Official title: Methylprednisolone Combined Electric-acupuncture Treatment Effects on Cognitive Function After Surgery for Elderly Patients With General Anesthesia
Postoperative cognitive dysfunction (POCD) refers to the patients in the central nervous system complications after general anesthesia and clinical manifestations of mental disorder, anxiety, personality changes, impaired memory, personality, social skills and cognitive function after surgery for this decline is called postoperative cognitive dysfunction.Due to the lack of effective clinical treatments, how to prevent and solve the postoperative cognitive dysfunction has become a difficulty and a focus of research in the field of anesthesia.Methylprednisolone is a new type of cortical hormone, because of its strong anti-inflammatory effect, less adverse reactions, is widely used in clinical anesthesia.Electric acupuncture as a kind of traditional treatments, after years of clinical application and achieved good curative effect in practice.In this paper by comparing brain oxygen saturation, blood biochemical indexes, Montreal cognitive assessment scale (MOCA) on cognitive function in patients with grade indexes, such as observation of methylprednisolone combined electric acupuncture treatment of elderly patients with general anesthesia early after the operation, the influence of cognitive function.
Through comparing the operation of cerebral oxygen saturation, blood biochemical indexes, Montreal cognitive assessment scale (MOCA) on cognitive function in patients with grade indexes, such as observation of methylprednisolone combined electric acupuncture treatment of elderly patients with general anesthesia early after the operation, the influence of cognitive function.

Choose descending colon cancer radical general anesthesia, 80 cases of patients, ASA Ⅱ ~ level III, aged 65 ~ 75, were randomly divided into two groups: anesthesia method selects the tracheal intubation general anesthesia.All Diprifusor propofol used in patients with TCI system, with the initial plasma concentration of 2.0 ug/ml start TCI, and intravenous sufentanil injection 0.15 ug/kg, propofol 1 ug/ml every 1 minute.After the BIS value < 75, start the fentanyl TCI system, maintaining the plasma concentrations of 4 ng/ml, vein to the interaction between rocuronium 0.8 mg/kg, insert the endotracheal intubation after mechanical ventilation.Adjust the propofol infusion control electrical double-frequency index between 45 to 55.The experimental group to give intravenous methylprednisolone 1 mg/kg/sack.And 1 mg/kg * d continuous application to the third day after surgery.
1 day before the surgery, postoperative 1 day, 2 days, 3 days, 7 days the MOCA scale to assess cognitive function after surgery for the patient.(T0) prior to the induction and bi (T1), 24 h after surgery (T2) and 48 h after surgery (T3) extraction in patients with venous blood, adopts the method of enzyme-linked immunosorbent (ELISA) determination of serum IL - 1 beta, IL - 6, Aβ1-42, p- Tau concentration.In rSO2 intraoperative continuous monitoring, and calculate the average rSO2, intraoperative rSO2 down the biggest percentage compared with basic value rSO2 % of Max.And record the occurrence of adverse reactions to special circumstances.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Methylprednisolone and Physiological saline in people with Postoperative Complication and Cognitive Retention Disorder, run by Shengjing Hospital 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 4 inclusion and 6 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 20 Dec 2016. 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. 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.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Contact Yanchao Yang, master (18940252916, yyc25714104@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Cognitive function evaluation as measured by Montreal cognitive assessment scale score (time frame: Cognitive function evaluation 1 day after the surgey). 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 20 Dec 2016; AzTrials last refreshed its copy on 31 Oct 2026.
