Effect of Sleep Apnea on Blood Pressure Control and Outcome Early After Subarachnoid Hemorrhage

Effect of Sleep Apnea on Blood Pressure Control and Outcome Early After Subarachnoid Hemorrhage

In this observational study patients with subarachnoid hemorrhage (SAH) will be screened for sleep apnea (SA) to investigate if SA is associated with impaired blood pressure control and worse clinical outcome early after SAH.

Patients admitted with non-traumatic SAH will be consented and screened for sleep apnea within 48 hours after hospital admission. Blood pressure and clinical outcome will be monitored throughout ICU treatment and hospital stay, respectively. Diagnosis of sleep apnea will be confirmed on follow-up 3-6 month after SAH by sleep apnea screening (portable cardiorespiratory monitoring and out-of-center polysomnography, respectively).

Inclusion Criteria:

• Subarachnoid Hemorrhage (Hunt & Hess 1 to 4)
• > 18 years of age
• Ability to consent for study of healthcare proxy able to confirm patient will to participate

Exclusion Criteria:

• Stoke within 3 month prior to admission
• Intubation prior or within 24 hours after admission
• no healthcare proxy
