Association of prehospital invasive blood pressure measurement and treatment times of intubated patients with suspected stroke - a retrospective study.

Background: Invasive blood pressure measurement is commonly used in in-hospital patients with stroke requiring general anesthesia, but is much less established in the prehospital setting. While it allows for more precise blood pressure management, it might also lead to prehospital treatment delays. Therefore, this study aims to evaluate the potential impact of prehospital invasive blood pressure measurement on treatment times.

Effects of departmental green anaesthesia interventions on carbon dioxide equivalent emissions: a systematic review.

Background: Anaesthesia contributes to greenhouse gas emissions and can play a crucial role in reducing the carbon footprint of the global healthcare sector. The aim of this systematic review is to identify which departmental interventions influence estimated carbon dioxide (CO) equivalent emissions of anaesthesia and to quantify their reductions.

Methods: A systematic literature search was conducted through four major electronic databases (Cochrane Library, Embase, MEDLINE, and PubMed) for studies investigating the changes in CO equivalent emissions per anaesthetic before and after departmental green anaesthesia interventions.

Assessment of frontal EEG measurement in out-of-hospital cardiac arrest: a prospective observational feasibility study - study protocol.

Introduction: Nowadays, managing out-of-hospital cardiac arrest (OHCA) prioritises measures that achieve a good neurological outcome. Monitoring neurological function early is an essential step in identifying patients who could benefit from invasive techniques, such as extracorporeal membrane oxygenation, compared with patients suffering from irreversible hypoxic-ischaemic brain injury. Electroencephalography (EEG) has been used in the hospital; thus, its prehospital data are lacking.

Resuscitative endovascular balloon occlusion of the aorta for trauma patients with uncontrolled hemorrhage: a retrospective target trial emulation (the AT-REBOA target trial).

Background: Noncompressible truncal hemorrhage is a major contributor to preventable deaths in trauma patients and, despite advances in emergency care, still poses a big challenge.

Objectives: This study aimed to assess the clinical efficacy of trauma resuscitation care incorporating Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) compared to standard care for managing uncontrolled torso or lower body hemorrhage.

Methods: This study utilized a target trial design with a matched case-control methodology, emulating randomized 1 : 1 allocation for patients receiving trauma resuscitation care with or without the use of REBOA.

Available equipment for traumatic haemorrhage management in Austrian prehospital physician response units: a nationwide survey and analysis of guideline adherence.

Background: Traumatic injuries, particularly those involving massive bleeding, remain a leading cause of preventable deaths in prehospital settings. The availability of appropriate emergency equipment is crucial for effectively managing these injuries, but the variability in equipment across different response units can impact the quality of trauma care. This prospective survey study evaluated the availability of prehospital equipment for managing bleeding trauma patients in Austria.

Sex specific differences in short-term mortality after ICU-delirium.

Introduction: Delirium is a frequent complication in critically ill patients and is associated with adverse outcomes such as long-term cognitive impairment and increased mortality. It is unknown whether there are sex-related differences in intensive care unit (ICU) delirium and associated outcomes. We aimed to assess sex-specific differences in short-term mortality following ICU-delirium.

Utilization of Multi-Parameter Blood Gas Analysis in Prehospital Emergency Medicine-A Scoping Review.

Background: Prehospital blood gas analysis (BGA) is an evolving field that offers the potential for early identification and management of critically ill patients. However, the utility and accuracy of prehospital BGA are subjects of ongoing debate.

Objectives: We aimed to provide a comprehensive summary of the current literature on prehospital BGA, including its indications, methods, and feasibility.

Hyperkalaemia in bleeding trauma patients: A potential marker of disease severity - A retrospective cohort study.

Background: Hyperkalaemia is a common electrolyte abnormality seen in critically ill patients. In haemorrhagic shock, it may contribute to cardiac arrest and has been identified as a potential marker for tissue hypoxia. However, the significance of its role in haemorrhagic shock and its contribution to mortality remains unclear.

Use of bitemporal NACA score documentation in prehospital emergency medical services- a retrospective study.

Background: The assessment of illness severity in the prehospital setting is essential for guiding appropriate medical interventions. The National Advisory Committee for Aeronautics (NACA) score is a validated tool commonly used for this purpose. However, the potential benefits of using bitemporal documentation of NACA scores to capture the dynamic changes in emergency situations remain uncertain.

Association of prehospital lactate levels with base excess in various emergencies - a retrospective study.

Objectives: Blood gas analysis, including parameters like lactate and base excess (BE), is crucial in emergency medicine but less commonly utilized prehospital. This study aims to elucidate the relationship between lactate and BE in various emergencies in a prehospital setting and their prognostic implications.

Methods: We conducted a retrospective analysis of prehospital emergency patients in Graz, Austria, from October 2015 to November 2020.

Out-of-Hospital Arterial to End-Tidal Carbon Dioxide Gradient in Patients With Return of Spontaneous Circulation After Out-of-Hospital Cardiac Arrest: A Retrospective Study.

Study Objective: End-tidal carbon dioxide (etCO) is used to guide ventilation after achieving return of spontaneous circulation (ROSC) in certain out-of-hospital systems, despite an unknown difference between arterial and end-tidal CO (partial pressure of carbon dioxide [paCO]-etCO difference) levels in this population. The primary aim of this study was to evaluate and quantify the paCO-etCO difference in out-of-hospital patients with ROSC after nontraumatic cardiac arrest.

Methods: This retrospective single-center study included patients aged 18 years and older with sustained ROSC after nontraumatic out-of-hospital cardiac arrest.

PerIoperative iNflammatory reSponse assessment In hiGH-risk patienTs undergoing non-cardiac surgery (INSIGHT): study protocol of a prospective non-interventional observational study.

Introduction: Increased inflammatory processes after non-cardiac surgery are very common. The association between postoperative inflammation and the occurrence of cardiovascular complications after non-cardiac surgery are still not entirely clear. Therefore, we will evaluate the association between postoperative inflammation and the occurrence of major cardiovascular complications in patients at-risk for cardiovascular complications undergoing non-cardiac surgery.

Mechanical ventilation with ten versus twenty breaths per minute during cardio-pulmonary resuscitation for out-of-hospital cardiac arrest: A randomised controlled trial.

Aim Of The Study: This study sought to assess the effects of increasing the ventilatory rate from 10 min to 20 min using a mechanical ventilator during cardio-pulmonary resuscitation (CPR) for out-of-hospital cardiac arrest (OHCA) on ventilation, acid-base-status, and outcomes.

Methods: This was a randomised, controlled, single-centre trial in adult patients receiving CPR including advanced airway management and mechanical ventilation offered by staff of a prehospital physician response unit (PRU). Ventilation was conducted using a turbine-driven ventilator (volume-controlled ventilation, tidal volume 6 ml per kg of ideal body weight, positive end-expiratory pressure (PEEP) 0 mmHg, inspiratory oxygen fraction (FiO) 100%), frequency was pre-set at either 10 or 20 breaths per minute according to week of randomisation.

Association of immediate versus delayed extubation of patients admitted to intensive care units postoperatively and outcomes: A retrospective study.

Aim Of This Study: This study seeks to investigate, whether extubation of tracheally intubated patients admitted to intensive care units (ICU) postoperatively either immediately at the day of admission (day 1) or delayed at the first postoperative day (day 2) is associated with differences in outcomes.

Materials And Methods: We performed a retrospective analysis of data from an Austrian ICU registry. Adult patients admitted between January 1st, 2012 and December 31st, 2019 following elective and emergency surgery, who were intubated at the day 1 and were extubated at day 1 or day 2, were included.

Methods: The study analysed the knowledge and willingness to perform BLS of laypersons passing an AED at a public train station. Interviewees were recruited at two time points before and after a four year-long structured regional awareness campaign, which focused on , , in a mid-size European city (270,000 inhabitants).

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.

A retrospective cohort study on association of age and physician decision making for or against rapid sequence intubation in unconscious patients.

In unconscious individuals, rapid sequence intubation (RSI) may be necessary for cardiopulmonary stabilisation and avoidance of secondary damage. Opinions on such invasive procedures in people of older age vary. We thus sought to evaluate a possible association between the probability of receiving prehospital RSI in unconsciousness and increasing age.
