[Hemodynamics and gas exchange during spine operations in the prone position]
Abstract:
Hemodynamics and respiratory metabolism of 30 patients in the prone position spine surgery under GA have been studied and analyzed. Results showed that there were no evident hemodynamic changes in patients without any risk of developing cardiovascular complications (ASA I-II). Posture effect of the circulation during anesthesia and spine operation was not marked. Data from our trials did not reveal any deterioration in gas exchange and acid-base balance in patients undergoing surgery in this position (ASA I-II) during adequate artificial respiration lasting 2 hours.
