Filter by:The intercostobrachial nerve underlies many anatomical variations. For surgery of the upper arm the axilla is usually not anaesthetized by a brachial plexus block, which therefore needs to be completed by an intercostobrachial nerve block. The optimal access for an ultrasound guided block of the intercostobrachial nerve is not yet known. The investigators compare a proximal and a more distal approach to the nerve referred to onset time, sensory blocked area and duration.
This trial is a part of the project: 'A novel technique for reliable, precise and safe postoperative pain management' (project no. 65-2014-3). The purpose of the trial is to investigate the effects of changing peri-neural infusion rates of ropivacaine 0.2% on the duration of nerve block. Intervention: Two intervention-days. Each day a peri-neural infusion of a fixed volume of ropivacaine 0.2% is to be infused in one of five infusion rates, using a peri-neural catheter. Intervention day 1: Focus on the common peroneal nerve. Intervention day 2: Focus on the sciatic nerve.
In patients under general anesthesia, episodes of hypotension are often treated with phenylephrine. The effect of phenylephrine is conventionally attributed to afterload increase. The aim of the study is to describe the time course of the effects of phenylephrine on the cardiac preload and cardiac output, and to evaluate whether phenylephrine, as an exclusive alpha-mimetic, could be beneficial for preload optimisation.
General anaesthesia (GA) is, according to many definitions, the greatest gift presented to the medical art (S. B. Nuland). One of the aims of GA is to achieve the optimal depth of anaesthesia and rapid emergence from general anaesthesia. In order to achieve this goal, it is necessary to observe the clinical condition of the patient, and at the same time monitor the patient's overall condition. With the currently available options of GA management (e.g. use of intravenous anaesthetics, strong analgesics and modern volatile anaesthetics, in combination with various methods of topical anaesthesia) the importance of methods measuring the depth of GA increases. The depth of GA may be defined as a continuous progressive decreasing of the central nervous system, together with a decreased reactivity to stimuli. In the course of GA, perioperative awareness is detected in 0.1-0.2% of cases. Awakening during a surgical procedure may result in significant psychological complications (e.g. post-traumatic stress disorder), and the patient may suffer from a serious long-time disorder.
The purpose of this study is to compare three communications during peripheral intravenous catheterization and measure pain patient: one hypnotic, confusion (HYPNOSIS), an other with negative connotation (NOCEBO) and at least with neutral connotation (NEUTRAL).
Transoesophageal ultrasound examination before and after prone position.
What is the optimal maintenance dose of remifentanil to ensure apnoea, during breath hold episodes in children having cardiac MR imaging with general anaesthesia?
Patients need information for perioperative period and internet may be an interesting alternative.This study analysed by questionaire what does patient look on internet: information of perioperative period and specifically for anesthesia. Questionaire (8 questions) are distributed to the patient before surgery and after they were prepared by surgeon. Population : adult (> 18 y), no emergency procedure.The mean question is the use of internet for anesthesia information.
To study the 30-day morbidity and mortality after neonatal anaesthesia, and predictive factors that can be responsible for poor outcome.
