Meta AnalysisThe efficacy of NMDA receptor antagonists for preventing remifentanil-induced increase in postoperative pain and analgesic requirement: a meta-analysis.
Meta-analysis was performed to evaluate the preventive effects of N-methyl-D-aspartate (NMDA) receptor antagonists on remifentanil-induced increase in postoperative pain and analgesic requirement in patients. ⋯ These data do not support the use of NMDA receptor antagonists, ketamine and magnesium sulfate to prevent the development of remifentanil-induced postoperative hyperalgesia and tolerance.

Review Meta AnalysisPediatric delirium in the pediatric intensive care unit: a systematic review and an update on key issues and research questions.
There was a dearth in awareness and knowledge regarding pediatric delirium (PD) at the pediatric intensive care unit (PICU). The aim of this study is to highlight the most recent and up-to-date findings of current literature -by means of a systematic review (SR) method-, and to present the key issues and research questions. ⋯ There still is a dearth of literature on PD, with also a variable level of evidence (1b - 5), especially in relation to critical illness. To be able to further clarify PD in the PICU, additional research questions are provided for future research.

Review Meta AnalysisSteroids in severe pneumonia: a literature review.
Despite more than sixty years of scientific medical research, severe pneumonia, either community-acquired or nosocomial, remains a leading cause of death regardless of the patients' immunity state. The clinical introduction of new and more potent antibiotic molecules and the continuous development of efficient respiratory assistance devices may not be able to radically improve the clinical outcome of pneumonia. Adjunctive therapies based on the physiopathological mechanisms of lung damage in severe pneumonia have been strongly advocated, and corticosteroids, which present many properties that theoretically interfere with these pathways, have been widely used, with conflicting results. ⋯ In severe pneumonia, preclinical data, including cytokine level detection and animal studies, have shown encouraging results, although the clinical data is controversial. Moreover, large randomized controlled trials have not been conducted to determine steroid side effects and the risk of immunosuppression-induced superinfections. The benefits of steroid use in patients with severe pneumonia have not been proven by current literature, but ongoing investigations of anti-inflammatory molecules probably represent the key point of severe infection management in the near future.

Review Meta AnalysisContinuous intravenous infusion of ketamine for maintenance sedation.
Ketamine HCl is a rapidly acting general anesthetic with sedative and analgesic properties that has been reported to have favorable effects on the cardiovascular and pulmonary systems. The goal of this review is to determine the hemodynamic and pulmonary effects of continuous intravenous (IV) ketamine infusion in mechanically ventilated patients, and to determine whether sufficient evidence exists to support its use as an agent for maintenance anesthesia. PubMed/Medline, EMBASE, and Index Medicus databases as well as relevant bibliographies were searched. ⋯ It also improves respiratory rate and oxygenation, and does not promote respiratory depression. Additionally, ketamine does not result in significant perturbations in blood pressure, heart rate, or vascular resistance. Ketamine may be a safe and effective tool for maintenance sedation of mechanically ventilated patients, however a large prospective clinical trial is warranted.

Review Meta AnalysisThe preventive role of higher PEEP in treating severely hypoxemic ARDS.
This review summarizes knowledge and evidence on the use of positive end-expiratory pressure (PEEP) in patients with severely hypoxemic acute respiratory distress syndrome (ARDS). More specifically, it documents the current evidence on the effects of higher PEEP in preventing (or attenuating) lung damage during the ventilatory management of patients with severely hypoxemic ARDS. No established threshold has been set to define severely hypoxemic ARDS and higher PEEP. ⋯ Higher PEEP should be used with caution in patients less severe hypoxemic (acute lung injury). To deliver optimal PEEP to those ARDS patients with the highest lung recruitability, this technique should be monitored at the bedside. Alternative methods are under investigation as part of a decremental PEEP trial.
