METHOD FOR DETERMINATION OF INDICATIONS FOR NASAL OBSTRUCTION RELEASE IN PATIENTS WITH OBSTRUCTIVE SLEEP APNEA SYNDROME Russian patent published in 2010 - IPC A61B5/08 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, predominately to otorhinolaryngology. For determination of indications for nasal obstruction release in patients with obstructive sleep apnea syndrome, basic anterior active rhinomanometry (AARM) is carried out. At night, respiratory monitoring and pulsoxymetry are carried out for determination of basic apnea/hypopnea incident (AHI) number per hour, sleep oxygen saturation less than 90 % incident (OSI) number per hour (ODI). The AARM with pharmacological test follows the next day after the administration of a long-acting intranasal vasoconstrictor. Thirty minutes before sleeping, the intranasal vasoconstrictor is introduced once more. By night, respiratory monitoring is used to determine the AHI and OSI with pharmacological test. When observing the AHI and OSI with pharmacological test decreased as compared with the basic values more than by three or one of the indicators decreased more than by three and the second indicator changed by three and less, nasal obstruction release for treating obstructive sleep apnea syndrome is indicated. If the AHI and OSI values are changed by three and less, nasal obstruction release is not indicated. If one or both AHI and OSI values are increased more than by three units, nasal obstruction release is contraindicated.

EFFECT: method improves accuracy of determination of indications for nasal obstruction release in patients with obstructive sleep apnea syndrome.
