs after adenotonsillectomy and the cost of expected admissions using currently published guidelines., Commentary: A commentary on this article appears in this issue on page 1371., (© 2017 American Academy of Sleep Medicine)

Background: Children who undergo adenotonsillectomy for sleep-disordered breathing frequently have postoperative oxygen desaturations. Nocturnal hypoxia has been shown to predict postoperative respiratory complications; however, other gas exchange abnormalities detected on polysomnography (PSG) have not been evaluated., Aim: We sought to determine whether hypercapnia seen on preoperative nocturnal PSG can predict postoperative hypoxemia., Methods: We conducted a retrospective review of 319 children who underwent polysomnography before adenotonsillectomy. Saturation levels were recorded for at least 2 h postoperatively, and the primary outcome was desaturation (<90%)., Results: The median patient age was 5 years (range, 5 months-17 years). Patients who desaturated postoperatively had higher median peak endtidal CO2 (EtCO2 ) levels (55.5 vs 52 mmHg; P = 0.02), lower saturation nadirs (80.5% vs 88%; P = 0.048), and were younger (2 vs 6 years; P < 0.001) than those without desaturation. Age was significantly correlated with peak EtCO2 (r = -0.16), respiratory disturbance index (RDI; r = -0.23), and oxygen saturation nadir (r = 0.25; all P < 0.01). In unadjusted analysis, age <3 years compared to ≥9 years (odds ratio [OR] = 10.09; 95% confidence interval [CI] = 2.13-96.26), peak EtCO2  > 55 mmHg (OR = 3.38; 95% CI = 1.21-9.47), and RDI ≥ 10 (OR = 2.89; 95% CI = 1.05-8.42) were associated with increased odds of desaturation. Multivariable logistic regression on age, race, sex, peak EtCO2 , RDI, opioid use, and saturation nadir showed that only age was significantly associated with postoperative desaturation. Patients 0-2 years old were 10.43 (95% CI = 1.89-110.9) times more likely to have desaturation than patients 9-17 years old., Conclusion: Patients <3 years of age are most likely to have postoperative hypoxemia after adenotonsillectomy. Gas exchange abnormalities did not correlate with postoperative desaturations, although age and peak EtCO2 did strongly correlate., (© 2015 John Wiley & Sons Ltd.)
