Estimating the share of effect of risk factors on delirium in the elderly endoscopic candidate

Abstract

the administration of benzodiazepines and narcotic drugs or strong sedatives such as ketamine and propofol, which are injected to tolerate endoscopy, all lead to delirium to some extent; If we don't control other factors affecting delirium, the probability of getting this complication will increase many times and the stay in the hospital for these patients who are considered as outpatients will increase many times. Therefore, there is a need to determine the effect of factors affecting delirium in elderly candidates for endoscopy. The results of past studies indicate that delirium is a multifactorial process, and knowing its risk factors and estimating the contribution of each of them can be useful in taking preventive measures. Therefore, according to the mentioned materials, the purpose of the present study is to estimate the contribution of the effect of risk factors on delirium in elderly candidates for endoscopy. Methods: Three hours after endoscopy, Neecham tool was used to check for delirium. This tool is used to check the risk of delirium and examines the psychological state of the person. Information related to underlying diseases, demographic status, and medications were recorded for each patient, and the contribution of each factor to the incidence of delirium was determined. Results: Age over 70 years is 3.14 times, smoking is 1.96 times, living alone is 3.25 times, ASA class above 2 is 5.14 times, diabetes mellitus is 5.25 times, high blood pressure 3.41 times, history of heart attack 5.44 times, stroke 9.37 times, depression 9.77 times, previous delirium 24.86 times 15.37 times polypharmacy, 14.36 times psychiatric medication, 3.27 times propofol injection during endoscopy, 8.27 times midazolam infusion during endoscopy, and 8.27 times fentanyl injection during endoscopy. Size increases the risk of delirium by 3.57 times in elderly candidates for endoscopy.
