[Efficacy of oncologic surgery. Does anesthesia influence the postoperative outcome?]

Major surgical interventions in tumour surgery are still associated with perioperative cardiopulmonary, infectious, thromboembolic, cerebral, and gastrointestinal complications. There are different prophylactic and therapeutic possibilities to anticipate or counteract these perioperative complications. The most important, including beta blockers and alpha-2-agonists for patients at coronary risk, preoperative optimisation of oxygen transport in high risk surgical patients and the concept of multimodal perioperative therapy (analgesia, early mobilisation, early enteral nutrition, and others) combined with high perioperative inspiratory oxygen concentration and maintenance of normothermia to reduce wound infection and cardiac complications are described in this paper.
