All patients who require general anaesthesia are thoroughly examined. The pre-anaesthetic examinations include blood and urine tests which provide additional informations which can help us to tailor the anaesthesia protocol to the patient and reduce the risks to the minimum. Apart from the thorough planning we emphasize the importance of the monitoring during and after the procedure: we have dedicated staff who monitors our patients during anaesthesia and whose exclusive role is to measure and monitor the patients’ clinical parameters. Our modern anaesthesia monitors provide great help with this task. In order to achieve even higher safety standards of the general anaesthesia all of our patients receive an i.v. catheter through which we provide i.v. fluid therapy and after placing an endotracheal tube we maintain the anaesthesia with oxygen and gas anaesthetic.
