Randomized Controlled Trial
Hepatocellular integrity after parenteral nutrition: comparison of a fish-oil-containing lipid emulsion with an olive-soybean oil-based lipid emulsion.
Parenteral nutrition including lipids might be associated with liver disease. The cause leading to parenteral nutrition-related liver dysfunction remains largely unknown but is likely to be multifactorial. The study was performed to assess the effects of a lipid emulsion based on soybean oil, medium-chain triglycerides, olive and fish oil (SMOFlipid20%) compared with a lipid emulsion based on olive and soybean oil on hepatic integrity. ⋯ Hepatic integrity was well retained with the administration of SMOFlipid whereas in patients receiving a lipid emulsion based on olive and soybean oil liver enzymes were elevated indicating a lower liver tolerability.

Randomized Controlled Trial Comparative Study
Ondansetron added to lidocaine for intravenous regional anaesthesia.
The aim of this study was to evaluate the effect of ondansetron when added to lidocaine for intravenous regional anaesthesia (IVRA). ⋯ Addition of ondansetron to lidocaine may improve the quality of IVRA and prolong postoperative analgesia in patients undergoing hand surgery.

Randomized Controlled Trial Comparative Study
Could a single standardized ultrasonographic measurement of antral area be of interest for assessing gastric contents? A preliminary report.
The aim of this preliminary study performed on volunteers was to assess whether a standardized ultrasonographic measurement of the gastric antral cross-sectional area in a single section of the stomach could discriminate between gastric contents after 12 h fasting (fasting stomach) and gastric contents 2 h after ingestion of nonclear liquids or a solid meal. ⋯ Results of this preliminary study should be corroborated in further trials. However, one can suppose that ultrasonographic measurement of the antral cross-section area could be of interest for the diagnosis of preoperative gastric vacuity.

Different minimally invasive haemodynamic monitoring techniques are commercially available today and in the recent years they have proved adequate in replacing the pulmonary artery catheter under certain clinical conditions. Moreover, several of these techniques provide additional new parameters primarily related to preload assessment. Therefore, in order to be used in daily clinical practice, the diversity of minimally invasive haemodynamic monitoring requires knowledge of the different techniques, the different parameters provided by the devices and their clinical validity. The aim of the present article is to review the most widely used minimally invasive cardiac output monitoring techniques; emphasize the new parameters available for preload assessment;and propose a modular stepwise monitoring concept.
