    • Hands-free continuous carotid Doppler ultrasound for detection of the pulse during cardiac arrest in a porcine model 

      Faldaas, Bjørn Ove; Nielsen, Erik Waage; Storm, Benjamin; Lappegård, Knut Tore; How, Ole-Jakob; Nilsen, Bent Aksel; Kiss, Gabriel Hanssen; Skogvoll, Eirik; Torp, Hans; Ingul, Charlotte Ingeborg Björk (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-20)
      Background/Purpose - Pulse palpation is an unreliable method for diagnosing cardiac arrest. To address this limitation, continuous hemodynamic monitoring may be a viable solution. Therefore, we developed a novel, hands-free Doppler system, RescueDoppler, to detect the pulse continuously in the carotid artery.<p> <p>Methods - In twelve pigs, we evaluated RescueDoppleŕs potential to measure blood ...

    • Intraosseous fluid resuscitation causes systemic fat emboli in a porcine hemorrhagic shock model 

      Kristiansen, Steinar; Storm, Benjamin; Dahle, Dalia; Josefsen, Terje D.; Dybwik, Knut Gustav; Nilsen, Bent Aksel; Nielsen, Erik Waage (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-20)
      Background: Intraosseous cannulation can be life-saving when intravenous access cannot be readily achieved. However, it has been shown that the procedure may cause fat emboli to the lungs and brain. Fat embolization may cause serious respiratory failure and fat embolism syndrome. We investigated whether intraosseous fluid resuscitation in pigs in hemorrhagic shock caused pulmonary or systemic ...

    • Venous Air Embolism Activates Complement C3 Without Corresponding C5 Activation and Trigger Thromboinflammation in Pigs 

      Storm, Benjamin; Ludviksen, Judith K; Christiansen, Dorte; Fure, Hilde; Pettersen, Kristin; Landsem, Anne; Nilsen, Bent Aksel; Dybwik, Knut Gustav; Braaten, Tonje; Nielsen, Erik Waage; Mollnes, Tom Eirik (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-15)
      Introduction: Air embolism may complicate invasive medical procedures. Bubbles trigger complement C3-mediated cytokine release, coagulation, and platelet activation in vitro in human whole blood. Since these findings have not been verified in vivo, we aimed to examine the effects of air embolism in pigs on thromboinflammation.<p> <p>Methods: Forty-five landrace pigs, average 17 kg (range 8.5-30), ...
