Effects of Sleep Quality on Melatonin Levels and Inflammatory Response After Major Abdominal Surgery

June 5, 2017 updated by: Necdet Fatih Yasar, Eskisehir Osmangazi University

Effects of Sleep Quality on Melatonin Levels and Inflammatory Response After Major Abdominal Surgery in an Intensive Care Unit

Endogenous melatonin is produced by the pineal gland at night under normal conditions and regulates the sleep-wake cycle. Artificial light administered at night suppresses melatonin production and sleep disturbances are accompanied by abnormal melatonin secretion such as phase delay. Therefore, dramatic disturbances of endogenous rhythms in intensive care unit patients have remarkable effects on melatonin production. In addition to its physiological roles in regulating sleep patterns, melatonin has been demonstrated to provide antiinflammatory effects in experimental models. Although some previous studies have investigated the circadian pattern of melatonin in intensive care unit patients, the investigators think that the present study is the first one that will assess the effects of controlling noise and light on melatonin and inflammatory response after major abdominal surgery.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is going to be conducted in accordance with the Helsinki Declaration and has been approved by Eskisehir Osmangazi University Ethics Committee. Forty consecutive patients, aged 18-65, who will undergo elective major abdominal operations will be enrolled in the study after obtaining informed consent. All patients will receive adequate postoperative pain management with the Pain Buster ® system and patient-controlled intravenous analgesia (PCA). The patients will be randomly assigned to either the experimental group or the control group. The control group will receive the usual care. The patients in the experimental group will be screened in the side-rooms where normally the patients who either have infections or are at risk of infection, are nursed. The study intervention will include dimming the lights to 40 lux and closing the doors of the side-room to decrease the noise level below 40 decibels (dB) between 11:00 p.m.-5:00 a.m.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

ACTIVE_COMPARATOR: Usual Care
After a major abdominal surgery, the control group will receive the usual postoperative care including continous infusion of Bupivacaine (Bustesin®) via Pain Buster ® system into the wound at a rate of 5cc/hour and infusion of Tramadol HCl (Tramosel®) via PCA (Gemstar®) in the surgical intensive care unit.
