ReviewMonitoring tissue oxygenation by near infrared spectroscopy (NIRS): background and current applications.
Conventional cardiovascular monitoring may not detect tissue hypoxia, and conventional cardiovascular support aiming at global hemodynamics may not restore tissue oxygenation. NIRS offers non-invasive online monitoring of tissue oxygenation in a wide range of clinical scenarios. NIRS monitoring is commonly used to measure cerebral oxygenation (rSO(2)), e.g. during cardiac surgery. ⋯ Therefore, measuring and obtaining adequate tissue oxygenation may prevent (postoperative) complications and may thus be cost-effective. NIRS monitoring may also be used to detect tissue hypoxia in (prehospital) emergency settings, where it has prognostic significance and enables monitoring of therapeutic interventions, particularly in patients with trauma. However, optimal therapeutic agents and strategies for augmenting tissue oxygenation have yet to be determined.

Anesthesiology is a stressful medical profession. While anesthesia in particular has become safer for the patient in the last decades, anesthesiology as a profession represents a medical field in which the professionals are permanently tense. The various reasons for this situation include the fact that anesthesiology is a team profession that requires perfect cooperation with other specialists. ⋯ This reality created the need to look for remedies; some authors recommend a long list of measures to be taken in order to prevent or reduce the magnitude of professional stress. This list includes a continuous self-care attitude, consisting of having a balanced professional and personal life; adequate sleep; avoiding drugs, obesity, and "workaholic" behavior; as well as better use of leisure. Finally, more studies are needed to find out which preventive means may potentially reduce the risk of professional stress among anesthesiologists.

In the present review we will describe and discuss the physiological and technological background necessary in understanding the dynamic parameters of fluid responsiveness and how they relate to recent softwares and algorithms' applications. We will also discuss the potential clinical applications of these parameters in the management of patients under general anesthesia and mechanical ventilation along with the potential improvements in the computational algorithms.

ReviewAnesthesia information management systems: a review of functionality and installation considerations.
The functionality and rate of implementation of Anesthesia Information Management Systems (AIMS) has markedly risen over the past decade. These systems have now become much more than the generic automated record keepers, originally proposed and developed in the 1980s. AIMS have now become complex integrated systems, which have been shown to improve patient care and, in some cases, the financial performance of a department. Although the underlying technology has improved greatly over the past 5 years, the process of selecting and completing an AIMS installation still presents a number of challenges, and must be approached carefully in order to maximize the benefits provided by these systems.

ReviewAcid-base chemistry of plasma: consolidation of the traditional and modern approaches from a mathematical and clinical perspective.
Debate still exists as to whether the Stewart (modern) or traditional model of acid-base chemistry is best in assessing the acid-base status of critically ill patients. Recent studies have compared various parameters from the modern and traditional approaches, assessing the clinical usefulness of parameters such as base excess, anion gap, corrected anion gap, strong ion difference and strong ion gap. To compare the clinical usefulness of these parameters, and hence the different approaches, requires a clear understanding of their meaning; a task only possible through understanding the mathematical basis of the approaches. The objective of this paper is to provide this understanding, limiting the mathematics to a necessary minimum. ⋯ Although different in their concepts, the traditional and modern approaches based on mathematical models can be seen as complementary giving, in principle, the same information about the acid-base status of plasma.
