In Germany it is common practice to use pulse oximetry and supplementary oxygen only on request in patients breathing spontaneously transferred to the post-anaesthesia care unit (PACU) following surgery under general anaesthesia. The main aim was to study the influence of medical training and clinical experience on assessing SpO(2) and detecting hypoxaemia(More)
BACKGROUND Studies conducted shortly after the implementation of pulse oximetry (PO) into clinical practice 20-25 years ago revealed that many patients breathing room air during transfer from the operating room (OR) to the post-anesthesia care unit (PACU) directly after general anesthesia (GA) had a peripheral oxygen saturation (S(p)O(2)) below 90%.(More)
BACKGROUND Due to a variety of reasons (e.g. increase in outpatient surgery and legal restrictions related to working hours) it has become increasingly more difficult to have the pre-anesthesia visit and the anesthesia carried out by the same anesthetist. In the light of these organizational changes as well as increasing economical pressure it has become(More)
BACKGROUND Obesity is a well-established risk factor for perioperative pulmonary complications. Anaesthetic drugs and the effect of obesity on respiratory mechanics are responsible for these pathophysiological changes, but tracheal intubation with muscle relaxation may also contribute. This study evaluates the influence of airway management, i.e. intubation(More)
OBJECTIVE Left lateral table tilt of 15° to 30° is recommended for cesarean section, although little is known about the practical problems of its implementation. This study examines these issues from the perspective of anesthesiologists, obstetricians, theater nurses, and patients. Initially, the tilt was set by visual estimation in 100 women and checked by(More)
OBJECTIVES To evaluate if subcutaneous continuous glucose monitoring (sCGM) is feasible in cardiac surgery and if reliable glucose values are reported under hypothermic extracorporeal circulation. DESIGN Feasibility trial. SETTING University hospital. PARTICIPANTS Ten consecutive patients undergoing coronary artery bypass grafting. INTERVENTIONS(More)
BACKGROUND The German Societies of Anesthesiology and Intensive Care Medicine, Internal Medicine and Surgery have recently published for the first time joint recommendations for the evaluation of adult patients prior to elective non-cardiac surgery. In these recommendations indications for preoperative diagnostic procedures were critically revised and(More)
Up to the present day, pain management in the ICU (Intensive Care Units) is a unresolved clinical problem due to patient heterogeneity with complex variation in etiopathology and treatment of the underlying diseases. Therefore, therapeutic strategies in terms of standard operating procedure (SOP) are a necessary to improve the pain management for intensive(More)
BACKGROUND Many anesthesia departments operate a pre-anesthesia assessment clinic (PAAC). Data regarding organization, equipment and structure of such clinics are not yet available. Information about modern anesthesiology techniques and procedures contributes to a reduction in emotional stress of the patients but such modern techniques often require(More)
The routine administration of supplemental oxygen to women undergoing elective caesarean section under regional anesthesia in order to optimize oxygen supply to the fetus is common anesthetic practice in many German hospitals. However, this practice has been controversially discussed in the non-German literature for many years. This review presents and(More)
