Filter by:Unhealthy alcohol drinking is negatively influencing health of people and costing a large number of annual finance via "secondhand" effects. Additionally, unhealthy alcohol use covers a spectrum that is associated with varying degrees of risk to health. The investigators hypothesized that unhealthy alcohol drinking resulted in significant increase in anesthetic requirement during general anesthesia. This investigation would clarify the association between unhealthy alcohol use and the intraoperative consumption of anesthetics, and provide clinical evidence for preoperative assessment with respect to the alcohol drinking habit.
Medications used to put people to sleep during surgical procedures also cause changes in the body's ability to control its temperature. These changes can make a person's temperature drop below normal. To minimize this drop in body temperature, different types of body warming products are used during surgery. This study is designed to compare the the temperatures of people under general anesthesia after 60 minutes of warming with each product. The study hypothesis is that the people warmed with the Dynatherm Medical vitalHEAT vH2 System will decrease less in the first 60 minutes of warming time than people warmed with the Arizant Bair Hugger System.
The association of general anesthesia and of thoracic epidural anesthesia is used in thoracic surgery with a demonstrated benefit on the risk of postoperative respiratory complications. The objective of the study is to analyze the influence of thoracic epidural administration of chirocaine (5 mg/ml) on the administration of anesthetic agents (propofol and remifentanil), these drugs being administrated using a closed-loop system with the Bispectral Index as the controller. Two groups of patients are compared: - one group will receive general anesthesia and thoracic epidural administration of saline. Chirocaine will be administered before patient's awakening, - one group will receive general anesthesia and thoracic epidural administration of chirocaine (5 mg/ml). In both groups, the closed-loop system ensures that le depth of anesthesia is similar in both groups.
This study will evaluate the accuracy of several thermometers and temperature changes during surgery and immediately after surgery.
The purpose of this study is to learn more about an Entropy monitor that the anesthesiologist will be using.
This study should compare the propofol concentration in breathing gas and in plasma (before and) after lung passage. Propofol concentrations in breathing gas are continuously measured by a sensor. For comparison a discontinuous method is used. Neurophysiologic parameters for determination of depth of anesthesia are compared to the continuous measured propofol concentration in breathing gas. Study hypothesis: continuous measured propofol concentration in breathing gas correlates to propofol concentration in plasma and depth of anaesthesia.
The purpose of the study is to assess whether spinal anesthesia is or not superior to the standard general anesthesia for fit patients undergoing laparoscopic cholecystectomy.
Surgery performed during general anesthesia induces a stress effect on the body. Our plan is to identify population at risk of hyperglycemia during perioperative period.
The ability of Mid Latency Auditory Evoked Potentials for a routine monitoring of sensory suppression should be evaluated during a wide spectrum of clinically common forms general anesthesia.
