315 results about "Propofol" patented technology

Propofol, marketed as Diprivan among other names, is a short-acting medication that results in a decreased level of consciousness and lack of memory for events. Its uses include the starting and maintenance of general anesthesia, sedation for mechanically ventilated adults, and procedural sedation. It is also used for status epilepticus if other medications have not worked. It is given by injection into a vein. Maximum effect takes about two minutes to occur and it typically lasts five to ten minutes.

Combining multiple qeeg features to estimate drug-independent sedation level using machine learning

The present disclosure describes systems and methods of estimating sedation level of a patient using machine learning. For example, the integration of multiple QEEG features into a single sedation level estimation system using machine learning could result in a significant improvement in the predictability of the levels of sedation, independent of the sedative drug used. The present disclosure advantageously allows for the incorporation of large numbers of QEEG features and machine learning into the next-generation monitors of sedation level. Different QEEG features may be selected for different sedation drugs, such as propofol, sevoflurane and dexmedetomidine groups. The sedation level estimation system can maintain a high performance for detecting MOAA / S, independent of the drug used.

Formulations containing propofol and a sulfoalkyl ether cyclodextrin

An injectable formulation of a sedative hypnotic drug, such as the anesthetic drug propofol, that is pharmaceutically stable and demonstrates a reduced incidence of pain upon injection. The formulation of the present invention employs a sulfoalkyl ether cyclodextrin solubilizing and complexing excipient, such as CAPTISOL® cyclodextrin (sulfobutyl ether β-cyclodextrin) to form a true aqueous solution and not a suspension. This formulation minimizes the allergic response and microbial contamination issues typically associated with propofol parenteral formulations. The present formulation may also reduce pain on injection as compared to the known emulsion type propofol formulations. The liquid formulation can be sterile filtered unlike emulsion-type formulations of sedative hypnotics. The liquid formulation can be lyophilized or otherwise dried to yield a solid formulation.
