NCT04483596

Brief Summary

POD has been reported to be associated with a large number of risk factors: age as POD occurs in 10% to 61% of those aged 65 or older, dementia, impaired left ventricular function, electrolyte disorder, alcoholism, smoking, high perioperative transfusion requirements, intraoperative pressure fluctuation, and use of benzodiazepine POD occurs mostly in some types of surgery, such as orthopedic surgeries, major gastrointestinal surgery, and major cardiovascular surgeries, surgery under general anesthesia, prolonged surgery, emergency surgery Previous studies done before to prove the efficacy of melatonin to decrease the incidence of postoperative delirium in patients with multiple risk factors for POD as traumatic geriatric patients were concerned only with the type of surgery as hip replacement or with spinal anesthesia but no study was done before to assess the prophylactic effect of melatonin to decrease the incidence of postoperative delirium in geriatric patients under general anesthesia ,which represents an independent risk factor for POD. So,this double blinded RCT will try to fill this gap in literature.

Outcome Measures

Primary Outcomes (1)

  • postoperative delirium

    Detection of the difference in incidence of POD between melatonin group and control group using the Abbreviated Mental Test (AMT)

    3 postoperative days

Study Arms (2)

M

will receive 5 mg melatonin orally at 9 p.m. the night before surgery and another 5 mg melatonin with 15 ml of plain water 30 min before operation and 5 mg melatonin at 9 p.m. in the day of operation and for the first three postoperative days

Drug: melatonin effect on the Abbreviated Mental Test

C

received a placebo in the form of one tablet of 500 mg paracetamol that packaged the same way as melatonin at the same times

Drug: melatonin effect on the Abbreviated Mental Test

Interventions

Questionnare 1. Age 2. Time (to nearest hour) 3. Address for recall at end of test (Ask patient to repeat the address to ensure it has been heard correctly) 4. Year 5. Name of hospital 6. Recognition of two persons (e.g. doctor, nurse) 7. Date of birth 8. Year of any famous event e.g: the last Egyptian revolution 9. Name of the present monarch 10. Count backwards from 20 to 1
