EFFECT OF LOW DOSE INTRAVENOUS KETAMINE GIVEN BEFORE INDUCTION ON POSTOPERATIVE COGNITIVE FUNCTIONS IN PATIENTS WITH COVID-19
An observational study of COVID-19 Pandemic, run by Kocaeli Derince Education and Research Hospital.
Trial summary
Postoperative psychomotor dysfunction is called postoperative cognitive dysfunction, and the incidence of postoperative complications is high, especially in elderly patients undergoing major surgery. This complication; It can be attributed to the anesthetic agents used, their doses, and the duration of the surgery. Read more about this study

About this study
Official title: EFFECT OF LOW DOSE INTRAVENOUS KETAMINE ON POSTOPERATIVE COGNITIVE FUNCTIONS
Postoperative psychomotor dysfunction is called postoperative cognitive dysfunction, and the incidence of postoperative complications is high, especially in elderly patients undergoing major surgery. This complication; It can be attributed to the anesthetic agents used, their doses, and the duration of the surgery. Although SARS-CoV-2 virus causes an infection called Covid-19 that mainly affects the respiratory tract, data have been obtained that it can enter the nasal mucosa, reach the central nervous system via olfactory fibers or hematogenous way, and infect endothelial cells and neurons. The immune system is activated due to endothelial cell damage, vascular permeability increases, and the risk of thrombosis occurs. Cerebral hypoperfusion promotes Lewy body development, especially by increasing amyloid plaque formation and inducing serine phosphorylation. The formation of these plaques, which are responsible for the development of Alzheimer's and Dementia, suggests that Covid-19 may have long-term neurological complications. In our study, we included patients who were scheduled for cholecystectomy, who had and did not have covid-19 infection. Covid-19 infection (Group 1), no previous (Group 2), COVID-19 and pre-induction low-dose intravenous ketamine (0.5 mg/kg) administered (Group 3), non-covid-19 and pre-induction low-dose intravenous ketamine We aimed to evaluate and compare postoperative cognitive functions in patients (Group 4) administered (0.5 mg/kg). Ketamine is a sedative, hypnotic and analgesic agent and has an effective role in balanced anesthesia. In addition, its use reduces the need for the use of other anesthetic agents. The use of ketamine in normal doses causes a decrease in brain and cognitive functions; The use of sub-anesthetic doses before induction has positive effects on recovery and cognitive functions. Depth of anesthesia with bispectral index continuously before and throughout the operation; The lowest and highest values were recorded by regional cerebral oximetry (rSO2) measurement. Cognitive tests were performed 1 day before the operation, at the 12th hour and 30 days after the operation. MMT (mini mental test), Verbal Fluency Test (verbal fluency test), Clock Drawing Test (clock drawing test) Aldrete recovery scores were evaluated at the 2nd and 5th minutes after extubation. The study included 160 patients, 35-55 young and middle-aged, ASA I and II. Patients who underwent emergency surgery, had malignancy, and had a known chronic disease were excluded from the study.

Questions about this trial
What is this clinical trial studying?
An observational study of COVID-19 Pandemic, run by Kocaeli Derince Education and Research Hospital.
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: status not confirmed, as of the sponsor's last update on 12 Apr 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. 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?
evaluation of cognitive function (time frame: 6 months). 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 12 Apr 2022.
