1. Cerebral perfusion in cardiac surgery : with special reference to circulatory arrest during profound hypothermia
Abstract : Thirty-nine pediatric and 82 adult patients were studied during cardiac surgery with cardio pulmonary bypass (CPB) performed with moderate hypothermia or with deep hypothermia and circulatory arrest (DHCA) with or-without retrograde cerebral perfusion (RCP). Cerebral blood flow (CBF) was estimated from Doppler measurements of the blood velocity in the middle cerebral artery (MCAv). READ MORE

2. High frequency jet ventilation (HFJV) in clinical practice
Abstract : Background: Surgery often requires general anaesthesia. During general anaesthesia, a ventilator is often used to secure the breathing of the patient. This is preferably done by mimicking normal ventilation. READ MORE

3. Background aEEG/EEG measures in very preterm infants : Relation to physiology and outcome
Abstract : The overall aim of this thesis was to characterize single-channel aEEG/EEG, recorded during the first postnatal days in preterm infants, in relation to brain function and two-year outcome. Study I investigated if aEEG/EEG was associated with neonatal brain injury, inflammation and outcome in 16 very preterm (VPT) infants. READ MORE

4. Measures to prevent microembolization in cardiac surgery and during angiography with special reference to carbon dioxide
Abstract : Background: Cardiovascular interventions including open heart surgery using cardiopulmonary bypass (CPB) and coronary angiography may introduce air and particulate arterial embolism that may lead to tissue lesions of the brain and other organs. Aims: To assess: if CO2-insufflation of an empty CPB circuit decreases number of gaseous emboli in the prime compared with a conventional CPB circuit, which holds air before fluid priming (Study I); the efficacy of a new mini-diffuser device for CO2 de-airing in a minimally invasive open cardiothoracic wound cavity model and in patients undergoing minimally invasive open aortic valve surgery (Study II); if an extra separate venous reservoir abolishes CO2-insufflation induced hypercapnia and retains sweep gas flow of the oxygenator constant during open heart surgery (Study III); if there is a difference in the incidence of cerebral microemboli when using either the femoral or the radial approach during coronary angiography (Study IV).

5. Minimal volume ventilation in lung injury : With special reference to apnea and buffer treatment
Abstract : A fairly large portion of patients receiving surgical or intensive care will need mechanical ventilation at some point. The potential ventilator-induced lung injury (VILI) is thus of interest. One of the main causal factors in VILI is the cyclic energy shifts, i.e. READ MORE
