Purpose: Anaemia is one of the leading causes of death among severely injured patients. It is also known to increase the risk of death and prolong the length of hospital stay in various surgical groups. The main objective of this study is to analyse the anaemia rate on admission to the emergency department and the impact of anaemia on in-hospital mortality.
Methods: Data from the TraumaRegister DGU® (TR-DGU) between 2015 and 2019 were analysed. Inclusion criteria were age ≥ 16 years and most severe Abbreviated Injury Scale (AIS) score ≥ 3. Patients were divided into three anaemia subgroups: no or mild anaemia (NA), moderate anaemia (MA) and severe anaemia (SA). Pre-hospital data, patient characteristics, treatment in the emergency room (ER), outcomes, and differences between trauma centres were analysed.
Results: Of 67,595 patients analysed, 94.9% (n = 64,153) exhibited no or mild anaemia (Hb ≥ 9 g/dl), 3.7% (n = 2478) displayed moderate anaemia (Hb 7–8 g/dl) and 1.4% (n = 964) presented with severe anaemia (Hb < 7 g/dl). Haemoglobin (Hb) values ranged from 3 to 18 g/dl with a mean Hb value of 12.7 g/dl. In surviving patients, anaemia was associated with prolonged length of stay (LOS). Multivariate logistic regression analyses revealed moderate (p < 0.001 OR 1.88 (1.66–2.13)) and severe anaemia (p < 0.001 OR 4.21 (3.46–5.12)) to be an independent predictor for mortality. Further significant predictors are ISS score per point (OR 1.0), age 70–79 (OR 4.8), age > 80 (OR 12.0), severe pre-existing conditions (ASA 3/4) (OR 2.26), severe head injury (AIS 5/6) (OR 4.8), penetrating trauma (OR 1.8), unconsciousness (OR 4.8), shock (OR 2.2) and pre-hospital intubation (OR 1.6).
Conclusion: The majority of severely injured patients are admitted without anaemia to the ER. Injury-associated moderate and severe anaemia is an independent predictor of mortality in severely injured patients.
Introduction Patients undergoing heart valve surgery are predominantly transferred postoperatively to the intensive care unit (ICU) under continuous sedation. Volatile anaesthetics are an increasingly used treatment alternative to intravenous substances in the ICU. As subject to inhalational uptake and elimination, the resulting pharmacological benefits have been repeatedly demonstrated. Therefore, volatile anaesthetics appear suitable to meet the growing demands of fast-track cardiac surgery. However, their use requires special preparation at the bedside and trained medical and nursing staff, which might limit the pharmacological benefits. The aim of our work is to assess whether the temporal advantages of recovery under volatile sedation outweigh the higher effort of special preparation.
Methods and analysis The study is designed to evaluate the differences between intravenous sedatives (n=48) and volatile sedatives (n=48) in continued intensive care sedation. This study will be conducted as a prospective, randomised, controlled, single-blinded, monocentre trial at a German university hospital in consenting adult patients undergoing heart valve surgery at a university hospital. This observational study will examine the necessary preparation time, staff consultation and overall feasibility of the chosen sedation method. For this purpose, the continuation of sedation in the ICU with volatile sedatives is considered as one study arm and with intravenous sedatives as the comparison group. Due to rapid elimination and quick awakening after the termination of sedation, closer consultation between the attending physician and the ICU nursing staff is required, in addition to a prolonged setup time. Study analysis will include the required setup time, time from admission to extubation as primary outcome and neurocognitive assessability. In addition, possible operation-specific (blood loss, complications), treatment parameters (catecholamine dosages, lung function) and laboratory results (acute kidney injury, acid base balance (lactataemia), liver failure) as influencing factors will be collected. The study-relevant data will be extracted from the continuous digital records of the patient data management system after the patient has been discharged from the ICU. For statistical evaluation, 95% CIs will be calculated for the median time to extubation and neurocognitive assessability, and the association will be assessed with a Cox regression model. In addition, secondary binary outcome measures will be evaluated using Fisher’s exact tests. Further descriptive and exploratory statistical analyses are also planned.
Ethics and dissemination The study was approved by the Institutional Ethics Board of the University of Frankfurt, Germany (#20-1050). Informed consent of all individual patients will be obtained before randomisation. Results will be disseminated via publication in peer-reviewed journals.
Epidural catheterization has become an indispensable part of modern pain therapy, for example, in obstetrics. Learning how to master this skill is an important competency. Videos are among the information sources with the highest information content for learning such skills. The present study aims to analyze videos regarding epidural catheter placement provided on the YouTube platform based on a validated checklist. An expert workshop selected crucial items for learning epidural catheterization in obstetrics. Items were identified and optimized in a five-step testing process. Using this checklist, videos from YouTube were evaluated by eleven health care professionals. Sixteen videos were identified and analyzed. Concerning the catheterization-specific part of the checklist, only two videos showed satisfactory quality. In the didactic part, eleven out of 21 items reached a mean score >50% of the points. Regarding interrater reliability, the catheterization-specific checklist was shown to be substantial (Fleiss’ kappa = 0.610), and the didactic part was shown to be fair (Fleiss’ kappa = 0.401). Overall, standard monitoring and appropriate aseptic technique were followed in only 42% and 49% for the procedure. There was a significant correlation between the runtime and the content quality (p < 0.001). No correlation could be found in terms of platform rating parameters. The video quality varied highly in terms of the requirements of this practical skill. The majority appear unsuitable for self-study due to serious errors and deficiencies regarding patient safety. However, there is no quality control on free platforms. Accordingly, it is difficult to identify suitable videos for educational purposes.
