[On the safe side? Safety culture and patient safety in German anesthesiology clinics-A nationwide survey on the status quo]. / Auf Nummer sicher? Sicherheitskultur und Patientensicherheit an deutschen anästhesiologischen Kliniken ­ Eine deutschlandweite Umfrage zum Status quo.

BACKGROUND: A good safety culture may be predominantly defined by an open and unsanctioned communication about critical and erroneous courses. In an effort to improve patient safety various instruments, such as the critical incident reporting system (CIRS) or in terms of patient handover, the use of the situation, background, assessment, recommendation (SBAR) system patient handover, have been developed and are recommended by the German Society of Anaesthesiology and Intensive Care Medicine (DGAI). This study aimed at identifying how anesthesiologists perceive the safety culture in their current department and whether CIRS or SBAR are already established or not. MATERIAL AND METHODS: All registered members of the DGAI and the Professional Association of German Anaesthesiologists (BDA, n = 19,042) were invited to participate in an online survey on patient safety. In this survey there was a focus on the perceived safety culture and the experience with CIRS and SBAR. RESULTS: Of the participants 76.6% (n = 1372) stated that their department of anesthesiology has a good safety culture, while in 23.4% (n = 419) there was not. For the whole hospital the safety culture was only rated as being positive by 54.3% (n = 949) of the respondents. An open communication about critical and erroneous courses occurred in 76.5% (n = 1375) according to the participants, 23.0% (n = 408) had the impression that in the case of errors the respective person was being denounced. In one third of the participants' departments (n = 630, 36.6%) there were no morbidity and mortality conferences. The acronym CIRS was familiar to 98.9% (n = 1801) of the participants, 84.8% (n = 1544) of the surveyed anesthesiologists reported that CIRS was established in their departments. Critical incidents have been reported via CIRS by 54.4% (n = 839) of the respondents. Only 29.4% (n = 462) of the participants received regular feedback on CIRS reports. The acronym SBAR as a handover tool is unknown to the majority of the surveyed participants (n = 1181, 63.7%) and 86.1% (n = 1554) consider using an instrument in order to improve handover quality as possibly being beneficial. CONCLUSION: Anesthesiologists rate the quality of the safety culture of their own anesthesiology department to be higher compared to their hospital in general. In some hospitals there is denouncement in cases of erroneous courses according to the respondents. In the patients' point of view morbidity and mortality conferences should be established more often. CIRS is known to almost every surveyed anesthetist but feedback on a regular basis is sparse. This contradicts the claims of the German Coalition for Patient Safety. The acronym SBAR is unknown to the majority of surveyed participants despite the recommendation of the DGAI to implement it. There is a wish for tools in order to enhance the quality of handovers.

Evaluation of digital thermal monitoring as a tool to assess perioperative vascular reactivity.

AIM: The inflammatory response following tissue injury after major surgery is known to affect endothelial function and vascular reactivity. In this study we evaluated the utility of bedside Digital Thermal Monitoring (DTM) as a surrogate for evaluating vascular function in the postoperative period. METHODS: Ischemia-induced reactive hyperemia variables were measured in sixty patients scheduled for major thoracic surgery using DTM (VENDYS 5000BC; Endothelix, Inc., Houston, TX, USA) at baseline and at 24, 48, 72 hours, and day 5 postoperatively. Furthermore, baseline DTM variables (TR, aTR and AUCTR) and postoperative kinetics of these variables were compared among patients with and without preoperative chemo-radiation and cardiovascular risk factors. RESULTS: There were no significant differences in the DTM parameters measured at baseline and on each of the studied postoperative days. Compared to the baseline, the lowest measures of all variables were observed 24 hrs postoperatively and the highest measures of all variables were observed at 72 hrs. Patients with abdominal obesity and smoking had lower DTM values than the rest of the study group. CONCLUSIONS: In our study, DTM as measured by the VENDYS 5000BC DTM system (Endothelix, Inc.) did not reveal significant changes in ischemia-induced reactive hyperemia (vascular reactivity) between the baseline and after surgery in the postoperative period. Patients with certain cardiovascular risk factors (abdominal obesity, smoking) had a significant lower DTM signal. Whether this novel non-invasive technique is able to serve as a perioperative diagnostic tool for patients in a clinical setting warrants further study.

The impact of Trendelenburg position and positive end-expiratory pressure on the internal jugular cross-sectional area.

BACKGROUND: Increasing the cross-sectional area (CSA) of the right internal jugular vein facilitates cannulation and decreases complications. Maneuvers such as the Trendelenburg tilt position and ventilation with a positive end-expiratory pressure (PEEP) may increase the CSA of the right internal jugular vein. We determined the changes in the CSA in response to different maneuvers. METHODS: The CSA (cm(2)) of the right internal jugular vein was assessed in 50 anesthetized adult cardiothoracic surgery patients using 2-dimensional ultrasound. First, the CSA was measured in response to supine position with no PEEP (control condition, S0) and compared with 5 different randomly ordered maneuvers: (1) PEEP ventilation with 5 cm H(2)O (S5), (2) PEEP with 10 cm H(2)O (S10), (3) a 20 degrees Trendelenburg tilt position with a PEEP of 0 cm H(2)O (T0), (4) a 20 degrees Trendelenburg tilt position combined with a PEEP of 5 cm H(2)O (T5), and (5) a 20 degrees Trendelenburg tilt position combined with a PEEP of 10 cm H(2)O (T10). RESULTS: All maneuvers increased the CSA of the right internal jugular vein with respect to the control condition S0 (all P < 0.05). S5 increased the CSA on average by 15.9%, S10 by 22.3%, T0 by 39.4%, T5 by 38.7%, and T10 by 49.7%. CONCLUSION: In a comparison of the effectiveness of applying different PEEP levels and/or the Trendelenburg tilt position on the CSA of the right internal jugular vein, the Trendelenburg tilt position was most effective.

[In-hospital resuscitation. Concept of first-responder resuscitation using semi-automated external defibrillators (AED)]. / Reanimation im Krankenhaus. Konzept einer "First-Responder"--Reanimation unter Einsatz semi-automatischer externer Defibrillatoren.

BACKGROUND AND OBJECTIVE: The prognosis after in-hospital resuscitation has not significantly improved in the last 40 years. This account presents the results over a three-year period of a hospital-wide emergency plan which implements the use of an automated external defibrillator (AED) by the first responder to the emergency call. BACKGROUND AND OBJECTIVE: 15 "defibrillator points" were installed, which could be reached within 30 s from all wards, out-patient departments and other areas, thus making them accessible for immediate defibrillator application. The hospital personnel is trained periodically in the alarm sequence, cardiopulmonary resuscitation and use of the defibrillator. Data on 57 patients who had sustained a cardiac arrest were prospectively recorded and analysed. RESULTS: In 46 patients (81%) the "on-the-spot" personnel (first-responder) was able to apply AED before arrival of the hospital's resuscitation team. Mean period between arrest alarm and activation of the AED was 2.2 (0.7-4.7) min. Ventricular fibrillation or ventricular tachyarrhythmia was recorded in 40 patients, making immediate shock delivery by AED possible. Restoration of the circulation was achieved in 23 (80%) of the patients and 20 (50%) were discharged home, 17 (43%) without neurological deficit. The high proportion of first-responder AED applications and evaluation of the personnel training indicate a wide acceptance of the emergency plan among the personnel. CONCLUSION: An immediate resuscitation plan consisting of an integrated programme of early defibrillation is feasible and seems to achieve an improved prognosis for patients who have sustained an in-hospital cardiac arrest.

[Traumatological reflection on the narrow spinal canal. Review and our own concept]. / Der enge Spinalkanal aus traumatologischer Sicht. Ubersicht und eigenes Konzept.

Even today, injuries of the spinal column still pose a large challenge for the treating trauma surgeons. In the last century due to more differentiated diagnostics, the concept of predominantly conservative treatment changed to interventional procedures especially in the so-called unstable injuries. Discrepancies still exist in the evaluation of stability. In the last few years, dorsal, ventral, or combined interventional procedures have become established. The narrow spinal canal and neurological deficits represent important factors. Based on the literature, the different procedures and evaluations are discussed and finally we introduce our own concept.

[A simple fixation of antigens suited for the demonstration of autologous antibodies (author's transl)]. / Einfache Fixierung von Antigensubstraten für den Autoantikörpernachweis.

To determine autoantibodies against nuclear constituents, parietal cells, smooth muscles, mitochondria, microsomes of the thyreoidea and against myocard we use 4 micrometer cryostat tissue sections or monolayer cell preparations. After stepwise desiccation they are shortly heated to 100 degrees C. Antigenicity and histological structures are fully preserved for months, if these substrates were stored at -20 degrees C, provided that rehydration by even traces of moisture is carefully prevented.
