[Spinal-epidural anesthesia: hemodynamics and hemostasis]

Combined spinal epidural anesthesia using an original Portex kit was carried out in 62 patients operated on for orthopaedic, urological, and gynecological disorders. Hemodynamics was examined by tetrapolar chest rheography, hemostasis by electrocoagulography. Satisfactory blocking was attained in 98% cases, in 1 patient an accidental puncture of the subarachnoidal space with Tuohy needle occurred. Development of spinal block was associated with a reduction of heart productivity and hypocoagulation changes in the hemostasis. The parameters examined remained within the normal range of values.
