View clinical trials related to Propofol Overdose.
Filter by:In the world, 230 million surgeries are performed per year and a significant part is performed in patients over 65 years of age. These patients are more labile, especially from the neurocognitive point of view with a high risk to develop neurocognitive complications, such as postoperative delirium. Recent studies have linked this type of complication with an overdose of general anesthetics during surgery. For this reason, in recent years, the use of brain function monitors during the intraoperative period has been recommended to adapt the dosage of the drugs to each patient and thus to avoid overdosing of general anesthetics. However, to date, the available monitors that process the electroencephalographic signal are not able to adequately discriminate gradual changes in anesthetic depth. Also, no systematic studies have been performed that analyze changes that occur in the electroencephalogram (EEG) signal secondary to increases in complications from general anesthetics. Thus, the investigators design this study with the main aim to determine the changes in electroencephalographic patterns induced by a stepped increase of propofol until the burst suppression is reached.
Newborns admitted to an intensive care unit often require artificial ventilation. For that purpose an endotracheal tube needs to be placed into the trachea, a procedure named endotracheal intubation. The newborns need to be sedated to keep them comfortable, to stop moving and to relax in order to enable the success of the procedure. For this sedation an anesthetic agent named propofol is often used. The used dose of propofol has not been properly studied and as a consequence patients are under- or over -sedated and propofol leads to side effects such as hypotension. The current study aims to find the most appropriate dose of propofol for newborns of different gestational ages and of different post-natal ages. We will use propofol in different doses and after each 5 included patients per age group we will analyze whether the dose needs to be increased or decreased. The effect of the propofol will be extensively monitored and we will study the level of sedation, the quality of intubation, the stability of the patient en the occurrence of side effects. At the end we aim to have appropriate guidelines for propofol doses in newborns of all ages.
