Oxidative Stress Effects of TIVA, CIVA, and Balanced Anesthesia in VATS
Sponsor: Ataturk University
Summary
The primary objective of our study is to compare the effects of total intravenous anesthesia (TIVA), combined intravenous-volatile anesthesia (CIVA), and balanced anesthesia (BAL) methods on perioperative oxidative stress parameters, such as Malondialdehyde (MDA), Total Oxidant Status (TOS), Total Antioxidant Status (TAS), and Superoxide Dismutase (SOD), in patients undergoing video-assisted thoracoscopic surgery (VATS). The secondary objective is to record perioperative vital parameters, arterial blood gas values obtained at specific stages of the surgery, and the incidence of postoperative nausea and vomiting (PONV).

Conditions
Interventions
Total Intravenous Anesthesia (TIVA) Group
Anesthesia induction will include 2 mg midazolam, 2-2.5 mg/kg propofol, 0.6-0.9 mg/kg rocuronium, and 1 μg/kg remifentanil. Maintenance will be provided with target-controlled infusion (TCI) propofol at a Ce of 4-6 μg/mL and TCI remifentanil at a Ce of 1.5-3 ng/mL while maintaining the bispectral index (BIS) between 40-60.
Balanced Anesthesia (BAL) Group
Induction will follow the same protocol as the TIVA group. During maintenance, desflurane 5-7% (MAC 1-1.3) and TCI remifentanil at a Ce of 1.5-3 ng/mL will be administered, targeting a BIS value between 40-60.
Combined Intravenous Volatile Anesthesia
Induction will follow the same protocol as other groups. Maintenance will include TCI propofol at a Ce of 2-4 μg/mL and TCI remifentanil at a Ce of 1.5-3 ng/mL along with 3% desflurane (MAC 0.5), keeping BIS values between 40-60.
