ReviewWhy crystalloids will do the job in the operating room.
The current trend in anaesthesia is to choose crystalloid over colloid fluids for volume replacement in the operating room. Outcome-oriented studies and kinetic analyses have recently provided more insight into how crystalloid infusions should be managed. These fluids have a much better short-term effect on the plasma volume than previously believed. ⋯ Clinicians who do not want to prolong the length of the hospital stay by 1-2 days due to such problems may use colloid fluid selectively, but calculations show that the therapeutic window for colloids is quite narrow. Inflammation is likely to decrease the fluid efficiency of colloid fluids, while its effect on crystalloids is unclear. However, some recent evidence suggests that inflammation accelerates the turnover of crystalloid fluid as well.

ReviewThe role of abdominal compliance, the neglected parameter in critically ill patients - a consensus review of 16. Part 1: definitions and pathophysiology.
Over the last few decades, increasing attention has been paid to understanding the pathophysiology, aetiology, prognosis, and treatment of elevated intra-abdominal pressure (IAP) in trauma, surgical, and medical patients. However, there is presently a relatively poor understanding of intra-abdominal volume (IAV) and the relationship between IAV and IAP (i.e. abdominal compliance). Consensus definitions on Cab were discussed during the 5th World Congress on Abdominal Compartment Syndrome and a writing committee was formed to develop this article. ⋯ The Cab is one of the most neglected parameters in critically ill patients, although it plays a key role in understanding the deleterious effects of unadapted IAV on IAP and end-organ perfusion. The definitions presented herein will help to understand the key mechanisms in relation to Cab and clinical conditions and should be used for future clinical and basic science research. Specific measurement methods, guidelines and recommendations for clinical management of patients with low Cab are published in a separate review.

Randomized Controlled Trial Comparative StudyAssessment of the depth of anaesthesia during inhalational and intravenous induction of general anaesthesia.
Tracheal intubation is one of the strongest stimuli during general anaesthesia and may result in an insufficient depth of anaesthesia. The aim of the study was to compare the clinical evaluation of the depth of anaesthesia with an evaluation using entropy during inhalational and intravenous induction of general anaesthesia. ⋯ We found a discrepancy in the evaluation of the depth of anaesthesia based on clinical criteria compared with evaluations based on entropy values during both intravenous and inhalational induction of general anaesthesia.

Randomized Controlled TrialThe effect of bispectral index monitoring on anaesthetic requirements in target-controlled infusion for lumbar microdiscectomy.
Target-controlled infusion (TCI) is used to maintain the desired concentration of a hypnotic drug in the plasma and brain. However, pharmacodynamic variability can cause problems with maintaining the adequate level of anaesthesia. The bispectral index (BIS) is one of only a few parameters that allow an assessment of the depth of anaesthesia. In the present study, we attempted to determine the optimal dosages of drugs used for total intravenous anaesthesia with TCI based on BIS-guided monitoring of depth of anaesthesia. ⋯ BIS monitoring reduces the doses of opioids and hypnotics used during total intravenous anaesthesia by TCI.
