OBJECTIVE: To explore the relationship between serum sodium level and the risk of delirium in patients with sepsis. METHODS: Based on the Medical Information Mart for Intensive Care-IV (MIMIC-IV), adult patients with sepsis in the intensive care unit (ICU) were enrolled. The serum sodium level prior to the onset of sepsis during hospitalization was used as the exposure variable. Delirium was assessed using the ICU-confusion assessment method (ICU-CAM) as the primary outcome. Patients were divided into delirium and non-delirium groups based on the occurrence of delirium. The relationship between serum sodium level and delirium risk was described using restricted cubic spline (RCS) to determine the optimal reference range for serum sodium. Logistic regression analysis was used to evaluate the effect of blood sodium levels on delirium in sepsis patients. Subgroup analyses were performed to explore potential interactions and further validate the robustness of the results. Receiver operator characteristic curve (ROC curve) analysis was performed to assess the predictive value of serum sodium level for delirium occurrence in patients with sepsis. RESULTS: A total of 13 889 patients with sepsis were included, of which 4 831 experienced delirium. The maximum and mean serum sodium values were significantly higher in the delirium group compared to the non-delirium group, while there were no statistically significant differences in terms of initial and minimum serum sodium values between the two groups. Compared with the non-delirium group, the delirium group had a higher mortality and longer hospital stay. The RCS curve showed that a "U"-shaped relationship between serum sodium level and delirium risk in patients with sepsis, with the optimal reference range for average serum sodium was 135.3-141.3 mmol/L. Group based on this reference range, compared to the group with 135.3 mmol/L ≤ serum sodium ≤ 141.3 mmol/L, the delirium incidence and mortality were significantly higher, and the hospital stay was longer in the groups with serum sodium < 135.3 mmol/L and serum sodium ≥ 141.3 mmol/L [delirium incidence: 36.92%, 40.88% vs. 31.22%; 28-day mortality: 23.08%, 20.15% vs. 13.39%; 90-day mortality: 30.75%, 24.81% vs. 18.26%; in-hospital mortality: 19.53%, 17.48% vs. 11.61%; ICU mortality: 14.35%, 14.05% vs. 9.00%; hospital length of stay (days): 10.1 (6.1, 17.7), 9.4 (5.4, 17.0) vs. 8.9 (5.5, 15.4), length of ICU stay (days): 3.7 (2.1, 7.1), 4.0 (2.1, 8.9) vs. 3.2 (1.9, 6.8); all P < 0.01]. Logistic regression analysis showed that, in the initial model and each factor-adjusted models, compared to the reference group with 135.3 mmol/L ≤ serum sodium < 141.3 mmol/L, serum sodium < 135.3 mmol/L increased the risk of delirium in septic patients by 21% to 29% [odds ratio (OR) was 1.21-1.29, all P < 0.01], while serum sodium ≥ 141.3 mmol/L increased the delirium risk by 28%-52% (OR was 1.28-1.52, all P < 0.01). Subgroup analyses based on gender, age, race, diuretic use, and sequential organ failure assessment (SOFA) score revealed there was no significant interactions between subgroup variables and serum sodium, and the results supported that both serum sodium < 135.3 mmol/L and serum sodium ≥ 141.3 mmol/L were risk factors for delirium in septic patients. ROC curve analysis showed that the area under the curve (AUC) for predicting delirium in septic patients based on serum sodium was 0.614, with a cut-off value of 139.5 mmol/L yielding a specificity of 67.5% and sensitivity of 50.9%. CONCLUSIONS The risk of delirium in patients with sepsis is associated with serum sodium level in a "U"-shaped manner. Both high and low serum sodium levels are associated with increased risk of delirium, higher all-cause mortality, and prolonged hospital stays in patients with sepsis. Abnormal serum sodium levels may have predictive value for sepsis-associated delirium and could serve as an early biomarker for identifying delirium in septic patients, although further validation is needed.

OBJECTIVE: To explore the effect of light music therapy on delirium in intensive care unit (ICU) patients undergoing invasive mechanical ventilation, and provide evidence-based support for clinical prevention of delirium. METHODS: A prospective randomized controlled trial was conducted. 140 patients with invasive mechanical ventilation admitted to the department of respiratory and critical care medicine of First Affiliated Hospital of Guangxi Medical University from January 2024 to January 2025 were enrolled. The patients were divided into intervention group and control group using a random number table method. The control group received routine treatment and nursing care, while the intervention group received light music therapy three times a day for 30 minutes each time for 7 consecutive days. The confusion assessment method-ICU (CAM-ICU) was used to evaluate delirium, and the incidence of delirium within 7 days was statistically analyzed. Richmond agitation-sedation score (RASS), critical care pain observation tool (CPOT) score, mechanical ventilation duration, the length of ICU stay, and ICU stay expenses were record. RESULTS: 129 cases were ultimately included, including 64 cases in the control group and 65 cases in the intervention group. There was no statistically significant difference in baseline data between the two groups, indicating comparability. The incidence of delirium in the intervention group was significantly lower than that in the control group (27.7% vs. 51.6%, χ ² = 7.687, P = 0.006). There was no significantly difference in RASS score between the two groups before enrollment (P = 0.840). After intervention, the RASS score in the intervention group significantly decreased, from 2.00 points on the 1st day of enrollment to 0.00 points on the 7th day, while the control group only decreased from 2.00 points to 1.50 points. The decreasing trend of the intervention group was more pronounced, especially on the 3rd day (P = 0.047) and the 7th day (P =0.005), with significant differences between the groups. The time effect (F = 18.929, P < 0.001), group effect (F = 6.655, P = 0.011), and time group interaction effect (F = 7.372, P < 0.001) of the two groups of RASS score were significant, suggesting that light music therapy has better timeliness and sustainability in improving patients' sedation status. There was no significantly difference in CPOT score between the two groups before enrollment (P = 0.902). After intervention, the CPOT score in the intervention group rapidly decreased from 3.00 points before enrollment to 1.00 points on the 1st day, and continued until the 7th day, while the control group showed a slower decrease from 2.50 points to 2.00 points and only dropped to 1.00 points on the 7th day. There were significant differences on 1st day and 3rd day between two groups (both P < 0.05). The time effect (F = 28.125, P < 0.001), group effect (F = 11.580, P = 0.001), and time group interaction effect (F = 4.048, P = 0.020) of the two groups of CPOT score were significant, indicating that light music therapy has better pain control, but the interaction effect is low, indicating that the impact of the intervention on the CPOT score was mainly concentrated in the early stage (1-3 days), and the long-term effect may be influenced by other factors. Compared with the control group, the intervention group showed a significant reduction in mechanical ventilation time (days: 10.57±2.94 vs. 11.95±3.74, P = 0.021) and the length of ICU stay (days: 14.91±4.37 vs. 17.53±4.83, P = 0.002). The ICU hospitalization expenses of the intervention group was slightly lower than that of the control group [ten thousand yuan: 22.431 (12.473, 28.489) vs. 29.362 (11.996, 41.389)], but the difference was not statistically significant (P = 0.086). CONCLUSIONS Light music therapy can effectively reduce the incidence of delirium in patients undergoing invasive mechanical ventilation, improve consciousness and pain perception, shorten mechanical ventilation time and hospital stay, and has significant clinical promotion value high-quality studies.

BACKGROUND

E-learning has emerged as a crucial technique that educators embrace and apply. Two effective e-learning materials are video-based learning (VBL) and e-book-based remote learning (EBRL). While several studies have proven their effectiveness, none have compared these e-learning materials, especially regarding caregivers’ knowledge of delirium, dementia, and depression (3Ds). Based on the extant literature, many caregivers are untrained and often lack the knowledge and skills to lessen the burden on delirious, demented, and depressed older adults. Hence, there is a growing need to explore how e-learning materials will address caregivers’ lack of knowledge about the 3Ds of geriatric psychiatry.

This study ascertained the effects of e-learning materials on caregivers’ knowledge about the 3Ds of geriatric psychiatry and determined significant differences within and between groups.

A three-arm, quasi-experimental study, which included 63 informal caregivers in Baguio City who met the inclusion criteria and were chosen through purposive sampling, was conducted. Data were gathered using the Delirium-related knowledge tool, the Bangladesh version of the Depression Literacy Questionnaire, and the Dementia Knowledge Assessment Tool version 2. Data collection was done face-to-face and was conducted from March to April 2023. Data were treated with descriptive and inferential statistics using means, paired t-test, one-way omnibus ANOVA, and the post hoc Scheffé’s test. Ethics approval was provided by the Saint Louis University Research Ethics Committee (SLU-REC-UG 2023-004).

All the pretest mean scores of respondents in the VBL, EBRL, and control groups increased in the posttest. Additionally, the paired t-test revealed that the VBL and EBRL materials significantly affected the caregivers’ knowledge about the 3Ds of geriatric psychiatry, evidenced by a t-statistic of -5.80 (p=0.00001) and -4.48 (p= 0.00023), respectively. Lastly, one-way ANOVA revealed that there was a statistically significant difference in mean scores between at least two groups (F(2,60) = [7.060], p=0.002). Post hoc analysis using Scheffé’s test for multiple comparisons found that the mean values significantly differed between the VBL and the waitlist control group (Scheffé=10.589), and between the EBRL and the waitlist control group (Scheffé=10.589). There was no statistically significant difference between the VBL and the EBRL groups (Scheffé=0).

This study suggests that informal caregivers in Baguio City are moderately knowledgeable about the 3Ds of geriatric psychiatry. Moreover, both VBL and EBRL materials showed effectiveness in improving caregivers’ knowledge about the 3Ds of geriatric psychiatry, highlighting the substantial equivalence of both materials. Lastly, caregivers’ knowledge about the 3Ds of geriatric psychiatry increases as they engage in e-learning materials. Thus, it is acknowledged that VBL and EBRL materials are valuable, cost-effective, and practical interventions in improving caregivers’ knowledge about the 3Ds of geriatric psychiatry.

Background: Due to the increasing number of elderly patients being referred to anesthesia for surgical procedures, there is a growing interest with regard to the incidence of postoperative delirium and its contributing factors. Objectives: The primary objective of this study is to determine the incidence of postoperative delirium in the charity elderly patients at the Philippine General Hospital (PGH). Methods: The incidence of postoperative delirium was assessed in an analytic prospective study conducted at the PGH among elderly patients undergoing elective surgeries. Through interviews and chart reviews, the collected data focused on baseline intellectual status, age, gender, ASA classification, level of education, comorbidities, vices, previous surgeries, maintenance medications, preoperative diagnostics, duration of surgery, duration of anesthesia, type of anesthetic technique, and pain scores at the recovery room and 24 hours postoperatively. Responses to the Short Portable Mental Status Questionnaire (SPMSQ), the Preoperative and Postoperative assessment forms and the Confusion Assessment Method (CAM) instrument were analyzed. Results: It was observed that there was a 2.5% incidence of postoperative delirium in the study population and among the risk factors assessed, polypharmacy and presence of moderate to severe pain scores on the first day following surgery were significant contributors in its occurrence. Conclusion In this preliminary study, the incidence of postoperative delirium as well as the significant contributing factors were described. In succeeding investigations, it is recommended to extend the observation and follow-up periods.

INTRODUCTION: Post-anaesthesia care unit (PACU) delirium affects 5%-45% of patients after surgery and is associated with postoperative delirium and increased mortality. Up to 40% of PACU delirium is preventable, but it remains under-recognised due to a lack of awareness of its diagnosis. The nursing delirium screening scale (Nu-DESC) has been validated for diagnosing PACU delirium, but is not routinely used locally. This study aimed to use Nu-DESC to establish the incidence and risk factors of PACU delirium in patients undergoing non-cardiac surgery in the surgical population. METHODS: We conducted an audit of eligible patients undergoing major surgery in three public hospitals in Singapore over 1 week. Patients were assessed for delirium 30-60 min following their arrival in PACU using Nu-DESC, with a total score of ≥2 indicative of delirium. RESULTS: A total of 478 patients were assessed. The overall incidence rate of PACU delirium was 18/478 (3.8%), and the incidence was 9/146 (6.2%) in patients aged > 65 years. Post-anaesthesia care unit delirium was more common in females, patients with malignancy and those who underwent longer operations. Logistic regression analysis showed that the use of bispectral index (P < 0.001) and the presence of malignancy (P < 0.001) were significantly associated with a higher incidence of PACU delirium. CONCLUSION In this first local study, the incidence of PACU delirium was 3.8%, increasing to 6.2% in those aged > 65 years. Understanding these risk factors will form the basis for which protocols can be established to optimise resource management and prevent long-term morbidities and mortality in PACU delirium.

BACKGROUND: Emergence delirium (ED) is a kind of delirium that occured in the immediate post-anesthesia period. Lower body temperature on post-anesthesia care unit (PACU) admission was an independent risk factor of ED. The present study was designed to investigate the association between intraoperative body temperature and ED in elderly patients undergoing non-cardiac surgery. METHODS: This study was a secondary analysis of a prospective observational study. Taking baseline body temperature as a reference, intraoperative absolute and relative temperature changes were calculated. The relative change was defined as the amplitude between intraoperative lowest/highest temperature and baseline reference. ED was assessed with the confusion assessment method for intensive care unit at 10 and 30 min after PACU admission and before PACU discharge. RESULTS: A total of 874 patients were analyzed with a mean age of 71.8 ± 5.3 years. The incidence of ED was 38.4% (336/874). When taking 36.0°C, 35.5°C, and 35.0°C as thresholds, the incidences of absolute hypothermia were 76.7% (670/874), 38.4% (336/874), and 17.5% (153/874), respectively. In multivariable logistic regression analysis, absolute hypothermia (lowest value <35.5°C) and its cumulative duration were respectively associated with an increased risk of ED after adjusting for confounders including age, education, preoperative mild cognitive impairment, American Society of Anesthesiologists grade, duration of surgery, site of surgery, and pain intensity. Relative hypothermia (decrement >1.0°C from baseline) and its cumulative duration were also associated with an increased risk of ED, respectively. When taking the relative increment >0.5°C as a threshold, the incidence of relative hyperthermia was 21.7% (190/874) and it was associated with a decreased risk of ED after adjusting above confounders. CONCLUSIONS: In the present study, we found that intraoperative hypothermia, defined as either absolute or relative hypothermia, was associated with an increased risk of ED in elderly patients after non-cardiac surgery. Relative hyperthermia, but not absolute hyperthermia, was associated with a decreased risk of ED. REGISTRATION Chinese Clinical Trial Registry (No. ChiCTR-OOC-17012734).

OBJECTIVE: To explore lumbar plexus nerve block combined with general anesthesia in elderly patients undergoing hip operation could improve analgesia effect, reduce consumption of analgesics, prevent inflammatory reaction, and avoid postoperative delirium(POD). METHODS: Totally 200 elderly patients underwent hip fracture surgery from February 2020 to September 2021 were selected and were divided into observation group and control group according to different anesthesia methods. There were 97 patients in observation group including 66 males and 33 females; aged (70.23±6.60) years old;body mass index (BMI) was (23.13±1.94) kg·m-2;19 patients with hemi arthroplasty, 46 patients with total hip arthroplasty, and 32 patients with femur intertrochanteric fixation;treated with lumbar plexus block combined with general anesthesia. There were 94 patients in control group, including 66 males and 33 females;aged (68.80±6.24) years old;BMI was (22.88±1.85) kg·m-2;14 patients with hemi arthroplasty, 39 patients with total hip arthroplasty, and 41 patients with femur intertrochanteric fixation;treated with only general anesthesia. Nine patients were separated due to the change of surgical protocol or chronic disease. The incidence of POD at 1, 2 and 3 days after surgery, mini-mental state examination (MMSE) score, visual analogue scale (VAS) in resting state, serum inflammatory factors levels [such as C-reactive protein(CRP), interleukin-1β(IL-1β), interleukin-6(IL-6), tumor necrosis factor-α(TNF-α)] at 1 d before operation, 1 and 6 h after surgery, consumption of sufentanil between two groups were compared. RESULTS: The incidences of POD in observation group were lower than control group at 1, 2 and 3 days of operation (P<0.05), MMSE score in observation group was higher than that of control group (P<0.05), VAS in observation group was lower than that of control group (P<0.01). The incidences of POD decreased and MMSE score were increaed in both groups day by day (P<0.01). The levels of CRP, IL-1β, IL-6 and TNF-α in observation group were lower than that of control group at 1 h after operation (P<0.01). The levels of CRP, IL-6 and TNF-α in observation group were lower than that of control group at 6 h after operation (P<0.01), while no statisitical difference in IL-1β between two groups(P>0.05). The consumption of sufentanil in observation group was lower than that of control group (P<0.01). CONCLUSION Compared with general anesthesia, lumbar plexus nerve block combined with general anesthesia for the operations of hip fracture in elderly patients has better analgesic effect, has advantages of slight inflammatory reaction, and could decrease consumption of opioid and incidence of POD.

OBJECTIVE: To investigate the relationship between malnutrition and delirium and its effect on prognosis in elderly patients with severe pneumonia undergoing invasive mechanical ventilation. METHODS: A prospective observational study was conducted. Patients with severe pneumonia aged ≥ 60 years old who underwent invasive mechanical ventilation admitted to department of critical care medicine of the Second People's Hospital of Lianyungang from January 2021 to December 2022 were enrolled. The confusion assessment method (CAM) was used to evaluate the delirium of the patients in intensive care unit (ICU). The score of CAM ≥ 1 was defined as delirium. Mini nutritional assessment short-form (MNA-SF) was used to assess the nutritional status of patients, and MNA-SF score ≤ 7 was defined as malnutrition. Patients were divided into delirium group and non-delirium group according to whether delirium occurred. The differences in clinical indicators, length of ICU stay, duration of mechanical ventilation and wake-up time after drug withdrawal were compared between the two groups. After 28 days of short-term follow-up, the patients were divided into death group and survival group, and the differences in the incidence of delirium and malnutrition between the two groups were compared. Binary multivariate Logistic regression analysis was used to screen the risk factors for delirium in elderly patients with severe pneumonia undergoing invasive mechanical ventilation. Kaplan-Meier survival curve was used to analyze the effect of delirium on prognosis. RESULTS: A total of 132 elderly patients with severe pneumonia undergoing invasive mechanical ventilation were enrolled, of whom 98 survived and 34 died within 28 days, with a mortality of 25.76%. The incidence of malnutrition and delirium in the death group was significantly higher than that in the survival group (61.76% vs. 37.76%, 64.71% vs. 26.53%, both P < 0.05), and the MNA-SF score was significantly lower than that in the survival group (6.32±1.80 vs. 8.72±2.23, P < 0.01). Procalcitonin (PCT), interleukin-6 (IL-6) and blood lactic acid (Lac) in the death group were significantly higher than those in the survival group [PCT (μg/L): 4.47 (2.69, 10.39) vs. 2.77 (1.28, 5.94), IL-6 (ng/L): 204.08 (126.12, 509.85) vs. 120.46 (60.67, 290.99), Lac (mmol/L): 5.14 (2.75, 8.60) vs. 3.13 (2.16, 4.30), all P < 0.05], and the wake-up time after drug withdrawal was significantly longer than that in the survival group (minutes: 33.94±8.51 vs. 28.92±7.03, P < 0.01). Among 132 elderly patients with severe pneumonia undergoing invasive mechanical ventilation, 48 patients had delirium during ICU stay, and 84 patients did not have delirium. The incidence of delirium was 36.36%. The 28-day mortality in the delirium group was significantly higher than that in the non-delirium group (45.83% vs. 14.29%, P < 0.01), and the MNA-SF score was significantly lower than that in the non-delirium group (6.46±1.77 vs. 9.05±2.15, P < 0.01), the length of ICU stay, duration of mechanical ventilation, and wake-up time after drug withdrawal were also significantly longer than those in the non-delirium group [length of ICU stay (days): 13.40±9.59 vs. 10.06±7.81, duration of mechanical ventilation (hours): 197.06±89.80 vs. 138.81±82.30, wake-up time after drug withdrawal (minutes): 35.85±7.01 vs. 26.99±6.12, all P < 0.05]. Binary multivariate Logistic regression analysis showed that malnutrition [odds ratio (OR) = 7.527, 95% confidence interval (95%CI) was 2.585-21.917], Lac (OR = 5.345, 95%CI was 1.733-16.483), wake-up time after drug withdrawal (OR = 6.653, 95%CI was 2.021-21.904) were independent risk factors for delirium during ICU stay in elderly patients with severe pneumonia undergoing invasive mechanical ventilation (all P < 0.01). Kaplan-Meier survival analysis showed that the 28-day cumulative survival rate of patients in the delirium group was significantly lower than that in the non-delirium group (54.17% vs. 85.71%), and the difference was statistically significant (Log-Rank test: χ² = 16.780, P < 0.001). CONCLUSIONS The risk factors for delirium in elderly patients with severe pneumonia undergoing invasive mechanical ventilation during ICU stay include malnutrition, Lac, and wake-up time after drug withdrawal. The occurrence of delirium is closely related to poor prognosis.

We wished to establish an expert consensus on late stage of critical care (CC) management. The panel comprised 13 experts in CC medicine. Each statement was assessed based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) principle. Then, the Delphi method was adopted by 17 experts to reassess the following 28 statements. (1) ESCAPE has evolved from a strategy of delirium management to a strategy of late stage of CC management. (2) The new version of ESCAPE is a strategy for optimizing treatment and comprehensive care of critically ill patients (CIPs) after the rescue period, including early mobilization, early rehabilitation, nutritional support, sleep management, mental assessment, cognitive-function training, emotional support, and optimizing sedation and analgesia. (3) Disease assessment to determine the starting point of early mobilization, early rehabilitation, and early enteral nutrition. (4) Early mobilization has synergistic effects upon the recovery of organ function. (5) Early functional exercise and rehabilitation are important means to promote CIP recovery, and gives them a sense of future prospects. (6) Timely start of enteral nutrition is conducive to early mobilization and early rehabilitation. (7) The spontaneous breathing test should be started as soon as possible, and a weaning plan should be selected step-by-step. (8) The waking process of CIPs should be realized in a planned and purposeful way. (9) Establishment of a sleep-wake rhythm is the key to sleep management in post-CC management. (10) The spontaneous awakening trial, spontaneous breathing trial, and sleep management should be carried out together. (11) The depth of sedation should be adjusted dynamically in the late stage of CC period. (12) Standardized sedation assessment is the premise of rational sedation. (13) Appropriate sedative drugs should be selected according to the objectives of sedation and drug characteristics. (14) A goal-directed minimization strategy for sedation should be implemented. (15) The principle of analgesia must be mastered first. (16) Subjective assessment is preferred for analgesia assessment. (17) Opioid-based analgesic strategies should be selected step-by-step according to the characteristics of different drugs. (18) There must be rational use of non-opioid analgesics and non-drug-based analgesic measures. (19) Pay attention to evaluation of the psychological status of CIPs. (20) Cognitive function in CIPs cannot be ignored. (21) Delirium management should be based on non-drug-based measures and rational use of drugs. (22) Reset treatment can be considered for severe delirium. (23) Psychological assessment should be conducted as early as possible to screen-out high-risk groups with post-traumatic stress disorder. (24) Emotional support, flexible visiting, and environment management are important components of humanistic management in the intensive care unit (ICU). (25) Emotional support from medical teams and families should be promoted through"ICU diaries"and other forms. (26) Environmental management should be carried out by enriching environmental content, limiting environmental interference, and optimizing the environmental atmosphere. (27) Reasonable promotion of flexible visitation should be done on the basis of prevention of nosocomial infection. (28) ESCAPE is an excellent project for late stage of CC management.

BACKGROUND: Emergence delirium is a state of mental confusion and agitation after wakening from anesthesia that may result in traumatic injuries to the child. Limited drugs have been studied or used to prevent this occurrence. OBJECTIVE: To determine the efficacy and safety of intravenous lidocaine in controlling emergence agitation (EA) in children undergoing surgeries done under general anesthesia compared to placebo or other intravenous anesthetics. METHODOLOGY: This study is a meta-analysis, where published articles were obtained using PubMed, Cochrane Library, Clinical Trials, and Google Scholar up to August 2022. The primary outcome measure includes incidence of emergence delirium while secondary outcomes are postoperative pain and adverse effects comparing lidocaine and other intravenous drugs. The latter includes nausea and vomiting, untoward airway events and local anesthetic toxicity (LAST). Review Manager 5.4 was used for statistical analysis. RESULTS: There were a total of 6 articles included for quantitative and qualitative analysis. The overall incidence of emergence agitation (RR=1.03, 95% CI [0.50, 2.13], P=0.94) and adverse events were higher in the Lidocaine group, although the differences were not significant. Subgroup analysis by comparator showed significant increased risk of developing EA with Lidocaine compared to other intravenous drugs (RR=2.06, 95% CI [1.32, 2.32], P=0.002). The risk for developing postoperative pain is decreased with Lidocaine compared to placebo and other drugs. CONCLUSION Intravenous lidocaine given to children undergoing general anesthesia with sevoflurane increased their risk for emergence delirium, compared to both placebo and other intravenous anesthetics.
