Analgesia and nociception can not be specifically monitored during general anesthesia. Movement of the patient or hemodynamic variations are usually considered as symptoms insufficient analgesia. The measure skin conductance (SC) allows an assessment peripheral sympathetic activity. analgesia-nociception index (ANI) provides evaluation parasympathetic activity based on heart rate variability. These two non-invasive monitors might allow a better perioperative nociception.Describe profiles SC...

Background This study was design to assess clinical agitation, electroencephalogram (EEG) and autonomic cardiovascular activity changes in children during induction of anesthesia with sevoflurane compared halothane using noninvasive recording EEG, heart rate, finger blood pressure. Methods Children aged 2-12 yr premedicated midazolam were randomly assigned one three techniques: 7% 100% O2 (group SevoRAPID); 2%, 4%, 6%, SevoINCR); or 1%, 3%, 3.5% 50% N2O-50% HaloN2O).

To investigate the differences between heart rate (HR) variability and pulse (PR) variability, short-term of finger wave ECG signals were studied in 10 children with a fixed ventricular pacemaker rhythm (80 beats/min). Ten healthy sinus served as reference population. Distal PR HR measured continuously using Finapres device an respectively. Power spectra for calculated both supine orthostatic positions. In paced subjects, exhibited characteristic respiratory peak, although flat. Similarly,...

In Brief BACKGROUND: this prospective study, we compared the relationship between propofol concentrations and bispectral index (BIS) in children versus young adults anesthetized with target-controlled infusion (TCI) of propofol. METHODS: Forty-five prepubertal subjects (children) 45 postpubertal (adults) were studied. All patients TCI propofol, based on Kataria et al.'s model for Schnider adults. data from BIS system continuously recorded using Rugloop software. Remifentanil was administered...

The aim of this study was to identify the best model describe pharmacokinetics and pharmacodynamics in prepubertal children therefore calculate corresponding pharmacodynamic parameters. In addition, confirm our method, a group postpubertal subjects also studied.Sixteen (9.5 yr, range 6-12) 13 adults (22 13-35) were included.

Background Sevoflurane has become the gold standard for inhalation induction in children. However children as adults, epileptiform electroencephalographic signs have been described under high concentrations of sevoflurane. The aim this study was to determine minimal alveolar concentration (MAC) sevoflurane associated with occurrence major (MES) 50% steady-state conditions. MAC MES (MAC MES) determined 100% oxygen and addition nitrous oxide or after injection alfentanil (ALFENTA). Methods...

In European countries, silage-free feeding is an ancient tradition and has a particularly positive reputation among consumers. the present study, we compared grass-based forages from same plot conserved as hay or silage fed fresh either on pasture indoors, evaluated differences in sensory properties of milk uncooked pressed cheese. All herbage first cut grassland dominated by perennial ryegrass was harvested day preserved silage. The regrowth used for strip grazing green indoors. Balanced...

The clinical benefits to be expected from intraoperative nociception monitors are currently under investigation. Among these devices, the Analgesia Nociception-Index (ANI) has shown promising results sevoflurane anesthesia. Our study investigated ANI-guided remifentanil administration propofol We hypothesized that ANI guidance would result in reduced consumption compared with standard management.

Rapid assessment of hemostasis during postpartum hemorrhage (PPH) is essential to allow characterization coagulopathy, estimate bleeding severity, and improve outcome. Point care (POC) coagulation monitors could be great interest for early diagnosis treatment disorders in PPH.Women with ongoing PPH >500 mL who clinically required an thromboelastography (TEG) were included. The primary aim this retrospective observational cohort study was assess the predictive accuracy TEG parameters...
