Comparison of Automated Control Anesthesia & Manual Control Anesthesia in

Status Completed

Clinical Trial Summary

With the introduction of technology into our lives, we come across two different anesthesia management modules in anesthesia machines. The first of these is the traditional method, the manual controlled anesthesia technique; the other is the automatic controlled anesthesia technique. In our daily practice, both anesthesia techniques can be used in patients who have undergone general anesthesia. These two techniques can be used in both high-flow anesthesia and low-flow anesthesia applications.

Clinical Trial Description

In the manual technique, the inspired and exhaled gas concentrations are regulated by the anesthetists manually by the fresh gas flow during general anaesthesia. When administered manually, low-flow anesthesia requires the attention and time of the anesthesiologist, especially the difference between the gas concentrations set in the anesthesia machine and the respiratory system, and the delay between changes in fresh gas concentrations and the end tidal fraction (EtAA) of the anesthetic agent. The most important risks of manually controlled low-flow anesthesia are hypoxia and awareness that may occur due to low doses of inhaler anesthetic agents. In the automatic controlled anesthesia technique, it is a method in which the values desired by the anesthetists during general anesthesia are determined at the beginning of anesthesia and automatically adjusted by the anesthesia device without any additional intervention. After intubation, anesthetists set 3 parameters on the anesthesia device: inspiratory or expiratory oxygen fraction (FiO2- End tidal O2 concentration), anesthetic agent concentration (MAC or End-tidal Anesthetic agent concentration) and fresh gas flow amount. With this method, it is aimed to provide safer and more stable anesthesia. In addition, it has been stated in many previous studies that automatic control anesthesia technique reduces anesthetic gas consumption and less anesthesiologist intervention is needed to reach target values. In our study, we aimed to compare the safety, efficiency and cost aspects of automatic controlled anesthesia and manual control methods in achieving intraoperative target anesthetic and oxygen concentrations. We hypothesized that anesthesia applied with the end-tidal control method would have a lower cost, less workload, and similar anesthetic depth with the manual control method. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
