An assessment of long-term complications following prehospital intraosseous access: A nationwide study.

Background: The guidelines for Advanced Life Support issued by the European Resuscitation Council recommend considering drug delivery through intraosseous access if intravenous access to the vascular bed is not feasible or unsuccessful. Emergency prehospital intraosseous cannulation may theoretically lead to an increased risk of long-term complications such as osteomyelitis, osteonecrosis, or compartment syndrome. Such complications have previously been reported in case reports or small sample case series.

Head injuries related to bicycle collisions and helmet use - an observational study.

Objectives: In Denmark, the use of bicycles is widespread, and head injuries are often seen in cyclists involved in collisions. Despite the well-known effects of using a helmet to reduce head injuries, using helmets is not mandatory in Denmark. The primary objective of this study was to provide data regarding injury outcomes and helmet usage.

Treat and release: an observational study of non-conveyed high-acuity dispatches in a Danish emergency medical system.

Non-conveyance refers to the practice of treating a patient on-site without transporting them to a medical facility. It may decrease unnecessary hospital transfers and improve patient satisfaction. Nonetheless, ensuring patient safety remains paramount.

Foreign body airway obstruction resulting in out-of-hospital cardiac arrest in Denmark - Incidence, survival and interventions.

Background: Foreign body airway obstruction (FBAO) stands as an important contributor to accidental fatalities, yet prompt bystander interventions have been shown to improve survival. This study aimed to evaluate the incidence, interventions, and survival outcomes of patients with out-of-hospital cardiac arrest (OHCA) related to FBAO in comparison to patients with non-FBAO OHCA.

Methods: In this population-based cohort study, we included all OHCAs in Denmark from 2016 to 2022.

Characteristics and critical care interventions in drowning patients treated by the Danish Air Ambulance from 2016 to 2021: a nationwide registry-based study with 30-day follow-up.

Background: Improving oxygenation and ventilation in drowning patients early in the field is critical and may be lifesaving. The critical care interventions performed by physicians in drowning management are poorly described. The aim was to describe patient characteristics and critical care interventions with 30-day mortality as the primary outcome in drowning patients treated by the Danish Air Ambulance.

Prehospital interventions and outcomes in traumatic cardiac arrest: a population-based cohort study using the Danish Helicopter Emergency Medical Services data.

Background And Importance: Traumatic cardiac arrest is associated with poor prognosis, and timely evidence-based treatment is paramount for increasing survival rates. Physician-staffed helicopter emergency medical service use in major trauma has demonstrated improved outcomes. However, the sparsity of data highlights the necessity for a comprehensive understanding of the epidemiology of traumatic cardiac arrest.

Association between using a prehospital assessment unit and hospital admission and mortality: a matched cohort study.

Objectives: This study aimed to compare hospital admission and 30-day mortality between patients assessed by the prehospital assessment unit (PAU) and patients not assessed by the PAU.

Design: This was a matched cohort study.

Setting: This study was conducted between November 2021 and October 2022 in Region Zealand, Denmark.

Danish Drowning Formula for identification of out-of-hospital cardiac arrest from drowning.

Background: Accurate, reliable, and sufficient data is required to reduce the burden of drowning by targeting preventive measures and improving treatment. Today's drowning statistics are informed by various methods sometimes based on data sources with questionable reliability. These methods are likely responsible for a systematic and significant underreporting of drowning.

Traumatic cardiac arrest - a nationwide Danish study.

Background: Cardiac arrest following trauma is a leading cause of death, mandating urgent treatment. This study aimed to investigate and compare the incidence, prognostic factors, and survival between patients suffering from traumatic cardiac arrest (TCA) and non-traumatic cardiac arrest (non-TCA).

Methods: This cohort study included all patients suffering from out-of-hospital cardiac arrest in Denmark between 2016 and 2021.

Training in Basic Life Support and Bystander-Performed Cardiopulmonary Resuscitation and Survival in Out-of-Hospital Cardiac Arrests in Denmark, 2005 to 2019.

Importance: Strategies to improve survival from out-of-hospital cardiac arrest (OHCA) include mass education of laypersons with no official duty to respond to OHCA. In Denmark, basic life support (BLS) course attendance has been mandated by law in October 2006 for obtaining a driver's license for all vehicles and in vocational education programs.

Objectives: To examine the association between yearly BLS course participation rate and bystander cardiopulmonary resuscitation (CPR) and 30-day survival from OHCA and to examine if bystander CPR rate acted as a mediator on the association between mass education of laypersons in BLS and survival from OHCA.

AED applied, not recommending defibrillation - A validation study of the new variable AED in the Danish Cardiac Arrest Registry.

Aim: This study aimed to design and implement a new variable, the automated external defibrillator (AED) variable, within the Danish Cardiac Arrest Registry. The introduction of the new variable aims to investigate and solve the challenges of reporting out-of-hospital cardiac arrests.

Methods: This validation study examined all patients with out-of-hospital cardiac arrest from 2016 to 2019.

Noninvasive intracranial pressure monitoring in central nervous system infections.

Intracranial pressure (ICP) monitoring constitutes an important part of the management of traumatic brain injury. However, its application in other brain pathologies such as neuroinfections like acute bacterial meningitis is unclear. Despite focus on aggressive, prompt treatment, morbidity and mortality from acute bacterial meningitis remain high.

Pediatric out-of-hospital cardiac arrest in Denmark.

Background: Pediatric out-of-hospital cardiac arrest (POHCA) has received limited attention. All causes of POHCA and outcomes were examined during a 4-year period in a Danish nationwide register and prehospital medical records. The aim was to describe the incidence, reversible causes, and survival rates for POHCA in Denmark.

Out-of-hospital cardiac arrest related to exercise in the general population: Incidence, survival and bystander response.

Background: Regular exercise is known to prevent cardiovascular disorders, but it may also trigger acute cardiac events. This study examined the incidence, prognosis, and outcomes of out-of-hospital cardiac arrest (OHCA) related to exercise in the general population of Denmark.

Methods: This retrospective cohort study examined all the OHCAs in the Danish Cardiac Arrest Registry from 2016 to 2019.

[Intracerebral haemorrhage twelve days after vaccination with ChAdOx1 nCoV-19].

The COVID-19-pandemic has had a huge impact on health and economics all over the world resulting in widespread vaccine development. Vaccine-induced immune thrombotic thrombocytropenia has been described, suggesting a link between the two adeno-vector vaccines ChAdOx1 nCoV-19 (Vaxzevria from AstraZeneca) and Ad26.COV2-S (Janssen from Johnson and Johnson).

Position-Related Postoperative Peripheral Neuropathy After Laparoscopic Colorectal Surgery: A Comparative Single-Center Prospective Cohort Study.

Laparoscopic colorectal surgery requires perioperative positioning in the dorsal lithotomy position and intermittent Trendelenburg position. This position is associated with postoperative peripheral neuropathy (PPN), which is a substantial cause of anesthesia-related claims. The objective of this study was to assess the incidence of PPN of patients positioned in lithotomy position with shoulder braces, and second to compare this group with patients positioned on the foam mattress Pink Pad.
