About this study

Official title: Correlation Analysis of Postoperative Delirium and Postoperative Neurocognitive Disorder in Elderly Patients With Gastrointestinal Neoplasms

This is a prospective cohort study to explore the differences of serum indicators between elderly gastrointestinal neoplasms patients with postoperative delirium (POD) who either develop or do not develop long-term postoperative neurocognitive disorders (pNCD).

Read the detailed description

The purpose of this study is to explore the differences of serum indicators between elderly gastrointestinal neoplasms patients with postoperative delirium (POD) who either develop or do not develop long-term postoperative neurocognitive disorders (pNCD).

Elderly gastrointestinal neoplasms patients aged 65 and above, undergoing surgical operations at Xuanwu Hospital, Capital Medical University, were selected. The serum indicators of all patients were measured before surgery, and neurocognitive function of all patients was assessed using the Montreal Cognitive Assessment (MoCA) within 1 week before surgery. General patient data such as sex, age, comorbidities, BMI, ASA classification, and MoCA scores were collected. Under routine anesthetic management of the Department of Anesthesiology and Surgical Operations at Xuanwu Hospital, endotracheal intubation general anesthesia was performed. Intraoperative monitoring included heart rate, blood pressure, pulse oximetry, and body temperature, with surgery and anesthesia times, and fluid balance recorded. The serum indicators of all patients were measured after surgery. Within 7 days post-surgery, delirium assessment was conducted using the Confusion Assessment Method (CAM), classifying patients into POD and non-POD groups. For the patients in the POD group, neurocognitive function was assessed at a period of time after surgery to determine the presence of pNCD, further dividing the POD group into pNCD and non-pNCD subgroups. The correlation between POD and pNCD was explored by comparing the changes of serum indicators before and after surgery in the pNCD and non-pNCD subgroups.

Study groupRoleWhat they receive
postoperative delirium(POD) and postoperative neurocognitive disorder(pNCD)Delirium (CAM scale ) was assessed 7 days after surgery and divided into POD and non-POD groups; one of the above scenarios indicated postoperative delirium;The patients in the POD group were evaluated for cognitive function at 1 month and 12 months after surgery to determine whether pNCD occurred. The patients in the POD group were further divided into pNCD subgroup and non-PNCD subgroup, and the changes of serum indicators before and after surgery in the pNCD and non-pNCD subgroups were compared.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. the changes of blood biomarkers before and after surgery between elderly gastrointestinal neoplasms patients with postoperative delirium (POD) who either develop or do not develop postoperative neurocognitive disorders (pNCD) one month after surgery

    Perioperative changes in blood-based biomarkers can reflect the pathophysiological processes of diseases. Current studies indicate that the perioperative levels of blood-based biomarkers may be associated with postoperative neurocognitive disorders in elderly patients. These blood-based biomarkers may provide novel avenues for the early diagnosis, prevention, and improvement of outcomes in elderly patients with postoperative neurocognitive disorders.

    The procedures are as follows:

    Neurocognitive function assessments were conducted on the enrolled patients within one week before surgery, one month after surgery, and twelve months after surgery, respectively. Whether the patients developed postoperative delirium was evaluated within seven days after surgery. Venous blood was drawn before surgery and within three days after surgery to detect the levels of brain-derived neurotrophic factor (BDNF), high-sensitivity C-reactive protein (hs-CRP), and homocysteine (Hcy).

    Measured: 2024.5.9-2026.6.1

Questions about this trial

What is this clinical trial studying?

An observational study of Postoperative Delirium and Postoperative Neurocognitive Disorder, run by Xuanwu Hospital, Beijing at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 3 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Lei Zhao, Doctor's (+8613811035886, zhaoalei@sina.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

the changes of blood biomarkers before and after surgery between elderly gastrointestinal neoplasms patients with postoperative delirium (POD) who either develop or do not develop postoperative neurocognitive disorders (pNCD) one month after surgery (time frame: 2024.5.9-2026.6.1). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Apr 2025.
