Dysfunction of external respiration in patients with spinal tuberculosis
Annotatsiya
Aim of the study was to determine the peculiarities of respiratory system dysfunctions and their effect on spinal tuberculosis clinical course. We studied FER in 95 patients with spinal tuberculosis aged from 20 to 60 yr old to determine the peculiarities of dysfunctions. Gravity of pulmonary breathing capacity dysfunctions was identified by abatement degree of VCL and MPBC: I degree – decrease in 16-35%; II degree - decrease in 36-55%; III degree – decrease more than 55%; In 72 patients were revealed disturbances of FER indices. Of them, 19,5% patients had moderate embarrassment of ventilation, 45,8% -considerable, and 34,7% - full-blown. Thus, in 58 patients LVC was decreased in considerable and strong embarrassment of ventilation in 1,5-2 times as compared with normal one and only in 14 patients was followed moderate decline. Study results established direct relation of LVC index decline from the size of spinal deformation. Therefore, LVC sharp decline was followed in patients with the maximum size of kyphosis (102,0±4,0), considerable - in moderate size of kyphosis (118,0±3,0). Normal indices and LVC moderate decline were noted in patients with minimum size of kyphosis (154,0±5,0). In 47 patients restrictive type of embarrassment of ventilation was observed. Combined type occurred in 14 patients, obstructive - in 11. Should be noted that despite LVC considerable and sharp decrease in most of examined patients, MPBC was rather in a lesser degree: in 17 patients outsized MPBC indices were determined, in 32 their moderate decline was noted. Consequently, the presence of cerebrospinal dysfunctions depending on their depth and localization embarrass significantly the ventilation indices in patients with tuberculous spondylitis.
