Primary Outcome Measures:
  • Apnea-hypopnea index (AHI) [ Time Frame: ''Baseline PSG night'' and ''pure prone positioning night within two weeks of baseline PSG night'' ]
    Reduction in AHI during pure positioning night as compared to baseline night


Secondary Outcome Measures:
  • Nocturnal oxygen saturation [ Time Frame: ''Baseline PSG night'' and ''pure prone positioning night within two weeks of baseline PSG night'' ]
    Comparison of mean oxygen saturation, minimum oxygen saturation and proportion of time spent during sleep with oxygen saturation below 90% (as measures of nocturnal hypoxemia) in pure prone positioning night with that of the baseline night.

  • Sleep efficiency [ Time Frame: ''Baseline PSG night'' and ''pure prone positioning night within two weeks of baseline PSG night'' ]
    Improvement in sleep efficiency in prone positioning night as compared to baseline night.


Enrollment: 29
Study Start Date: March 2011
Study Completion Date: May 2011
Primary Completion Date: May 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Pure Prone Positioning
Sleeping in prone position by pure prone positioning device, which consisted of a pillow mounted on a table designed to keep the subjects sleeping prone.
Device: Pure prone positioning
Pure prone positioning device consisted of a pillow mounted on a table designed to keep the subjects sleeping prone.
Other Name: Positional treatment
No Intervention: Baseline
No intervention for sleep position

Detailed Description:
Sleeping in prone position could be effective in the management of obstructive sleep apnea (OSA) by reducing the gravity effect on the upper airway and hence collapsibility. Pure prone positioning (PPP) consisted of a pillow mounted on a table designed to keep the subjects sleeping prone with the head extended in line with the body.

Criteria

Inclusion Criteria:

  • Patients were enrolled to the study among one hundred and eighty-four consecutive patients who were admitted to our sleep center with 6 beds in a tertiary care hospital, during 3 months period. Of these, 36 patients with mild to moderate OSA (AHI=5-30 events/h) were invited to participate in the study based on the selection criteria, and 29 patients with mild to moderate OSA on their baseline PSG, (17 males, 12 females) gave informed consent and participated in the study.

Exclusion Criteria:

  • Patients having BMI>35 and/or abdominal and/or trunkal obesity that may hinder prone sleeping , upper airway pathology (nasal polyp, nasal turbinate hypertrophy, chronic sinusitis, nasal septum deviation, upper airway infection, Mallampati score and tonsil size grade of IV), any other concomitant sleep disorder (narcolepsy, periodic leg movement syndrome, insomnia, sleep related hypoventilation-hypoxemia and central sleep apnea syndrome), psychiatric disorder such as panic disorder, heart failure and coronary artery disease were not included in the study.
