Effect of Hydroxyethyl Starch vs Saline for Volume Replacement Therapy on Death or Postoperative Complications Among High-Risk Patients Undergoing Major Abdominal Surgery: The FLASH Randomized Clinical Trial.

Importance: It is not known if use of colloid solutions containing hydroxyethyl starch (HES) to correct for intravascular deficits in high-risk surgical patients is either effective or safe.

Objective: To evaluate the effect of HES 130/0.4 compared with 0.

Benefits of intraoperative analgesia guided by the Analgesia Nociception Index (ANI) in bariatric surgery: An unmatched case-control study.

Introduction: Analgesia Nociception Index (ANI) has been proposed for the evaluation of the nociception-antinociception balance in the perioperative period. In obese patients, where the management of analgesia may be rendered difficult by pharmacological changes, we hypothesised that the monitoring of analgesia with ANI would reduce intraoperative opioid consumption during bariatric surgery.

Methods: This monocentric, observational, unmatched case-control study aimed to compare perioperative data from obese subjects (body mass index ≥35kgm) during bariatric surgery with or without the use of ANI monitoring (ANI+ group versus ANI- group).

Bioelectrical impedance spectroscopy to estimate fluid balance in critically ill patients.

Fluid management is a crucial issue in intensive-care medicine. This study evaluated the feasibility and reproducibility of bioimpedance spectroscopy to measure body-water composition in critically ill patients, and compared fluid balance and daily changes in total body water (TBW) measured by bioimpedance. This observational study included 25 patients under mechanical ventilation.
