The objective is to evaluate the sleep characteristics of the staff working in a pediatric intensive care unit (PICU). They were asked to complete an anonymous survey concerning the characteristics and quality of their sleep, as well as the impact of sleep disturbances on their work and social life, assessed by Functional Outcomes of Sleep Questionnaire (FOSQ)-10 questionnaire. The response rate was 84.6% (85% females): 17% were doctors, 57% nurses, 23% nursing assistants, and 3% porters. 83.8% of them worked on fix shifts and 16.2% did 24-h shifts. 39.8% of workers considered that they had a good sleep quality and 39.8% considered it to be poor or bad. The score was good in 18.2% of the staff and bad in 81.8%. Night shift workers showed significantly worse sleep quality on both the objective and subjective evaluation. There was a weak concordance (kappa 0.267; p = 0.004) between the perceived quality of sleep and the FOSQ-10 evaluation. Sleep disorders affected their emotional state (30.2% of workers) and relationships or social life (22.6%). In conclusion, this study finds that a high percentage of health professionals from PICU suffer from sleep disorders that affect their personal and social life. This negative impact is significantly higher in night shift workers. Many health workers are not aware of their bad sleep quality.

It has been suggested that neuromuscular blockade (NMB) affects the capacity of bispectral index (BIS) monitoring to measure consciousness in sedated children. Our aim was to analyse the impact of NMB on BIS values in critically ill children. We conducted a prospective observational study of children monitored with a BIS system that received a continuous infusion of vecuronium. We analysed data on clinical, diagnostic and haemodynamic variables, sedatives, analgesics, muscle relaxants, and BIS parameters. We compared BIS parameters before the use of a muscle relaxant, during its administration, before its discontinuation and for the 24hours following the end of the infusion. The analysis included 35 patients (median age, 30 months). The most common diagnosis was heart disease (85%). The most frequent indication for initiation of NMB was low cardiac output (45%), followed by adaptation to mechanical ventilation (20%). Neuromuscular blockade did not produce a significant change in BIS values. We found a decrease was observed in electromyography values at 6hours (34.9 ± 9.4 vs. 31.2 ± 7; P=.008) and 12hours after initiation of NMB (34.9 ± 9.4 vs. 28.6 ± 4.8; P=.006). We observed a small significant increase in BIS after discontinuation of NMB (from 42.7 ± 11 to 48.4 ± 14.5, P=.001), and 6 and 12hours later (51.3 ± 16.6; P=.015). There were no differences in the doses of sedatives or analgesics except for fentanyl, of which the dose was lowered after discontinuation of vecuronium. Continuous NMB produces small changes on BIS values that are not clinically significant and therefore does not interfere with BIS consciousness monitoring in critically ill children.

To analyze the sleep characteristics of the parents of children admitted to a pediatric intensive care unit (PICU), the possible risk factors and impact of sleep quality on their daily life activities. Parents of children admitted to PICU for at least 48 h filled in a survey. Demographic data, sleep characteristics before and during admission and its impact on daily life activities measured by the FOSQ-10 questionnaire, were collected. 100 surveys from parents of 53 children admitted to the PICU were collected. Most children (74%) were cardiac patients. 55% of them had had previous PICU admissions. 45% of parents lived in a different city. They spent a median of 14 h a day (IQR 12–16) at the hospital and 89.2% did not attend work. Parents had significantly worse subjective sleep quality (p = 0.001), less sleeping hours/day (p = 0.001), more difficulty falling asleep (p = 0.001) and more night arousals (p = 0.001) during PICU admission than before. 77% of parents also had a bad FOSQ-10 score. Perceived sleep quality and FOSQ-10 score had a good correlation (p = 0.00, Kappa 0.43). Significant risk factors were living in a different city (p = 0.03), programmed admissions (p = 0.001), previous PICU admissions (p = 0.001), prolonged PICU length of stay (p = 0.03) and longer distance from home (p = 0.03). Three quarters of the parents of children admitted to PICU suffer from sleep disorders, which negatively affects their personal lives. Perceived sleep quality had a good correlation with FOSQ-10 score. Institutional support is needed to optimize parents’ resting conditions during their child's hospitalization.
