The aim of this PhD thesis was to provide a continuous method to monitor myocardial function during cardiac surgery with the superior sensitivity of ultrasonic technique and the continuity of electrocardiographic (ECG) monitoring. ⋯ The provided ultrasound system could give continuous real-time monitoring of myocardial function, and detect myocardial dysfunction with superior sensitivity than ECG or hemodynamic monitoring. This could be used for improved monitoring of myocardial function during cardiac surgery.

Observational StudyConcentrations of remifentanil, propofol, fentanyl, and midazolam during rewarming from therapeutic hypothermia.
The clearance of sedatives and analgesics may be reduced by therapeutic hypothermia. However, little is known about the concentrations of such drugs during rewarming. The aim of this study was to describe the serum concentrations of sedatives and analgesics during rewarming from therapeutic hypothermia. ⋯ Concentrations of remifentanil, propofol, and midazolam decreased during rewarming from therapeutic hypothermia when adjusting for rates of infusion. No changes were demonstrated for fentanyl.

ReviewNew oral anticoagulants: clinical indications, monitoring and treatment of acute bleeding complications.
New oral anticoagulants like the direct thrombin inhibitor, dabigatran (Pradaxa®), and factor Xa-inhibitors, rivaroxaban (Xarelto®) and apixaban (Eliquis®) are available for prophylaxis and treatment of thromboembolic disease. They are emerging alternatives to warfarin and provide equal or better clinical outcome together with reduced need for routine monitoring. Methods for measuring drug concentrations are available, although a correlation between plasma drug concentrations and the risk of bleeding has not been firmly established. ⋯ Further challenges regarding patients receiving new oral anticoagulants who presents with major bleeding or need for emergency surgery pose a unique problem. No established agents are clinically available to reverse the anticoagulant effect, although preclinical data report prothrombin complex concentrate as more efficient than fresh frozen plasma or other prohaemostatic agents. This review summaries current knowledge on approved new oral anticoagulants and discusses clinical aspects of monitoring, with particular focus on the management of the bleeding patient.
