Abstract:
Objective:To determine the objective effects of adenotonsillectomy on pediatric obstructive sleep apnea hypopnea syndrome (OSAHS) through analyzing the polysomnography (PSG) results between pre and post-operation.
Methods:A total of 56 pediatric OSAHS patients were included who underwent adenoidectomy or/and tonsillectomy and completed PSG follow-up from January 1, 2017 to March 31, 2018. All the pediatric patients who underwent adenoidectomy or/and tonsillectomy during the research period were arranged to take a preoperative PSG study. Patients who were diagnosed OSAHS would be encouraged to complete a follow-up PSG study ranged from1 to 3 months after surgery. The parameters of respiration and sleep architecture of PSG were compared and analyzed. The paired student t test was used to compare preoperative and postoperative mean values. The unpaired student t test was used to compare quantitative variables among different groups. The rank sum test was used if the data were abnormal distribution.
Results:Totally 238 patients completed preoperative PSG study, 62 patients were diagnosed as pediatric OSAHS, 56 eligible patients finished post-operative PSG. Hypopnea was the majority in all type of respiratory events in 56.45% (35/62) subjects, while central apnea as the majority in 29.03% (18/62) subjects who can also get significant CAI decrease after surgery. However, obstructive apnea as the majority only exist in 14.52% (9/62) subjects. The short-term cure rate of pediatric OSAHS was 85.71% (48/56). The postoperative AHI, MAI, CAI, HI, ODI, LoSpO2, percentage of stage I sleep and arousal index were significantly decreased, however, the OAI was no statistical decrease. The percentage of stage Ⅱ and rapid eye movement (REM) sleep were significantly increased, while no significant change in percentage of slow wave sleep and sleep efficiency(t=2.32, P=0.017).
Conclusions:Pediatric OSAHS manifest different characteristics of respiratory events from that of adults. Adenotonsillectomy can significant decrease respiratory events and improve sleep architecture, however, there are still some patients who can′t be completely relieved with adenotonsillectomy.
