Abstract
OBJECTIVES Delirium is a serious complication following neurosurgical procedures. We hypothesise that the beneficial effect of music on a combination of delirium-eliciting factors might reduce delirium incidence following neurosurgery and subsequently improve clinical outcomes. DESIGN Prospective randomised controlled trial. SETTING Single centre, conducted at the neurosurgical department of the Erasmus Medical Center, Rotterdam, the Netherlands. PARTICIPANTS Adult patients undergoing craniotomy were eligible. INTERVENTIONS Patients in the intervention group received preferred recorded music before, during and after the operation until day 3 after surgery. Patients in the control group were treated according to standard of clinical care. PRIMARY AND SECONDARY OUTCOME MEASURES Primary outcome was presence or absence of postoperative delirium within the first 5 postoperative days measured with the Delirium Observation Screening Scale (DOSS) and, in case of a daily mean score of 3 or higher, a psychiatric evaluation with the latest Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria. Secondary outcomes included anxiety, heart rate variability (HRV), depth of anaesthesia, delirium severity and duration, postoperative complications, length of stay and location of discharge. RESULTS We enrolled 189 patients (music=95, control=94) from July 2020 through September 2021. Delirium, as assessed by the DOSS, was less common in the music (n=11, 11.6%) than in the control group (n=21, 22.3%, OR:0.49, p=0.048). However, after DSM-5 confirmation, differences in delirium were not significant (4.2% vs 7.4%, OR:0.47, p=0.342). Moreover, music increased the HRV (root mean square of successive differences between normal heartbeats, p=0.012). All other secondary outcomes were not different between groups. CONCLUSION Our results support the efficacy of music in reducing the incidence of delirium after craniotomy, as found with DOSS but not after DSM-5 confirmation, substantiated by the effect of music on preoperative autonomic tone. Delirium screening tools should be validated and the long-term implications should be evaluated after craniotomy.

Abstract
Injectable antipsychotics had been used for patients who refuse oral medications in delirium practice. The objectives were to investigate acceptability of transdermal antipsychotic patches by patients who refuse oral medications and their effectiveness in preventing recurrence of delirium. In this retrospective observational study, data were collected between October 2019 and December 2021. The sample was represented by patients hospitalized because of acute diseases or elective surgery who had delirium on the night before the consultation and had refused oral therapy after consultation. Delirium has been diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Instead, a transdermal patch of blonanserin, a second-generation antipsychotic drug, was tried. The primary outcome was the rate of patients who accepted it. The secondary outcome was recurrence rates of delirium. As much as 95.1% of patients who refused oral medications (98/103 patients) accepted to receive the transdermal patch. Of these, 24 patients developed delirium again, whereas all five patients who refused it developed delirium again [24.5% (24/98) vs. 100% (5/5); P = 0.0014]. The present findings suggest that transdermal antipsychotic patches are more likely to be accepted by patients who refuse oral medications. Prospective studies are needed.

Abstract
OBJECTIVES Postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) are common operative neurocognitive disorders, which places a heavy burden on patients, families and society. Therefore, it is very important to search for preventive drugs. Previous studies have demonstrated that perioperative use of dexmedetomidine resulted in a decrease the incidence of POD and POCD. But the specific effect of dexmedetomidine on elderly patients undergoing hepatic lobectomy and its potential mechanism are not clear. This study aims to evaluate the efficacy of intraoperative use of dexmedetomidine on preventing POD and POCD in elderly patients undergoing hepatic lobectomy and the influence on the balance between proinflammation and anti-inflammation. METHODS This trial was designed as a single-center, prospective, randomized, controlled study. One hundred and twenty hospitalized patients from January 2019 to December 2020, aged 60-80 years old with American Society of Anesthesiologists (ASA) II-III and scheduled for hepatic lobectomy, were randomly allocated into 3 groups (n=40) using a random number table: A C group, a Dex1 group, and a Dex2 group. After anesthesia induction, saline in the C group, dexmedetomidine [0.3 μg/(kg·h)] in the Dex1 group, and dexmedetomidine [0.6 μg/(kg·h)] in the Dex2 group were infused until the end of operation. The incidences of hypotension and bradycardia were compared among the 3 groups. Confusion Assessment Method (CAM) for assessing POD and Mini Mental State Examination (MMSE) for evaluating POCD were recorded and venous blood samples were obtained for the determination of neuron specific enolase (NSE), TNF-α, IL-1β, and IL-10 at the different time below: the time before anesthesia (T0), and the first day (T1), the third day (T2), the fifth day (T3), and the seventh day (T4) after operation. RESULTS Compared with the C group, the incidences of bradycardia in the Dex1 group or the Dex2 group increased (both P<0.05) and there was no difference in hypotension in the Dex1 group or the Dex2 group (both P>0.05). The incidences of POD in the C group, the Dex1 group, and the Dex2 group were 22.5%, 5.0%, and 7.5%, respectively. The incidences of POD in the Dex1 group or the Dex2 group declined significantly as compared to the C group (both P<0.05). However, there is no difference in the incidence of POD between the Dex1 group and the Dex2 group (P>0.05). The incidences of POCD in the C group, the Dex1 group, and the Dex2 group were 30.0%, 12.5%, and 10.0%, respectively. The incidences of POCD in the Dex1 group and the Dex2 group declined significantly as compared to the C group (both P<0.05). And no obvious difference was seen in the incidence of POCD in the Dex1 group and the Dex2 group (P>0.05). Compared with the C group, the level of TNF-α and IL-1β decreased and the level of IL-10 increased at each time points (from T1 to T4) in the Dex1 group and the Dex2 group (all P<0.05). Compared with the Dex1 group, the level of IL-1β at T2 and IL-10 from T1 to T3 elevated in the Dex2 group (all P<0.05). Compared with the T0, the concentrations of NSE in C group at each time points (from T1 to T4) and in the Dex1 group and the Dex2 group from T1 to T3 increased (all P<0.05). Compared with the C group, the level of NSE decreased from T1 to T4 in the Dex1 group and the Dex2 group (all P<0.05). CONCLUSIONS Intraoperative dexmedetomidine infusion can reduce the incidence of POCD and POD in elderly patients undergoing hepatic lobectomy, and the protective mechanism appears to involve the down-regulation of TNF-α and IL-1β and upregulation of IL-10 expression, which lead to rebalance between proinflammation and anti-inflammation.

Abstract
INTRODUCTION Delirium is a neurocognitive disorder characterised by an acute and temporary decline of mental status affecting attention, awareness, cognition, language and visuospatial ability. The underlying pathophysiology is driven by neuroinflammation and cellular oxidative stress.Delirium is a serious complication following neurosurgical procedures with a reported incidence varying between 4% and 44% and has been associated with increased length of hospital stay, increased amount of reoperations, increased costs and mortality.Perioperative music has been reported to reduce preoperative anxiety, postoperative pain and opioid usage, and attenuates stress response caused by surgery. We hypothesize that this beneficial effect of music on a combination of delirium eliciting factors might reduce delirium incidence following neurosurgery and subsequently improve clinical outcomes. METHODS This protocol concerns a single-centred prospective randomised controlled trial with 6 months follow-up. All adult patients undergoing a craniotomy at the Erasmus Medical Center in Rotterdam are eligible. The music group will receive recorded music through an overear headphone before, during and after surgery until postoperative day 3. Patients can choose from music playlists, offered based on music importance questionnaires administered at baseline. The control group will receive standard of clinical careDelirium is assessed by the Delirium Observation Scale and confirmed by a delirium-expert psychiatrist according to the DSM-5 criteria. Risk factors correlated with the onset of delirium, such as cognitive function at baseline, preoperative anxiety, perioperative medication use, depth of anaesthesia and postoperative pain, and delirium-related health outcomes such as length of stay, daily function, quality of life (ie, EQ-5D, EORTC questionnaires), costs and cost-effectiveness are collected. ETHICS AND DISSEMINATION This study is being conducted in accordance with the Declaration of Helsinki. The Medical Ethics Review Board of Erasmus University Medical Center Rotterdam, The Netherlands, approved this protocol. Results will be disseminated via peer-reviewed scientific journals and conference presentations. TRIAL REGISTRATION NUMBERS NL8503 and NCT04649450.

Comparison of Dexmedetomidine and Etomidate on Intraoperative Wake-Up Equality, Hemodynamics, and Cerebral Protection in Operation of the Brain Functional Area. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:6363188. [PMID: 34484398 PMCID: PMC8416374 DOI: 10.1155/2021/6363188] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Accepted: 08/18/2021] [Indexed: 01/18/2023]
Abstract
In recent years, with the increasing incidence of brain functional area tumors, the clinical application of functional area tumor resection has become extremely urgent. Intraoperative wake-up is an important auxiliary method of this operation, which can effectively reduce the damage of the brain function area caused by the operation and anesthesia itself while playing the role of auxiliary function area and tumor positioning. However, the intraoperative wake-up requires a higher anesthesia effect, so higher requirements are put forward for the choice of anesthetic drugs. Based on hemodynamic and serum molecular observations, this study found that dexmedetomidine- and etomidate-assisted anesthesia were used for intraoperative wake-up in brain functional area surgery, both of which could maintain hemodynamic stability. In addition, the arousal effect and brain protection of dexmedetomidine were better than those of etomidate, and the incidence of adverse reactions was lower during the arousal period. This can provide relevant reference for clinical improvement of the anesthesia effect and surgical safety of intraoperative wake-up.

Abstract
Background Postoperative delirium (POD) is a condition of cerebral dysfunction and a common complication after surgery. This study aimed to compare and determine the relative efficacy of pharmacological interventions for preventing POD using a network meta-analysis. Methods We performed a systematic and comprehensive search to identify and analyze all randomized controlled trials until June 29, 2020, comparing two or more pharmacological interventions, including placebo, to prevent or reduce POD. The primary outcome was the incidence of POD. We performed a network meta-analysis and used the surface under the cumulative ranking curve (SUCRA) values and rankograms to present the hierarchy of the pharmacological interventions evaluated. Results According to the SUCRA value, the incidence of POD decreased in the following order: the combination of propofol and acetaminophen (86.1%), combination of ketamine and dexmedetomidine (86.0%), combination of diazepam, flunitrazepam, and pethidine (84.8%), and olanzapine (75.6%) after all types of anesthesia; combination of propofol and acetaminophen (85.9%), combination of ketamine and dexmedetomidine (83.2%), gabapentin (82.2%), and combination of diazepam, flunitrazepam, and pethidine (79.7%) after general anesthesia; and ketamine (87.1%), combination of propofol and acetaminophen (86.0%), and combination of dexmedetomidine and acetaminophen (66.3%) after cardiac surgery. However, only the dexmedetomidine group showed a lower incidence of POD than the control group after all types of anesthesia and after general anesthesia. Conclusions Dexmedetomidine reduced POD compared with the control group. The combination of propofol and acetaminophen and the combination of ketamine and dexmedetomidine seemed to be effective in preventing POD. However, further studies are needed to determine the optimal pharmacological intervention to prevent POD.

Abstract
Background Risk prediction models allow clinicians to forecast which individuals are at a higher risk for developing a particular outcome. We developed and internally validated a delirium prediction model for incident delirium parameterized to patient ICU admission acuity. Methods This retrospective, observational, fourteen medical-surgical ICU cohort study evaluated consecutive delirium-free adults surviving hospital stay with ICU length of stay (LOS) greater than or equal to 24 hours with both an admission APACHE II score and an admission type (e.g., elective post-surgery, emergency post-surgery, non-surgical) in whom delirium was assessed using the Intensive Care Delirium Screening Checklist (ICDSC). Risk factors included in the model were readily available in electric medical records. Least absolute shrinkage and selection operator logistic (LASSO) regression was used for model development. Discrimination was determined using area under the receiver operating characteristic curve (AUC). Internal validation was performed by cross-validation. Predictive performance was determined using measures of accuracy and clinical utility was assessed by decision-curve analysis. Results A total of 8,878 patients were included. Delirium incidence was 49.9% (n = 4,431). The delirium prediction model was parameterized to seven patient cohorts, admission type (3 cohorts) or mean quartile APACHE II score (4 cohorts). All parameterized cohort models were well calibrated. The AUC ranged from 0.67 to 0.78 (95% confidence intervals [CI] ranged from 0.63 to 0.79). Model accuracy varied across admission types; sensitivity ranged from 53.2% to 63.9% while specificity ranged from 69.0% to 74.6%. Across mean quartile APACHE II scores, sensitivity ranged from 58.2% to 59.7% while specificity ranged from 70.1% to 73.6%. The clinical utility of the parameterized cohort prediction model to predict and prevent incident delirium was greater than preventing incident delirium by treating all or none of the patients. Conclusions Our results support external validation of a prediction model parameterized to patient ICU admission acuity to predict a patients’ risk for ICU delirium. Classification of patients’ risk for ICU delirium by admission acuity may allow for efficient initiation of prevention measures based on individual risk profiles.

Abstract
INTRODUCTION Postoperative delirium is a common sequela in older adults in the peri-operative period leading to poor outcomes with a complex pathophysiology which has led to a variety of different pharmacologic agents employed in attempts to prevent and treat this syndrome. No pharmacologic agent has been approved to treat this disorder, but this review discusses the pharmacologic strategies which have been tried based on the hypotheses of the causation of the syndrome including neurotransmitter imbalance, inflammation, and oxidative stress. AREAS COVERED Systematic reviews and meta-analyses of randomized clinical trials (RCTs) were included via search of electronic databases specifically for the terms postoperative delirium and pharmacologic treatments. With this approach, the recurrent topics of analgesia and sedation, antipsychotics, acetylcholinesterase inhibitors (AchE-Is), inflammation, and melatonin were emphasized and provided the outline for this review. EXPERT OPINION Research evidence does not support any particular agent in any of the pharmacologic classes reviewed. However, there is some potential benefit with dexmedetomidine, melatonin, and the monitoring of anesthetic agents all of which need further clinical trials to validate these conclusions. Exploration of ways to improve studies and the application of novel pharmacologic agents may offer future benefit.

Abstract
We designed this experimental study with a view to evaluate the effects of dexmedetomidine (DEX) on cardiac performance and systemic and peripheral hemodynamics in healthy and early-stage endotoxemia swine models. Our study hypothesis was that DEX can ensure hemodynamic stability during the course of endotoxemia. Thirty-two male pigs (25-27 kg) were assigned into four groups: (1) no intervention (group A), (2) DEX 0.8 μg/kg was administered in non-septic animals (group B), (3) sepsis induced by intravenous Escherichia coli endotoxin (group C) and (4) DEX 0.8 μg/kg was administered in septic animals (group D). Hemodynamic parameters such as heart rate, mean blood pressure, central venous pressure, pulmonary artery pressures, pulmonary artery occlusion pressure, pulmonary vascular resistance and cardiac output were continuously recorded. Central venous oxygen saturation was also measured in order to obtain a complete evaluation of cardiovascular response to sepsis. Heart rate was decreased, whilst mean arterial pressure decrease was alleviated after DEX administration in septic animals. In addition, central venous pressure was stable in animals with sepsis after DEX infusion. Sepsis dramatically elevated pulmonary function indicators but DEX succeeded in ameliorating this effect. The important decrease measured in central venous oxygen saturation in both sepsis groups reflected the decreased perfusion of tissues that takes place at the end of early sepsis. Our findings support the hypothesis that DEX has beneficial effects on heart rate and pulmonary artery pressure, whilst reduction in systemic blood pressure occurs at acceptable levels.
