Jan Mohd Bhat, Ishfaq Ahmad Bhat, Mir Yasser Abdullah

Background: Obstructive Sleep Apnea in children (OSA) is a sleep-disordered breathing (SDR) characterized by partial or complete obstruction of the upper airways (UA) during sleep and interfere with sleep patterns and growth and development in children. The present study was conducted to assess the role of efficacy of a Karwetzky activator in pediatric patients with OSA. Materials & Methods: The present study was conducted on 54 patients OSA patients of both genders. The Karwetzky activator was given in patients with obstructive sleep apnea (OSA). They were initially treated successfully with this appliance. Further polysomnographic registrations at 6 to 12 weeks (T1) after the start of treatment, 6 to 12 months (T2) and 18 to 24 months (T3) later were performed for each patient wearing the appliance. Results: Out of 54 patients, boys were 24 and girls were 30. The mean Apnea-hypopnea index at T0 was 17.4 events/hour, at T1 was 4.2 events/hour, at T2 was 8.1 events/hour and at T3 was 8.3 events/hour. Apnea index was 8.4, 1.4, 3.2 and 4.6 events/hour at T0, T1, T2 and T3 respectively. Mean oxygen saturation was 94.2, 93.1, 93.5 and 94.1% at T0, T1, T2 and T3 respectively. Minimal oxygen saturation (%) was 79.2, 83.4, 79.5 and 80.6 at T0, T1, T2 and T3 respectively. Oxygen desaturation index was 13.2, 5.4, 9.4 and 9.2 at T0, T1, T2 and T3 respectively. Rapid eye movement sleep (%) was 13.7, 14.2, 14.8 and 15.2 at T0, T1, T2 and T3 respectively. Sleep in supine position (%) was 42.3, 47.5, 39.4 and 45.2 at T0, T1, T2 and T3 respectively. The difference was significant (P< 0.05). Conclusion: Authors found that Karwetzky activator is useful in management of mild-to-moderate OSA.
