Comparison of Postoperative Delirium in Elders Anaesthetised With Midazolam and Without Midazolam

Postoperative Delirium Clinical Trial

Official title:
Comparison of Postoperative Delirium in Elders Anaesthetised With Midazolam and Without Midazolam During Non-cardiac Surgery

Clinical Trial Summary

This research project is an observational cohort study by prospective chart review of patients that underwent surgery in multi-centers, China, in the years 2020-2022. The purpose of this study is to compare the occurrence of postoperative delirium With Midazolam and Without Midazolam During Non-cardiac Surgery in Elders.

Clinical Trial Description

Post operative delirium will be diagnosed using the 3D- CAM(Confusion Assessment Method) which tests for four features with a series of questions. The features include 1) acute onset and fluctuating course,2) inattention,3) disorganized thinking and 4) altered level of consciousness. Diagnosis of delirium is made if features 1 and 2 and either 3 or 4 are present. The demographic data of the patients,type and site of surgery will be noted. Preoperative hemoglobin, serum electrolytes and blood urea will be recorded. The intraoperative factors like duration of surgery and anaesthesia,use of intravenous fluids ,blood loss, number blood units transfused and opioid use will be studied at the time of surgery. The time to emergence and extubation following the completion of surgery will be noted. The postoperative factors like postoperative pain, nausea and vomiting, fever,hemoglobin,serum electrolytes and blood urea will be noted. Preoperative and postoperative pain will be assessed using the numerical rating score on a scale of one to ten. The association of various preoperative,intraoperative and postoperative factors with POD will be determined. ;
