Review Meta AnalysisDrugs for anaesthesia and analgesia in the preterm infant.
There is largely an absence of validated evidence-based therapies in term- and preterm newborn infants, due to a lack of pharmacological clinical trials. As a consequence, the drugs and doses used in clinical practice are extrapolated from dose-ranging trials performed in older patients. Drugs administered to the preterm infant are invariably off-label. The aim of this current review is to identify commonly used anesthetic and analgesic agents in this patient population, assess the existing evidence base, in terms of safety, efficacy, pharmacokinetics and pharmacodynamics, current indications and doses. ⋯ Preterm infants are characterized by remarkable metabolic and developmental differences when compared with adults. It is not possible to derive guidelines or clinical recommendations based on the existing evidence.

The standard conditions of critical illness (including sepsis, acute respiratory distress syndrome, and multiorgan failure) cause enormous global mortality and a growing economic burden. Increasing evidence suggests that critical illness may be associated with loss of commensal microbes and overgrowth of potentially pathogenic and inflammatory bacteria. ⋯ Although the precise mechanisms of microbiome-directed treatments such as prebiotics, probiotics, and fecal microbiota transplantation remain to be determined, they can be utilized in the Intensive Care Unit (ICU) setting. The current review aims to offer intensivists an evidenced-based approach on what we currently know about the role of the microbiome in critical illness and how the microbiome could be targeted in the clinical practice to improve ICU-related outcomes.

A new pressure guided management tool for epidural space detection: feasibility assessment in a clinical scenario.
The detection of epidural space is usually performed by the technique of loss of resistance (LOR) without technological support, although there are few commercial options. In this work, we aimed to assess the feasibility of a new, non-invasive, mechatronic system for LOR detection in clinical settings. The system allows monitoring the pressure exerted on the syringe plunger by the clinician during the puncture. The LOR is related to the mentioned pressure. ⋯ The proposed mechatronic system successfully detected the LOR in the large part of cases using the configurations characterized by the best trade-off between system sensitivity and range of measurements. A non-significant increment of the procedure time is related to the use of the system.

Observational StudyInfluence of mechanical ventilation and loading modifications on left ventricular global longitudinal strain in patients undergoing general anesthesia. A pilot study.
The modifications of left ventricular systolic function assessed with global longitudinal strain (GLS) after general anesthesia and invasive mechanical ventilation are poorly described. ⋯ Systolic function assessed with GLS is impaired after general anesthesia and invasive mechanical ventilation in patients without cardiovascular co-morbidities but remains within normal range.
