METHOD FOR TRANSFERRING PATIENTS HAVING VERTEBRAL COLUMN LESION AT CERVICAL LEVEL TO SPONTANEOUS RESPIRATION MODE Russian patent published in 2006 - IPC A61M16/00 

FIELD: medicine.

SUBSTANCE: method involves following hemodynamic and peripheral saturation state, respiration rate and acid-base balance values, after having stabilized general patient condition and repaired consciousness. Neurological status is additionally estimated by recording somatosensory evoked potentials with N_11-13 and N_13-18 intervals. The N_11-13 and N_13-18 intervals remaining at the preoperative level or becoming shorter, respiratory support reduction starts and the patient is transferred to spontaneous respiration mode. The N_11-13 and N_13-18 intervals growth being found to be 0.2 ms as large relative to preoperative period or their instability being observed for 30-60 min, transfer to spontaneous respiration mode is to be stopped. After having transferred a patient to spontaneous respiration mode in the cases of N_11-13 and N_13-18 intervals reduction below the preoperative period level, somatosensory evoked potential control lasts for 2 h. The intervals remaining unchanged at the preoperative period level or their oscillation being within ±0.1 ms, somatosensory evoked potential control lasts for 6 h. The hemodynamic and peripheral saturation state, respiration rate and acid-base balance values monitoring procedure is continued during 12 h after having separated a patient from respirator.

EFFECT: enhanced effectiveness in determining optimum moment for reducing respiration support.
