Quality comparison of remote anesthetic consultation versus on-site consultation in children with sedation for a magnetic resonance imaging examination-A randomized controlled trial.

BACKGROUND: In the course of the corona pandemic, digital media has increasingly been used in many areas of medical practice to reduce personal contact. As it is of interest whether this can be practiced in the context of anesthesia consultations without loss of quality, we interviewed parents whose children received a cardiac or neuro magnetic resonance imaging (MRI) under sedation. Parents either received an on-site or a remote consultation conducted by an anesthesiologist. Both parents and anesthesiologist were asked to indicate their satisfaction with the respective consultation procedure in a questionnaire. AIM: The aim of this study was to investigate if remote pre-anesthesia consultation, supported by an online video, for parents whose children are receiving MRI examinations under sedation can replace the commonly performed on-site consultation, without decreasing its quality. METHODS: In this randomized trial, a total of 200 patients were included, one half received pre-anesthesia consultation on-site and the other half was given a link to a video and pre-anesthesia consultation was conducted by phone. As a primary analysis, we compared the level of satisfaction for the general procedure, the quality of the pre-anesthesia consultation and the contact to the anesthesiologists (or parents). We further investigated the frequency of complications and the preference for a possible next informed consent. RESULTS: Both groups showed high levels of satisfaction. Some anesthesiologists and parents were less satisfied with the quality of on-site pre-anesthesia consultation than with the remote. In our patient cohort, there was no evidence for higher risk of complications when information was provided by telephone. Further, parents as well as anesthesiologists clearly favored the combined form of telephone information and online video. Overall, 61.2% of parents and 64% of anesthesiologists would choose this form of pre-anesthesia consultation for repeat anesthesia. CONCLUSIONS: We did not observe that combined telephone and video decreased the quality of pre-anesthesia consultation. A remote version seems feasible for simple procedures such as sedation for MRI. Further research on this topic in other areas of anesthesia would be beneficial.

Pediatric emergence delirium is linked to increased early postoperative negative behavior within two weeks after adenoidectomy: an observational study.

BACKGROUND: The aim of this prospective multicenter observational study was to measure the incidence of postoperative pediatric emergence delirium and to investigate the occurrence of early postoperative negative behavior within two weeks after outpatient adenoidectomy in preschool children. METHODS: The study comprised 222 patients (1-7 years of age). All children received a multimodal anesthesia based on total intravenous anesthesia with propofol and remifentanil in combination with piritramid (0.1 mg.kg-1), ibuprofen (10 mg.kg-1), dexamethason (0.15 mg.kg-1), and ketanest S (0.1 mg.kg-1). We evaluated emergence delirium using the Pediatric Anesthesia Emergence Delirium Scale (PAED) at different predefined time points during the recovery period. Emergence delirium was defined as a PAED score ≥ 9 for the first three criteria. Additionally, we defined early postoperative negative behavior to be present when at least 5 of 27 criteria of the post hospitalization behavior questionnaire were positive. RESULTS: The incidence of emergence delirium following our anesthetic regime was 23%. The incidence of early postoperative negative behavior was significantly higher among patients with emergence delirium (24% vs. 11%, p = 0.04). The two categories, "sleep disturbance" and "separation anxiety", tested within the questionnaire for early postoperative negative behavior, were identified as the most common postoperative negative behavioral changes. CONCLUSION: Emergence delirium not only plays a role immediately after surgery but is also linked to early postoperative negative behavior within two weeks after outpatient adenoidectomy. Parents should be informed that early postoperative negative behavior may occur in 1 out of 4 patients if emergence delirium was present postoperatively.

A National Survey: Current Clinical Practice in Pediatric Anesthesia for Congenital Heart Surgery.

BACKGROUND: Providing anesthesia for pediatric patients undergoing congenital cardiac surgery is complex and requires profound knowledge and clinical experience. Prospective studies on best anesthetic management are missing, partially due to different standards. The aim of the present study was to survey the current standard practice in anesthetic management in pediatric cardiac surgical centers in Germany. METHODS: All 78 cardiac surgical centers in Germany were reviewed for a congenital cardiac surgery program. Centers with an active program for congenital cardiac surgery were interviewed to participate in the present online questionnaire to assess their current anesthetic practice. RESULTS: Twenty-seven German centers running an active program for congenital heart surgery were identified, covering more than 3,000 pediatric cardiac surgeries annually. Of these centers, 96.3% (26/27) participated in our survey. Standard induction agents were etomidate in 26.9% (7/26), propofol in 19.2% (5/26), a combination of benzodiazepines and ketamine in 19.2% (5/26), and barbiturates in 11.5% (3/26). General anesthesia was preferentially maintained using volatile agents, 61.5% (16/26), with sevoflurane being the most common volatile agent within this group, 81.2% (13/16). Intraoperative first-choice/first-line inotropic drug was epinephrine, 53.8% (14/26), followed by milrinone, 23.1% (6/26), and dobutamine 15.4% (4/26). Fast-track programs performing on-table extubation depending on the type of surgical procedure were established at 61.5% (16/26) of the centers. CONCLUSION: This study highlights the diversity of clinical standards in pediatric cardiac anesthesia for congenital cardiac surgery in Germany.

[Drama in the Recovery Unit: Paediatric Emergence Delirium]. / Drama im Aufwachraum: pädiatrisches Emergence-Delir.

The upcoming and ongoing debate on neurotoxicity of anesthetics at a young age put a new spotlight on the emergence delirium of children (paedED). The European Society for Anesthesiology published a consensus guideline on prevention and therapy in 2017 which can be a useful guidance in daily clinical practice. Patient data management systems with their clear documentation concerning pain/therapy of pain and paedED will be valuable tools in order to assess the real incidence of paedED. Differentiating between pain/agitation and paedED migth not always be easy. Age-adapted scores should always be applied. Main focus in the prevention of paedED is the reduction of anxiety. The way this is achieved by the dedicated pediatric anesthesia teams caring for children, e.g. by oral midazolam, clowns, music, smartphone induction, does not matter. Using α2-agonists in the perioperative phase and applying propofol seems to be effective. A quiet supportive environment for recovery adds to a relaxed, stress-free awakening. For the future detecting paedED on normal wards becomes an important issue. This may be achieved by structured interviews or questionnaires assessing postoperative negative behavioural changes at the same time.

Improvement of polytrauma management-quality inspection of a newly introduced course concept.

RATIONALE, AIMS, AND OBJECTIVES: A systematic literature search for training course concepts for care of severely injured and severely ill patients respecting improvement of process and outcome yielded little data. For several years, the University Hospital of Bonn has hosted a shock-room management course which, on the one hand, communicates human factor aspects and, on the other hand, pursues interdisciplinary and interprofessional team training. The Bonn shock-room management course (BSM-course®) differs from other courses in both format and principles. The aim of this study was to evaluate the quality of the structure of the course based on course evaluations of participants and its impact on the quality of the process and results for polytrauma care. METHODS: Single-center retrospective evaluation study (2011 to 2014). It was based on data from simulator training and records from the German Trauma Registry (DGU)®. RESULTS: Subjective evaluation of participants (n = 188) of the structure quality of Bonn's shock-room management course was overall positive. Objective measures of course participant performance also improved during simulation training (P = 0.012). An increasing number of trained employees also had a positive influence in reducing process time for shock-room care. Further, the course likewise had a positive impact on documentation quality (degree of completion), with regard to 4 relevant predictive parameters. Early mortality during the first 24 hours remained constant at 6.0-6.5% between 2011 and 2013, yet it decreased to 3.1% in 2014. CONCLUSION: The BSM-course® represents a symbiosis of horizontal team approach of trauma care and human factor training. The course format is able to ensure interdisciplinary and interprofessional team training with a high degree of efficiency. Furthermore, the presented work shows that a modern course concept can improve the quality of trauma care.

Early post-treatment FDG PET predicts survival after 90Y microsphere radioembolization in liver-dominant metastatic colorectal cancer.

PURPOSE: The aim of this study was to evaluate the predictive value of early metabolic response 4 weeks post-treatment using (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT in patients with unresectable hepatic metastases of colorectal cancer (CRC) undergoing radioembolization (RE) with (90)Y-labelled microspheres. METHODS: A total of 51 consecutive patients with liver-dominant metastases of CRC were treated with RE and underwent (18)F-FDG PET/CT at baseline and 4 weeks after RE. In each patient, three hepatic metastases with the highest maximum standardized uptake value (SUVmax) were selected as target lesions. Metabolic response was defined as >50 % reduction of tumour to liver ratios. Survival analyses using Kaplan-Meier and multivariate analyses were performed to identify prognostic factors for overall survival (OS). Investigated baseline characteristics included age (>60 years), performance status (Eastern Cooperative Oncology Group >1), bilirubin (>1.0 mg/dl), hepatic tumour burden (>25 %) and presence of extrahepatic disease. RESULTS: The median OS after RE was 7 months [95 % confidence interval (CI) 5-8]; early metabolic responders (n = 33) survived longer than non-responders (p < 0.001) with a median OS of 10 months (95 % CI 3-16) versus 4 months (95 % CI 2-6). Hepatic tumour burden also had significant impact on treatment outcome (p < 0.001) with a median OS of 5 months (95 % CI, 3-7) for patients with >25 % metastatic liver replacement vs 14 months (95 % CI 6-22) for the less advanced patients. Both factors (early metabolic response and low hepatic tumour burden) remained as independent predictors of improved survival on multivariate analysis. CONCLUSION: These are the first findings to show that molecular response assessment in CRC using (18)F-FDG PET/CT appears feasible as early as 4 weeks post-RE, allowing risk stratification and potentially facilitating early response-adapted treatment strategies.
