Brief Summary

The objective of this study is to evaluate the effect of melatonin on post operative sleeping quality, anxiety, and post-operative opioid requirements in adults post coronary artery bypass graft (CABG) surgery.

Detailed Description

Sleep disturbance is common among patients undergoing coronary artery bypass graft (CABG), especially during the first week of the postoperative period. Sleep disorders result in important impacts on morbidity, mortality, and quality of life.

Many factors are thought to be the cause of sleep disturbance in patients who have undergone CABG. These factors include environmental stimuli (e.g. noise and uncomfortable beds), individual characteristics (e.g. primary sleep disorder and comorbid health), nature of cardiac illnesses, and surgical complications (e.g. incisional pain, use of diuretics and resultant nocturia, dyspnea, and difficulty in finding the proper position to sleep).

Furthermore, decreased plasma melatonin concentrations have been documented during surgery and the postsurgical period in patients having undergone CABG.

Melatonin is a neurohormone originating from the amino acid, tryptophan, and is mainly secreted by the pineal gland into the blood stream and the cerebrospinal fluid. It possesses a circadian secretion pattern with a low blood concentration during the day and a high concentration at night.

Arm && Interventions

Group	Intervention	Description
Control group	Placebo	Patients in the control group will receive placebo.
Melatonin group	Melatonin 5 MG	Three days before the operation patients will receive 5 mg of melatonin (Melatonin, Nature Made, Canada, and USA) one hour before assigned sleep time until the time of discharge from hospital.

Primary Outcome Measures

Name	Time	Method
Quality of sleep	Five days postoperative	Sleep quality will be evaluated using the Groningen Sleep Quality Score (GSQS), The GSQS consists of 15 questions about the previous night's sleep, answered with Yes or No.

Secondary Outcome Measures

Name	Time	Method
Anxiety	24 hours postoperative	The Hamilton Anxiety Rating Scale (HAM-A) is a psychological questionnaire employed by clinicians to rate the severity of anxiety. This scale includes 14 items. Each consists of a number of symptoms, and the symptoms are graded on a scale of zero to four.; Each item is scored on a scale of 0 (not present) to 4 (severe), with a total score range of 0-56, where \<17 indicates mild severity, 18-24 mild to moderate severity and 25-30 moderate to severe.
The degree of pain	24 hours postoperative	The degree of pain will be assessed using numerical rating scale (NRS) requires for sternal pain, the patient to rate their pain on a defined scale from 0-10 where 0 is no pain and 10 is the worst pain) measured at time intervals: 30 minutes, 6hours, 12hours, and 24h after extubation. If NRS \> 4 rescue analgesia will be given in form of IV morphine0.05mg /kg.
Opioid requirements	24 hours postoperative	Postoperative analgesia in the ICU was carried out for both groups. All patients received IV fentanyl infusion (0.5ugm/kg/hr) with 15ug bouls if sudden rise in Heart rate or mean arterial blood pressure \> 20% of base line to be stopped before extubation, after extubation Paracetamol 1gm was given every 8 hours for all patients, diclofenac 75mg /12hr.
