Anesthesia Medications Automatically Delivered During Surgery
A team of French anesthesiologists has developed an automatic delivery system of propofol and remifentanil, which they recently tested in a multi-center trial involving 196 surgical patients. The researchers reported in Anesthesia & Analgesia that the system, which uses a Bispectral Index (BIS) monitor as a guide, performed better than manual administration:
We have developed a proportional-integral-derivative controller allowing the closed-loop coadministration of propofol and remifentanil, guided by a Bispectral Index (BIS) monitor, during induction and maintenance of general anesthesia. The controller was compared with manual target-controlled infusion.
The controller allows the automated delivery of propofol and remifentanil and maintains BIS values in predetermined boundaries during general anesthesia better than manual administration.

In a development that may have you undergo your next medical procedure the old-fashioned way, two researchers from the University of California-San Francisco and the University of Oslo are reporting that inhaled anesthetics significantly contribute to the destruction of the ozone layer and add to the overall global warming gas content in the atmosphere.
