Sleep apnea-specific hypoxic burden and pulse rate response in children using high flow nasal cannula therapy compared with continuous positive airway pressure. Sleep Med 2024; 124:187-190. [PMID: 39316929 DOI: 10.1016/j.sleep.2024.09.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2024] [Revised: 09/16/2024] [Accepted: 09/19/2024] [Indexed: 09/26/2024]
Abstract
BACKGROUND Elevated sleep apnea-specific hypoxic burden (HB) and pulse rate response (ΔHR) are associated with a higher cardiovascular risk in adults. The clinical significance of HB and ΔHR in children with obstructive sleep apnea (OSA) and their responses to therapy have not yet been investigated. This study aimed to compare the efficacy of high flow nasal cannula (HFNC) and continuous positive airway pressure (CPAP) in reducing HB and ΔHR in children. METHODS This analysis included 17 children (11 males, mean age: 12.6 ± 3.9 years) with obesity and/or medical complexity and moderate-to-severe OSA. Each participant underwent two additional sleep studies: one for HFNC titration and another for CPAP titration. HB and ΔHR were derived from the oximetry and pulse rate signals from overnight sleep studies, respectively. RESULTS Both HFNC and CPAP demonstrated significant reductions in HB from baseline, with similar magnitudes [HFNC: -129 (standard error, SE 55) %min/h, p = 0.003; CPAP: -138 (SE 53) %min/h, p = 0.005]. However, for ΔHR, a significant reduction from baseline was observed only in the CPAP group [-2.7 (SE 1.1) beats/min, p = 0.049], not the HFNC group [-1.0 (SE 1.4) beats/min, p = 0.67]. CONCLUSIONS HFNC is as effective as CPAP in treating hypoxia in children with OSA, but HFNC might be less effective than CPAP in mitigating cardiovascular stress from autonomic disturbances during obstructive events.

Abstract
BACKGROUND Polysomnography (PSG) is the gold standard for the diagnosis of pediatric sleep-disordered breathing (SDB). However, the literature characterizing the indications for inpatient PSGs and the impact on clinical decision-making is limited. OBJECTIVE To determine the indications, results, and outcomes for children undergoing inpatient PSGs at our institution. METHODS We performed a retrospective review of children aged 0-18 years who underwent inpatient diagnostic PSGs between July 2018 and July 2021 at SickKids, Toronto, Canada. Baseline characteristics, indications, and management were reviewed and characterized by descriptive statistics. RESULTS Eighty-eight inpatient PSGs were performed in 75 children (male 62.7%). Median (interquartile range) age and body mass index z-score were 1.5 (0.2, 10.8) years and 0.27 (-1.58, 2.66), respectively. The most common indication for inpatient PSG was initiation and titration of ventilation (n = 34/75, 45.3%). Of the 75 children, 48 (64%) had multiple complex chronic conditions (CCCs). Sixty children (80%) underwent a baseline PSG for either the entire night or a portion of the night. Of these studies, 54 (90%) had clinically significant SDB of which isolated obstructive sleep apnea (OSA; 17/60, 28.3%) was the most common. The following management was undertaken for the 54 patients with SDB; respiratory technology (88.9%), surgical intervention (31.5%), positional therapy (1.9%), intranasal steroids (3.7%), and no further intervention (5.6%), respectively. CONCLUSIONS Our study highlights that inpatient PSG was an important diagnostic tool resulting in directed medical and surgical management. Future multicenter studies are needed to compare indications for inpatient PSGs across institutions to develop evidence-based clinical practice guidelines.

Heated humidified high flow nasal cannula therapy in children with obstructive sleep apnea: A randomized cross-over trial. Sleep Med 2023; 107:81-88. [PMID: 37148831 DOI: 10.1016/j.sleep.2023.04.017] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 04/10/2023] [Accepted: 04/13/2023] [Indexed: 05/08/2023]
Abstract
OBJECTIVE/BACKGROUND Moderate-to-severe obstructive sleep apnea (OSA) is highly prevalent in children with obesity and/or underlying medical complexity. The first line of therapy, adenotonsillectomy (AT), does not cure OSA in more than 50% of these children. Consequently, continuous positive airway pressure (CPAP) is the main therapeutic option but adherence is often poor. A potential alternative which may be associated with greater adherence is heated high-flow nasal cannula (HFNC) therapy; however, its efficacy in children with OSA has not been systematically investigated. The study aimed to compare the efficacy of HFNC with CPAP to treat moderate-to-severe OSA with the primary outcome measuring the change from baseline in the mean obstructive apnea/hypopnea index (OAHI). PARTICIPANTS/METHODS This was a single-blinded randomized, two period crossover trial conducted from March 2019 to December 2021 at a Canadian pediatric quaternary care hospital. Children aged 2-18 years with obesity and medical complexity diagnosed with moderate-to-severe OSA via overnight polysomnography and recommended CPAP therapy were included in the study. Following diagnostic polysomnography, each participant completed two further sleep studies; a HFNC titration study and a CPAP titration study (9 received HFNC first, and 9 received CPAP first) in a random 1:1 allocation order. RESULTS Eighteen participants with a mean ± SD age of 11.9 ± 3.8 years and OAHI 23.1 ± 21.7 events/hour completed the study. The mean [95% CI] reductions in OAHI (-19.8[-29.2, -10.5] vs. -18.8 [-28.2, -9.4] events/hour, p = 0.9), nadir oxygen saturation (7.1[2.2, 11.9] vs. 8.4[3.5, 13.2], p = 0.8), oxygen desaturation index (-11.6[-21.0, -2.3] vs. -16.0[-25.3, -6.6], p = 0.5) and sleep efficiency (3.5[-4.8, 11.8] vs. 9.2[0.9, 15.5], p = 0.2) with HFNC and CPAP therapy were comparable between conditions. CONCLUSION HFNC and CPAP therapy yield similar reductions in polysomnography quantified measures of OSA severity among children with obesity and medical complexities.

Abstract
Children with medical complexity (CMC) are a diverse group of children affected by a spectrum of chronic disorders and physiologic abnormalities. Due to their underlying disorders, they disproportionately experience respiratory comorbidities and complications. Respiratory-related complications that arise in this population often begin subtly and progress over time and can result in lung injury, respiratory insufficiency, and eventual chronic respiratory failure. CMC make up a substantial proportion of pediatric hospitalizations and healthcare expenditures, with respiratory-related illness being one of the leading causes of admission. It is, therefore, important for the practitioner caring for these children to have knowledge of the common respiratory concerns in this population as well as prevention and management strategies. This review will describe the most common respiratory concerns in CMC and will provide an overview of diagnosis and management.

Abstract
Purpose To evaluate the impact of the COVID-19 pandemic on non-invasive positive airway pressure (PAP) usage among children with sleep-disordered breathing (SDB). Methods PAP usage data in children with SDB aged 1 to 18 years old at The Hospital for Sick Children, Canada, were analyzed. The PAP usage data were recorded for 3 months prior to and 3 months following the COVID-19 lockdown in Ontario, Canada. The primary outcomes of interest were (i) percentage of days that PAP was used for ≥ 4 h and (ii) average daily usage of PAP based on days when PAP was used. Results A total of 151 children were included. The mean (± SD) age and BMI were 12.6 ± 4.1 years and 28.7 ± 12.4 kg/m2, respectively. The median (IQR) percentage of days of PAP usage for ≥ 4 h and average nightly PAP usage was significantly higher during compared with prior to the pandemic (76.7 [19.0–94.0] vs 62.0 [15.5–89.0]%, p = 0.02, and 406.0 [244.0–525.0] vs 367.0 [218.0–496.0] min, p = 0.006, respectively). Within this cohort, 95/151 (63%) children with SDB showed increased PAP usage and 56/151 (37%) either decreased the amount of time they used PAP or stopped PAP use altogether. Conclusions COVID-19 pandemic has provided opportunities for increased PAP usage in a significant number of children with SDB. A subset of children with prior evidence for suboptimal PAP usage showed further decreases in PAP usage during the pandemic. This information is critical for clinicians to provide anticipatory guidance to encourage PAP usage both during the pandemic and beyond.

Abstract
Objectives To determine whether a change in clinical management (e.g., new tracheostomy or adenotonsillectomy) occurred following a polysomnogram (PSG) in children with medical complexity (CMC) and to explore whether families' goals of care (regarding results and treatment implications) were discussed prior to the completion of a PSG. Methods All CMC enrolled in a complex care program at the Hospital for Sick Children, Canada, who underwent a baseline PSG from 2009 to 2015 were identified. Exclusion criteria included (1) PSGs for ventilation titration and (2) PSGs outside the study time frame. Health records were retrospectively reviewed to determine demographics, medical histories, families' wishes, PSG results, and their impact on clinical care. Descriptive statistics were used to summarize results. Results Of 145 patients identified, 96 patients met inclusion criteria. Fifty (52%) were male. Median age was 3 years. Forty-eight (50%) were diagnosed with clinically significant (i.e., moderate to severe obstructive sleep apnea, central sleep apnea, and/or hypoventilation) sleep-related breathing disorders. Of those diagnosed, 9 (19%) had surgery, 25 (52%) underwent respiratory technology initiation, and 3 (6%) underwent both. In the remaining 11 (23%) patients, treatment was either considered too risky or did not align with the families' wishes. Only 3 of 96 patients had clear documentation of their families' wishes prior to PSG completion. Conclusion Recognizing the burden of medical tests for both the child and the health care system, a process of shared-decision making that includes clarifying a family's wishes may be prudent prior to conducting a PSG.

Abstract
The need for long-term noninvasive positive pressure ventilation (NiPPV) in children with chronic respiratory failure is rapidly growing. This article reviews pediatric-specific considerations of NiPPV therapy. Indications for NiPPV therapy can be categorized by the cause of the respiratory failure: (1) upper airway obstruction, (2) musculoskeletal and/or neuromuscular disease, (3) lower respiratory tract diseases, and (4) control of breathing abnormalities. The role of NiPPV therapy in select rare conditions (spinal muscular atrophy, congenital central hypoventilation syndrome, cerebral palsy, scoliosis, and Chiari malformations) is also reviewed.

Abstract
Sleep disorders in children with neurodevelopmental disorders are complex and reflect underlying genetic/biological and behavioural components. The sleep disorders are the same as in the typically developing child, although there may be some modifications to the presentation or the frequency depending on the phenotype. Consideration of the known phenotypes and environmental issues are important in defining management strategies. Despite this complexity, defined behavioural strategies with good sleep hygiene can have a significant effect on the sleep problem and on parental management of the behaviours.
