METHOD FOR CONTROLLING RESPIRATORY DISORDERS IN ADMINISTERING SEDATION TO PATIENTS WHEN GIVING EPIDURAL ANESTHESIA

摘要

FIELD: medicine.;SUBSTANCE: method involves applying sedation and setting laryngeal mask after having done epidural anesthesia. Next, controlled mechanical lung ventilation is carried out without total myorelaxation being applied in CMV mode selecting respiration volume being equal to 6-8 ml/kg of body weight, peak flow value of 50-65 l/min in applying rectangular gas mixture injection mode or 65-85 l/min in applying descending gas mixture injection mode. Inspiration-to-expiration ratio is selected 1:1.3-1:1.7, oxygen fraction FiO₂ in inhaling being equal to 0.25-0.3, forced breathes frequency equal to 10-16 per 1 min, basic positive pressure value at the expiration end being equal to 3-4 cm of water column. The operation being over, the laryngeal mask is removed and auxiliary non-invasive lung ventilation with air and oxygen mixture is applied via facial mask in breathing support mode with PSV pressure. The support pressure is equal to 10-15 cm of water column on inhaling, oxygen fraction FiO₂ in inhaling being equal to 0.25-0.3, positive pressure value at the expiration end being equal to 2-3 cm of water column, trigger sensitivity being 2-3 l/min. Respiration support is continued until respiration volume is not less than 6-7 ml/kg of body weight.;EFFECT: reduced risk of negative consequences; accelerated respiratory rehabilitation.
