Postoperative respiratory complications of adenotonsillectomy for obstructive sleep apnea syndrome in older children: prevalence, risk factors, and impact on clinical outcome.

Objective: To determine the prevalence and type of respiratory complications after adenotonsillectomy for obstructive sleep apnea syndrome (OSAS) in otherwise healthy children with a completed preoperative polysomnography evaluation.

Design: Retrospective analysis.

Setting: Affiliated Hospital of Medical University, Guangzhou, Guangdong, China.

[Prevalence and prognostic factors for postoperative complications of uvulopalatopharyngoplasty in patients with obstructive sleep apnea hypopnea syndrome].

Objective: To explore the complication incidence and risk factors within immediate 24 hours after uvulopalatopharyngoplasty in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and provide theoretical foundation for preventing postoperative complication incidence.

Method: 162 patients undergoing UPPP procedure between Mar, 2002, and Oct 2006, were analysed retrospectively. All patients were divided into two groups according to the development of postoperative complications or not.

Association of body position with sleep architecture and respiratory disturbances in children with obstructive sleep apnea.

Conclusions: Sleep position in children with obstructive sleep apnea (OSA) did not affect the sleep architecture. Supine position had a significant influence on respiratory parameters and gas exchange. Lateral position did not affect respiratory parameters in children aged 3-5 years and little affected gas exchange except right lateral decubitus (RLD) position in children aged 11-13 years.

[Impact of adenotonsillectomy on quality of life in children with sleep disordered breathing].

Objective: To compare improvement in quality of life after adenotonsillectomy in children with similar demographics but with either obstructive sleep apnea hypopnea syndrome (OSAHS) or with milder forms of sleep-disordered breathing (SDB). To evaluate the relationship between polysomnogram (PSG) results and disease-specific quality of life for children with obstructive sleep apnea 18 item survey (OSA-18).

Method: Children with SDB who were suspected of having OSAHS were enrolled.

Comparison of polygraphic parameters in children with adenotonsillar hypertrophy with vs without obstructive sleep apnea.

Objective: To compare the polygraphic parameters in children with adenotonsillar hypertrophy (ATH) with vs without obstructive sleep apnea (OSA).

Design: Prospective controlled study.

Setting: Hospital-based pediatric otolaryngology practice.

[Sleep architecture changes in children with adenoidal hypertrophy].

Objective: Adenoidal hypertrophy in children is associated with obstructive manifestations like mouth breathing, snoring, night cough. However, the sleep architecture is poorly defined in children with AH, which is this studies for.

Method: A computer-assistant diagnostic system was used for polysomnography (PSG) recording.

Sleep architecture in children with adenoidal hypertrophy.

Aim: Adenoidal hypertrophy (AH) in children is associated with obstructive manifestations like mouth breathing, snoring. Unfortunately, little is known regarding sleep architecture of AH in children. The purpose of this study was therefore undertaken to investigate the polysomnographic variables in children with AH.
