Throughout its history, anesthesia and critical care medicine has experienced vast improvements to increase patient safety. Consequently, anesthesia has never been performed on such a high level as it is being performed today. ⋯ It turned out that there is a complex variety of possible errors that can only be tackled through consistent implementation of a safety culture. The key elements to reduce complications are continuing staff education, algorithms and standard operating procedures (SOP), working according to the principles of crisis resource management (CRM) and last but not least the continuous work-up of mistakes identified by critical incident reporting systems.

Locally advanced carcinomas of the oesophagus require multimodal treatment. The core element of curative therapy is transthoracic en bloc oesophagectomy, which is the standard procedure carried out in most specialized centres. Reconstruction of intestinal continuity is usually achieved with a gastric sleeve, which is anastomosed either intrathoracically or cervically to the remaining oesophagus. ⋯ Oesophagectomies should only be performed in high-volume centres with the close cooperation of surgeons and anaesthesia/intensive care specialists. Programmes of enhanced recovery after surgery (ERAS) hold further potential for the patient's quicker postoperative recovery. In this review article the fundamental aspects of the interdisciplinary perioperative management of transthoracic oesophagectomy are described.

Inhalation as well as total intravenous anesthesia have both advantages and disadvantages. The pros of an inhalation technique are mask induction without the initial need for intravenous access and precise dosing; the pros of an intravenous technique are postoperative quiet recovery and a low incidence of vomiting. With both techniques the aim is to reach a certain, most often constant effect site concentration, which after a short latent period equals the blood concentration. ⋯ Dosing of intravenous anesthetics is based on assumptions. For neonates and young infants an inhalation technique is often preferred because of metabolic immaturity and the resulting difficulties of dosing, whereas older children can often profit from a quiet awakening and a reduced incidence of vomiting. The increased availability of syringe pumps with incorporated algorithms as well as of electroencephalograph (EEG)-based monitoring systems will further promote the popularity of total intravenous anesthesia.

Perioperative hypothermia is defined as a core temperature below 36 °C. The literature shows that perioperative hypothermia is a frequent but potentially preventable complication of the surgical process. The risk of experiencing perioperative hypothermia is inherent for all anesthetized patients, independent of the type of surgery. Unless preventative measures are taken, perioperative hypothermia occurs in 50 to 70 % of all surgical patients. In Germany and Austria the guideline "Preventing inadvertent perioperative hypothermia" has been published. In Wolfsburg we started already in 2012 with a standard operating procedure to prevent perioperative hypothermia in all surgical patients. In two clinical departments we established an additional prewarming-protocol starting prior to induction of anaesthesia on the normal ward on the day of surgery. ⋯ We conclude that temperature management is a challenge in the clinical situation, and that it is difficult to achieve rates of hypothermia close to zero. The addition of prewarming was very effective in improving the results in our patients.
