[Can preoperative lung function diagnosis detect risk of intraoperative pulmonary gas exchange insufficiency in artificial hip replacement with polymethylmethacrylate cement?].
In a study of 90 patients in whom a hipjoint had been replaced for the first time using polymethylmetacrylate cement, the extent of intraoperative pulmonary gas exchange disorders was established. The effect of a preexisting disorder of lung function was determined. We checked whether an appraisal of the risk patients who are operated on can be assisted by a preoperative analysis of lung function. After preoperative diagnosis of lung function, the arterial blood gases were analysed at defined times during the operation. An intraoperative fall in the partial pressure of oxygen and an increase in carbon dioxide partial pressure in the arterial blood were found in all patients. There were pronounced interindividual differences in the extent of the disorder of pulmonary gas exchange. The degree of severity of the respective acute disorder of lung function did not show any correlation with the pre-existing disorder of pulmonary ventilation. Major hemodynamic changes were not observed. According to the present findings, a definitive statement with regard to the degree of severity of intraoperatively occurring disorders of pulmonary function cannot be expected from a preoperative analysis of pulmonary function.
