RESUMO
Abstract Objective: Emergence delirium is a common complication in children. Recorded mother's voice, as a non-pharmacological measure, is increasingly used to prevent the emergence of delirium in pediatric patients, but sufficient evidence is still needed to prove its efficacy. Methods: Embase, PubMed, Cochrane Library, Web of Science, CINAHL, and Sinomed databases were searched for randomized controlled trials exploring the efficacy of recorded mother's voice in preventing the emergence of delirium in pediatric patients undergoing general anesthesia. The original data were pooled for the meta-analysis with Review Manager 5.4.1. This study was conducted based on the Cochrane Review Methods. Results: Eight studies with 724 children were included in the analysis. Recorded mother's voice reduced the incidence of emergence delirium when compared with either no voice (RR: 0.45; [95 % CI, 0.34 - 0.61]; p < 0.01; I2 = 7 %) or stranger's voice (RR: 0.51; [95 % CI, 0.28 - 0.91]; p = 0.02; I2 = 38 %) without increasing other untoward reactions. In addition, it shortened the post-anesthesia care unit stay time when compared with no voice (MD = -5.64; [95 % CI, -8.43 to -2.58]; p < 0.01, I2 = 0 %), but not stranger's voice (MD = -1.23; [95 % CI, -3.08 to 0.63]; p = 0.19, I2 = 0 %). It also shortened the extubation time and reduced the incidence of postoperative rescue analgesia. Conclusion: The current analysis indicated that recorded mother's voices could reduce the incidence of emergency delirium, shorten post-anesthesia care unit stay time and extubation time, and decrease the incidence of postoperative rescue analgesia in children.

Futuros estudios deberían explorar las razones que expliquen los diferentes grados de cumplimiento por elemento del en la práctica clínica.
Introduction Implementing the ABCDEF bundle has demonstrated improved outcomes in patients with critical illness. This study aims to describe the daily compliance of the ABCDEF bundle in a Chilean intensive care unit. Methods Retrospective observational study of electronic clinical records of nursing, physiotherapy, and medical professionals who cared for patients over 18 years of age, admitted to an intensive care unit for at least 24 hours, with or without mechanical ventilation. Daily bundle compliance was determined by considering the daily records for each element: Assess pain (element A), both spontaneous awakening trials (element B1) and spontaneous breathing trials (element B2), choice of sedation (element C), delirium assessment (element D), early mobilization (element E), and family engagement (element F). Results 4165 registered bundle elements were obtained from nursing (47%), physiotherapy (44%), and physicians (7%), including 1134 patient/days (from 133 patients). Elements E and C showed 67 and 40% compliance, while D, A, and B2 showed 24, 14 and 11%, respectively. For B1 and F, 0% compliance was achieved. Compliance was higher in patients without mechanical ventilation for A and E, while it was similar for D. Conclusions Early mobilization had the highest compliance, while spontaneous awakening trials and family engagement had absolute non-compliance. Future studies should explore the reasons for the different degrees of compliance per bundle element in clinical practice.
RESUMO
@#Objective To investigate the risk factors and prevention strategies of postoperative delirium in Stanford B aortic dissection. Methods Clinical data of the patients diagnosed with Stanford B aortic dissection and undergoing endovascular aortic repair from January 2020 to August 2021 in our department were retrospectively collected. Patients were divided into a non-delirium group and a delirium group according to the presence of postoperative delirium. The risk factors for postoperative delirium after Stanford type B aortic dissection and the protective effect of dexmedetomidine on delirium were analyzed. Results A total of 659 patients with Stanford type B aortic dissection were enrolled, including 540 males and 119 females with a median age of 58.00 (41.00, 75.00) years. There were 450 patients in the non-delirium group, and 209 patients in the delirium group. There was no statistical difference in gender, body mass index, hypertension, hyperlipidemia, smoking and drinking history, cholesterol triglyceride level, or creatinine glomerular filtration rate (P＞0.05). Age was an independent risk factor for postoperative delirium in Stanford type B aortic dissection (OR=1.392, 95%CI 1.008-1.923, P=0.044). Moreover, whether dexmedetomidine was used or not had no effect on the duration of postoperative delirium (χ2=4.662, P=0.588). Conclusion Age is an independent risk factor for postoperative delirium in patients with Stanford type B aortic dissection. The incidence of postoperative delirium in young patients is lower than that in the patients with middle and elderly age, and it may be of reference value to prevent postoperative delirium. Dexmedetomidine has no significant effect on controlling the duration of postoperative delirium.

@#Objective To systematically evaluate the risk factors for postoperative delirium after surgery for Stanford type A aortic dissection. Methods We searched the CNKI, SinoMed, Wanfang data, VIP, PubMed, Web of Science, EMbase, The Cochrane Library database from inception to September 2022. Case-control studies, and cohort studies on risk factors for postoperative delirium after surgery for Stanford type A aortic dissection were collected to identify studies about the risk factors for postoperative delirium after surgery for Stanford type A aortic dissection. Quality of the included studies was evaluated by the Newcastle-Ottawa scale (NOS). The meta-analysis was performed by RevMan 5.3 software and Stata 15.0 software. Results A total of 21 studies were included involving 3385 patients. The NOS score was 7-8 points. The results of meta-analysis showed that age (MD=2.58, 95%CI 1.44 to 3.72, P＜0.000 01), male (OR=1.33, 95%CI 1.12 to 1.59, P=0.001), drinking history (OR=1.45, 95%CI 1.04 to 2.04, P=0.03), diabetes history (OR=1.44, 95%CI 1.12 to 1.85, P=0.005), preoperative leukocytes (MD=1.17, 95%CI 0.57 to 1.77), P=0.000 1), operation time (MD=21.82, 95%CI 5.84 to 37.80, P=0.007), deep hypothermic circulatory arrest (DHCA) time (MD=3.02, 95%CI 1.04 to 5.01, P=0.003), aortic occlusion time (MD=8.94, 95%CI 2.91 to 14.97, P=0.004), cardiopulmonary bypass time (MD=13.92, 95%CI 5.92 to 21.91, P=0.0006), ICU stay (MD=2.77, 95%CI 1.55 to 3.99, P＜0.000 01), hospital stay (MD=3.46, 95%CI 2.03 to 4.89, P＜0.0001), APACHEⅡ score (MD=2.76, 95%CI 1.59 to 3.93, P＜0.000 01), ventilation support time (MD=6.10, 95%CI 3.48 to 8.72, P＜0.000 01), hypoxemia (OR=2.32, 95%CI 1.40 to 3.82, P=0.001), the minimum postoperative oxygenation index (MD=−79.52, 95%CI −125.80 to −33.24, P=0.000 8), blood oxygen saturation (MD=−3.50, 95%CI −4.49 to −2.51, P＜0.000 01), postoperative hemoglobin (MD=−6.35, 95%CI −9.21 to −3.50, P＜0.000 1), postoperative blood lactate (MD=0.45, 95%CI 0.15 to 0.75, P=0.004), postoperative electrolyte abnormalities (OR=5.94, 95%CI 3.50 to 10.09, P＜0.000 01), acute kidney injury (OR=1.92, 95%CI 1.34 to 2.75, P=0.000 4) and postoperative body temperature (MD=0.79, 95%CI 0.69 to 0.88, P＜0.000 01) were associated with postoperative delirium after surgery for Stanford type A aortic dissection. Conclusion The current evidence shows that age, male, drinking history, diabetes history, operation time, DHCA time, aortic occlusion time, cardiopulmonary bypass time, ICU stay, hospital stay, APACHEⅡ score, ventilation support time, hypoxemia and postoperative body temperature are risk factors for the postoperative delirium after surgery for Stanford type A aortic dissection. Oxygenation index, oxygen saturation, and hemoglobin number are protective factors for delirium after Stanford type A aortic dissection.
RESUMO
ABSTRACT Introduction: Goal-directed fluid therapy (GDFT) has been shown to reduce postoperative complications. The feasibility of GDFT in transcatheter aortic valve replacement (TAVR) patients under general anesthesia has not yet been demonstrated. We examined whether GDFT could be applied in patients undergoing TAVR in general anesthesia and its impact on outcomes. Methods: Forty consecutive TAVR patients in the prospective intervention group with GDFT were compared to 40 retrospective TAVR patients without GDFT. Inclusion criteria were age ≥ 18 years, elective TAVR in general anesthesia, no participation in another interventional study. Exclusion criteria were lack of ability to consent study participation, pregnant or nursing patients, emergency procedures, preinterventional decubitus, tissue and/or extremity ischemia, peripheral arterial occlusive disease grade IV, atrial fibrillation or other severe heart rhythm disorder, necessity of usage of intra-aortic balloon pump. Stroke volume and stroke volume variation were determined with uncalibrated pulse contour analysis and optimized according to a predefined algorithm using 250 ml of hydroxyethyl starch. Results: Stroke volume could be increased by applying GDFT. The intervention group received more colloids and fewer crystalloids than control group. Total volume replacement did not differ. The incidence of overall complications as well as intensive care unit and hospital length of stay were comparable between both groups. GDFT was associated with a reduced incidence of delirium. Duration of anesthesia was shorter in the intervention group. Duration of the interventional procedure did not differ. Conclusion: GDFT in the intervention group was associated with a reduced incidence of postinterventional delirium.
RESUMO
ABSTRACT BACKGROUND AND OBJECTIVES: Bone fractures constitute a frequent cause of emergency care in the pediatric population. Opioid drugs are routinely used for analgesia during the hospitalization of children victims of trauma. Few studies have evaluated the importance of a multimodal approach to analgesia in this context. The aim of this study was to compare the analgesic effect and possible side effects of fentanyl compared to those of ketamine. METHODS: The study analyzed 50 children and adolescents, aged between 24 and 192 months, submitted to surgical treatment of upper limb fractures in a tertiary trauma care hospital. The participants were randomized into two groups: one that received Ketamine and the other Fentanyl. In the post-anesthetic recovery room (PARR), pain intensity and the occurrence of delirium were measured for a period of 30 minutes. The incidence of respiratory depression, nausea, vomiting and other side effects during the surgical procedure were assessed. RESULTS: The sample consisted mostly of male individuals (76.0%). The mean age of the participants was 90.1 months. The use of a low-flow oxygen cannula was necessary in 30.0% of the participants. The incidence of vomiting and laryngospasm was 2.0% among the participants, and 6.0% presented increased salivary secretion. The occurrence of pain, delirium and respiratory depression was not different between the two assessed groups, as well as the occurrence of nausea and laryngospasm. CONCLUSION: Ketamine is not an effective and safe option to opioids for analgesia in children undergoing surgical procedures to treat upper limb fractures.
RESUMO JUSTIFICATIVA E OBJETIVOS: As fraturas ósseas constituem causa frequente de atendimento de emergência na população pediátrica. Fármacos opioides são rotineiramente utilizados para analgesia durante a hospitalização de crianças vítimas de trauma. Poucos estudos avaliaram a importância de uma abordagem multimodal para analgesia nesse contexto. O objetivo deste estudo foi comparar o efeito analgésico e possíveis efeitos adversos do fentanil em relação aos da cetamina. MÉTODOS: Foram analisados 50 crianças e adolescentes, com idade entre 24 e 192 meses, submetidos ao tratamento cirúrgico das fraturas de membros superiores em um hospital terciário de atendimento ao trauma. Os participantes foram aleatorizados em dois grupos: um recebeu cetamina e outro fentanil. Na sala de recuperação pós-anestésica (SRPA), a intensidade da dor e a ocorrência de delirium foram mensuradas por um período de 30 minutos. A incidência de depressão respiratória, náuseas, vômitos e outros efeitos adversos durante o procedimento cirúrgico foram avaliados. RESULTADOS: A amostra foi composta, em sua maioria, por indivíduos do sexo masculino (76,0%). A média de idade dos participantes foi de 90,1 meses. O uso de cânula de oxigênio de baixo fluxo foi necessário em 30,0% dos participantes. A incidência de vômitos e laringoespasmo foi de 2,0% entre os participantes, sendo que 6,0% apresentaram aumento da secreção salivar. A ocorrência de dor, delirium e depressão respiratória não foi diferente entre os dois grupos avaliados, assim como a ocorrência de náuseas e laringoespasmo. CONCLUSAO: Acetamina não se mostrou uma opção eficaz e segura aos opioides para analgesia em crianças submetidas a procedimentos cirúrgicos para tratamento de fraturas de membros superiores.
RESUMO
Abstract Background: Emergence Delirium (ED) is an essential condition in the immediate postoperative period. Systematic review and meta-analysis of randomized controlled trials have concluded that the effect of ketamine on postoperative delirium remains unclear. The present study sought to evaluate if the intraoperative use of ketamine for postoperative analgesia is associated with postoperative ED in laparoscopic surgeries. Methods: A prospective observational study was performed in the PostAnesthetic Care Unit (PACU) to evaluate patients who had undergone laparoscopic surgery under a rigid intraoperative anesthesia protocol from July 2018 to January 2019. Patients submitted to laparoscopic surgery for cholecystectomy, oophorectomy, or salpingectomy with a score ≥1 on the Richmond Assessment Sedation Scale (RASS) or ≥2 on the Nursing Delirium Screening Scale (Nu-DESC) were considered to have ED. t-test, Chi-Square test or Fisher's exact tests were used for comparison. Results: One hundred and fifteen patients were studied after laparoscopic surgery. Seventeen patients (14.8%) developed ED, and the incidence of ED in patients who received ketamine was not different from that of other patients (18.3% vs. 10.6%, p = 0.262). Patients with ED had more postoperative pain and morphine requirement at the PACU (p = 0.005 and p = 0.025, respectively). Type of surgery (general surgery, OR = 6.4, 95% CI 1.2‒35.2) and postoperative pain (OR = 3.7, 95% CI 1.2‒11.4) were risk factors for ED. Conclusion: In this study, no association was found between ED and intraoperative administration of ketamine in laparoscopic surgeries. Type of surgery and postoperative pain were risk factors for ED.
RESUMO
ABSTRACT Objective: To determine whether enteral melatonin decreases the incidence of delirium in critically ill adults. Methods: In this randomized controlled trial, adults were admitted to the intensive care unit and received either usual standard care alone (Control Group) or in combination with 3mg of enteral melatonin once a day at 9 PM (Melatonin Group). Concealment of allocation was done by serially numbered opaque sealed envelopes. The intensivist assessing delirium and the investigator performing the data analysis were blinded to the group allocation. The primary outcome was the incidence of delirium within 24 hours of the intensive care unit stay. The secondary outcomes were the incidence of delirium on Days 3 and 7, intensive care unit mortality, length of intensive care unit stay, duration of mechanical ventilation and Glasgow outcome score (at discharge). Results: We included 108 patients in the final analysis, with 54 patients in each group. At 24 hours of intensive care unit stay, there was no difference in the incidence of delirium between Melatonin and Control Groups (29.6 versus 46.2%; RR = 0.6; 95%CI 0.38 - 1.05; p = 0.11). No secondary outcome showed a statistically significant difference. Conclusion: Enteral melatonin 3mg is not more effective at decreasing the incidence of delirium than standard care is in critically ill adults.
RESUMO Objetivo: Determinar se a melatonina enteral diminui a incidência de delirium em adultos em estado grave. Métodos: Neste estudo controlado e randomizado, os adultos foram admitidos à unidade de terapia intensiva e/ou receberam apenas o padrão de cuidado habitual (Grupo Controle) ou o tratamento combinado com 3mg de melatonina enteral uma vez ao dia às 21h (Grupo Melatonina). A ocultação da alocação foi feita por meio de envelopes selados opacos e numerados sequencialmente. O intensivista que avaliou o delirium e o pesquisador que realizou a análise dos dados foram cegados quanto à alocação do grupo. O desfecho primário foi a incidência de delirium dentro de 24 horas de internação na unidade de terapia intensiva. Os desfechos secundários foram a incidência de delirium nos dias 3 e 7, a mortalidade na unidade de terapia intensiva, a duração da internação na unidade de terapia intensiva, a duração da ventilação mecânica e o escore da escala de desfecho de Glasgow (na alta). Resultados: Foram incluídos 108 pacientes na análise final, com 54 sujeitos em cada grupo. Em 24 horas de internação na unidade de terapia intensiva, a incidência de delirium não foi diferente entre os Grupos Melatonina e Controle (29,6% versus 46,2%; RR = 0,6; IC95% 0,38 - 1,05; p = 0,11). Nenhum desfecho secundário apresentou diferenças estatisticamente significativas. Conclusão: Em adultos em estado grave, 3mg de melatonina enteral não foi mais eficaz que os cuidados padrão na redução da incidência de delirium.
RESUMO
Abstract Background: Most cardiac surgery patients experience postoperative anemia. Delirium and Atrial Fibrillation (AF) are common and independent predictors of morbidity and mortality. Few reports examine their association with postoperative anemia. This study aims to quantify the association between anemia and these outcomes in patients undergoing cardiac surgery. Methods: This post-hoc analysis of the DECADE randomized controlled trial ran at six academic US hospitals. Patients aged 18-85 years with heart rate > 50 bpm undergoing cardiac surgery who had daily hemoglobin measurements in the first 5 Postoperative Days (POD) were included. Delirium was assessed twice daily with the Confusion Assessment Method for the ICU (CAM - ICU), preceded by the Richmond Agitation and Sedation Scale, with patients excluded from assessment if sedated. Patients had daily hemoglobin measurements, continuous cardiac monitoring plus twice-daily 12-lead electrocardiograms, up to POD4. AF was diagnosed by clinicians blinded to hemoglobin levels. Results: Five hundred and eighty-five patients were included. Mean postoperative hemoglobin Hazard Ratio (HR): 0.99 (95% CI 0.83, 1.19; p = 0.94) per 1 g.dL-1 hemoglobin decrease. 197 (34%) developed AF, mainly on POD = 2.3. Estimated HR = 1.04 (95% CI 0.93, 1.17; p = 0.51) per 1 g.dL-1 hemoglobin decrease. Conclusions: Most patients undergoing major cardiac surgery were anemic in the postoperative phase. AF and delirium occurred in 34% and 12% of patients, respectively, but neither were significantly correlated with postoperative hemoglobin.
RESUMO
ABSTRACT This report aims to present an elderly woman with persistent delirium after hospitalization for lethargy secondary to hyponatremia. The diagnosis of pontine myelinolysis was made and there were no characteristic neurological manifestations such as pupillary changes or spastic tetraparesis. Hallucinations and personality changes were the clues to the diagnosis and should be considered an atypical manifestation of pontine myelinolysis.
RESUMO O objetivo deste relato é apresentar uma idosa que apresentou, após internação por letargia secundária à hiponatremia, delirium persistente depois da alta hospitalar. O diagnóstico de mielinólise pontina foi feito após a alta hospitalar e não houve manifestações neurológicas características, como alterações pupilares ou tetraparesia espástica. Alucinações e mudança de personalidade foram as pistas para o diagnóstico e devem ser consideradas como uma manifestação atípica de mielinólise pontina.
RESUMO
Objective:To evaluate the relationship between the severity of preoperative brain injury and postoperative delirium (POD) in elderly patients using latent class analysis based on markers of brain injury.Methods:One hundred and thirty-one American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ patients, aged 65-84 yr, with a body mass index of 18-28 kg/m 2, scheduled for elective unilateral total hip arthroplasty in our hospital, were selected. Cognitive function was assessed using the Mini-Mental State Examination before surgery. Arterial blood samples were collected before anesthesia to measure the plasma concentrations of brain-derived neurotrophic factor, inducible nitric oxide synthase, prostaglandin E2, central nervous system-specific protein (S100β), glial fibrillary acidic protein, neurofilament light chain, matrix metalloproteinase-9, fibroblast growth factor 23, complement 3, complement 3a, complement 5a and irisin using enzyme-linked immunosorbent assay. POD was evaluated using the Confusion Assessment Method within 3 days after operation, and the patients were divided into POD group and non-POD group. The patients were divided into different injury severity subtypes based on the levels of brain injury markers using latent class analysis, and logistic multivariate regression was used to analyze the independent risk factors for POD. Results:Compared with non-POD group, the concentrations of neurofilament light chain, glial fibrillary acidic protein, S100β and prostaglandin E2 were significantly different in POD group ( P<0.05). Using these four brain injury markers for latent class analysis, patients were divided into a high severity of brain injury group (91.51%) and a low severity of brain injury group (8.49%). The results of logistic multivariate regression analysis showed that subtypes of brain injury ( OR=8.31, 95% confidence interval [ CI] 1.77-38.90, P=0.007), age ( OR=1.14, 95% CI 1.03-1.24, P=0.007), and plasma irisin concentrations ( OR=0.99, 95% CI 0.98-0.99, P=0.027) were independent risk factors for POD. Conclusions:Higher severity of preoperative brain injury is an independent risk factor for POD in elderly patients.
RESUMO
Objective:To evaluate the relationship between preoperative serum bilirubin concentrations and postoperative delirium (POD) in the patients undergoing knee or hip replacement.Methods:Medical records from 413 patients undergoing knee or hip arthroplasty were selected from August 2020 to October 2023 at Qingdao Municipal Hospital using a nested case-control design based on the PNDABLE study cohort. The patients were divided into POD group ( n=77) and non-POD group ( n=336) according to whether POD occurred. Univariate analysis was used to analyze the influencing factors. Logistic regression was used to identify the risk factors for POD. The significance of mediation effect was tested. The receiver operating characteristic curve was drawn to evaluate the accuracy of risk factors in predicting POD. Results:There were significant differences in age, education time, ratio of diabetes history, Memorial Delirium Assessment Scale score, total bilirubin concentration, direct bilirubin concentration, indirect bilirubin concentration, Aβ 42 concentration, p-tau concentration, t-tau concentration, Aβ 42/p-tau ratio and Aβ 42/t-tau ratio between POD group and non-POD group ( P<0.05). The results of logistic regression analysis showed that preoperative serum total bilirubin, direct bilirubin and indirect bilirubin were risk factors for POD ( P<0.05). The results of mediation effects showed that the concentration of total tau protein in CSF partly mediated the relationship between high serum total bilirubin, direct bilirubin and indirect bilirubin concentrations and POD. The area under the receiver operating characteristic curve of total bilirubin, direct bilirubin and indirect bilirubin combined with CSF biomarker concentrations in predicting POD was 0.83 ( P<0.001). Conclusions:Preoperative elevated concentrations of total bilirubin, direct bilirubin and indirect bilirubin are risk factors for POD in the patients undergoing knee or hip replacement. CSF t-tau concentration has a partly mediating role in the association between serum total bilirubin, direct bilirubin and indirect bilirubin concentrations and the development of POD.
RESUMO
Objective To construct a risk assessment scale for postoperative delirium(POD)in elderly patients undergoing hip and knee joint replacement and evaluate the effect.Methods A total of 474 elderly patients undergoing hip and knee arthroplasty from March 2021 to May 2022 were collected as the training set,and a total of 153 the homogeneous patients from January 2022 to May 2022 were collected as the validation set.The patients were divided into two groups based on whether or not POD occurred:non-POD group and POD group.Risk factors of POD in the training set were analyzed by univariate analysis and multifactorial logistic regression.The consistency of the model was evaluated by Homser-Lemeshow goodness of fit test.The postoperative delirium risk assessment scale was established after the selected variables as-signed value according to OR value,and the predictive efficacy of the scale was evaluated by receiver oper-ating characteristic(ROC)curve.The patients in the training set and the validation set were divided into two groups according to the cut-off value:high-risk and low-risk.The incidence rate of POD with different risk stratification was calculated and the applicability of the risk assessment scale was evaluated.Results Fifty-eight patients(12.2%)with POD in the training set,and nineteen patients(12.4%)with POD in the validation set.Multifactor logistic regression showed that age≥85 years,ASA physical status Ⅲ or Ⅳ,the mini-mental state examination(MMSE)score≤24 points,preoperative sleep disorder,comorbid neu-rological disorders,use of general anesthesia,and non-use of dexmedetomidine were independent risk factors of POD.The POD risk assessment scale was then published based the seven risk factors.The ROC curve showed that the area under the curve(AUC)for this scale to predict the risk of POD was 0.956(95%CI 0.937-0.975),and the risk stratification was performed with a cut-off value of 44.5 points,which divided the patients into low-risk and high-risk.Compared with low-risk,the incidence rate of POD in high-risk patients group was significantly increased(P＜0.001).Conclusion A risk assessment scale based on the seven risk factors:age≥85 years,ASA physical status Ⅲ or Ⅳ,MMSE score≤24 points,preoperative sleep disorder,combined neurological disease,use of general anesthetic modality,and non-use of dexmedetomidine,can effectively identify elderly patients undergoing hip and knee replacement who are at high risk of developing POD.
RESUMO
Objective To investigate the effect of preoperative oral midazolam on postoperative de-lirium in elderly patients with preoperative moderate-severe anxiety undergoing radical resection of colorectal cancer.Methods Eighty elderly patients undergoing laparoscopic surgery for radical resection of colorectal cancer,32 males and 48 females,aged 65-79 years,BMI 21-27 kg/m2,ASA physical status Ⅱ or Ⅲ,the state-trait anxiety inventory(STAI-S)≥38 scores at admission were selected.Patients were divided into two groups using random number method:control group and midazolam group,40 patients in each group.The midazolam group were administrated midazolam 7.5 mg per night till one day before surgery,while the placebo was administrated in the control group.The incidence of delirium 3 days after surgery and the STAI-S scores of one day before surgery were evaluated.The HR and MAP at entry,30 minutes after an-esthesia induction,1 hour,2 hours after anesthesia induction,and 30 minutes after extubation were recor-ded.The total dose of propofol,remifentanil and dexmedetomidine and the using rate of metaraminol were recorded.The visual analog scale scores 30 minutes after extubation,24 and 72 hours after surgery,the u-sing rate of tramadol,and the extubation time were recorded.Results Compared with the control group,the STAI-S scores of one day before surgery,and the incidence of postoperative delirium,the rate of using metaraminol,the VAS scores 30 minutes after extubation and 24 hours after surgery,the rate using of tram-adol were significantly decreased in the midazolam group(P＜0.05).There were no significant differences in total dose of propofol,remifentanil,and dexmedetomidine,extubation time between the two groups.Conclusion Preoperative oral midazolam can effectively reduce the incidence of postoperative delirium in elderly patients with preoperative moderate-severe anxiety undergoing radical resection of colorectal cancer.
RESUMO
BACKGROUND:Postoperative delirium is one of the serious complications after total knee arthroplasty,usually occurring 1-5 days after surgery,with confusion and cognitive impairment as the main manifestations,which is not conducive to the recovery of joint function in elderly patients.At present,the risk factors affecting delirium after total knee arthroplasty in the elderly are not clear,and there is a lack of clinical prediction studies to directly present them for promotion and application. OBJECTIVE:To explore the risk factors of delirium after total knee arthroplasty in elderly patients and establish a prediction model of nomogram. METHODS:Medical record data of 116 elderly patients receiving total knee arthroplasty treated in Ganzhou Hospital of Traditional Chinese Medicine,Jiangxi University of Chinese Medicine from January 2019 to December 2021 were retrospectively analyzed,of which 29 elderly patients with delirium after total knee arthroplasty were selected as the observation group,and the remaining 87 elderly patients without delirium after total knee arthroplasty were selected as the control group.Preoperative general clinical data,laboratory examination results,and surgical data were compared between the two groups.Multivariate Logistic regression analysis was used to analyze risk factors for delirium after total knee arthroplasty in elderly patients.The receiver operating characteristic curve was used to analyze the independent risk factors and obtain the best cut-off value.The nomogram model was constructed by R software. RESULTS AND CONCLUSION:(1)There were significant differences in age,cerebrovascular accident history,preoperative hospital stay,preoperative albumin,hemoglobin,American Society of Anesthesiologists classification,operation time,anesthesia time,and intraoperative blood transfusion volume between the two groups(P<0.05).(2)Multivariate Logistic regression analysis showed that old age,long hospital stay before surgery,high American Society of Anesthesiologists classification grade,and long operation time were risk factors for postoperative delirium in elderly knee arthroplasty patients,while high albumin and high hemoglobin were protective factors for postoperative delirium in elderly knee arthroplasty patients.(3)The areas under the curve of age,preoperative hospital stay,albumin,hemoglobin,American Society of Anesthesiologists classification grade,and operation time were 0.784,0.706,0.853,0.762,0.617,and 0.542,respectively.The optimal cut-off values were 75 years,7 days,40 g/L,125 g/L,3 and 200 minutes,respectively.(4)After internal data for verification,the consistency index was 0.974.The actual curve of the model was in good agreement with the ideal curve.(5)These results indicate that this nomogram model based on old age,long hospital stay,high American Society of Anesthesiologists classification grade,low albumin,low hemoglobin,and long operation time has far-reaching clinical significance for early identification,early warning and diagnosis of delirium risk in elderly patients after total knee arthroplasty.
RESUMO
Objective To investigate the effect of a three-tier delirium care management process in patients with acute stroke in neurology intensive care unit(NICU).Methods A total of 50 patients with acute stroke admitted to the NICU of the Fourth Hospital of Changsha from May to September 2021 were assigned to the control group.The patients in the control group received routine NICU nursing care to prevent delirium.Another 50 patients with acute stroke admitted to the NICU from December 2021 to April 2022 were assigned to the trial group.They were managed with the three-tier delirium nursing management process on top of the routine NICU nursing care for the control group.The incidence of ICU delirium(DICU),duration of DICU,length of stay in NICU and the incidence of delirium-related adverse events were compared between the two groups.The degree of delirium and cognitive function before and after the intervention were compared between the two groups as well.Results The trial group had significantly shorter duration of DICU and NICU stay(both P<0.05)and lower incidence rate of delirium-related adverse events(P<0.05)compared to the control group.After the intervention,the trial group showed significantly lower scores on the intensive care delirium screening checklist(ICDSC)and significantly higher scores of cognitive function compared to those of the control group(both P<0.05).Conclusion The three-tier delirium nursing management process can lower the occurrence of delirium in NICU patients with acute stroke,shorten the NICU stay,reduce the safety risk in nursing,and improve the cognitive function.
RESUMO
Objective To investigate the influencing factors of delirium after cardiac valve replacement went under car-diopulmonary bypass(CPB)with propofol sedation.Methods A total of 152 patients underwent cardiac valve replacement under CPB in Nanyang Central Hospital from January 2020 to December 2022 were selected as research objects,and they were randomly divided into observation group A[50 ≤bispectral index(BIS)＜60]and observation group B(35≤BIS＜45)according to the depth of propofol sedation,with 76 cases in each group.The clinical data such as age,gender,body mass index(BMI),diabetes,hypertension,coronary heart disease,chronic obstructive pulmonary disease,sleep disorder,nutritional disorder,anxiety,depression,smoking history,drinking history,preoperative cardiac insufficiency,intraoperative hypoxemia,intraoperative hypoproteinemia,postoperative acute renal injury,secondary intubation,massive blood transfusion,excessive pain,postoperative left ventricular ejection fraction(LVEF),surgical method and CPB time were collected,and the incidence of postoperative delirium of patients was evaluated by the confusion assessment method of intensive care unit(CAM-ICU)method.The incidence of postoperative delirium of patients between observation group A and observation group B was compared.The influencing factors of postoperative delirium occurrence was analyzed by using univariate and multivariate logis-tic regression analysis.Results Among the 152 patients underwent heart valve replacement,36 patients experienced postoperative delirium,with an incidence of 23.68％.The incidence of postoperative delirium of patients in the observation group A and the observation group B was 38.16％(29/76),9.21％(7/76),respectively;the incidence of postoperative delirium of patients in the observation group A was significantly higher than that in the observation group B(x2=17.617,P＜0.05).The gender,BMI,diabetes,hypertension,coronary heart disease,cognitive disorder,sleep disorder,nutritional disorder,anxiety,depression,smoking history,drinking history,intraoperative hypoxemia,intraoperative hypoproteinemia,postoperative acute renal injury,secondary intubation,massive blood transfusion,and surgical method were not related to postoperative delirium(P＞0.05);the age,chronic obstructive pulmonary disease,preoperative heart failure,excessive pain,postoperative LVEF,and CPB time were associated with postoperative delirium(P＜0.05).Multivariate logistic regression analysis showed that age 60 years,preoperative cardiac dysfunction,excessive pain,and CPB time≥100 minutes were risk factors for postoperative delirium(P＜0.05),while postoperative LVEF≤50％and propofol sedation depth of 35≤BIS＜45 were protective factors for postoperative delirium(P＜0.05).Conclusion Propofol sedation depth of 35≤BIS＜45,postoperative LVEF ≥50％can effectively reduce the risk of postoperative delirium after cardiac valve replacement under CPB.Age≥60 years old,preoperative cardiac insufficiency,excessive pain,and CPB time≥100 min can increase the risk of postoperative delirium.
RESUMO
Objective:To evaluate the effect of ultrasound-guided adductor canal combined with knee joint posterior capsule space block on the recovery period delirium in elderly patients undergoing total knee arthroplasty (TKA).Methods:A total of 68 elderly patients who underwent unilateral TKA at the Nanjing First Hospital from December 2021 to December 2022 were selected. They were randomly divided into a control group ( n=34) and an observation group ( n=34) using a random number table method. Both groups received general anesthesia, and the observation group received ultrasound-guided myofascial tube combined with knee joint posterior capsule space block before the surgery began. The incidence of delirium within 24 hours after surgery was mainly observed in two groups of patients. The surgical time, recovery time, intraoperative blood loss, infusion volume, total use of propofol and remifentanil were recorded; The resting and motor Visual Analogue Scale (VAS) scores of the patient were recorded at 4, 8, and 24 hours postoperatively. The patient′s serum tumor necrosis factor-α (TNF-α) and melatonin levels were measured on the day before surgery, the evening after surgery, and the first day after surgery. The subjective sleep quality score was recorded on the first day after surgery; The total dosage of sufentanil for patient-controlled intravenous analgesia (PCIA) within 24 hours after surgery, the effective number of compressions (P1) and actual number of compressions (P2) of PCIA, and the number of cases of additional oxycodone analgesia were recorded; The occurrence of respiratory depression, excessive sedation, nausea, and vomiting within 24 hours after surgery was recorded; The occurrence of complications of nerve block in the observation group was recorded. Results:The incidence of delirium during the recovery period in the observation group was lower than that in the control group ( P<0.05). The dosage of propofol and remifentanil in the observation group was lower than that in the control group (all P<0.05), and the awakening time was shorter than that in the control group ( P<0.05). The VAS scores at rest and exercise at 4, 8, and 24 hours after surgery in the observation group were lower than those in the control group (all P<0.05). Compared with the day before surgery, the observation group showed an increase in melatonin levels on the night after surgery ( P<0.05) and an increase in TNF-α levels on the first day after surgery ( P<0.05); The control group had a decrease in melatonin levels on the first day after surgery ( P<0.05), and an increase in TNF-α levels on the night and day after surgery (all P<0.05). The serum melatonin levels in the observation group were higher than those in the control group on the evening and first day after surgery (all P<0.05), and TNF-α levels were lower than those in the control group (all P<0.05). The subjective sleep quality score of the observation group showed that the total dosage of PCIA sufentanil, P1, P2, and the number of cases of additional oxycodone analgesia within 24 hours after surgery were lower than those of the control group (all P<0.05). The incidence of nausea in the control group (13 cases, 38.2%) was higher than that in the observation group (3 cases, 8.8%) ( P<0.05). Conclusions:In elderly patients undergoing unilateral TKA under general anesthesia, preoperative use of ultrasound-guided adductor tube combined with knee joint posterior capsule space block can effectively reduce the occurrence of postoperative delirium.

Objective: to describe a microtheory for nursing care in the prevention of delirium in older adult in the intensive care unit. Method: prescriptive theoretical research, based on substruction. Roy's Adaptation Model constructs were deduced and data from the phenomenon of nursing care in the prevention of delirium in older adult in intensive care were induced, based on an integrative literature review. Results: the microtheory has a theoretical and operational system and a model of care. In the theoretical system, Roy's focal and contextual stimulus constructs were used. From them, the concepts of focal and contextual care and the variable adaptive response to prevention were elaborated. From the relational statements, four axioms, two postulates, eight propositions and an epistemic assumption were elaborated. Two empirical indicators were established in the operating system: the Confusion Assessment Method for Intensive Care Units and the demographic/clinical history of the older adult. Subsequently, two transformational statements, four hypotheses and the model of care represented in figure were produced. Conclusion: the microtheory produced prescribes care in the prevention of delirium in older adult in intensive care, through a construct of interest to nursing, and allows interceptions for the development of instruments that guide nursing activities.
