[Non-pharmacological Management of Postoperative Delirium]. / Nicht pharmakologisches Management des postoperativen Delirs.

Postoperative delirium is common especially in the elderly and is associated with high rates of morbidity and mortality. Non-pharmacological multicomponent interventions are effective in reducing the incidence and to a degree the duration of postoperative delirium and are recommended in international guidelines on postoperative delirium as first line intervention for management of delirium. Non-pharmacological management of postoperative delirium consists of strategies for risk stratification, risk reduction by non-pharmacological bundle interventions, early recognition of delirium by screening protocols and immediate therapy of underlying causes of delirium and continuation of non-pharmacological bundles. Non-pharmacological bundle interventions address common perioperative risk factors. Bundles comprise strategies for oxygenation, mobilization, hydration and nutrition, sensory and cognitive stimulation, reorientation, modifications of environmental factors such as design aspects and noise reduction, adequate analgesia, management of agitation and anxiety, protecting circadian rhythms for example by adequate light exposure during daytime, family involvement and timely reduction of unnecessary catheters and anticholinergic drugs. The article aims at providing an overview of non-pharmacological management of postoperative delirium in the hospital.

Update on Perioperative Delirium.

A strong association between frailty and in-hospital delirium in nonsurgical patients has been shown. Physical and cognitive frailties have been associated with decline and dysfunction in the frontal cognitive domains. Risk factors for frailty are similar to risk factors for postoperative delirium (POD). Frailty can be screened and diagnosed by various tools and instruments. Different anesthetic techniques have been studied to decrease the incidence of POD. However, no anesthetic technique has been conclusively proven to decrease the risk of POD. Patients with dementia develop delirium more often, and delirium is associated with accelerated cognitive decline.

[Excited Delirium Syndrome (ExDS): emergence and emergency management]. / Erregungssturm ­ Entstehung und Notfallbehandlung.

The Excited Delirium Syndrome (ExDS) is a state of maximum psychophysiological excitation far beyond mental agitation. Patients themselves are at an acute risk and put others at a high risk. We present data from eleven patients and a short literature review. Results: 9 of 11 patients were acutely intoxicated (alcohol, magic mushrooms, THC, ecstacy, or "flakka"). Eight had a history of substance abuse and 4 of other mental illness. None of the patients responded to attempts at verbal de-escalation. Seven had significant injuries at the time of admission to the hospital. The aggressive "psychiatric" presentation of ExDS can lead to vital risks being overlooked (hyperexcitation, acidosis, rhabdomyolysis, hypoxemia, and cardiovascular decompensation), which may even be increased by severe methods of restraint (hogtie; positional asphyxia). Early recognition of ExDS and its risks, comprehensive management and the prevention of inappropriate treatment will help to reduce fatal outcomes.

Reliability and Validity Testing of the Quantified Quality of Interaction Schedule.

BACKGROUND AND PURPOSE: The purpose of this study was to test the reliability and validity of the Quality of Interactions Schedule (QuIS) using a quantification scoring approach. METHODS: Baseline data from the Evidence Integration Triangle for Behavioral and Psychological Symptoms of Dementia (EIT-4-BPSD) study was used. RESULTS: A total of 553 residents participated. There was evidence of inter-rater reliability with Kappa scores of .86 to 1.00 and internal consistency based on the Rasch analysis (item reliability of .98). There was some support for validity based on item fit and hypothesis testing as resistiveness to care was significantly associated with total QuIS scores. CONCLUSION: This study supports the use of the quantified QuIS to evaluate the quality of interactions over time and to test interventions to improve interactions.

Acupuncture for postoperative delirium (POD): A systematic review and meta-analysis protocol.

BACKGROUND: Postoperative delirium (POD) is a form of delirium that is newly diagnosed after a surgical procedure. This study aims to examine the effectiveness and safety of acupuncture treatment for POD in patients who underwent surgery. METHODS: Randomized controlled trials for patients diagnosed with POD using validated delirium assessment scales will be included in this review. Electronic databases, such as MEDLINE, EMBASE, CENTRAL, CINAHL (English DB), CNKI, Wanfang, VIP (Chinese database), KoreaMed, RISS, KISS, DBpia, OASIS (Korean DB), and J-STAGE (Japanese DB) will be searched without language limitation from their inception to October 2020. The intervention group will include patients who have received any type of acupuncture treatment for POD. The control group will include individuals with no treatment, sham acupuncture treatment, and conventional treatment. The primary outcome is the incidence of POD in each study. Quality assessment will be performed using the Cochrane risk of bias tool. A meta-analysis will be performed to pool the estimated effect. CONCLUSION: This study will provide evidence for acupuncture as a potential treatment for POD, in researchers, patients, and policy makers. DISSEMINATION: The result of the study will be disseminated through posters, press releases, conference presentations, and peer-reviewed papers.

Weaning From Exogenous Sedation in the Era of COVID-19 Infection: Recommendations for Sedation and Its Discontinuation.

The Psychiatric Consultation Service at Massachusetts General Hospital sees medical and surgical inpatients with comorbid psychiatric symptoms and conditions. During their twice-weekly rounds, Dr Stern and other members of the Consultation Service discuss diagnosis and management of hospitalized patients with complex medical or surgical problems who also demonstrate psychiatric symptoms or conditions. These discussions have given rise to rounds reports that will prove useful for clinicians practicing at the interface of medicine and psychiatry.

Clinical practice in the management of postoperative delirium by Chinese anesthesiologists: a cross-sectional survey designed by the European Society of Anaesthesiology.

OBJECTIVE: In this survey, we assessed the current clinical management of postoperative delirium (POD) among Chinese anesthesiologists, after publishing the European POD guideline. METHODS: We administered an electronic survey, designed according to the European POD guideline. The survey was completed using mobile devices. RESULTS: In total, 1,514 respondents from China participated in the survey. Overall, 74.4% of participants reported that delirium is very important. More than 95% of participants stated that they routinely assessed POD. In total, 61.4% screened for POD using clinical observation and 37.6% used a delirium screening tool. Although the depth of anesthesia (a POD risk factor) was monitored, electroencephalogram monitoring was unavailable to 30.6% of respondents. Regarding treatment, only 24.1% of respondents used a standard algorithm; 58.5% used individualized treatment. CONCLUSION: Our survey showed that there are high awareness levels among Chinese anesthesiologists regarding the importance of POD. However, routine assessment and monitoring of all patients, including perioperative anesthesia depth monitoring, and a treatment algorithm need to be implemented on a larger scale. According to the results, efforts should be made to improve the knowledge of POD among Chinese anesthesiologists.

Routine management of postoperative delirium outside the ICU: Results of an international survey among anaesthesiologists.

BACKGROUND: Postoperative delirium (POD) is a severe brain dysfunction. Although data indicate a high relevance, no survey has investigated the routine practice to monitor delirium outside the ICU setting after surgery. Prior to publishing of the new European Society of Anaesthesiology (ESA) guidelines on POD, an international survey was conducted to assess current practice. METHODS: European Society of Anaesthesiology-endorsed online survey; Trial Registration: NCT-identifier: 02513537. RESULTS: In total, 566 respondents from 62 countries accessed, and 564 (99.6%) completed the survey (completion rate). Overall, 385 (68%) of the respondents reported that delirium is either "very relevant" or "relevant" for their daily clinical practice. In all, 38 (7%) of the respondents routinely monitor for delirium in >50% of all patients. Asked on the monitoring time point, more than half (n = 308, 55%) indicated to screen before or at recovery room discharge, 235 (42%) up to the first postoperative day, 143 (25%) up to 3 days, and 77 (14%) up to 5 postoperative days. Although there is a lack of long-term monitoring, nearly all respondents (n = 530, 94%) reported to treat delirium. Availability of EEG/EMG-based monitoring to assess the depth of anaesthesia was high in the study group (n = 547, 97%) and was used by more than one-third of the respondents to reduce risk of burst suppression (n = 189, 34%). CONCLUSION: Although delirium is perceived as a relevant condition among anaesthesiologists, there is a high demand for implementing monitoring strategies after publishing of the POD Guideline. The survey shows that tools necessary for POD Guideline implementation are available in the centres represented by the respondents.

State of the clinical science of perioperative brain health: report from the American Society of Anesthesiologists Brain Health Initiative Summit 2018.

Cognitive recovery after anaesthesia and surgery is a concern for older adults, their families, and caregivers. Reports of patients who were 'never the same' prompted a scientific inquiry into the nature of what patients have experienced. In June 2018, the ASA Brain Health Initiative held a summit to discuss the state of the science on perioperative cognition, and to create an implementation plan for patients and providers leveraging the current evidence. This group included representatives from the AARP (formerly the American Association of Retired Persons), American College of Surgeons, American Heart Association, and Alzheimer's Association Perioperative Cognition and Delirium Professional Interest Area. This paper summarises the state of the relevant clinical science, including risk factors, identification and diagnosis, prognosis, disparities, outcomes, and treatment of perioperative neurocognitive disorders. Finally, we discuss gaps in current knowledge with suggestions for future directions and opportunities for clinical and translational projects.

Frequency, predictive factors and therapy of emergence delirium: data from a large observational clinical trial in a broad spectrum of postoperative pediatric patients.

BACKGROUND: Emergence delirium (ED) is an important postanesthetic complication in children. Although it has been thoroughly studied, data on frequency, predictive factors, and therapy of this phenomenon are inconclusive. In this study, we seek to obtain a better understanding of the frequency of ED and different therapeutic approaches, making use of the large amount of patients in our university hospital. METHODS: After approval by the local ethics committee, patients aged zero to 13 years, who were treated in the post anesthesia care of our hospital, were investigated in this observational study. ED was diagnosed on basis of a clinical evaluation as well as with the Pediatric Anesthesia Emergence Delirium (PAED) Scale. RESULTS: In 86 of 821 patients a PAED-Score≥10 and therefore an ED was detected (10.5%). Based on clinical assessment by the PACU staff only 5.7% experienced an ED. Age

Current Evidence-Based Practice for Pediatric Emergence Agitation.

This article provides a systematic review of pediatric emergence agitation, also known as emergence delirium. Major topics of this review include the incidence, risk factors, and impact of the phenomenon, in addition to current evidence-based strategies for prevention of pediatric emergence agitation. Emergence agitation causes tremendous psychological distress for the patient, family, and healthcare providers, as well as concerns for physical safety. Risk factors for pediatric emergence agitation are the child's age, genetic profile, length and type of surgical procedure, and use of inhalational anesthesia. In an attempt to prevent this problem, anesthesia providers should consider these factors and possible interventions when implementing an anesthetic plan. Evidence-based interventions that may decrease the incidence of pediatric emergence agitation include technology, familial involvement, pharmacologic adjuncts, and alternative methods of general anesthesia.

[Drama in the Recovery Unit: Paediatric Emergence Delirium]. / Drama im Aufwachraum: pädiatrisches Emergence-Delir.

The upcoming and ongoing debate on neurotoxicity of anesthetics at a young age put a new spotlight on the emergence delirium of children (paedED). The European Society for Anesthesiology published a consensus guideline on prevention and therapy in 2017 which can be a useful guidance in daily clinical practice. Patient data management systems with their clear documentation concerning pain/therapy of pain and paedED will be valuable tools in order to assess the real incidence of paedED. Differentiating between pain/agitation and paedED migth not always be easy. Age-adapted scores should always be applied. Main focus in the prevention of paedED is the reduction of anxiety. The way this is achieved by the dedicated pediatric anesthesia teams caring for children, e.g. by oral midazolam, clowns, music, smartphone induction, does not matter. Using α2-agonists in the perioperative phase and applying propofol seems to be effective. A quiet supportive environment for recovery adds to a relaxed, stress-free awakening. For the future detecting paedED on normal wards becomes an important issue. This may be achieved by structured interviews or questionnaires assessing postoperative negative behavioural changes at the same time.

ICU delirium - a diagnostic and therapeutic challenge in the intensive care unit.

ICU delirium is a common medical problem occurring in patients admitted to the intensive care units (ICUs). Studies have shown that ICU delirium is associated with increased mortality, prolonged hospitalization, prolonged mechanical ventilation, costs and the occurrence of cognitive disoders after discharge from ICU. The tools available for ICU delirium screening and diagnosis are validated tests available for all members if the medical team (physicians, nurses, physiotherapists). Their use for routine patient assessment is recommended by international medical and scientific societies. They have been implemented as Pain, Agitation, Delirium (PAD) Guidelines by the Society of Critical Care Medicine. Apart from monitoring, a strategy of prevention and treatment is recommended, based on non-pharmacological approach (restoration of senses, early mobilization, physiotherapy, improvement in sleep hygiene and family involvement) as well as pharmacological treatment (typical and atypical antipsychotics and dexmedetomidine). In this article, we present the risk factors of ICU delirium, available tools for monitoring, as well as options for prevention and treatment of delirium that can be used to improve care over critically ill patients.

Peri-operative neurological complications.

Brain injury from cardiac surgery is an important source of patient morbidity and mortality. The relationship between risk of brain injury and advanced age portends a rising frequency of these complications due to an increasing proportion of elderly patients undergoing cardiac surgery. This review will explore the aetiology and risk factors for peri-operative stroke, postoperative cognitive dysfunction and postoperative delirium. The prevention of each of these conditions will also be discussed, with a focus on brain protection strategies and the avoidance of cerebral embolism and hypoperfusion.

Bright light and oxygen therapies decrease delirium risk in critically ill surgical patients by targeting sleep and acid-base disturbances.

This study examined the effects of bright light therapy (BLT) on the incidence of delirium in post-operative patients admitted to a surgical intensive care unit (SICU) and delineates risk and protective factors. We included 62 patients in a single-blind, randomized controlled study. The intervention group was treated with care as usual plus BLT for three consecutive days. Delirium was diagnosed by DSM-5 criteria with the Confusion Assessment Method-Intensive Care Unit (CAM-ICU). Risk factors for delirium were measured, including the APACHE II score, Insomnia Severity Index (ISI), as well as hematocrit and bicarbonate levels. Results were adjusted for treatment with nasal cannula oxygen and medications. Thirteen patients developed delirium within the three days following surgery. Generalized estimating equations analysis showed a significant preventive effect of BLT on delirium, which was independent of risk or treatment factors. Higher APACHE-II and ISI scores, lower hematocrit and lower bicarbonate levels increased the risk of developing delirium. BLT plus nasal cannula oxygen significantly reduced the likelihood of delirium. BLT significantly lowered ISI scores, while nasal cannula oxygen significantly enhanced bicarbonate levels. The results indicate that BLT and supplementary oxygen therapy may protect against delirium by targeting sleep-wake and deficits in the bicarbonate buffer system.
