OBJECTIVE To compare secondary postoperative haemorrhage rate of coblation with the conventional pediatric adenotonsillectomy. And to analyze possible reasons which cause the secondary bleeding after coblation adenotonsillectomy. METHODS A retrospective study was applied to compare the secondary postoperative haemorrhage rate and the bleeding moment(More)
OBJECTIVE To explore the correlation between periodic limb movement index (PLMI) and the apnea-hypopnea index (AHI), apnea index (AI), hypopnea index (HI) and lowest oxygen saturation (LSaO₂) in sixty-four children with sleep-disordered breathing (SDB). METHODS Between March 2008 and May 2009, sixty-four children suspected of OSAHS underwent overnight(More)
OBJECTIVE To observe the symptoms of inattention, hyperactivity among obstructive sleep apnea hypopnea syndrome (OSAHS) children, also to investigate the effects of surgery (tonsillectomy and adenoidectomy or adenoidectomy alone) on the changes of sleep architecture and inattention-hyperactivity score (IHS). METHODS Between June 2004 and may 2007, eighty(More)
OBJECTIVE To explore the diagnostic value of pulse transit time (PTT) in children with sleep disordered breathing(SDB). METHODS Forty eight randomly selected snorers (2 - 13 years) with SDB were examined by PSG and PTT in the same time. Data obtained were analyzed by different technicians respectively. Statistics and analysis of the data were performed.(More)
OBJECTIVE To explore the difference of arousal index between the children with obstructive sleep apnea-hypopnea syndrome (OSAHS) and children with primary snoring. Furthermore, to explore the correlation between the above mentioned arousals and the apnea-hypopnea index (AHI) and lowest oxygen saturation (LSaO(2)). METHODS Between March 2007 and February(More)
OBJECTIVE To analyse the clinical features of children with obstructive sleep apnea-hypopnea syndrome (OSAHS), accompanying with risk factors. METHODS The clinic data of 19 patients treated in the Department of Otorhinolaryngology of Guangzhou Children's Hospital between January 2005 to January 2008 were investigated retrospectively.

METHODS From 2003 to 2009, all children with airway foreign body who received two or more operations in hospital were enrolled. The clinical manifestations, image before and after(More)
OBJECTIVE To explore the level of serum uric acid (UA) in children with obstructive sleep apnea/hypopnea syndrome (OSAHS). METHOD Between Sep. 2008 and Mar. 2010, 138 children with OSAHS were enrolled in study group. Sixty-five children with accessory auricle or ptosis of upper lid were enrolled into the control group. Furthermore, according to(More)
OBJECTIVE To analyze the similarities and differences of the clinical manifestations between the children with upper airway resistance syndrome (UARS) and obstructive sleep apnea-hypopnea syndrome (OSAHS), and to explore the clinical features and characteristics of sleep respiratory parameters. METHODS Using the double-blind method, all children were(More)
OBJECTIVE To analyze polysomnogram characteristics of children with suspected obstructive sleep apnea hypopnea syndrome (OSAHS) and to explore the role of obstructive apnea index (OAI), apnea hypopnea index (AHI) and arousal index for pediatric OSAHS diagnosis. METHODS Sixty one suspected pediatric OSAHS cases had overnight polysomnography for at least 8(More)
