Stroke and CPAP Outcome Study: A Sham-controlled Trial of CPAP Among Stroke Rehabilitation Patients

2015-09-17 03:38:22 | BioPortfolio

Summary

The purpose of this study is to assess the effect of continuous positive airway pressure (CPAP) on functional outcome in patients with acute stroke, the investigators conducted a sham-controlled, double-blind pilot trial during inpatient rehabilitation.

Patients with acute stroke were recruited and randomly assigned to auto-titrating or sham-CPAP during their rehabilitation stay.

Description

All acute stroke patients admitted to the inpatient rehabilitation service at the University of Washington were invited to participate in the study. Given the high prevalence of obstructive sleep apnea (OSA) in this population, no screen for OSA was performed. Enrolled patients were assigned randomly to active-CPAP with auto-titrating pressures or to sham-CPAP with an otherwise identical device but with pressures ≤ 1 cm water. Subjects used active or sham-CPAP for the duration of inpatient rehabilitation, but no longer than 28 days. CPAP compliance was assessed by memory card that recorded mask-on time. Other information on download, such as apnea-hypopnea index, was only available on active-CPAP and not assessed by investigators in real time. In this study, the investigators defined tolerance as any continued use of CPAP at night and adherence as mean hours of CPAP use per night in those who were CPAP tolerant.

Medical and Biotech [MESH] Definitions

Restoration of functions to the maximum degree possible in a person or persons suffering from a stroke.

Used as an indicator in titrating iron and for the colorimetric determination of chromium and the detection of cadmium, mercury, magnesium, aldehydes, and emetine.

Stroke caused by lacunar infarction or other small vessel diseases of the brain. It features hemiparesis (see PARESIS), hemisensory, or hemisensory motor loss.

A group of pathological conditions characterized by sudden, non-convulsive loss of neurological function due to BRAIN ISCHEMIA or INTRACRANIAL HEMORRHAGES. Stroke is classified by the type of tissue NECROSIS, such as the anatomic location, vasculature involved, etiology, age of the affected individual, and hemorrhagic vs. non-hemorrhagic nature. (From Adams et al., Principles of Neurology, 6th ed, pp777-810)

A condition caused by the failure of body to dissipate heat in an excessively hot environment or during PHYSICAL EXERTION in a hot environment. Contrast to HEAT EXHAUSTION, the body temperature in heat stroke patient is dangerously high with red, hot skin accompanied by DELUSIONS; CONVULSIONS; or COMA. It can be a life-threatening emergency and is most common in infants and the elderly.
