Gender effect on recovery time following isoflurane administration while using a bispectral index monitor .

Gender effect on recovery time following isoflurane administration while using a bispectral index monitor /. Article. Introduction The bispectral index monitoring system (BIS) was introduced in the United States in 1994 and approved by the FDA in 1996 with the objective of measuring the level of consciousness through an algorithm analysis of the (EEG) during general anesthesia. This novelty allowed both the surgeon and the anesthesiologist to have a more objective perception of anesthesia depth.

Bispectral index and traumatic brain injury . The bispectral index (BIS) is an algorithm developed by Aspect Medical Systems that measures EEG changes following administration of anesthetic agents (Halliburton and McCarthy, 2000).

The use of BIS monitoring to guide anesthetic administration and monitor patient status is a clinical decision. BIS Index values are the result of two particular innovations: bispectral analysis and the BIS™ algorithm. It is the responsibility of each clinician to make clinical practice decisions that are in the best interest of the patient. Today, the BIS Index remains the most validated form of consciousness or brain function monitoring used within the clinical context of anesthesia and sedation care. BIS Index values are the result of two particular innovations: bispectral analysis and the BIS™ algorithm

Bispectral index (BIS) is one of several technologies used to monitor . Bispectral index monitor indicating a nearly isoelectric pattern of hic activity.

Bispectral index (BIS) is one of several technologies used to monitor depth of anesthesia. BIS monitors are used to supplement Guedel's classification system for determining depth of anesthesia. The US Food and Drug Administration (FDA) cleared BIS monitoring in 1996 for assessing the hypnotic effects of general anesthetics and sedatives A reduction in awareness provides a public health benefit, in that BIS technology can now provide anesthestists with a way to reduce this often debilitating, yet preventable medical error".

To assess if titration of sevoflurane using the bispectral index (BIS) monitor improves the early and intermediate recovery in geriatric outpatients undergoing brief urologic procedures under general anesthesia without muscle relaxants. After a standardized induction with propofol and fentanyl, a laryngeal mask airway was inserted and sevoflurane was administered in combination with 60% nitrous oxide in oxygen for maintenance of anesthesia in spontaneously breathing outpatients.

Using logistic regression, the indices were compared both individually and in combination as to the power of distinguishing awake (at pre-induction) from asleep (at tube insertion) states. BIS had the best predictive power, with a sensitivity of 9. %, specificity 9. %, positive predictive value 9. % and negative predictive value 9. %.

It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A878124. The abstract provided by the Pentagon follows: Gender has been implicated as affecting outcomes of anesthesia (Gan et al., 1999; Myles, McLeod, Hunt, & Fletcher, 2001). The literature is replete with studies indicating significant gender differences in analgesic requirements. In contrast, literature comparing gender differences in recovery times following general anesthesia is sparse. Review of the literature found little published research considering recovery variations among genders using volatile inhaled agents; in addition, most of the studies referring to this potential were retrospective in nature. Recovery time differences have been reported between genders during propofol, alfentanil, and nitrous oxide anesthesia (Gan et al., 1999), with women recovering faster than men. Additionally, a prospective cohort study found that women emerged faster than men from general anesthesia but had a slower rate of return to preoperative health status (Myles et al., 2001). The purpose of this study was to further investigate gender differences in recovery times from general anesthesia using isoflurane and the Bispectral Index monitor (BIS). A convenience sample of 30 men and 22 women (ASA classification: I or II) was enrolled. Subjects received a standardized anesthetic of isoflurane and fentanyl. Depth of anesthesia was assessed using clinical parameters and the bispectral index monitor (BIS) monitor. Wake-up time was measured by the number of minutes it took for subjects to meet both of two endpoints (opening of eyes and hand grasp-and-release to command). An average time of 5.6 minutes for women versus 6.87 minutes for men was found.
