About this study

Official title: The Role of Endogenous Melatonin Levels on Preoperative and Postoperative Anxiety in Living Liver Donors

Interesting in living liver donor transplantation have greatly increased because of inadequacy of cadaveric organs and the inability to supply the growing need for cadaveric transplantation. Surgical procedures applied to living liver donors do not only physically demand organs, but can also cause psychological burden. It has been reported that melatonin had antioxidant, antinociceptive, hypnotic, anticonvulsant, neuroprotective, anxiolytic, sedative and analgesic properties. It was shown to administration of exogenous melatonin has been increase sedation and decrease anxiety in the preoperative period compared to placebo.

The aim of this study; To investigate preoperative and postoperative anxiety levels of CKV and to exam the relationship between anxiety levels and endogenous melatonin levels.

Read the detailed description

Interesting in living liver donor (LLD) transplantation have greatly increased because of inadequacy of cadaveric organs and the inability to supply the growing need for cadaveric transplantation. Surgical procedures applied to LLD do not only physically demand organs, but can also cause psychological burden. Preoperative anxiety is seen in 60-80% of patients scheduled for surgery. It has been reported that melatonin had antioxidant, antinociceptive, hypnotic, anticonvulsant, neuroprotective, anxiolytic, sedative and analgesic properties. It was shown to administration of exogenous melatonin has been increase sedation and decrease anxiety in the preoperative period compared to placebo.

The aim of this study; To investigate preoperative and postoperative anxiety levels of LLD and to exam the relationship between anxiety levels and endogenous melatonin levels.

This prospective clinical study will perform at Inonu University Liver Transplant Institute. Anxiety of the patients included in the study will be measure with Spielberger State Anxiety Scale Scale (STAI FORM TX-1) in preoperative and postoperative period. It was designed to assess levels of state anxiety and traint anxiety, through 40 items scored by a likert-scale. Range of scores for each subtest is 20-80, the higher score indicating greater anxiety. A cut point of 39-40 has been suggested to detect clinically significant symptoms for the S-Anxiety scale. Patients without premedication will admit to the operating room. Before induction of anesthesia, the vascular access will perform and 3 mL of blood sample will take to check for preoperative melatonin level. Standard general anesthesia will perform to all donors. At the end of surgery, the patients will take to intensive care unit. After 24 hours, blood samples will take for post-melatonin. Plasma melatonin concentrations will measure using High Performance Liquid Chromatography (HPLC) method in Inonu University Faculty of Pharmacy Analytical Chemistry Department research laboratory.

What is being measured

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

  1. The correlation between anxiety and melatonin levels

    Melatonin is a hormone secreted from the pineal gland. It shows a daily biorhythm. The circadian rhythm of melatonin changes according to age and it's production decreases with older ages. Melatonin level can be measured in the blood and in urine collected for 24 hours.It was designed to assess levels of state anxiety and traint anxiety, through 40 items scored by a likert-scale. the higher score indicating greater anxiety. A cut point of 39-40 has been suggested to detect clinically significant symptoms for the S-Anxiety scale.

    Measured: up to 24 hours

The record says: status not confirmed, as of the sponsor's last update on 18 Jan 2020. 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 Turkey (Türkiye). 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.

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?

The correlation between anxiety and melatonin levels (time frame: up to 24 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04230707, which also lists 1 linked publication.

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 18 Jan 2020; AzTrials last refreshed its copy on 8 Nov 2026.
