Description of intervention(s) / exposure
It is often not possible to determine the reserve of organ functions in geriatric patients undergoing surgical intervention. Therefore; In this age group, it is very important to apply the ideal amount of fluid and / or blood replacement during intraoperative period in order to prevent possible organ damage. The use of Perioperative Targeted Fluid Therapy Technologies helps the anesthesiologist closely monitor the patient and establish a delicate balance between benefit and risk. Plethysmatic variability index monitoring (PVI-Pleth Variability Index) is a non-invasive, automatic and continuous monitor that shows the fluid response of the patients and is one of the easily applicable and easily interpretable monitoring methods. It has been shown that intraoperative hypotension and fluid requirement can be predicted by PVI monitoring.The aim of this study was to determine the effect of Pleth Variability Index (Pleth) Index monitoring on intraoperative volume replacement in geriatric patients undergoing surgical intervention.

MATERIAL AND METHOD:
After approval of the ethics committee and written consent of the patient; 100 patients over the age of 65 (ASA class 2-3) undergoing elective surgery were included in the study. In addition to standard monitoring, PVI monitoring was performed in all patients. After randomization with closed envelope method, intraoperative fluid and blood product replacement was performed in half of the patients based on PVI data (threshold value 13%) (Group PVI); In the other half, PVI values were blinded and applied by conventional methods (Group K). Hemodynamic values, fluid and blood product amount, vasopressor requirements were recorded at 15-minute intervals and t, Mann-Whitney U or chi-square tests were evaluated. Administers the intervention by anaesthesiologists.
