Dexmedetomidine, a highly selective alpha2-adrenoceptor agonist used for short-term sedation of mechanically ventilated patients, has minimal effect on ventilation.This study compared the respiratory dexmedetomidine to that remifentanil. The authors measured and responses six healthy male volunteers during (1) stepwise target-controlled infusion remifentanil, (2) dexmedetomidine, (3) pseudonatural sleep session.Compared with baseline, remifentanil infusions resulted in depression as...
The goal of this study was to evaluate whether preoperative pressure pain sensitivity testing is predictive postoperative surgical pain.Female subjects undergoing lower abdominal gynecologic surgery were studied. A algometer used preoperatively determine the threshold and tolerance. visual analog scale (VAS) assess pain. State-Trait Anxiety Inventory patients' anxiety. Subjects received intravenous patient-controlled analgesia for control. tolerance compared with VAS score morphine...
Dexmedetomidine is a highly selective alpha2-adrenoceptor agonist used for short-term sedation of mechanically ventilated patients. The analgesic profile dexmedetomidine has not been fully characterized in humans.This study was designed to compare the responses six healthy male volunteers during stepwise target-controlled infusions remifentanil and dexmedetomidine. A computer-controlled thermode deliver painful heat stimuli volar side forearms subjects. Six sequential 5-s (ranging from 41...
Summary Pulse oximeters may delay displaying the correct oxygen saturation during onset of hypoxia. We investigated desaturation response times pulse oximeter sensors (forehead, ear and finger) vasoconstriction due to mild hypothermia vasodilation caused by glyceryl trinitrate. Ten healthy male volunteers were given three hypoxic challenges 3 min duration under differing experimental conditions. Mild increased mean time finger from 130 215 s. Glyceryl trinitrate partly offset this effect...
Background Midazolam is used commonly for sedation in the surgical intensive care unit. A suboptimal dosing regimen may lead to relative overdosing, which could result delayed extubation and increased cost. This multicenter trial characterized midazolam pharmacodynamics patients recovering from coronary artery bypass grafting. Methods Three centers enrolled 90 undergoing All received sufentanil via target-controlled infusion. After surgery, was titrated a Ramsay score of 5 2 h then decreased...
Background Midazolam is commonly used for short-term postoperative sedation of patients undergoing cardiac surgery. The purpose this multicenter study was to characterize the pharmacokinetics and intersubject variability midazolam in coronary artery bypass grafting. Methods With institutional review board approval, 90 consenting grafting were enrolled at three centers. All subjects received sufentanil via target-controlled infusions. After operation, titrated maintain deep least 2 h. It then...
Résumé Vu le manque de mesures in situ, il est difficile d'estimer volume d'eau stocké sous forme neige sur Mont Liban et encore plus prévoir avec quelle rapidité ce sera disponible. C'est là que la télédétection peut aider modélisation hydrologique. Ainsi, serait possible mettre à jour distribution spatiale l'équivalent en eau sèche partir d'images RADARSAT-1. L'approche a été testée l'hiver 2001. Les résultats obtenus portent croire l'algorithme susceptible s'appliquer au couvert neigeux...
Abstract The assessment of the spatial and temporal distribution water resources in Mediterranean region is crucial for better management available resources. In Lebanon particular, snow a parameter supply. However, few research works were performed until now to study this potential resource because difficulties inherent measurement volume stored by snow. Remote sensing, more specifically radar imaging, favourite tool investigating equivalent. This aims assess synthetic aperture (SAR)...
