About this study

Official title: Relationship Between Melatonin Level and Postoperative Analgesia Consumption in Bariatric Surgery Patients.

Bariatric surgical procedures are associated with low short-term mortality and may be associated with long-term reductions in all-cause, cardiovascular, and cancer-related mortality. This surgeries are major surgeries include risk of mortality still.

Melatonin is a hormone secreted from the pineal gland. Melatonin is an antioxidant, antinociceptive, hypnotic, anticonvulsant, neuroprotective, anxiolytic, sedative and analgesic. Melatonin is neurohormone with the profile of a novel hypnotic-anesthetic agent.

The purpose of this study is to investigate the preoperative, perioperative and postoperative melatonin levels in bariatric surgery under general anesthesia and to investigate the relationship between melatonin level and analgesia requirement.

Bariatric surgical procedures are associated with low short-term mortality and may be associated with long-term reductions in all-cause, cardiovascular, and cancer-related mortality. This surgeries are major surgeries include risk of mortality still.

Melatonin is a hormone secreted from the pineal gland. Melatonin is an antioxidant, antinociceptive, hypnotic, anticonvulsant, neuroprotective, anxiolytic, sedative and analgesic. Irregularity of melatonin secretion causes a sleep irregularities, psychosis in intensive care unit and some behavioral disorder. The hypnotic, antinociceptive, and anticonvulsant properties of melatonin endow this neurohormone with the profile of a novel hypnotic-anesthetic agent.

The purpose of this study is to investigate the preoperative, perioperative and postoperative melatonin levels in bariatric surgery under general anesthesia and to investigate the relationship between melatonin level and analgesia requirement.

What is being measured

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

  1. Melatonin Level

    Melatonin is a hormone secreted from the pineal gland. It shows a daily biorhythm. Melatonin level can be measured in the blood and in urine collected for 24 hours.

    Measured: Change from Baseline melatonin at postoperative 24 hours

Secondary outcomes (1)
  1. Morphine consumption

    Morphine is analgesic agent. It will used postoperative period

    Measured: change from postoperative up to 24 hours
