Background: Physical restraint is frequently used in intensive care units to prevent patients' life‐threatening removal of indwelling devices. In France, their use is poorly studied. Therefore, to evaluate the need for physical restraint, we have designed and implemented a decision support tool. Aims: Besides describing the prevalence of physical restraint use, this study aimed to assess whether the implementation of a nursing decision support tool had an impact on restraint use and to identify the factors associated with this use. Study Design: A large observational, multicentre study with a repeated one‐day point prevalence design was conducted. All adult patients hospitalized in intensive care units were eligible for this study. Two study periods were planned: before (control period) and after (intervention period) the deployment of the decision support tool and staff training. A multilevel model was performed to consider the centre effect. Results: During the control period, 786 patients were included, and 510 were in the intervention period. The prevalence of physical restraint was 28% (95% CI: 25.1%–31.4%) and 25% (95% CI: 21.5%–29.1%) respectively (χ2 = 1.35; p =.24). Restraint was applied by the nurse and/or nurse assistant in 96% of cases in both periods, mainly to wrists (89% vs. 83%, p =.14). The patient‐to‐nurse ratio was significantly lower in the intervention period (1:3.0 ± 1 vs. 1:2.7 ± 0.7, p <.001). In multivariable analysis, mechanical ventilation was associated with physical restraint (aOR [95% CI] = 6.0 [3.5–10.2]). Conclusion: The prevalence of physical restraint use in France was lower than expected. In our study, the decision support tool did not substantially impact physical restraint use. Hence, the decision support tool would deserve to be assessed in a randomized controlled trial. Relevance to Clinical Practice: The decision to physically restrain a patient could be protocolised and managed by critical care nurses. A regular evaluation of the level of sedation could allow the most deeply sedated patients to be exempted from physical restraint. [ABSTRACT FROM AUTHOR]

Background: A defining feature of prolonged critical illness is muscle wasting, leading to impaired recovery. Supplementation with a tailored blend of amino acids may bolster the innate gut defence, promote intestinal mucosa repair and limit muscle loss.Methods: This was a monocentric, randomized, double-blind, placebo-controlled study that included patients with sepsis or acute respiratory distress syndrome. Patients received a specific combination of five amino acids or placebo mixed with enteral feeding for 21 days. Markers of renal function, gut barrier structure and functionality were collected at baseline and 1, 2, 3 and 8 weeks after randomization. Muscle structure and function were assessed through MRI measurements of the anterior quadriceps volume and by twitch airway pressure. Data were compared between groups relative to the baseline.Results: Thirty-five critically ill patients were randomized. The amino acid blend did not impair urine output, blood creatinine levels or creatinine clearance. Plasma citrulline levels increased significantly along the treatment period in the amino acid group (difference in means [95% CI] 5.86 [1.72; 10.00] nmol/mL P = 0.007). Alanine aminotransferase and alkaline phosphatase concentrations were lower in the amino acid group than in the placebo group at one week (ratio of means 0.5 [0.29; 0.86] (P = 0.015) and 0.73 [0.57; 0.94] (P = 0.015), respectively). Twitch airway pressure and volume of the anterior quadriceps were greater in the amino acid group than in the placebo group 3 weeks after randomization (difference in means 10.6 [0.99; 20.20] cmH20 (P = 0.035) and 3.12 [0.5; 5.73] cm3/kg (P = 0.022), respectively).Conclusions: Amino acid supplementation increased plasma citrulline levels, reduced alanine aminotransferase and alkaline phosphatase levels, and improved twitch airway pressure and anterior quadriceps volume.

Background: Intravenous (IV) milrinone, in combination with induced hypertension, has been proposed as a treatment option for cerebral vasospasm after aneurysmal subarachnoid hemorrhage (aSAH). However, data on its safety and efficacy are scarce. Methods: This was a controlled observational study conducted in an academic hospital with prospectively and retrospectively collected data. Consecutive patients with cerebral vasospasm following aSAH and treated with both IV milrinone (0.5 µg/kg/min−1, as part of a strict protocol) and induced hypertension were compared with a historical control group receiving hypertension alone. Multivariable analyses aimed at minimizing potential biases. We assessed (1) 6-month functional disability (defined as a score between 2 and 6 on the modified Rankin Scale) and vasospasm-related brain infarction, (2) the rate of first-line or rescue endovascular angioplasty for vasospasm, and (3) immediate tolerance to IV milrinone. Results: Ninety-four patients were included (41 and 53 in the IV milrinone and the control group, respectively). IV milrinone infusion was independently associated with a lower likelihood of 6-month functional disability (adjusted odds ratio [aOR] = 0.28, 95% confidence interval [CI] = 0.10–0.77]) and vasospasm-related brain infarction (aOR = 0.19, 95% CI 0.04–0.94). Endovascular angioplasty was less frequent in the IV milrinone group (6 [15%] vs. 28 [53%] patients, p = 0.0001, aOR = 0.12, 95% CI 0.04–0.38). IV milrinone (median duration of infusion, 5 [2–8] days) was prematurely discontinued owing to poor tolerance in 12 patients, mostly (n = 10) for "non/hardly-attained induced hypertension" (mean arterial blood pressure < 100 mmHg despite 1.5 µg/kg/min−1 of norepinephrine). However, this event was similarly observed in IV milrinone and control patients (n = 10 [24%] vs. n = 11 [21%], respectively, p = 0.68). IV milrinone was associated with a higher incidence of polyuria (IV milrinone patients had creatinine clearance of 191 [153–238] ml/min−1) and hyponatremia or hypokalemia, whereas arrhythmia, myocardial ischemia, and thrombocytopenia were infrequent. Conclusions: Despite its premature discontinuation in 29% of patients as a result of its poor tolerance, IV milrinone was associated with a lower rate of endovascular angioplasty and a positive impact on long-term neurological and radiological outcomes. These preliminary findings encourage the conduction of confirmatory randomized trials. [ABSTRACT FROM AUTHOR]

Pragmatically, because moderate-to-severe angiographic vasospasm, even if asymptomatic, was the trigger for the initiation of IV milrinone, ensuring that angiographic vasospasm resolved (at least partly) was key in the weaning process from IV milrinone in the Milrispasm study. Indeed, after 2 days of milrinone IV infusion, if vasospasm was stable or even worse compared with its aspect on the previous CT angiography, affirming that IV milrinone failed in vasospasm reversal is challenging because its natural course could have been a significantly more severe vasospasm at that time.
