Screening for Pediatric Obstructive Sleep Apnea before Ambulatory Surgery.

PURPOSE: The American Society of Anesthesia practice guidelines recommend that pediatric and adult patients who undergo ambulatory surgery be screened for obstructive sleep apnea (OSA). With this in mind, our objective was to assess the frequency of screening by anesthesia providers for the signs and symptoms of OSA in children undergoing surgery in an ambulatory setting. METHODS: Prospective single-blinded observational study of anesthesia providers' preoperative interview of caregivers of consecutive patients younger than age 18 who were scheduled for ambulatory surgery. RESULTS: One hundred one children (30 females) were identified, with a mean age of 6.9 ± 5.0 years; 54 were classified as white, 33 as black, and 14 as other. Total OSA-18 scores ranged from 18 to 97, with a mean of 33.1 ± 14.8. The mean score for adenotonsillectomy patients was higher than that for children who underwent procedures other than adenotonsillectomy. Thirty-one percent of children were screened for OSA, and snoring was the most common symptom recorded (28%). Patients who were screened for OSA were more likely to have snoring (p < 0.001), known OSA (p = 0.006), and a scheduled adenotonsillectomy (p = 0.02). CONCLUSION: OSA was not routinely screened for by anesthesia providers prior to ambulatory pediatric surgery. When screening did occur, "snoring" was the most commonly recorded symptom. Paradoxically, patients with undiagnosed OSA who would benefit the most from screening were the least likely to be screened.

Does surgery for obstructive sleep apnea improve depression and sleepiness?

OBJECTIVES/HYPOTHESIS: To determine if surgical intervention for OSA (obstructive sleep apnea), particularly multilevel surgery, decreases depression and sleepiness. STUDY DESIGN: Prospective cohort study. METHODS: Chart and prospective outcome database review of patients who underwent surgery from August 2008 through November 2012. Patients were evaluated before and after surgery using the Epworth Sleepiness Scale (ESS), the Beck Depression Index (BDI), and overnight polysomnography. RESULTS: Forty-four patients (12 females; 32 males) met inclusion criteria. Mean age of participants was 44.0 years (SD, 10.2); mean body mass index was 31.9 (SD, 9.3). The mean preoperative obstructive respiratory disturbance index (RDI) was 35.8 events/hour (SD, 21.9; range, 6.6-94.2), which decreased to 17.1 (SD, 19.5; range, 0.8-78.1; P < 0.0001). Mean ESS improved from 10.8 (SD, 4.7) to 6.3 (SD, 3.7; P = 0.0001); whereas BDI scores improved from 8.4 (SD, 8.2) to 4.9 (SD, 6.0; P = 0.0051). There were 22 (50.0%) patients with excessive daytime sleepiness and 12 (27.3%) patients with depression before surgery. Surgery was associated with resolution of sleepiness in 17 patients (77.3%) and depression in 9 patients (75.0%). In multivariable regression analysis, only change in ESS (P = 0.003) and baseline BDI (P < 0.001) were associated with improvement in depression. RDI was not significant (P = 0.15). CONCLUSIONS: Surgical treatment of OSA, especially multilevel surgery, resulted in significantly reduced depression, with resolution in 75% of patients. Similarly, surgery resulted in significantly reduced sleepiness, with resolution in 77% of patients. Reduction in sleepiness scores, but not OSA severity, was predictive of improvement in depression scores. Further evaluation with a larger sample size and a control group is warranted.
