SummaryModafinil is a new psychotropic compound with central α1, adrenergic-stimulant activity in animals. In the present study, its pharmacological activity in man was evaluated in the sleep-deprivation induced psychomotor and cognitive impairment paradigm. This was a double-blind placebo-controlled study involving 12 healthy volunteers. Standard psychomotor and memory tasks were used, including critical flicker fusion frequency determination (CFF), choice reaction time and short- and long-term memory evaluation. Results revealed a clear antagonism by modafinil of the psychomotor and cognitive impairment induced by sleep-deprivation in most tasks 6 h after drug administration, and marginal effects 18 h after. These results therefore support a psychostimulant activity of modafinil in man.

Objective: Determine whether dedicated family space changes family presence at night in the intensive care unit (ICU). Purpose: To measure family presence at night before and after moving to an ICU with in-room family space. Background: The safeguarding phenomenon families experience may lead to the desire to sit vigil at the bedside. Lack of dedicated family sleep space may exacerbate sleep deprivation for those who wish to be present at night. Sleep deprivation decreases cognition and capacity for decision-making. Traditionally, ICU rooms have not included dedicated family areas or sleep surfaces. National recommendations include designing new hospital ICU rooms with dedicated family space. It is not known if the built design changes family presence at night. Method: Family presence was measured for 30 nights pre- and postmove to a newly built ICU with dedicated family space. The policy for open flexible family presence remained the same before and after the move. Results: There was a statistically significant increase in proportion of occupied patient rooms with visitors following the move to the new ICU designed with family space (31% difference, x2= 5.675, 95% CI [5.74, 51.29], p = .0172). Conclusions: Families utilize the space when available. Further research is needed to quantify quality and quantity of family sleep and impact on decision-making and interactions with the care team. Sleep deprivation may decrease for families who would have remained in the unit without available family space and sleep surface.

SummaryA replication study of the effects of single-night sleep deprivation therapy was carried out as a preliminary to a controlled comparison with orthodox antidepressant measures. The results show that sleep deprivation therapy was acceptable to a majority of the patients studied, and was followed by an improvement in over half those who completed treatment. Adverse effects were minimal. The authors feel that further clinical and physiological study is warranted.

Abstract The present study analyzes the variations of heart rate (HR) and systolic and diastolic blood pressure (SBP and DBP) during 60 h of total sleep deprivation (TSD). All variables were evaluated every 2 h in a resting condition, during the performance of a vigilance task. Thirty healthy volunteers (15 men and 15 women) from 18 to 24 years old participated in the experiment. The analyses of variance (ANOVAS) with repeated measures showed some modifications of HR and SBP mean values mainly marked by circadian oscillations. The circadian oscillations had a smaller amplitude for SBP than for HR. HR showed a slight decrease on the second night of TSD and a slight increase on the third day of TSD. SBP decreased during the first 24 h of TSD and after that maintained its values without significant changes. DBP did not show any significant variations during TSD. In addition, there were no differences in function of gender for the TSD effect on the studied variables. All these statistically significant findings, however, seem to have no biological or clinical relevance. These aspects as well as the possible relationships between our results and activation or stress levels during TSD are discussed.
