Comparative evaluation of therapeutic efficacy of Thornton adjustable positioner with Karwetzky activator in the management of obstructive sleep apnea syndrome

[Year:2011] [Month:January-March] [Volume:6] [Number:1] [Pages:6] [Pages No:14 - 19]

Keywords: Obstructive sleep apnea, Thornton adjustable positioner, Karwetzky activator

Abstract

Background: Mandibular advancement devices (MAD) are recognized as an effective option in the management of obstructive sleep apnea (OSA). Thornton adjustable positioner (TAP) allows gradual forward titration of mandible to optimize treatment outcome. Karwetzky activator is a fixed MAD and titration is not possible. Therefore a study was under taken to compare the therapeutic efficacy of TAP with Karwetzky activator in the management of OSA. Methods: Twenty polysomnography diagnosed OSA patients were prescribed TAP (Group I) and another twenty were prescribed Karwetzky activator (Group II). The therapeutic efficacy was evaluated on Apnea-Hypopnea Index (AHI) and Epworth Sleepiness Scale (ESS). Results: The percentage improvement in AHI scores in Group I was 52.48% compared to 42.37% in Group II. Statistically significant improvement (P<.001) in AHI and ESS scores was observed in Group I and Group II.75% and 55% positive responders (AHI improvement of >50) in Group I and Group II respectively were observed. Conclusion: Therapeutic efficacy and clinical acceptance of TAP was superior to Karwetzky activator. Superior performance of TAP can be attributed to gradual titration and optimum mandibular positioning.

Cardiac autonomic activity in young adults with short sleep

[Year:2011] [Month:January-March] [Volume:6] [Number:1] [Pages:4] [Pages No:20 - 23]

Keywords: sleep, heart rate variability (HRV), cardiac autonomic activity, low frequency power (LF), high frequency power (HF)

Abstract

Sleep deficit has been associated with autonomic imbalance. This study aimed to evaluate the effect of sleep duration on cardiac autonomic activity as determined by heart rate variability (HRV) in young adults. Method: Heart rate and frequency domain measures of HRV were evaluated from short-term electrocardiographic recordings (5 min each) of 95 medical students (37 women) in the age group of 18 to 22 years. Self reported duration of sleep during the previous month were noted. The data was analysed by grouping and comparing the subjects according to average sleep duration per day with >7hours (n=51) and <7 hours (n=44) as adequate and inadequate sleep respectively. Results: No difference was found in HRV indices and in heart rate between the sleep groups. The subjects with inadequate sleep had lower HF, HF in normalized units and higher values of LF, LF/HF ratio compared to adequate sleep group. Conclusion: Sleep deprivation over a month period do not alter cardiac autonomic activity in young adults as assessed by short-term heart rate variability.
