Multicenter StudyFirst closed-loop goal directed fluid therapy during surgery: A pilot study.
Intraoperative haemodynamic optimization based on fluid management and stroke volume optimization (Goal Directed Fluid Therapy [GDFT]) can improve patients' postoperative outcome. We have described a closed-loop fluid management system based on stroke volume variation and stroke volume monitoring. The goal of this system is to apply GDFT protocols automatically. After conducting simulation, engineering, and animal studies the present report describes the first use of this system in the clinical setting. ⋯ Intraoperative GDFT delivered by closed-loop system under anaesthesiologist guidance allowed to obtain targeted objectives in 91% of surgery time. This approach may provide a way to ensure consistent high-quality delivery of fluid administration and compliance with perioperative goal directed therapy.

Case ReportsFactor V and VIII combined deficiency: Clinical perioperative management for tonsillectomy in a child.
Combined factors V (FV) and VIII (FVIII) deficiency is a rarely seen hereditary coagulation disease. Experience of its management in surgery with a high-risk of bleeding is rare. The interest of this case report is to propose a strategy of perioperative management for such a deficit, but also to recall that a careful preoperative anesthetic evaluation with questioning and physical examination permits to detect unsuspected coagulation disorders and to schedule the preventive treatment. ⋯ Fresh frozen plasma and tranexamic acid were administered during the first 9 postoperative days. A local bleeding occurred at 8 days (scab coming off) and required systematically a surgical hemostasis and an intensification of the therapeutic protocol. Recombinant plasmatic factor VIII was administered for 7 days together with a daily perfusion of fresh frozen plasma for a total treatment period of 14 days.

Review[Nuclear magnetic resonance based metabolic phenotyping for patient evaluations in operating rooms and intensive care units.]
Metabolic phenotyping consists in the identification of subtle and coordinated metabolic variations associated with various pathophysiological stimuli. Different analytical methods, such as nuclear magnetic resonance, allow the simultaneous quantification of a large number of metabolites. Statistical analyses of these spectra thus lead to the discrimination between samples and the identification of a metabolic phenotype corresponding to the effect under study. ⋯ Metabolic phenotyping could be useful in anaesthesiology and intensive care medicine for the evaluation, monitoring or diagnosis of life-threatening situations, to optimise patient managements. This review introduces the physical and statistical fundamentals of NMR-based metabolic phenotyping, describes the work already achieved by this approach in anaesthesiology and intensive care medicine. Finally, potential areas of interest are discussed for the perioperative and intensive management of patients, from newborns to adults.
