Efficacy of oncologic surgery. Does anesthesia influence postoperative outcome?

Major surgical interventions in tumour surgery are still associated with pe rioperative cardiopulmonary, infectious, thromboembolic, cerebral, and gast rointestinal complications. There are different prophylactic and therapeuti c possibilities to anticipate or counteract these perioperative complicatio ns. The most important, including beta blockers and alpha-2-agonists for pa tients at coronary risk, preoperative optimisation of oxygen transport in h igh risk surgical patients and the concept of multimodal perioperative ther apy (analgesia. early mobilisation, early enteral nutrition, and others) co mbined with high perioperative inspiratory oxygen concentration and mainten ance of normothermia to reduce wound infection and cardiac complications ar e described in this paper.
