    Journal: Prakt Anaesth; 1979 Feb; 14(1):41-7. PubMed ID: 419060.
    Abstract:
    The haemodynamics of the pulmonary and systemic circulation during anaesthesia and surgical treatment of a hip fracture were investigated in 26 patients (mean age 73 +/- 4.5 years). After induction of spinal anaesthesia the mean arterial pressure, right atrial pressure, pulmonary capillary wedge pressure and systemic vascular resistance were significantly reduced. The cardiac index remained constant due to mild tachycardia. During the operation no significant variations of the haemodynamic parameters were observed. Implantation of methylmethacrylate in 10 patients was followed by a significant increase of the mean pulmonary pressure and pulmonary vascular resistance. The PaO2 DECREASED. 15 minutes after implantation the original values were again reached.
