    This is a cross-sectional, two-year follow up study. The authors determined the varied presentations of delirium, dementia and other organic disorders to assess their mortality and outcome. They described the diagnosis of patients suffering from the psychiatric effects of those organic states and compared their symptom resolution and mortality between those with the acute and chronic varieties during their index hospitalization and again, 24 months later. Although mortality rates did not differ, patients with the acute syndrome had significantly better outcomes in terms of symptom resolution as compared to those with the chronic syndrome (p=0.001). Patients with symptom resolution upon discharge did not show statistically significant lower mortality rates.

    Delirium is common in intensive care patients. Dexmedetomidine is increasingly used for sedation in this setting, but its effect on delirium remains unclear. The primary aim of this review was to examine whether dexmedetomidine reduces the incidence of delirium and agitation in intensive care patients. We sought randomised clinical trials in MEDLINE, EMBASE, PubMed and CENTRAL from their inception until June 2018. Observational studies, case reports, case series and non-systematic reviews were excluded. Twenty-five trials including 3240 patients were eligible for inclusion in the data synthesis. In the patients who received dexmedetomidine (eight trials, 1425 patients), delirium was reduced, odds ratio (95%CI) 0.36 (0.26-0.51), p delirium, bradycardia and hypotension was conclusive but not for the incidence of agitation and mortality. In summary, this meta-analysis suggests that dexmedetomidine reduces the incidence of delirium and agitation in intensive care patients. The general quality of evidence ranged from moderate to high.

    High prevalence of cerebral desaturation is associated with postoperative neurological complications in cardiac surgery. However, the evidence use of cerebral oximetry by correcting cerebral desaturation in the reduction of postoperative complications remains uncertain in the literature. This systematic review and meta-analysis aimed to examine the effect of cerebral oximetry on the incidence of postoperative cognitive dysfunction in cardiac surgery. Databases of MEDLINE, EMBASE, and CENTRAL were searched from their inception until April 2021. All randomized controlled trials comparing cerebral oximetry and blinded/no cerebral oximetry in adult patients undergoing cardiac surgery were included. Observational studies, case series, and case reports were excluded. A total of 14 trials (n = 2,033) were included in this review. Our pooled data demonstrated that patients with cerebral oximetry were associated with a lower incidence of postoperative cognitive dysfunction than the control group (studies = 4, n = 609, odds ratio [OR]: 0.15, 95% confidence interval [CI]: 0.04 to 0.54, P = 0.003, I2 = 88%; certainty of evidence = very low). In terms of postoperative delirium (OR: 0.75, 95%CI: 0.50-1.14, P = 0.18, I2 = 0%; certainty of evidence = low) and postoperative stroke (OR: 0.81 95%CI: 0.37-1.80, P = 0.61, I2 = 0%; certainty of evidence = high), no significant differences (P > 0.05) were reported between the cerebral oximetry and control groups. In this meta-analysis, the use of cerebral oximetry monitoring in cardiac surgery demonstrated a lower incidence of postoperative cognitive dysfunction. However, this finding must be interpreted with caution due to the low level of evidence, high degree of heterogeneity, lack of standardized cognitive assessments, and cerebral desaturation interventions.

    Dexmedetomidine is a highly selective α2-adrenoceptor agonist, which is off-labelled use for pediatric sedation. However, the hemodynamic responses of dexmedetomidine remain unclear in the pediatric population. The primary objectives of this systematic review and meta-analysis were to examine the hemodynamic effects of high-dose and low-dose dexmedetomidine in pediatric patients undergoing surgery. EMBASE, MEDLINE, and CENTRAL were systematically searched from its inception until April 2019. All randomized clinical trials comparing high-dose (> 0.5 mcg/kg) and low-dose (≤ 0.5 mcg/ kg) dexmedetomidine in pediatric surgical patients were included, regardless of the types of surgeries. Observational studies, case series, and case reports were excluded. Four trials (n = 473) were included in this review. Our review demonstrated that high-dose dexmedetomidine was associated with lower heart rate than low-dose dexmedetomidine after intravenous bolus of dexmedetomidine (studies, 3; n = 274; mean difference [MD], -5 [-6 to -4]; P < 0.0001) and during surgical stimulant (studies, 2; n = 153; MD, -11 [-13 to -9]; P < 0.0001). In comparison to the low-dose dexmedetomidine, high-dose dexmedetomidine was also associated with a significant longer recovery time (studies, 3; n = 257; MD, 5.90 [1.56 to 10.23]; P = 0.008) but a lower incidence of emergence agitation (studies, 2; n = 153; odds ratio, 0.17 [0.03 to 0.95]; P = 0.040). In this meta-analysis, low-dose dexmedetomidine demonstrated better hemodynamic stability with shorter recovery time than high-dose dexmedetomidine. However, these findings need to be interpreted with caution due to limited published studies, a small sample size, and a high degree of heterogeneity.

    BACKGROUND: Electroconvulsive therapy (ECT) is safe and efficacious in the elderly population. However, clinicians are still weary to use it among the old-old population, citing safety concerns. Our case report highlights the use of ECT in a 91 year old lady with late onset Bipolar Mania.

    CASE REPORT: A 91 year old lady presented with an acute manic relapse for the past 2 weeks. She was previously on oral Sodium Valproate, and during this current admission was augmented with oral Quetiapine IR 100 mg bd. She remained unwell and was planned for right unilateral ECT with age-based dosing stimuli. After only 4 sessions, she showed complete resolution of her manic symptoms.

    RESULT: In our case study, the patient showed rapid response to right unilateral ECT. Even though the Post Suppression Index (PSI) was not significant, there is some evidence that in elderly patients, burst suppression (not measured in this case) may be more accurate measure of ECT efficacy. The transient treatment emergent delirium was short lived and ECT was very tolerated in this patient.

    CONCLUSION: Clinicians should not delay ECT in old-old patients who do not respond to pharmacologic treatment, as early switch to ECT results in rapid response with good safety profile.

    A patient with bipolar I disorder has been treated with lithium and haloperidol for the last 20 years and received an ACE inhibitor for his hypertension since 9 years ago. Despite regular clinic follow-ups and blood monitoring, he recently developed tremors and delirium. On hospital admission, serum level of lithium was far above toxic level. Mental state examination revealed an anxious and disorientated man with irrelevant speech. Immediate discontinuation of lithium resulted in slow reduction of serum lithium levels and gradual resolution of tremor but his delirium persisted for 2 weeks. His condition took a turn for the worse when he developed acute renal failure and arm abscess. We discussed about lithium toxicity and the vulnerability factors which have induced delirium and renal failure in this patient.

    OBJECTIVES: In the absence of a universal definition of light or deep sedation, the level of sedation that conveys favorable outcomes is unknown. We quantified the relationship between escalating intensity of sedation in the first 48 hours of mechanical ventilation and 180-day survival, time to extubation, and delirium.

    DESIGN: Harmonized data from prospective multicenter international longitudinal cohort studies SETTING:: Diverse mix of ICUs.

    PATIENTS: Critically ill patients expected to be ventilated for longer than 24 hours.

    INTERVENTIONS: Richmond Agitation Sedation Scale and pain were assessed every 4 hours. Delirium and mobilization were assessed daily using the Confusion Assessment Method of ICU and a standardized mobility assessment, respectively.

    MEASUREMENTS AND MAIN RESULTS: Sedation intensity was assessed using a Sedation Index, calculated as the sum of negative Richmond Agitation Sedation Scale measurements divided by the total number of assessments. We used multivariable Cox proportional hazard models to adjust for relevant covariates. We performed subgroup and sensitivity analysis accounting for immortal time bias using the same variables within 120 and 168 hours. The main outcome was 180-day survival. We assessed 703 patients in 42 ICUs with a mean (SD) Acute Physiology and Chronic Health Evaluation II score of 22.2 (8.5) with 180-day mortality of 32.3% (227). The median (interquartile range) ventilation time was 4.54 days (2.47-8.43 d). Delirium occurred in 273 (38.8%) of patients. Sedation intensity, in an escalating dose-dependent relationship, independently predicted increased risk of death (hazard ratio [95% CI], 1.29 [1.15-1.46]; p < 0.001, delirium hazard ratio [95% CI], 1.25 [1.10-1.43]), p value equals to 0.001 and reduced chance of early extubation hazard ratio (95% CI) 0.80 (0.73-0.87), p value of less than 0.001. Agitation level independently predicted subsequent delirium hazard ratio [95% CI], of 1.25 (1.04-1.49), p value equals to 0.02. Delirium or mobilization episodes within 168 hours, adjusted for sedation intensity, were not associated with survival.

    CONCLUSIONS: Sedation intensity independently, in an ascending relationship, predicted increased risk of death, delirium, and delayed time to extubation. These observations suggest that keeping sedation level equivalent to a Richmond Agitation Sedation Scale 0 is a clinically desirable goal.

    (1) Background: Older people with COVID-19 infection report worse clinical outcomes. There is a paucity of local data and this study aimed to describe the clinical progression of older people admitted to a university hospital in Malaysia with COVID-19 infection. (2) Methods: Older people (≥60 years) admitted with COVID-19 infection confirmed with RT-PCR from 27 February 2020-25 May 2020 were included in this study. Data on patient characteristics, hospital treatment, and inpatient outcomes were collected via hospital-held electronic medical records. Analysis was done to describe the cohort and identify factors associated with inpatient mortality. (3) Results: 26 participants were included (mean age 76.2 years, female 57.7%). All had at least one comorbid condition and half were frail. About 19.2% had non-respiratory (atypical) symptoms; 23.1% had a severe disease that required intensive care unit monitoring; 46.2% were given COVID-19 targeted therapy. Inpatient mortality and overall complication rates were 23.1% and 42.3%, respectively. Delirium on presentation and lower Ct-value were associated with mortality. (4) Conclusions: Older people with COVID-19 infection have severe infection and poor hospital outcomes. Vigilant hospital care is necessary to address their multimorbidity and frailty, along with appropriate treatment for their infection.

    PURPOSE: To ascertain the relationship among early (first 48 h) deep sedation, time to extubation, delirium and long-term mortality.

    METHODS: We conducted a multicentre prospective longitudinal cohort study in 11 Malaysian hospitals including medical/surgical patients (n = 259) who were sedated and ventilated ≥24 h. Patients were followed from ICU admission up to 28 days in ICU with 4-hourly sedation and daily delirium assessments and 180-day mortality. Deep sedation was defined as Richmond Agitation Sedation Score (RASS) ≤-3.

    RESULTS: The cohort had a mean (SD) age of 53.1 (15.9) years and APACHE II score of 21.3 (8.2) with hospital and 180-day mortality of 82 (31.7%) and 110/237 (46.4%). Patients were followed for 2,657 ICU days and underwent 13,836 RASS assessments. Midazolam prescription was predominant compared to propofol, given to 241 (93%) versus 72 (28%) patients (P < 0.0001) for 966 (39.6%) versus 183 (7.5%) study days respectively. Deep sedation occurred in (182/257) 71% patients at first assessment and in 159 (61%) patients and 1,658 (59%) of all RASS assessments at 48 h. Multivariable Cox proportional hazard regression analysis adjusting for a priori assigned covariates including sedative agents, diagnosis, age, APACHE II score, operative, elective, vasopressors and dialysis showed that early deep sedation was independently associated with longer time to extubation [hazard ratio (HR) 0.93, 95% confidence interval (CI) 0.89-0.97, P = 0.003], hospital death (HR 1.11, 95% CI 1.05-1.18, P < 0.001) and 180-day mortality (HR 1.09, 95% CI 1.04-1.15, P = 0.002), but not time to delirium (HR 0.98, P = 0.23). Delirium occurred in 114 (44%) of patients.

    CONCLUSION: Irrespective of sedative choice, early deep sedation was independently associated with delayed extubation and higher mortality, and thus was a potentially modifiable risk in interventional trials.

    OBJECTIVES: Melatonin is an endogenous hormone, which regulates circadian rhythms and promotes sleep. In recent years, several randomised controlled trials examining the prophylactic use of melatonin to prevent delirium were published with conflicting findings. The primary aim of this review was to determine the effect of melatonin on the incidence of delirium in hospitalised patients.

    DATA SOURCES: MEDLINE, EMBASE and CENTRAL were systematically searched from their inception until December 2018.

    REVIEW METHODS: All randomised clinical trials were included.

    RESULTS: Sixteen trials (1634 patients) were included in this meta-analysis. Incidence of delirium was not significantly lower in patients who received melatonin, with an odd ratio, OR (95%Cl) of 0.55 (0.24-1.26); ρ = 0.16, certainty of evidence = low, trial sequential analysis = inconclusive. However, patients who randomised to melatonin had a significantly shorter length of stay in intensive care units, with a mean difference, MD (95%CI) of -1.84 days (-2.46, -1.21); ρ delirium of hospitalised patients. We identified high heterogeneity across all the included trials and low certainty of evidence with potential type II error. Future multi-centre, adequately powered randomised controlled trials are warranted to provide more certainty on the use of melatonin for the prevention of delirium.

    AIMS AND OBJECTIVES: To assess intensive care unit nurses' knowledge of intensive care unit delirium and delirium assessment before and after an educational intervention. In addition, nurses' perception on the usefulness of a delirium assessment tool and barriers against delirium assessment were assessed as secondary objectives.

    BACKGROUND: Early identification of delirium in intensive care units is crucial for patient care. Hence, nurses require adequate knowledge to enable appropriate evaluation of delirium using standardised practice and assessment tools.

    DESIGN: This study, performed in Malaysia, used a single-group pretest-posttest study design to assess the effect of educational interventions and hands-on practices on nurses' knowledge of intensive care unit delirium and delirium assessment.

    METHODS: Sixty-one nurses participated in educational intervention sessions, including classroom learning, demonstrations and hands-on practices on the Confusion Assessment Method-Intensive Care Unit. Data were collected using self-administered questionnaires for the pre- and postintervention assessments. Analysis to determine the effect of the educational intervention consisted of the repeated-measures analysis of covariance.

    RESULTS: There were significant differences in the knowledge scores pre- and postintervention, after controlling for demographic characteristics. The two most common perceived barriers to the adoption of the intensive care unit delirium assessment tool were "physicians did not use nurses' delirium assessment in decision-making" and "difficult to interpret delirium in intubated patients".

    CONCLUSIONS: Educational intervention and hands-on practices increased nurses' knowledge of delirium assessment. Teaching and interprofessional involvements are essential for a successful implementation of intensive care unit delirium assessment practice.

    RELEVANCE TO CLINICAL PRACTICE: This study supports existing evidences, indicating that education and training could increase nurses' knowledge of delirium and delirium assessment. Improving nurses' knowledge could potentially lead to better delirium management practice and improve ICU patient care. Thus, continuous efforts to improve and sustain nurses' knowledge become relevant in ICU settings.

    Introduction: A geriatric syndrome is a group of signs and symptoms that occur in older people and do not fit into a discrete disease. Several medications were reported to be associated with the incidence of geriatric syndromes.

    Objective: The objective of this study was to investigate the prevalence and pattern of medications associated with geriatric syndromes (MAGSs) among the discharged elderly patients (≥65 years old).

    Materials and Methods: This is a cross-sectional study that was conducted at a Malaysian teaching hospital from October to December 2018. The discharge medications of geriatric patients were reviewed to identify MAGSs using Beers criteria, Lexicomp drug information handbook, and the United States Food and Drug Administration (USFDA) drug inserts. Chi-square test was used to compare MAGS prescribed between categories. Spearman's rank-order correlation was used to test the correlation between the presence of MAGS and the number of discharge medications. A binomial logistic regression was applied to determine the predictors of prescribing MAGSs.

    Results: A total of 400 patients (mean ± standard deviation [SD] age, 72.0 ± 5.0 years) were included, and 45.3% of them were females. The most common diseases were hypertension followed by diabetes mellitus. The mean ± SD number of discharge medications per patient was 4.2 ± 2.5. The MAGSs were prescribed in 51.7% of the patients, and 54 patients were discharged with more than one MAGSs. The most commonly prescribed MAGSs were opioid analgesics, vasodilators, and β-blockers, which are associated with falls, depression, and delirium. Polypharmacy was found in 138 patients, and it was significantly associated with the presence of MAGSs (P < 0.001). No significant differences were found in prescribing MAGSs based on the patients' gender, race, and age.

    Conclusion: The prescribing of MAGSs occurred in half of the discharged elderly patients. Physicians should be aware of the medications that are associated with special side effects in the elderly patients, and should switch to safer alternatives when possible.

    Optimal pharmacological management during extracorporeal membrane oxygenation (ECMO) involves more than administering drugs to reverse underlying disease. ECMO is a complex therapy that should be administered in a goal-directed manner to achieve therapeutic endpoints that allow reversal of disease and ECMO wean, minimisation of complications (treatment of complications when they do occur), early interruption of sedation and rehabilitation, maximising patient comfort and minimising risks of delirium. ECMO can alter both the pharmacokinetics (PK) and pharmacodynamics (PD) of administered drugs and our understanding of these alterations is still evolving. Based on available data it appears that modern ECMO circuitry probably has a less significant impact on PK when compared with critical illness itself. However, these findings need further confirmation in clinical population PK studies and such studies are underway. The altered PD associated with ECMO is less understood and more research is indicated. Until robust dosing guidelines become available, clinicians will have to rely on the principles of drug dosing in critically ill and known PK alterations induced by ECMO itself. This article summarises the PK alterations and makes preliminary recommendations on possible dosing approaches.

    Introduction: Ventilator-associated pneumonia (VAP) is defined as pneumonia that occurs 48-72 hours or there-after following endotracheal intubation. VAP increased health care costs due to hospital length of stay. Since VAP can be prevented, this study underscores the importance of identifying the current knowledge and practice on the prevention of VAP among the ICU nurses in Queen Elizabeth Hospital 2 (QEH2). The objective of this study is to determine the nurse’s knowledge and practice towards VAP prevention. Methods: The methodology used for this study is a cross-sectional study to evaluate nurses’ knowledge and practice in the ICU, QEH2. 82 ICU QEH2 nurs-es participated. Data were collected using a modified structured questionnaire based on the checklist of VAP data elements. The elements covered in the questionnaire consist of three parts, which are Part A on socio-demographic information, Part B on knowledge ventilator-associated pneumonia events and Part C on nurse’s prevention practice on ventilator-associated events. The data was analyzed using SPSS version 20. Results: The overall results of this study are 45.1% of the nurses were less knowledgeable on VAP prevention and this could lead to a prevalence of VAP in the unit. VAP is a new concept implemented in 2013, meaning that 48.53% (n=33) nurses who trained 2-5 years ago may have not covered VAP in their infection prevention and control training. Most of the ICU nurses did not profoundly practices on subglottic suction (35/82), hand hygiene prior suctioning (40/82), hand hygiene after ETT suction (16/82) and delirium risk assessment (1/82). As a discussion, this could mean the ICU nurses do not have adequate knowledge and practice awareness on VAP prevention. Conclusion: For the conclusion of this study, the nurses working in ICU, QEH2 practiced most of the recommended VAP prevention but not all. Continuous training on prevention for VAP in ICU needs to be review. The hospital management to ensure the availability of the facilities needed and the adoption of guidelines based on evidence-based practice.

    Alcohol-induced psychotic disorder (AIPD) is a rare complication of alcohol
    abuse which is characterized by an acute onset of auditory or visual
    hallucinations that occur either during or after a period of heavy alcohol
    consumption. Other symptoms include delusions, thought disorder,
    psychomotor disturbances, and abnormal affect. To establish the diagnosis,
    one must rule out other disorders such as alcohol withdrawal delirium or
    other psychotic disorders. Although it is well recognised, relatively little is
    known about the condition. Moreover, the pathogenesis and treatment of
    AIPD are still unclear despite high co-morbidity with other psychiatric
    disorders, high re-hospitalization as well as mortality rates and suicidal
    behaviour. Therefore, the prognosis appears less favourable. We present a
    case of young man with AIPD with suicidal attempt secondary to auditory
    hallucination.

    Neuropsychiatric symptoms are symptoms that caused by organic brain
    disorders. Multiple neuropsychiatric symptoms can occur concurrently in the
    course of brain related organic disorders. Two main components of
    neuropsychiatric symptoms are cognitive impairment and disturbance of
    consciousness while other neuropsychiatric symptoms, such as hallucinations,
    delusions, mood disorders, anxiety, apathy, behavioural and personality
    changes also commonly occur. Some of the mild neuropsychiatric symptoms
    could possibly be the earliest manifestations of brain related organic
    disorders. Clinicians should carefully evaluate organic factors in the
    treatment of psychosis, especially in patients of very young age or older age.
    They should have enough knowledge and experience in the integrating
    neuroscience, that is, neuropsychiatry. The present report illustrates a case of
    organic disorder with neuropsychiatric manifestations. It is about a young
    male patient who was diagnosed with anti-NMDA receptor encephalitis and
    subsequently developed acute delirium secondary to the illness.

    Delirium in the elderly is a challenging and under-recognized problem in the community. Early detection and management improves outcomes and quality of life for the elders with delirium at home.1 Family physicians (FP) play a key role in the assessments, early identification, and management of delirium and in the support and education of patients and their family caregivers.1 Clinical analysis of this case illustrates the bio-psychosocial spiritual model of approach to management of delirium in an elderly patient in the home setting.

    BACKGROUND AND OBJECTIVES: One year after the onset of the coronavirus disease 2019 (COVID-19) pandemic, we aimed to summarize the frequency of neurologic manifestations reported in patients with COVID-19 and to investigate the association of these manifestations with disease severity and mortality.

    METHODS: We searched PubMed, Medline, Cochrane library, ClinicalTrials.gov, and EMBASE for studies from December 31, 2019, to December 15, 2020, enrolling consecutive patients with COVID-19 presenting with neurologic manifestations. Risk of bias was examined with the Joanna Briggs Institute scale. A random-effects meta-analysis was performed, and pooled prevalence and 95% confidence intervals (CIs) were calculated for neurologic manifestations. Odds ratio (ORs) and 95% CIs were calculated to determine the association of neurologic manifestations with disease severity and mortality. Presence of heterogeneity was assessed with I 2, meta-regression, and subgroup analyses. Statistical analyses were conducted in R version 3.6.2.

    RESULTS: Of 2,455 citations, 350 studies were included in this review, providing data on 145,721 patients with COVID-19, 89% of whom were hospitalized. Forty-one neurologic manifestations (24 symptoms and 17 diagnoses) were identified. Pooled prevalence of the most common neurologic symptoms included fatigue (32%), myalgia (20%), taste impairment (21%), smell impairment (19%), and headache (13%). A low risk of bias was observed in 85% of studies; studies with higher risk of bias yielded higher prevalence estimates. Stroke was the most common neurologic diagnosis (pooled prevalence 2%). In patients with COVID-19 ≥60 years of age, the pooled prevalence of acute confusion/delirium was 34%, and the presence of any neurologic manifestations in this age group was associated with mortality (OR 1.80, 95% CI 1.11-2.91).

    DISCUSSION: Up to one-third of patients with COVID-19 analyzed in this review experienced at least 1 neurologic manifestation. One in 50 patients experienced stroke. In those >60 years of age, more than one-third had acute confusion/delirium; the presence of neurologic manifestations in this group was associated with nearly a doubling of mortality. Results must be interpreted with the limitations of observational studies and associated bias in mind.

    BACKGROUND: Ketamine is believed to reduce the incidence of emergence agitation in children undergoing surgery or procedure. However, recent randomized controlled trials reported conflicting findings.

    AIMS: To investigate the effect of ketamine on emergence agitation in children.

    METHODS: Databases of MEDLINE, EMBASE, and CENTRAL were systematically searched from their start date until February 2019. Randomized controlled trials comparing intravenous ketamine and placebo in children were sought. The primary outcome was the incidence of emergence agitation. Secondary outcomes included postoperative pain score, duration of discharge time, and the adverse effects associated with the use of ketamine, namely postoperative nausea and vomiting, desaturation, and laryngospasm.

    RESULTS: Thirteen studies (1125 patients) were included in the quantitative meta-analysis. The incidence of emergence agitation was 14.7% in the ketamine group and 33.3% in the placebo group. Children receiving ketamine had a lower incidence of emergence agitation, with an odds ratio being 0.23 (95% confidence interval: 0.11 to 0.46), certainty of evidence: low. In comparison with the placebo, ketamine group achieved a lower postoperative pain score (odds ratio: -2.42, 95% confidence interval: -4.23 to -0.62, certainty of evidence: very low) and lower pediatric anesthesia emergence delirium scale at 5 minutes after operation (odds ratio: -3.99, 95% confidence interval: -5.03 to -2.95; certainty of evidence: moderate). However, no evidence was observed in terms of incidence of postoperative nausea and vomiting, desaturation, and laryngospasm.

    CONCLUSION: In this meta-analysis of 13 randomized controlled trials, high degree of heterogeneity and low certainty of evidence limit the recommendations of ketamine for the prevention of emergence agitation in children undergoing surgery or imaging procedures. However, the use of ketamine is well-tolerated without any notable adverse effects across all the included trials.
