[Effect of pulmonary ventilation capacity on the postoperative course in thoraco-pulmonary surgery]

The authors made a statistical investigation of the postoperative evolution in thoraco-pulmonary surgery and found diffuse hemorrhage, alterations in the evolution of wound healing, failures, higher death-rate and longer hospitalization, higher incidences being noted, inverse relationship with the pulmonary ventilation. These phenomena are attributed to the respiration disturbances, without patient clinical manifestations. The utility of the global spyrogram is acknowledged, when there are no other dysfunctions. The authors consider as lower limits of the spyrographic data, under which the surgical indications are fraught with too high a risk, values between 50 and 60% of the theoretical ones.
