To better understand the involvement of the progressive increase in low-frequency bands in the intrinsic maintenance of the alert state, we assessed the effects of time on the processes expressed in broad-band event-related potentials (ERPs) at play during a test of sustained attention. In this test, the fixed sustained attention to response task (SART) paradigm, a predictable series of single digits are presented (1-9) and subjects are required to make a response to each number (go trials) with the exception of the number 3 (no-go trial)...

OBJECTIVE: This research aims to identify the impact of text messaging on simulated driving performance. BACKGROUND: In the past decade, a number of on-road, epidemiological, and simulator-based studies reported the negative impact of talking on a cell phone on driving behavior. However, the impact of text messaging on simulated driving performance is still not fully understood. METHOD: Forty participants engaged in both a single task (driving) and a dual task (driving and text messaging) in a high-fidelity driving simulator...

BACKGROUND: During routine cases, anesthesia providers may divert their attention away from direct patient care to read clinical (e.g., medical records) and/or nonclinical materials. The authors sought to ascertain the incidence of intraoperative reading and measure its effects on clinicians' workload and vigilance. METHODS: In 172 selected general anesthetic cases in an academic medical center, a trained observer categorized the anesthesia provider's activities into 37 possible tasks...

BACKGROUND: Obesity-hypoventilation syndrome (OHS) is efficiently treated by noninvasive ventilation (NIV). Sleep respiratory disturbances, reduced ventilatory drive, and excessive daytime sleepiness (EDS) are commonly reported, but their relationships remain unclear. OBJECTIVES: To characterize sleep breathing disorders encountered in patients with OHS, to compare low and normal CO(2) responders in terms of sleep abnormalities, subjective and objective measures of EDS, and to measure the changes induced by NIV on these parameters...

An observational tool was developed to record distraction and interruption in the operating theatre during surgery. Observed events were assigned to pre-defined categories and rated in relation to the level of team involvement - the sum of which was treated as a measure of intra-operative interference. Many events (0.29 +/- 0.02 per min) were observed and rated in 50 general operations sampled from a single operating theatre. The rating of individual events (r(s) = 0.65) and of cases (r(s) = 0.89) correlated between independent observers...

RANDOMIZED CONTROLLED TRIAL

INTRODUCTION: When used to counteract the effects of sleep deprivation, multiple doses of caffeine are typically ingested across an extended period of time. The goal of this study was to determine the optimal dose of caffeine for sustaining performance during sleep loss with administration of multiple doses. METHODS: There were 48 subjects (28 men, 20 women) who were randomly assigned to 1 of 4 groups (placebo, 50, 100, or 200 mg caffeine). After an overnight 8-h sleep period, subjects were required to remain awake for the ensuing 29 h...

UNLABELLED: In this study, we sought to examine several measures of anesthesia provider workload during different phases of anesthesia care and during teaching and nonteaching cases. Clinical work was assessed in real-time during 24 general anesthetics performed by consenting anesthesia providers. Workload was measured using physiological (provider heart rate), psychological (self-assessment and observer rating), and procedural (response latency to an alarm light and workload density) techniques...

This research examined the effects of hands-free cell phone conversations on simulated driving. The authors found that these conversations impaired driver's reactions to vehicles braking in front of them. The authors assessed whether this impairment could be attributed to a withdrawal of attention from the visual scene, yielding a form of inattention blindness. Cell phone conversations impaired explicit recognition memory for roadside billboards. Eye-tracking data indicated that this was due to reduced attention to foveal information...

BACKGROUND: Administering anesthesia is a complex task in which either human or equipment failure can have disastrous consequences. An improved understanding of the nature of the anesthesiologist's job could provide a more rational basis for improvements in provider training as well as the design of anesthesia equipment. The objective of this study was to develop a set of techniques to evaluate anesthesiologist performance and to determine what information could be obtained from performing real-time task assessment and workload analysis tests in the operating room...
