Brain temperature was continuously measured in 58 patients after severe head injury and compared to rectal temperature, intracranial pressure, cerebral blood flow, and outcome after 3 months. The temperature difference between brain and rectal temperature was also calculated. Mild hypothermia (34-36 degrees C) was also used to treat uncontrollable(More)
INTRODUCTION This prospective randomized clinical study investigated the efficacy and safety of 7.2% hypertonic saline hydroxyethyl starch 200/0.5 (7.2% NaCl/HES 200/0.5) in comparison with 15% mannitol in the treatment of increased intracranial pressure (ICP). METHODS Forty neurosurgical patients at risk of increased ICP were randomized to receive either(More)
We studied brain temperature and the effect of mild hypothermia in 58 patients after severe head injury (SHI). Brain tissue oxygen tension (ptiO2), carbon dioxide tension (ptiCO2), tissuie pH (pHti) and temperature (T.br) were measured using a multiparameter probe. Microdialysis was performed to measure glucose, lactate, glutamate, and aspartate in the(More)
INTRODUCTION This randomised, open-label, observational, multicentre, parallel group study assessed the safety and efficacy of analgesia-based sedation using remifentanil in the neuro-intensive care unit. METHODS Patients aged 18-80 years admitted to the intensive care unit within the previous 24 hours, with acute brain injury or after neurosurgery,(More)
Early impaired cerebral blood flow (CBF) after severe head injury (SHI) leads to poor brain tissue oxygen delivery and lactate accumulation. The purpose of this investigation was to elucidate the relationship between CBF, local dialysate lactate (lact(md)) and dialysate glucose (gluc(md)), and brain tissue oxygen levels (PtiO2) under arterial normoxia. The(More)
OBJECTIVE The aim of the present study was to examine the impact of moderate and profound hyperventilation on regional cerebral blood flow (rCBF), oxygenation and metabolism. MATERIALS AND METHODS Twelve anesthetized pigs were subjected to moderate (mHV) and profound (pHV) hyperventilation (target arterial pO(2): 30 and 20 mmHg, respectively) for 30 min(More)
The use of volatile anesthetics in the intensive care unit (ICU) has only been possible at great cost with the use of commercially available anesthesia systems. A new anesthetic-conserving device (AnaConDa) now facilitates, from a technical viewpoint, the routine use of volatile anesthetics in intensive care patients as part of prolonged sedation, using ICU(More)
Local brain tissue oxygenation (p(ti)O2) and global cerebrovenous hemoglobin saturation (SjO2) are increasingly used to continuously monitor patients after severe head injury (SHI). In patients, simultaneous local and global oxygen measurements of these types have shown different results regarding the comparability of the findings during changes in CPP and(More)
A prospective, randomized, double-blind study was performed in 62 patients (ASA Classes I and II) treated with either 0.15 or 0.25 mg/kg cisatracurium or 0.15 mg/kg vecuronium administered as a rapid bolus. We wished to determine whether the muscle relaxants caused cutaneous, systemic, or chemical evidence of histamine release. Six minutes after induction(More)
Objectives: The aim of this study was to compare the sensitivity of a newly applied transoesophageal ultrasonic Doppler sensor for detection of air with the traditional precordial ultrasonic Doppler sensor in clinical use. Methods: We studied 16 patients undergoing neurosurgical procedures in a sitting position. Two ultrasonic Doppler devices were compared(More)
