Why the study?
Does bispectral analysis (BIS) monitoring prevent intraoperative awareness in patients requiring sedation or general anesthesia?
Does bispectral analysis (BIS) monitoring prevent intraoperative awareness in patients requiring sedation or general anesthesia?
Bispectral analysis (BIS) offers a real-time measure of hypnosis levels to potentially prevent intraoperative awareness during anesthesia.
May support BIS for hypnosis monitoring; leaves open whether it prevents awareness without RCTs.
Despite advances in anesthetic technique and technology, intraoperative awareness continues to occur with alarming regularity. The psychological effects on patients and the medicolegal consequences to providers have created the need for a reliable monitor of the hypnotic component of anesthesia. A new technology known as bispectral analysis (BIS) has the potential to put an end to the devastating occurrence of intraoperative awareness, as well as improve the overall effectiveness of anesthetic delivery and the surgical experience. Applicable to almost any situation requiring sedation or general anesthesia, BIS's reliability is a real-time measure of hypnosis levels.
