Fever represents a frequent and dangerous secondary insult for the injured brain and is often associated with worsened neurological outcomes. The identification of fever in the Neuro-Intensive Care Unit requires careful monitoring and rapid and effective treatment. The main objective of this article was to provide practical information regarding temperature monitoring, triggers for intervention and fever management in brain injured patients.

ReviewHyperoxia and oxidative stress in anesthesia and critical care medicine.
Oxygen administration is particularly relevant in patients undergoing surgery under general anesthesia and in those who suffer from acute or critical illness. Nevertheless, excess O2, or hyperoxia, is also known to be harmful. Toxicity arises from the enhanced formation of reactive oxygen species (ROS) that, exceeding the antioxidant defense, may generate oxidative stress. ⋯ To this purpose, we searched the PubMed database according to the following combination of key words: ("hyperoxia" OR "FiO2" OR "oxygen therapy") AND ("oxidative stress" OR "ROS" OR "RNS" OR "lipid peroxidation") AND ("anesthesia" OR "surgery" OR "intensive care"). We focused in the results from the past 20 years. Available evidence points toward a conservative monitoring and use of oxygen, unless there is solid proof of its efficacy.

Randomized Controlled Trial Comparative StudyUltrasound-guided radial artery cannulation using dynamic needle tip positioning versus conventional long-axis in-plane techniques in cardiac surgery patients: a randomized, controlled trial.
A novel ultrasound imaging technique, dynamic needle tip positioning (DNTP), enables continuous visualization of the needle tip during ultrasound-guided cannulation. The purpose of this study was to compare the rate of successful first-attempt radial artery cannulations between DNTP and the conventional long-axis in-plane (LAX-IP) technique. ⋯ The DNTP technique had a greater first-attempt success rate of radial artery cannulation compared to the conventional LAX-IP technique. Also, DNTP required significantly less time for cannulation and had fewer complications.
