Clinical TrialAEP-monitor/2 derived, composite auditory evoked potential index (AAI-1.6) and bispectral index as predictors of sevoflurane concentration in children.
Level of anesthesia may be predicted with the auditory evoked potential or with passive processed electroencephalogram (EEG) parameters. Some previous reports suggest the passive EEG does not reliably predict level of anesthesia in infants. The AAI-1.6 is a relatively new index derived from the AEP/2 monitor. It combines auditory evoked potentials and passive EEG parameters into a single index. This study aimed to assess the AAI-1.6 as a predictor of level of anesthesia in infants and children. ⋯ This preliminary study suggests AAI-1.6 is a poor predictor of sevoflurane concentration in infants and children.

Our aim was to describe the incidence of quality assurance events between overweight/obese and normal weight children. ⋯ Studies on perioperative aspects of childhood overweight and obesity are rare. Our report shows a high prevalence of overweight and obesity in this cohort of pediatric surgical patients. Certain perioperative morbidities are more common in overweight and obese than in normal weight children. There is a need for prospective studies of the impact of childhood overweight and obesity on anesthesia and surgical outcome.

ReviewInfluence of anesthesia on immune responses and its effect on vaccination in children: review of evidence.
Anesthesia and surgery exert immunomodulatory effects and some authors argue that they may exert additive or synergistic influences on vaccine efficacy and safety. Alternatively, inflammatory responses and fever elicited by vaccines may interfere with the postoperative course. There is a lack of consensus approach among anesthesiologists to the theoretical risk of anesthesia and vaccination. ⋯ These results are reinterpreted here in view of our current understanding of the immune mechanisms underlying vaccine efficacy and adverse events. We conclude that the immunomodulatory influence of anesthesia during elective surgery is both minor and transient (around 48 h) and that the current evidence does not provide any contraindication to the immunization of healthy children scheduled for elective surgery. However, respecting a minimal delay of 2 days (inactivated vaccines) or 14-21 days (live attenuated viral vaccines) between immunization and anesthesia may be useful to avoid the risk of misinterpretation of vaccine-driven adverse events as postoperative complications.

Randomized Controlled TrialLevel of sedation evaluation with Cerebral State Index and A-Line Arx in children undergoing diagnostic procedures.
Monitoring of anesthesia depth is difficult clinically, particularly in children. The aim of this study was to assess the correlation existing between CSI (Cerebral State Index), or AAI (A-line ARX) and a clinical sedation scale such as UMSS (University of Michigan Sedation Scale), during deep sedation with propofol in children undergoing diagnostic procedures. ⋯ Our study suggests that CSI and AAI may be two, real-time and objective tools to assess induction and emergence during propofol sedation in children undergoing EGDS and MRI.

Patient handover from surgery to intensive care: using Formula 1 pit-stop and aviation models to improve safety and quality.
We aimed to improve the quality and safety of handover of patients from surgery to intensive care using the analogy of a Formula 1 pit stop and expertise from aviation. ⋯ The introduction of the new handover protocol lead to improvements in all aspects of the handover. Expertise from other industries can be extrapolated to improve patient safety, and in particular, areas of medicine involving the handover of patients or information.
