Management of Severe Burn Wounds Colonized With Multi-resistant Pseudomonas aeruginosa and Fusarium Using Marine Omega3 Wound Matrix in a Female Victim of War.

War-related burns are common injuries, also among the civilian population. Additional trauma such as fractures or shrapnel wounds may add significant morbidity. Burn injuries in war zones are furthermore frequently undertreated and hence prone to complications. We report a case of a young female victim of war, whose severely infected burn wounds could be successfully healed using a combination of targeted antimicrobial therapy, wound conditioning using decellularized fish skin, and subsequent skin grafting.

Physician utilization in prehospital emergency medical services in Europe: an overview and comparison. / Visión general y comparación de la presencia de médicos en los servicios de emergencias médicas prehospitalarios en Europa.

OBJECTIVES: National and regional systems for emergency medical care provision may differ greatly. We sought to determine whether or not physicians are utilized in prehospital care and to what extent they are present in differentEuropean countries. MATERIAL AND METHODS: We collected information on 32 European countries by reviewing publications and sending questionnaires to authors of relevant articles as well as to officials of ministries of health (or equivalent), representatives of national societies in emergency medicine, or well-known experts in the specialty. RESULTS: Thirty of the 32 of European countries we studied (94%) employ physicians in prehospital emergency medical services. In 17 of the 32 (53%), general practitioners also participate in prehospital emergency care. Emergency system models were described as Franco-German in 27 countries (84%), as hybrid in 17 (53%), and as Anglo-American in 14 (44%). Multiple models were present simultaneously in 17 countries (53%). We were able to differentiate between national prehospital emergency systems with a novel classification based on tiers reflecting the degree of physician utilization in the countries. We also grouped the national systems by average population and area served. CONCLUSION: There are notable differences in system designs and intensity of physician utilization between different geographic areas, countries, and regions in Europe. Several archetypal models (Franco-German, hybrid, and Anglo- American) exist simultaneously across Europe.

Data for: Reliability of mechanical ventilation during continuous chest compressions: A crossover study of transport ventilators in a human cadaver model of CPR.

The data presented in this article relate to the research article, "Reliability of mechanical ventilation during continuous chest compressions: a crossover study of transport ventilators in a human cadaver model of CPR" [1]. This article contains raw data of continuous recordings of airflow, airway and esophageal pressure during the whole experiment. Data of mechanical ventilation was obtained under ongoing chest compressions and from repetitive measurements of pressure-volume curves. All signals are presented as raw time series data with a sample rate of 200Hz for flow and 500 Hz for pressure. Additionally, we hereby publish extracted time series recordings of force and compression depth from the used automated chest compression device. Concomitantly, we report tables with time stamps from our laboratory book by which the data can be sequenced into different phases of the study protocol. We also present a dataset of derived volumes which was used for statistical analysis in our research article together with the used exclusion list. The reported dataset can help to understand mechanical properties of Thiel-embalmed cadavers better and compare different models of cardiopulmonary resuscitation (CPR). Future research may use this data to translate our findings from bench to bedside. Our recordings may become useful in developing respiratory monitors for CPR, especially in prototyping and testing algorithms of such devices.

Evaluation of the usefulness of non-invasive serum haemoglobin measurement in a perioperative setting in a prospective observational study.

Patient Blood Management (PBM) programmes seek to reduce the number of missed anaemic patients in the run-up to surgery. The aim of this study was to evaluate the usefulness of haemoglobin (Hb) measured non-invasively (SpHb) in preoperative screening for anaemia. We conducted a prospective observational study in a preoperative clinic. Adult patients undergoing examination for surgery who had their Hb measured by laboratory means also had their Hb measured non-invasively by a trained health care provider. 1216 patients were recruited. A total of 109 (9.3%) patients (53 men and 56 women) was found to be anaemic by standard laboratory Hb measurement. Sensitivity for SpHb to detect anaemic patients was 0.50 (95% CI 0.37-0.63) in women and 0.30 (95% CI 0.18-0.43) in men. Specificity was 0.97 (95% CI 0.95-0.98) in men and 0.93 (95% CI 0.84-1.0) in women. The rate of correctly classified patients was 84.7% for men and 89.4% for women. Positive predictive value for SpHb was 0.50 (95% CI 0.35-0.65) in men and 0.40 (95% CI 0.31-0.50) in women; negative predictive value was 0.93 (95% CI 0.92-0.94) in men and 0.95 (95% CI 0.94-0.96) in women. We conclude that due to low sensitivity, SpHb is poorly suitable for detecting preoperative anaemia in both sexes under standard of care conditions.

Reliability of mechanical ventilation during continuous chest compressions: a crossover study of transport ventilators in a human cadaver model of CPR.

BACKGROUND: Previous studies have stated that hyperventilation often occurs in cardiopulmonary resuscitation (CPR) mainly due to excessive ventilation frequencies, especially when a manual valve bag is used. Transport ventilators may provide mandatory ventilation with predetermined tidal volumes and without the risk of hyperventilation. Nonetheless, interactions between chest compressions and ventilations are likely to occur. We investigated whether transport ventilators can provide adequate alveolar ventilation during continuous chest compression in adult CPR. METHODS: A three-period crossover study with three common transport ventilators in a cadaver model of CPR was carried out. The three ventilators 'MEDUMAT Standard²', 'Oxylog 3000 plus', and 'Monnal T60' represent three different interventions, providing volume-controlled continuous mandatory ventilation (VC-CMV) via an endotracheal tube with a tidal volume of 6 mL/kg predicted body weight. Proximal airflow was measured, and the net tidal volume was derived for each respiratory cycle. The deviation from the predetermined tidal volume was calculated and analysed. Several mixed linear models were calculated with the cadaver as a random factor and ventilator, height, sex, crossover period and incremental number of each ventilation within the period as covariates to evaluate differences between ventilators. RESULTS: Overall median deviation of net tidal volume from predetermined tidal volume was - 21.2 % (IQR: 19.6, range: [- 87.9 %; 25.8 %]) corresponding to a tidal volume of 4.75 mL/kg predicted body weight (IQR: 1.2, range: [0.7; 7.6]). In a mixed linear model, the ventilator model, the crossover period, and the cadaver's height were significant factors for decreased tidal volume. The estimated effects of tidal volume deviation for each ventilator were - 14.5 % [95 %-CI: -22.5; -6.5] (p = 0.0004) for 'Monnal T60', - 30.6 % [95 %-CI: -38.6; -22.6] (p < 0.0001) for 'Oxylog 3000 plus' and - 31.0 % [95 %-CI: -38.9; -23.0] (p < 0.0001) for 'MEDUMAT Standard²'. CONCLUSIONS: All investigated transport ventilators were able to provide alveolar ventilation even though chest compressions considerably decreased tidal volumes. Our results support the concept of using ventilators to avoid excessive ventilatory rates in CPR. This experimental study suggests that healthcare professionals should carefully monitor actual tidal volumes to recognise the occurrence of hypoventilation during continuous chest compressions.

Is There an Impact of Sex on Acute Postthoracotomy Pain? A Retrospective Analysis.

BACKGROUND: Current knowledge about sex-related differences states that pain is generally more frequent and intense in women. Because severe postthoracotomy pain is associated with complications, sufficient pain control is essential. Data on sex-related aspects in the context of pain after thoracotomy are scarce. The study attempted to determine whether sex significantly affects pain and pain treatment after thoracotomy. METHODS: This retrospective study assessed visual analogue scale (VAS) scores and analgesic consumption (opioids and diclofenac) during the first 5 days after surgery and the point in time when analgesics were changed from the intravenous to the oral route in patients who had open lung surgery. The influences of sex, PCEA (patient-controlled epidural analgesia), age, and surgical factors were evaluated with mixed-model analysis. RESULTS: The study was able to include 344 patients (130 female, 214 male). The VAS scores model did not consider sex as relevant. The opioid model showed a PCEA-time-sex interaction with increasing opioid demand after day 3 that predominantly affected male patients (P < .001). Diclofenac doses where significantly higher in an interaction of female sex and small extent of surgery (P = .007). Posterolateral thoracotomy led to significantly higher VAS scores (P < .001) and higher demand for opioids (P = .007) and diclofenac (P = .012). CONCLUSIONS: The study concluded that there are no general sex-related differences in pain intensity and analgesic requirement after thoracotomy. Anterolateral thoracotomy was the less painful surgical approach. PCEA had favorable results, although there seemed to a rebound pain phenomenon after epidural catheter removal on postoperative day 3 that mainly affected male patients.
