Sleep in Critically III Chemically Paralyzed Patients Requiring Mechanical Ventilation: Causes

Patients were not quantitatively sleep deprived, but > 50% of sleep occurred during the daytime period, illustrating the disruption of nighttime sleep, alteration in normal circadian rhythm, and the importance of daytime sleep periods in preventing sleep depriva-tion. In contrast … Continue reading

Sleep in Critically III Chemically Paralyzed Patients Requiring Mechanical Ventilation: Discussion

Nine patients had temperatures > 38.5°C, and five patients had temperatures < 36.8°C. When temperature was compared to sleep stage, again there was no correlation. It was noted that three of five patients with temperatures < 36.8°C had the lowest … Continue reading

Sleep in Critically III Chemically Paralyzed Patients Requiring Mechanical Ventilation: Results

There was no statistical difference in delta activity for staging slow-wave sleep (SWS) between the two methods (p = 0.96). The Rechtschaffen and Kales scoring criteria resulted in 0%, 1%, and 5% reductions in staging SWS in the IS, CS, … Continue reading

Sleep in Critically III Chemically Paralyzed Patients Requiring Mechanical Ventilation: Drug Dosage Between Groups

Drug dosage was compared using both absolute dosage and dose per body weight. There was no statistical difference in body weight between groups (p = 0.06). However, there was an observed lower body weight in the IS group compared to … Continue reading

Sleep in Critically III Chemically Paralyzed Patients Requiring Mechanical Ventilation: Severity of Illness

A nonsignificant trend (p = 0.07) of increasing severity of illness (APACHE II), greatest in the CS/NMBA group relative to the IS group, was noted. The LIS was significantly higher in the CS and CS/NMBA groups (p < 0.001) than … Continue reading

Sleep in Critically III Chemically Paralyzed Patients Requiring Mechanical Ventilation: Patient Demographics

The NMBA administered was vecuronium by continuous infusion and titrated using the Dulin-Williams standard train-of-four protocol. The anxiolytic medication lorazepam was administered for sedation and titrated to a Ramsey score of 3 to 4. Morphine sulfate was administered intermittently or … Continue reading

Sleep in Critically III Chemically Paralyzed Patients Requiring Mechanical Ventilation: Polysomnography and Scoring

All subjects were monitored continuously for 24 h using polysomnography recorded on an eight-channel, portable EEG device (Neurotrac II model M1283A; Telefactor; Philadelphia, PA) interfaced with a monitor (model M1094B; Hewlett-Packard; Andover, MA). Gold cup electrode placement was performed according … Continue reading

Sleep in Critically III Chemically Paralyzed Patients Requiring Mechanical Ventilation: Study Site

The study was performed between June 1, 1999, and December 31, 2000, in the adult medical ICU at the University of California, Davis. The study protocol and consent form were approved by the Institutional Review Board of the Human Subjects … Continue reading

Sleep in Critically III Chemically Paralyzed Patients Requiring Mechanical Ventilation

Sleep deprivation is a well-documented problem among patients in the ICU and may impair physiologic and psychological well-being. Initial investigations using polysomnography reveal decreased total sleep time (TST), as well as abnormal sleep architecture with increased stage 1 and stage … Continue reading

A 44-Year-Old Woman With Polyarthritis, Fever, and Hilar Adenopathy: Recommendation

Lymph nodes in these patients have histologic changes typical for Wegener granulomatosus. Sixty-seven percent of Wegener granulomatosus patients will have musculoskeletal symptoms at some time during their disease course. These usually consist of arthralgias and myalgias. However, 28% of these … Continue reading
