Hinkelbein, J. et al. | European Society of Anaesthesiology and European Board of Anaesthesiology guidelines for procedural sedation and analgesia in adults | European Journal of Anaesthesiology
Procedural sedation and analgesia (PSA) has become a widespread practice given the increasing demand to relieve anxiety, discomfort and pain during invasive diagnostic and therapeutic procedures.
The European Society of Anaesthesiology (ESA) and the European Board of Anaesthesiology have created a taskforce of experts that has been assigned to create an evidence-based guideline and, whenever the evidence was weak, a consensus amongst experts on: the evaluation of adult patients undergoing PSA, the role and competences required for the clinicians to safely perform PSA, the commonly used drugs for PSA, the adverse events that PSA can lead to, the minimum monitoring requirements and post-procedure discharge criteria.
A search of the literature from 2003 to 2016 was performed by a professional librarian and the retrieved articles were analysed to allow a critical appraisal according to the Grading of Recommendations Assessment, Development and Evaluation method.
These guidelines contain recommendations on PSA in the adult population. It does not address sedation performed in the ICU or in children and it does not aim to provide a legal statement on how PSA should be performed and by whom. The National Societies of Anaesthesiology and Ministries of Health should use this evidence-based document to help decision-making on how PSA should be performed in their countries.

Background: To reduce head movement during resting state functional magnetic resonance imaging, post-coma patients with disorders of consciousness (DOC) are frequently sedated with propofol. However, little is known about the effects of this sedation on the brain connectivity patterns in the damaged brain essential for differential diagnosis. In this study, we aimed to assess these effects.
Conclusions: Our findings indicate that connectivity decreases associated with propofol sedation, involving the thalamus and insula, are relatively small compared with those already caused by DOC-associated structural brain injury. Nonetheless, given the known importance of the thalamus in brain arousal, its disruption could well reflect the diminished movement obtained in these patients. However, more research is needed on this topic to fully address the research question.

Mobile interactive tools have been found to be effective to reduce child anxiety at parental separation in the operating theatre. The authors’ aim in this study was to compare the effects of midazolam (a sedative used regularly before anaesthesia) in premedication with age-appropriate game apps (on an iPad tablet) on children aged 4-10 years during and after ambulatory (day) surgery. Anxiety was assessed both in children and in parents.
Children were randomly allocated to one of the two groups (MDZ [midazolam-54 children] or TAB [iPad — 58 children]). Patients in group MDZ received midazolam 0.3mg/kg orally or rectally, or, in group TAB, were given an electronic tablet (iPAD) 20 min before anaesthesia. Child anxiety (using m-YPAS scale) was measured by 2 independent psychologists at four time points: 1) at arrival at hospital 2) at separation from the parents 3) during induction and 4) in the post anaesthesia care unit (PACU). Parental (using STAI score) anxiety was measured at the same time points except during induction as they were not present at that point. Anaesthetic nurses ranked from 0 (not satisfied) to 10 (highly satisfied) the quality of induction of anaesthesia.
Then, 30 minutes after the child received their last dose of nalbuphine anaesthestic or 45 min after arrival in the PACU, the children were transferred to the ambulatory surgery ward where parental anxiety (STAI 3) and children anxiety (m-YPAS 4) were again evaluated for the final time. In addition, parents’ satisfaction with the anaesthesia procedure was rated from 0 to 10. Postoperative behaviour changes were assessed with the Post Hospital Behaviour Questionnaire (PHBQ).
The researchers found both parental and child anxiety levels to be similar in both groups, with a similar pattern of evolution. Both parents and nurses found anaesthesia more satisfying in the iPad group.
