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.

Randomized Controlled Trial Clinical TrialContinuous positive airway pressure/pressure support pre-oxygenation of morbidly obese patients.
Morbidly obese patients are more prone to desaturation of arterial blood during apnea with induction of anesthesia than are non-obese. This study aimed to assess the effect of low-pressure continuous positive airway pressure (CPAP) with pressure support ventilation (PSV) during pre-oxygenation on partial oxygen pressure in arterial blood (PaO2 ) immediately after tracheal intubation (post-intubation PaO2). ⋯ In morbidly obese patients, low-pressure CPAP combined with low-pressure PSV during pre-oxygenation resulted in better oxygenation, compared with neutral-pressure breathing, and prevented desaturation episodes.

Randomized Controlled Trial Comparative StudyPost-operative atelectasis - a randomised trial investigating a ventilatory strategy and low oxygen fraction during recovery.
Atelectasis is common during and after general anaesthesia. We hypothesized that a ventilation strategy with a combination of 1) continuous positive airway pressure (CPAP) or positive end-expiratory pressure (PEEP) and 2) a reduced end-expiratory oxygen concentration during recovery would reduce post-operative atelectasis. ⋯ Inducing anaesthesia with CPAP/PEEP and FIO2 1.0 and deliberately reducing FIO2 during recovery before removal of the LMA did not reduce post-operative atelectasis compared with FIO2 1.0 before removal of the LMA.

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.
