- Red hair has been linked to altered sensitivity to pain, analgesics, and hypnotics. This alteration may be impacted by variants in the melanocortin-1 receptor (MC1R) gene, which are mainly found in redheads. The aim of this narrative review was to explore and present the current state of knowledge on red hair and its plausible associations with altered responsiveness to pain, analgesics, and hypnotics. Structured searches in the PubMed, CINAHL Complete, and Scopus electronic databases were conducted. Evidence suggests that women with red hair have an increased sensitivity to pain. Conversely, data also indicate a higher pain tolerance in homozygous carriers of MC1R variant alleles. Varied responses to analgesia have been reported, with both increased analgesic responsiveness in homozygous carriers of MC1R variant alleles and less analgesia in redheads. Data indicate an increased need for hypnotics in redheads. However, failed attempts to find statistical associations between red hair and altered responsiveness to hypnotics are also evident. Even though there seems to be an association between red hair and an altered responsiveness to pain, analgesics, and/or hypnotics, the results of this narrative review are inconclusive. Further research studies with larger populations and MC1R testing are needed.

- Purpose: Smart glasses are a kind of wearable technology that gives users sustained, hands-free access to data and can transmit and receive information wirelessly. Earlier studies have suggested that smart glasses have the potential to improve patient safety in anesthesia care. Research regarding health care professionals' views of the potential use of smart glasses in anesthesia care is limited. The purpose of this study was to describe anesthesia health care professionals' views of smart glasses before clinical use. Design: A qualitative descriptive study. Methods: Data were collected from focus group interviews and analyzed using thematic content analysis. Findings: Three categories of participants' views of smart glasses were created during the analysis: views of integrating smart glasses in clinical setting; views of customized functionality of smart glasses; and views of being a user of smart glasses. One theme, striving for situational control, was identified in the analysis. Conclusions: Smart glasses were seen as a tool that can impact and improve access to patient-related information, and aid health care professionals in their struggle to gain situational control during anesthesia care. These are factors related to increased patient safety. (c) 2020 American Society of PeriAnesthesia Nurses. Published by Elsevier Inc.

- Introduction: Trauma stress and neuro-inflammation caused by surgery/anaesthesia releases cytokines. This study analysed impact of Auditory Evoked Potential Index (AAI) depth-of-anaesthesia titration on the early plasma IL-6 release after eye surgery under general anaesthesia.Method: This is a subgroup analysis of a prospective randomized study on the effect of auditory evoked potential guided anaesthesia for eye surgery. Plasma IL-6 levels taken before, 5 and 24 h after end of surgery from 450 patients undergoing elective ophthalmic surgery under desflurane anaesthesia were analysed. Minimal mental state examination (MMSE) was also tested at 24-h.Results: IL-6 increased significantly at both 5 and further at 24 h after surgery (3.2, 4.5 and 5.1 base-line, 5 and 24-h respectively), the IL-6 increase showed different patterns between the 2 groups; IL-6 was significantly increased in the control group of patients between preoperative baseline and 24 h after surgery (p = 0.008) also between 5 h and 24 h, (p = 0.006) after surgery while the AAI-group had only minor non-significant changes. The 18 patients that showed a 24-h MMSE score less than 25 had a significant higher 24-h IL-6 compared to the 390 patients with a MMSE score > 24 (p = 0.002).Conclusion: The IL-6 increase after surgery was less pronounced in patients where anaesthesia was titrated by AAI compared to anaesthesia adjusted on clinical signs only. IL-6 were also found to be higher in patients with a MMSE < 25 at 24-h. Further studies are warranted evaluating the role of depth of anaesthesia monitoring on the risk for early cognitive impairment and neuro-inflammation.

- The aim of this study was to evaluate the role of depth of anesthesia on POCD after major ENT surgery and to assess changes in postoperative inflammatory markers in patients undergoing major ENT surgery. Thirty two patients aged 40 to 94 yrs, scheduled for surgery under general anesthesia were randomly assigned to one of two groups. In group A (AEP group) depth of anesthesia (DOA) was measured with auditory evoked potential (AEP). In the control group (group C) DOA was monitored according to clinical signs. Cognitive function was evaluated using Mini-Mental State Examination (MMSE), Confusion Assessment Method (CAM) and Cognitive Failure Questionnaire (CFQ). Inflammatory markers were measured before and after anesthesia. Perioperative requirements for desflurane and fentanyl were significantly lower in group A. On the first postoperative day MMSE changes indicating POCD were noted in 1 patient in group A and 7 patients in group C (P<0.03). One month follow up did not show any difference between the groups regarding POCD. Our study indicates that AEP-guided anesthesia allows dose reduction of anesthetic agents including opioids leading to better cardiovascular stability and less early POCD. Anesthesia depth did not influence the inflammatory response to surgery.

- Cognitive side-effects such as emergence agitation (EA), postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) are not infrequently complicating the postoperative care especially in elderly and fragile patients. The aim of the present survey was to gain insight regarding concern and interest in prevention and treatment strategies for postoperative delirium and dysfunction, and the use of EEG-based depth-of-anaesthesia monitoring possibly reducing the risk for cognitive side effects among anaesthesia personnel.METHODS: A web-based validated questionnaire was sent to all Swedish anaesthesiologists and nurse anaesthetists during summer 2013. The questionnaire consisted of 3 sections, subjective preferences, routines and practices related to the perioperative handling of EA, POD, POCD.RESULTS: The response rate was 52%. Cardiovascular/pulmonary risks where assessed as importance by 98, 97% of responders while 69% considered the risk of neurocognitive side-effects important. When asked explicitly around cognitive side-effects 89%, 37% and 44% assessed awareness, POC and POD respectively of importance. EEG-based depth-of-anaesthesia monitors were used in 50% of hospitals. The responders were not convinced about the benefits of such monitors even in at-risk patients. Structured protocols for the management of postoperative cognitive side-effects were available only in few hospitals.CONCLUSION: Swedish anaesthesia personnel are concerned about the risk of postoperative cognitive side-effects but are more concerned about cardiovascular/pulmonary risks, pain, PONV and the rare event of awareness. Most respondents were not convinced about the use of depth-of-anaesthesia monitors. There is a need to improve knowledge around risk factors, prevention and management of postoperative cognitive side effects.

Tidskriftsartikel (refereegranskat)abstract
- Emergence agitation following anesthesia in children is not uncommon. It is, although generally self-limiting, associated with both patient and parents distress. We conducted a national survey around the management of behavioral and neurocognitive disturbances after surgery/anesthesia including a case scenario about a child at risk for emergence reaction. Premedication with clonidine or midazolam would have been used 58 and 37% of responders respectively. A propofol based anesthesia was the most common anesthetic technique, however sevoflurane or desflurane was an option for 45 and 8% of responders. Before awakening 65% would have administered an opioid, 48% a low-dose of propofol and 25% clonidine. Sign or symptoms of behavioral disturbance was not assessed by standardize assessment tools.A majority of Swedish anesthesia personnel would undertake some preventive action when handling a child at risk for an emergence reaction, the preventive measure differed and it seems as there is an obvious room for further improvements.

- Previous studies have attempted to determine the depth of anaesthesia with different anaesthetic agents using electroencephalogram (EEG) measurements with variable success. Measuring depth of anaesthesia is confounded by the complexity of the EEG and the fact that different agents create different pattens. A narrative review was undertaken to examine the available research evidence on the effect and reliability of spectral edge frequency (SEF) for assessing the depth of anaesthesia in adult patients under general anaesthesia. A systematic search of the PubMed®, Scopus®, CINAHL and Cochrane databases identified six randomized controlled trials and five observational studies. The findings of these studies suggest that SEF varies according to the anaesthetic drugs used. Remifentanil and age are two factors that can affect SEF, while other opioids and benzodiazepine (administered separately) seem to have no effect. No patients experienced intraoperative awareness. However, this does not indicate that SEF can provide full protection against it and the number of articles in which intraoperative awareness was studied was too small to afford any certainty. None of the studies demonstrated a reliable SEF interval associated with adequate general anaesthesia. SEF must be adapted to the anaesthetic drug used, the patient's age and state while under general anaesthesia.

- BACKGROUND: Opioid-based treatment is used to manage stress responses during surgery and postoperative pain. However, opioids have both acute and long-term side-effects, calling for opioid-free anaesthetic strategies. This meta-analysis compares adverse events, postoperative recovery, discharge time from post-anaesthesia care unit, and postoperative pain, nausea, vomiting, and opioid consumption between strict opioid-free with opioid-based general anaesthesia.METHODS: We conducted a systematic review and meta-analysis. We searched PubMed, Embase, Cinahl, Cochrane Library, selected reference lists, and Google Scholar. We included randomised controlled trials (RCTs) published between January 2000 and February 2021 with at least one opioid-free study arm, i.e. no opioids administered preoperatively, during anaesthesia induction, before skin closure, or before emergence from anaesthesia.RESULTS: The study comprised 1934 patients from 26 RCTs. Common interventions included laparoscopic gynaecological surgery, upper gastrointestinal surgery, and breast surgery. There is firm evidence that opioid-free anaesthesia significantly reduced adverse post-operative events (OR 0.32, 95% CI 0.22 to 0.46, I2 =56%, p<0.00001), mainly driven by decreased nausea (OR 0.27, (0.17 to 0.42), p<0,00001) and vomiting (OR 0.22 (0.11 to 0.41), p<0.00001). Postoperative opioid consumption was significantly lower in the opioid-free group (-6.00 mg (-8.52 to -3.48), p<0.00001). There was no significant difference in length of post-anaesthesia care unit stay and overall postoperative pain between groups.CONCLUSIONS: Opioid-free anaesthesia can improve postoperative outcomes in several surgical settings without evidence of adverse effects on patient safety and pain management. There is a need for more evidence-based non-opioid anaesthetic protocols for different types of surgery as well as postoperative phases.

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: The purpose of this study was to describe the experiences of critical care nurses (CCNs) and registered nurse anesthetists (RNAs) when monitoring and observing infants and toddlers recovering from anesthesia. DESIGN: A qualitative design with a critical incident approach.METHODS: Semistructured individual interviews were conducted with a purposeful sample of CCNs and RNAs (n = 17) from postanesthesia care units at two hospitals. The critical incident technique approach was used to guide the interviews, and data were analyzed inductively using thematic analysis.FINDINGS: The main finding was the CCNs' and RNAs' description of how they "watch over the children and stay close" to provide emotional and physical safety. CCNs' and RNAs' experiences of observing and managing the children's small, immature airways were reflected in the theme "using situation awareness of the small, immature airways." The theme "understanding emergence agitation" describes the challenge that arises when children are anxious, feel insecure, and have pain, and the theme "having parents nearby" shows the necessity and value of involving parents in their children's care.CONCLUSIONS: Findings from this study suggest that caring for infants and toddlers recovering from anesthesia requires experience and both technical and nontechnical skills. These are prerequisites for achieving readiness for planning, setting priorities, and adapting one's behavior if an adverse event occurs. Alertness and the ability to solve acute problems and make quick decisions are essential because of the risks associated with children's small, immature airways, as is the ability to understand and respond to emergence agitation. Having parents nearby is equally important for creating the conditions for compassionate child- and family-centered care.

- Postoperative nausea and vomiting "the little big problem" after surgery/anaesthesia is still a common side-effect compromising quality of care, delaying discharge and resumption of activities of daily living. A huge number of studies have been conducted in order to identify risk factors, preventive and therapeutic strategies. The Apfel risk score and a risk based multi-modal PONV prophylaxis is advocated by evidence based guidelines as standards of care but is not always followed. Tailored anaesthesia and pain management avoiding too liberal dosing of anaesthetics and opioid analgesics is also essential in order to reduce risk. Thus multi-modal opioid sparing analgesia and a risk based PONV prophylaxis should be provided in order to minimise the occurrence. There is however still no way to guarantee an individual patient that he or she should not experience any PONV. Further studies are needed trying to identify risk factors and ways to tailor the individual patient prevention/therapy are warranted.The present paper provides a review around prediction, factors influencing the occurrence and the management of PONV with a focus on the ambulatory surgical patient.
