title: [Diagnostic and therapeutic importance of right-heart catheterization during operations on the lungs and in the early postoperative period in elderly patients].
abstract: Pressure in the right heart (CVP) was measured at different stages of lung resection and during the first postoperative days in 74 aged patients, operated upon for various pulmonary affections. Pneumonectomy was performed in 33 patients, partial resection--in 31, thoracotomy--in 10. The pressure was measured by catheterization of the right heart, using the Valdman apparatus. No complications relative to catheterization of the right heart were noted. Intraoperative observations over CVP dynamics with due account of other hemodynamic indices, general patient's state and the operative stage provide for additional valuable data of the state of a patient operated upon. During the first days after pneumo- and lobectomy CVP was found to be decreased compared with initial values, that seems to be related with hypovolemia. Studies on the circulating blood volume and its components, carried out in 18 patients, have proved the presence of hypolvolemia in patients under consideration. These investigations make it possible to recommend continous catheterization of the right heart for early recognition of hemodynamic disturbances and a simultaneous use of the catheter for infusion of medical drugs.
