Evaluation of Oxygenation Parameters in Patients Undergoing Rhinoplasty Under General Anesthesia

Overview

The investigators are planning to compare the oxygenation values (Pao2/fio2, lactate etc.) in patients who underwent TCI and inhalation anesthesia in rhinoplasty operation.

Total intravenous anesthesia (TIVA) is a common anesthesia method used today as an alternative to inhalation anesthesia. Loss of consciousness is two important components of general anesthesia, in order to give the patient safe analgesia and not to remember any adverse events related to the operation. While the depth of anesthesia can be controlled by monitoring the minimum alveolar concentration (MAK) in the ventilator devices in the operating room we use modernly, there was no more objective method than measuring the plasma level of drugs in intravenous anesthesia. The schemes created by the anesthetists according to plasma drug levels were used when administering total intravenous anesthesia. Target Controlled Anesthesia (TCI) devices, on the other hand, are pumps that have been used more frequently recently and that can deliver the required blood concentration of a drug in bolus and infusion form according to pharmacokinetics models calculated with personal data. In TCI anesthesia, intravenous infusion of anesthetics provides a more stable drug concentration in the plasma and at the site of action compared to repeated bolus techniques. Thus, it is ensured that the drug remains in the therapeutic range, avoiding the consequences such as over- or under-administration of the drugs. The subject of the study is to determine which of the 2 routinely used methods in rhinoplasty operations affects respiratory functions less.
