The main purpose of this study was to verify the feasibility of brain temperature mapping with high-spatial- and reduced-spectral-resolution magnetic resonance spectroscopic imaging (MRSI). A secondary goal was to determine the temperature coefficient of water chemical shift in the brain with and without internal spectral reference. The accuracy of the(More)
PURPOSE To estimate absolute brain temperature using proton MR spectroscopy ((1)H-MRS) and mean brain-body temperature difference of healthy human volunteers. MATERIALS AND METHODS Chemical shift difference between temperature-dependent water spectral line position and temperature-stable metabolite spectral reference was used for the estimations of(More)
Among drowning victims who are younger than 20 years, 3–68% are children aged 0–5 years.1 We present two cases f children who suffered cardiac arrest and hypothermia after rowning. The first case was a two-year-old boy who fell in a wimming pool. He was found lifeless after about 10min. Cariopulmonary resuscitation (CPR) was initiated 5min later by the(More)
BACKGROUND Treatment of palmar hyperhidrosis with botulinum toxin (BTX) requires effective anesthesia, but previous methods have not provided enough pain relief or have resulted in a prolonged impaired hand function. OBJECTIVE This is a study of bilateral forearm intravenous regional anesthesia using prilocaine for BTX treatment of palmar hyperhidrosis.(More)
Intranasal cooling can be used to initiate therapeutic hypothermia. However, direct measurement of brain temperature is difficult and the intra-cerebral distribution of temperature changes with cooling is unknown. The purpose of this study was to measure the brain temperature of human volunteers subjected to intranasal cooling using non-invasive magnetic(More)
AIM To study haemodynamic effects and changes in intravascular volume during hypothermia treatment, induced by ice-cold fluids and maintained by ice-packs followed by rewarming in patients after resuscitation from cardiac arrest. MATERIALS AND METHODS In 24 patients following successful restoration of spontaneous circulation (ROSC), hypothermia was(More)
BACKGROUND Intranasal balloon catheters circulated with cold saline have previously been used for the induction and maintenance of selective brain cooling in pigs with normal circulation. In the present study, we investigated the feasibility of therapeutic hypothermia initiation, maintenance and rewarming using such intranasal balloon catheters with or(More)
TO THE EDITOR: Middle cerebral artery blood velocity (MCAVmean) is reduced up to 30% in humans following a passive increase in internal temperature of 1–1.5°C (1). If the diameter of the MCA remains unchanged during heat stress, reductions in MCAVmean are proportional to reductions in cerebral blood flow. In support of selective brain cooling in(More)
OBJECTIVE The aim of the study was to investigate the frequency and outcome of prolonged intensive care unit (ICU) length of stay (LOS) after abdominal aortic aneurysm (AAA) repair in the endovascular era. METHODS All patients operated on for AAA between 1999 and 2013 at Uppsala University hospital were identified. Data were retrieved from the Swedish(More)
Decrease of the human brain temperature was induced by intranasal cooling. The main purpose of this study was to compare the two magnetic resonance methods for monitoring brain temperature changes during cooling: phase-difference and magnetic resonance spectroscopic imaging (MRSI) with high spatial resolution. Ten healthy volunteers were measured. Selective(More)
