Filter by:Postoperative delirium (POD) is common in elderly patients recovering from surgery and anesthesia. POD has adverse effects on early and long-term prognosis. The incidence of POD increases with age and patients with preoperative cognitive changes or coexisting diseases. The bispectral index (BIS) is an electroencephalographic measurement commonly used to monitor the depth of anesthesia. Low intraoperative BIS value (BIS<40) and prolonged duration of low BIS value maybe risk factors of POD. A small sub-study of BALANCED Anaesthesia Study demonstrated a protective effect of targeting a BIS of 50 to reduce POD compared with a BIS of 35. The stability of BIS during general anesthesia may affect the risk of POD in elderly patients. Therefore, it is very important to maintain a stable BIS value as much as possible during general anesthesia surgery, and a general anesthetic with good BIS stability is even more needed in clinical practice. Cyclopofol is a new type of anesthetic/sedative that reportedly provides good efficacy and safety. Cyclopofol has a more stable effect on BIS, so whether the use of cyclopofol in elderly patients undergoing orthopedic surgery can reduce the occurrence of POD, improve prognosis, and exert a brain protective effect will be of great importance and clinical research value.
There have been limited studies on delirium in patients hospitalized with acute stroke. There have been no studies on the potential impact of overnight neuro-checks and resulting sleep disruption on delirium or other outcomes. Additional research is needed to determine if overnight checks are necessary or even harmful. We aim to find out if stopping overnight neuro checks may prevent delirium and benefit the patient.
This research investigates the effectiveness of a care package used in the care of patients undergoing coronary artery bypass graft (CABG) surgery in preventing postoperative delirium. CABG surgery is a common procedure used to increase blood flow to the heart and is typically applied in patients with severe cardiac diseases. However, this procedure can increase the risk of postoperative delirium, especially among elderly and critically ill patients. In this study, the goal is to reduce this risk by implementing a care package. The care package includes optimal pain management, sleep regulation, mobilization, ensuring patient orientation, and appropriate medication management. The results of the research will be used to determine whether the use of this care package is effective in reducing the risk of delirium after CABG surgery. This could potentially improve patient outcomes and allow for more efficient use of hospital resources.
Background: Delirium not only has a high incidence rate among hospitalized patients but also increases mortality rates, causes distress to patients and their families, and adds to healthcare costs. Studies have shown that non-pharmacological preventive measures can effectively prevent delirium. However, critically ill patients with multiple tubes and devices cannot receive home care due to their unstable condition. Therefore, this study aims to design multiple measures resembling a home environment in the hospital ICU to reduce the incidence of delirium. Objectives: Primary outcomes:the incidence and duration of delirium.Secondary outcomes :hospital stay, mortality rates, and patient or family satisfaction. Methods and Procedures: A prospective randomized double-blind study design. The study is planned to be conduct from January 1,2024 to December 30,2024。 Prior to enrollment, informed consent forms will be obtained and patients from six ICUs in the hospital. Inclusion criteria: Adult patients aged 18 or above. No maximum age limit. Patients with a Richmond Agitation-Sedation Scale score ranging from -3 to +4.Exclusion criteria: Patients with an existing diagnosis of delirium. Patients who were unable to communicate(GCS≦3）。 Patients with moderate to severe dementia.Patients with severe sedation or coma(GCS≦3）。 Sample Size: The control group's delirium incidence rate of 69.1% based on a study. The experimental group is expected to reduce delirium incidence rate to 40%。 A α value of 0.05, power 80%, each group will require 45 participants, total sample size 90 participants.A loss to follow-up rate about 15%。 To improve the effectiveness of the research design results, sample size is increased to 104 and each group is 52 participants. Intervention Design:Each delirium assessment using the ICDSC, both groups will undergo routine assessment using RASS. Control Group: Receive traditional comprehensive care in the ICU based on the PADIS assessment. This care will be administered by ICU nurses and will include pharmacological treatments as well as nursing interventions. Experimental Group: ICDSC along with PRE-DELIRIC model. Intervention: In addition to the routine comprehensive care provided in the ICU, the experimental group will receive SMART HOME care interventions. Outcome measures :ICDSC,PRE-DELIRIC,Incidence of Delirium,Duration of Delirium,LOS,Mortality Rate,Satisfaction.
The purpose of this research is to investigate whether addition of the EyeControl-Pro platform as an adjunct to standard guideline-based intensive care unit management of critically ill patients is effective in reducing delirium incidence and severity.
This is a prospective, multi-center, randomized effectiveness trial of the CardioGard Embolic Protection Cannula in high-risk valve surgery patients.
The goal of this multi-site observational study is to compare delirium rates, days on mechanical ventilation, and Post Intensive Care Syndrome (PICS) rates in adult Intensive Care Unit (ICU) patients. The study will examine patients whose sedation and analgesia infusion titration is managed with both Richmond Agitation and Sedation Scale (RASS) and Processed Electroencephalography (pEEG) monitoring vs patients who receive RASS monitoring alone. The main questions are: - Compared to RASS monitoring method alone, does the use of 4 channel pEEG monitor in conjunction with RASS to guide the management of sedation and analgesic in patients who are ventilated reduce the average number of delirium days, measured by Intensive Care Delirium Screening Checklist (ICDSC)? - To determine when compared to RASS monitoring alone if the use of 4 channel pEEG monitor in conjunction with RASS to guide the management of Intravenous (IV) sedation and analgesia in ventilated patients reduces the days a patient spends on a mechanical ventilator when compared to RASS only monitoring from retrospective data. - To determine when compared to RASS monitoring method alone, does the use of 4 channel pEEG monitor in conjunction with RASS experience lower doses of sedation and analgesia infusions? - To determine when compared to RASS monitoring method alone, does the use of 4 channel pEEG monitor in conjunction with RASS experience less incidence and duration of PICS?
The incidence of postoperative delirium in patients after cardiovascular surgery is very high, which seriously affects the short-term and long-term prognosis of patients, but its mechanism is not clear. Recent studies have found that lactic acid participates in the process of sepsis by inducing histone lactatation in macrophages. histone H3 lysine 18 lactylation (H3K18la) is significantly associated with the severity of disease and inflammatory response. Inflammation plays an important role in postoperative delirium. We therefore hypothesized that macrophage H3K18la also plays a role in postoperative delirium. At the same time, the latest literature shows that the early markers of Alzheimer's disease (AD), such as Aβ, exosomes and phosphorylated tau, etc. [5], can also be detected in the serum of AD patients. Given the obvious correlation between Alzheimer's disease and postoperative delirium [6], we hypothesized that serum biomarkers of AD could also be used as serum biomarkers for postoperative delirium. The objectives of this study were to investigate the correlation between H3K18 in serum monocytes and postoperative delirium and its severity in patients undergoing cardiovascular surgery. Meanwhile, we also detect the serum levels of biomarkers of AD, such as Aβ, tau and exosomes etc., in patients undergoing major cardiac surgery. We aim to find the serum biomarkers of delirium after major cardiac surgery, so as to provide a more convenient diagnostic basis for the prevention of postoperative delirium.
This study is to investigate the predictors of post-stroke delirium, develop and validate a nomogram of post-stroke delirium in the ischemic stroke patients.
Delirium is an acute confusional state that is experienced by many older adults who are admitted to hospital. To treat delirium the underlying cause needs to be identified promptly, but this is challenging. One of the potential causes of delirium is infection. Urine tests show that most patients experiencing delirium have bacteria in their urine, however, bacteria in the urine is common among older adults, and does not automatically indicate an infection is present. As a result it is difficult to know whether a lower urinary tract infection is present as individuals with delirium are frequently unable to report clinical signs of infection - symptoms of pain or discomfort with urination, having to urinate more frequently or pelvic discomfort. Very often, individuals with delirium are treated with antibiotics despite the fact that it is unknown whether antibiotics help to improve delirium in cases where bacteria in the urine is present. This proposed study is a randomized controlled trial that will examine if adults (age 60 or older) with delirium and suspected infection benefit from taking antibiotics.
