    ABSTRACT: Intensive care unit (ICU) environmental factors such as noise and light have been cited as important causes of sleep deprivation in critically ill patients. Previous studies indicated that using earplugs and eye masks can improve REM sleep in healthy subjects in simulated ICU environment, and improve sleep quality in ICU patients. This study aimed to determine the effects of using earplugs and eye masks with relaxing background music on sleep, melatonin and cortisol levels in ICU patients. Fifty patients who underwent a scheduled cardiac surgery and were expected to stay at least 2 nights in Cardiac Surgical ICU (CSICU) were included. They were randomized to sleep with or without earplugs and eye masks combined with 30-minute relaxing music during the postoperative nights in CSICU. Urine was analyzed for nocturnal melatonin and cortisol levels. Subjective sleep quality was evaluated using the Chinese version of Richards-Campbell Sleep Questionnaire (a visual analog scale, ranging 0-100). Data from 45 patients (20 in intervention group, 25 in control group) were analyzed. Significant differences were found between groups in depth of sleep, falling asleep, awakenings, falling asleep again after awakening and overall sleep quality (P < 0.05). Perceived sleep quality was better in the intervention group. No group differences were found in urinary melatonin levels and cortisol levels for the night before surgery, and the first and second nights post-surgery (P > 0.05). The urinary melatonin levels of the first and second postoperative nights were significantly lower than those of the night before surgery (P = 0.01). The opposite pattern was seen with urinary cortisol levels (P = 0.00). This combination of non-pharmacological interventions is useful for promoting sleep in ICU adult patients; however, any influence on nocturnal melatonin levels and cortisol level may have been masked by several factors such as the timing of surgery, medication use and individual differences. Larger scale studies would be needed to examine the potential influences of these factors on biological markers and intervention efficacy on sleep.

    ABSTRACT: Evidence behind the recommendations for protein feeding during critical illness is weak. Mechanistic studies are needed to elucidate the effects of amino acid/protein supplementation on protein metabolism before larger clinical trials with higher protein feeding are initiated. Here we study the effects of parenteral amino acid supplementation (equivalent to 1 g/kg/day) over 3 h on whole body protein turnover in critically ill patients in the ICU during the first week after admission. Patients were studied at baseline during ongoing nutrition and during extra amino acid supplementation. If the patient was still in the ICU 2-4 days later, these measurements were repeated. Protein kinetics were measured using continuous stable isotope labeled phenylalanine and tyrosine infusions. Thirteen patients were studied on the first study occasion only and 7 were studied twice. Parenteral amino acid supplementation significantly improved protein balance on both occasions; from median -4 to +7 μmol phenylalanine/kg/h (P = 0.001) on the first study day and from median 0 to +12 μmol phenylalanine/kg/h (P = 0.018) on the second study day. The more positive protein balance was attributed to an increased protein synthesis rate which reached statistical significance during the first measurement (from 58 to 65 μmol phenylalanine/kg/h; n = 13; P = 0.007) but not during the second measurement (from 58 to 69 μmol phenylalanine/kg/h; n = 7; P = 0.09). Amino acid oxidation rates, estimated by phenylalanine hydroxylation, did not increase during the 3 h amino acid infusion. A positive correlation (r = 0.80; P < 0.0001)) between total amino acids/protein given to the patient and whole body protein balance was observed. Extra parenteral amino acids infused over a 3 hour period improved whole body protein balance and did not increase amino acid oxidation rates in critically ill patients during the early phase (first week) of critical illness.
