Antibiotic stewardship (ABS) comprises a bundle of different interventions to improve anti-infective treatment in a hospital setting. An important component of ABS interventions is the interdisciplinary approach to infection management. Besides improving infrastructural aspects on a hospital level, including surveillance of the use of anti-infective agents and nosocomial infections, collation and interpretation of statistics on resistance and formulation of local treatment guidelines, ABS teams go to the wards and advise treating physicians on antibiotic therapy. ⋯ An important overall objective of ABS is the reduction of resistance induction in order to preserve the therapeutic efficiency of antibiotics. A number of studies have shown that this goal can be achieved in different clinical settings without negatively affecting patient outcome. The strategies of ABS can also be applied with no problems to critically ill patients on the intensive care unit.

Inadvertent perioperative hypothermia, which is defined as a core body temperature of less than 36.0 °C, can have serious consequences in surgery patients. These include cardiac complications, increased blood loss, wound infections and postoperative shivering; therefore, the scientific evidence that inadvertent perioperative hypothermia should be avoided is undisputed and several national guidelines have been published summarizing the scientific evidence and recommending specific procedures. The German AWMF guidelines were the first to emphasize the importance of prewarming for surgery patients to avoid inadvertant perioperative hypothermia; however, in contrast to intraoperative warming, prewarming is so far not sufficiently implemented in clinical practice in many hospitals. Furthermore, a recent study has questioned the effectiveness of prewarming. ⋯ Prewarming, as recommended in the AWMF guidelines, resulted in a significant and clinically relevant reduction in the incidence of inadvertent perioperative hypothermia; therefore, prewarming can still be regarded as an effective method to avoid perioperative hypothermia. Hypothermia rates of 15.8% intraoperatively and 5.1% postoperatively can be achieved in clinical practice, when prewarming is performed in addition to intraoperative warming in the anesthesia induction room directly before the start of surgical procedures.

Critical incidents in difficult airway management are still a main contributory factor for perioperative morbidity and mortality. Many national associations have developed algorithms for management of these time critical events. For implementation of these algorithms the provision of technical requirements and procedure-related training are essential. Severe airway incidents are rare events and clinical experience of the individual operators is limited; therefore, simulation is an adequate instrument for training and evaluating difficult airway algorithms. ⋯ The conformity to the algorithm of over 90% indicates a good training level of the participants concerning the difficult airway algorithm. In the observed sample flexible intubation endoscopy tended to be of high significance even in the unanticipated difficult airway. Cricothyrotomy was performed faster surgically than by the use of the transtracheal puncture approach, while no differences between junior and senior anesthetists were observed. For the successful management of an unexpected difficult airway, specific training of these special and rare events is crucial. A standardized provision of special airway instruments stored in a special trolley and frequent application of this trolley in the clinical routine is recommended.

In response to the global increase in antibiotic resistance, the concept of antibiotic stewardship (ABS) has become increasingly important in recent years. Several publications have demonstrated the effectiveness of ABS, mainly in university facilities. This retrospective observational study describes the implementation of ABS in a basic care hospital. ⋯ The preinterventional/postinterventional comparison showed a significant reduction in the overall consumption of antibiotics with a redistribution in favor of antibiotics with a lower resistance selection. At the same time, the resistance rate of E. coli decreased. The increase of the blood culture rate indicates the optimization of diagnostic procedures. This ABS program had to be established with reduced resources but this seems to have been compensated by the more personal contact addressing the care takers and short chain of commands, as is possible in smaller hospitals. Presumably, the structure of basic care hospitals is particularly suitable for concepts covering entire hospitals. Further clusters of randomized studies are necessary to confirm this.
