Postoperative Cognitive Dysfunction in Heart Surgery

Completed

• Conditions: Postoperative Cognitive Dysfunction
• Interventions: Other: Postoperative cognitive functions of particiants undergoing open heart surgery; Other: Preoperative cognitive functions of participants undergoing open heart surgery

• Registration Number: NCT05406843
• Lead Sponsor: Kocaeli University

Brief Summary

To determine the rate of Postoperative Cognitive Dysfunction (POCD) in the early and late postoperative periods by comparing the preop and postop period mini mental status tests in participants undergoing open heart surgery, and to compare the results of the investgators clinic with the world literature.

Detailed Description

Postoperative delirium (POD) and Cognitive Dysfunction (POCD) are changes in mental status, especially in the geriatric surgery population.Unlike other forms of delirium, POD results in early full recovery.Postoperative Cognitive Dysfunction (POCD) is more difficult to define and implies temporal consciousness impairment associated with surgery.

While the diagnosis of delirium requires the detection of symptoms, the diagnosis of POCD requires preoperative neuropsychological testing and determining how much reduction will mean cognitive dysfunction. Postoperative delirium management is complex and requires multiple strategies. Methods of treating and preventing POCD are still uncertain.It is known that POCD is most commonly seen in patients undergoing open heart surgery.In this study, the investigators aim is to evaluate whether there is any change in cognitive status in the postoperative period compared to the preoperative period of participants who will undergo open heart surgery due to valve pathology or coronary stenosis.

Arm && Interventions

Group	Intervention	Description
Postoperative cognitive status of participants undergoing open heart surgery	Postoperative cognitive functions of particiants undergoing open heart surgery	Detection of postoperative cognitive impairment is difficult and it starts with testing in the preoperative period. In this study, it was aimed to determine the postoperative cognitive impairment by comparing it with the cognitive functions in the preoperative period using the Minimental status test in the postoperative period in participants scheduled for open heart surgery for a year. It was planned to compare the obtained data in terms of participants undergoing valve and coronary bypass surgery, age, gender, diabetes, kidney disease, chronic obstructive pulmonary disease (COPD), surgical characteristics, bypass time, and crossclamping time.

Primary Outcome Measures

Name	Time	Method
Evaluation of postoperative cognitive functions in participants undergoing open heart surgery.	1 year	The aim is to understand whether there is a loss of cognitive functions in the postoperative period, according to the preoperative periods, by testing the participants with open heart surgery on the 3rd day, 7th day, and 2nd month after the surgery.

Secondary Outcome Measures

Name	Time	Method
Comparison with the literature.	1 year	Comparison of the results in the investigators clinic with the literature.
