Delirium in Old Age Clinical Trial

Official title: Combination of Haloperidol and Magnesium for Delirium Prevention in Critically Ill Elderly Patients After Elective Major Surgery

Status Completed

Clinical Trial Summary

Objective: The aim of this randomized double blinded study is to investigate the effectiveness and safety of the prophylactic use of haloperidol with or without magnesium (Mg) for delirium in high risk elderly patients postoperatively.

Patients and methods: 135 patients aged ≥ 65< 80 years old with PRE-DELIRIC Score 50% or more (20) were admitted to the ICU non-intubated following major non cardiac surgeries randomized into 3 groups, Group I received 1 mg haloperidol intravenously 3 times daily and magnesium sulfate 4 g intravenous infusion (IVI) in 1st day (diluted in 50 ml D5W over 24 hours) then 2g IVI over 24 hours (diluted in 50 ml D5W over 24 hours) for 3 days, Group II received 1 mg haloperidol intravenously 3 times ,Group III received 1 mL 0.9% of sodium chloride intravenously 3 times daily. The primary outcome of the study will be the incidence of delirium.

Clinical Trial Description

This prospective randomized double-blind placebo-controlled study will be conducted in Ain Shams university surgical ICU on 135 patients aged ≥ 65< 80 years old with PRE-DELIRIC Score 50% or more (20) who are admitted to the ICU non-intubated following major non cardiac surgeries and anticipated intensive care unit (ICU) stay of at least 2 days as estimated by the attending intensivist after the approval of the research ethical committee and obtaining patients' or patients ' relatives written informed consent.

The study medications are continued until ICU discharge or until delirium occurred. In the latter case, study medications are stopped, and patients could be treated with dexmedetomidine.

For delirium prevention non-pharmacological interventions are also implemented like early mobilization, improving patient circadian rhythm, noise reduction are parts of the daily ICU care.

Patients will receive fentanyl infusion for analgesia. Those patients achieving a RASS score of ± 1 or 0 are monitored daily for delirium using the Confusion Assessment Method for the ICU (CAM-ICU). Patients are diagnosed with delirium if they have at least 1 positive CAM-ICU without RASS -4/-5 during a complete day. Clinicians collecting data on delirium are all experienced in delirium assessment using the CAM-ICU. All patients are screened at least three times daily, and more often if required. ;
