About this study

Official title: Effects of Intravenous Lidocaine on Serum BDNF, NGF, miRNA-206 and miRNA-98 in Elderly Patients Undergoing Abdominal Surgery Under General Anesthesia

The purpose of this study is to investigate the efficacy of intravenous lidocaine on BDNF, NGF, miRNA-206 and miRNA-98 in serum in elderly patients undergoing abdominal surgery under general anesthesia.

Read the detailed description

Postoperative cognitive dysfunction (POCD) is a major complication following surgeries and anesthesia, especially in elderly individuals. Lidocaine, an inexpensive, widely available, and relatively safe compound, is a local anesthetic that readily crosses the blood-brain barrier. Intravenous lidocaine can reduce the incidence of POCD. However, the mechanism is still unclear.

Brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF), which are regulated by miRNA-206 and miRNA-98 respectively, play a key role in learning, memory, and cognition. Previous studies have shown that the levels of BDNF and NGF can be improved by lidocaine.

The objective of this study is to investigate the efficacy of intravenous lidocaine on the incidence of early POCD, and the levels of BDNF, NGF, miRNA-206 and miRNA-98 in elderly patients undergoing abdominal surgery under general anesthesia.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • LidocaineDrug

    Intravenous bolus of 1.5 mg/kg of lidocaine followed by a continuous infusion of 3.0 mg/kg for the frst hour, 1.5 mg/kg for the second hour, 0.7 mg/kg until the end of the surgery

  • Normal saline (NS)Other

    Patients are received equal volumes of saline intravenously until the end of the surgery

What is being measured

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

  1. Changes from Baseline BDNF at 1, 3 days after surgery

    Venous blood samples were sampled before anaesthesia induction and 1, 3 days after surgery for the BDNF by using Enzyme-linked immunosorbent assay.

    Measured: at preoperation,1 and 3 days postoperation

  2. Changes from Baseline NGF at 1, 3 days after surgery

    Venous blood samples were sampled before anaesthesia induction and 1, 3 days after surgery for the NGF by using Enzyme-linked immunosorbent assay.

    Measured: at preoperation,1 and 3 days postoperation

  3. Changes from Baseline miRNA-206 at 1, 3 days after surgery

    Venous blood samples were sampled before anaesthesia induction and 1, 3 days after surgery for the miRNA-206 by using PCR.

    Measured: at preoperation,1 and 3 days postoperation

  4. Changes from Baseline miRNA-98 at 1, 3 days after surgery

    Venous blood samples were sampled before anaesthesia induction and 1, 3 days after surgery for the miRNA-98 by using PCR.

    Measured: at preoperation,1 and 3 days postoperation

Secondary outcomes (1)
  1. Changes from Baseline mini-mental state examination (MMSE) at 1, 3 days after surgery

    MMSE was performed

    Measured: at preoperation,1 and 3 days postoperation

Questions about this trial

What is this clinical trial studying?

A study testing Lidocaine and Normal saline (NS) in people with Organ Protection, run by General Hospital of Ningxia Medical University.

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 3 inclusion and 8 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: status not confirmed, as of the sponsor's last update on 16 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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?

Results are not available in the source record.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes from Baseline BDNF at 1, 3 days after surgery (time frame: at preoperation,1 and 3 days postoperation). The study lists 4 primary outcomes in all. 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 16 Aug 2022.
