Carvedilol-enriched cold oxygenated blood cardioplegia improves left ventricular diastolic function after weaning from cardiopulmonary bypass
Dahle, Geir Olav; Salminen, Pirjo-Riitta; Moen, Christian Arvei; Eliassen, Finn; Nygreen, Else Loholdt; Kytö, Ville; Saukko, Pekka; Haaverstad, Rune; Matre, Knut; Grong, Ketil (Peer reviewed; Journal article, 2016-08)Objectives: To investigate whether adding carvedilol, a nonselective β- and selective α1-receptor blocking agent with antioxidant properties, to oxygenated blood cardioplegia improves myocardial function after weaning from ... -
Esmolol added in repeated, cold, oxygenated blood cardioplegia improves myocardial function after cardiopulmonary bypass
Dahle, Geir Olav; Salminen, Pirjo-Riitta; Moen, Christian Arvei; Eliassen, Finn; Jonassen, Anne K.; Haaverstad, Rune; Matre, Knut; Grong, Ketil (Peer reviewed; Journal article, 2015-06)Objective: This study investigated if the β-receptor blocking agent esmolol, added to standard oxygenated blood cardioplegia, improved myocardial function after weaning from bypass. Design: A block-randomized, blinded ... -
The influence of acute unloading on left ventricular strain and strain rate by speckle tracking echocardiography in a porcine model
Dahle, Geir Olav; Stangeland, Lodve; Moen, Christian Arvei; Salminen, Pirjo-Riitta; Haavestad, Rune; Matre, Knut; Grong, Ketil (Peer reviewed; Journal article, 2016)Noninvasive measurements of myocardial strain and strain rate by speckle tracking echocardiography correlate to cardiac contractile state but also to load, which may weaken their value as indices of inotropy. In a porcine ... -
Left ventricular dysfunction after two hours of polarizing or depolarizing cardioplegic arrest in a porcine model
Aass, Terje; Stangeland, Lodve; Moen, Christian Arvei; Solholm, Atle; Dahle, Geir Olav; Chambers, David J.; Urban, Malte; Nesheim, Knut; Haaverstad, Rune; Matre, Knut; Grong, Ketil (Peer reviewed; Journal article, 2019)Introduction: This experimental study compares myocardial function after prolonged arrest by St. Thomas’ Hospital polarizing cardioplegic solution (esmolol, adenosine, Mg2+) with depolarizing (hyperkalaemic) St. Thomas’ ... -
Myocardial function after polarizing versus depolarizing cardiac arrest with blood cardioplegia in a porcine model of cardiopulmonary bypass
Aass, Terje; Stangeland, Lodve; Moen, Christian Arvei; Salminen, Pirjo-Riitta; Dahle, Geir Olav; Chambers, David J.; Markou, Thomais; Eliassen, Finn; Urban, Malte; Haaverstad, Rune; Matre, Knut; Grong, Ketil (Peer reviewed; Journal article, 2016)OBJECTIVES Potassium-based depolarizing St Thomas' Hospital cardioplegic solution No 2 administered as intermittent, oxygenated blood is considered as a gold standard for myocardial protection during cardiac surgery. ... -
Reperfusion Therapy with Low-Dose Insulin or Insulin-Like Growth Factor 2; Myocardial Function and Infarct Size in a Porcine Model of Ischaemia and Reperfusion
Salminen, Pirjo-Riitta; Dahle, Geir Olav; Moen, Christian Arvei; Wergeland, Anita; Jonassen, Anne Kristin; Haaverstad, Rune; Matre, Knut; Grong, Ketil (Peer reviewed; Journal article, 2014-05-19)In an open-chest porcine model, we examined whether myocardial pharmacological conditioning at the time of reperfusion with low-dose insulin or insulin-like growth factor 2 (IGF2), not affecting serum glucose levels, could ... -
Vocal Cord Function During Recurrent Laryngeal Nerve Injury Assessed by Accelerometry and EMG
Dahle, Geir Olav; Setså, Erling Johan; Svendsen, Øyvind Sverre; Stangeland, Lodve; Heimdal, John-Helge; Henriksen, Bård; Husby, Paul; Brauckhoff, Katrin (Peer reviewed; Journal article, 2019-08-02)Objective Gradual impairment of nerve conduction is expected to be tightly associated with simultaneous gradual loss of vocal cord contractility, related to the fact that injured axons are connected to a defined number of ...
