Summary

Drugs with anticholinergic properties are widely prescribed in the elderly population, despite increasing evidence in the literature regarding side effects and adverse outcomes. As is known, many drugs have anticholinergic activity, which means that they block the binding of the neurotransmitter acetylcholine to the muscarinic receptor. In this case, the occurrence of anticholinergic side effects becomes inevitable. Central effects such as cognitive impairment, dizziness, sedation, confusion or delirium, and peripheral effects such as dry mouth, dry eyes, constipation, urinary retention, and tachycardia begin to be seen in patients. Anticholinergic load refers to the cumulative effect of taking one or more drugs with anticholinergic activity. This cumulative effect is a strong indicator of cognitive and physical deterioration, especially in the elderly population. It is also associated with adverse outcomes such as falls, impaired functioning, and higher rates of hospitalization and death. Anticholinergic load scales include scales that facilitate the work of physicians used in clinical practice to predict anticholinergic side effects in humans. Although there are many different scales used at this point, one of the scales with the highest validity and reliability in recent studies are Anticholinergic cognitive burden scale (ACB) and Anticholinergic risk scale (ARS). To the best of our knowledge, we could not find any study on postoperative complications, length of hospital stay and mortality after cardiac surgery with these scales. Therefore, we aimed to examine the relationship between possible complications after cardiac surgery and anticholinergic load scales showing the cumulative effect of preoperative drugs.
