UnlabelledIn this prospective study the preoperative risk classification and pulmonary status was compared to postoperative mortality and morbidity, following either spinal or general anaesthesia. We studied 408 consecutive orthopaedic patients. Comparing the anaesthetic methods we found no differences in mortality or in frequency of cardiac complications, while the non-cardiac complications were seen more frequently in patients who had undergone spinal anaesthesia (p < 0.05). Patients from the lower risk groups with a preoperative abnormal pulmonary status had a higher frequency of postoperative pulmonary complications following spinal anaesthesia than following general anaesthesia (p = 0.015).In Conclusion1) We find no difference in postoperative mortality depending on the anaesthetic method chosen, 2) the predictive value of the Boston Cardiac Risk index is identical for the two anaesthetic methods, and 3) the anaesthetic method of choice for the pulmonary disabled patient has not yet been established.
