Filter by:There are many different types of intravenous anesthetics used in gastroscopy, but each type of drug has its advantages and disadvantages,remimazolam is a novel ultra-short-acting benzodiazepine with rapid onset and recovery, low circulatory depression, and rapid reversal of sedation by flumazenil,remimazolam may be another relatively ideal sedative-hypnotic option for anesthesiologists and gastrointestinal endoscopists. The purpose of this study was to explore whether remimazolam combined with propofol is safer and more effective than remimazolam alone or propofol alone in gastrointestinal endoscopy.
Hypotension during anesthesia is associated with serious organ failure and death. The most critical period for intraoperative hypotension is the postinduction period during which, one-third of intraoperative hypotension occurs. Post-induction hypotension has many contributing factors; however, it is closely related to anesthetic drugs. Therefore, manipulation of induction agents makes post-induction hypotension likely preventable. Emergency laparotomy is a critical category of surgery whose patients are usually hemodynamically compromised and prone to post-induction hypotension; furthermore, these patients are usually at high risk of aspiration of gastric contents and require rapid-sequence induction of anesthesia and optimum intubating conditions. Thus, induction of anesthesia for emergency laparotomy requires meticulous balance between achievement of adequate hypnosis and maintenance of stable blood pressure. Propofol is the commonest hypnotic agent worldwide. However, it is usually associated with hypotension especially in compromised patients. Ketamine produces dissociative anesthesia and sympathetic stimulation which provides more stable hemodynamic profile; however, ketamine is not widely used as a routine hypnotic because it produces psychomimetic effects such as delirium and emergence agitation. Nevertheless, ketamine still has a role in induction of anesthesia in patients with shock and during procedural sedation. Ketamine is also used as analgesic adjuvant during general anesthesia. Propofol/ketamine admixture (ketofol) was introduced in anesthetic practice aiming to compensate the side effects of the two drugs and to provide, consequently, the desired balance between adequate hypnosis and hemodynamic stability. Ketofol is currently used with a diversity in the ratio between the two drugs which ranges between 1:1 and 1:10 between ketamine and propofol. Despite its frequent use in sedation and complete anesthesia, most of the available literature for comparisons of different ketofol mixtures was restricted to procedural sedation whose results are not applicable in induction of anesthesia due to the different desirable level of hypnosis and recovery. Therefore, the best combination of the two components of ketofol for induction of anesthesia is unknown
The experience for many children who need to undergo anesthesia induction by breathing anesthetic vapors in the operating room is frightening to the child. We have developed a computer-based game system that uses breathing-in and breathing-out as a game controller. We believe that the immersive game experience will encourage breathing patterns ideal for anesthetic induction while providing fun and diversion for the child, lessening or eliminating the fear that typically accompanies breathing anesthetics. The purpose of the study is to determine whether diversion and breathing encouragement offered by a game and this device
This is a multi-center, randomized, double-blind, propofol-controlled phase III clinical trial. The primary objective is to compare the efficacy and safety between propofol and HSK3486 for the induction of general anesthesia in elective surgery subjects, so as to provide reference for marketing registration of HSK3486.
The purpose of this study is to determine if a slow stepwise propofol TCI induction with Marsh model (Ke0 0.26), allows for an accurate estimation of the effect site concentration required for maintenance of the general anesthesia, with propofol and remifentanil, in adult populations older and younger than 65 years of age.
