Brief summary
This study was planned as a single-center, prospective, randomized trial. Adult patients undergoing elective spinal surgery lasting longer than three hours, performed in a neurosurgery operating room, will be evaluated. Patients managed with three different anesthesia methods currently used will be examined for recovery patterns: 1. Total intravenous anesthesia (TIVA), 2. TIVA Combined anesthesia with sevoflurane and intravenous agents (sevoflurane-CIVIA), 3. TIVA Combined anesthesia with desflurane and intravenous agents (desflurane-CIVIA). Recovery patterns include; extubation time, eye opening time, emergence agitation, postoperative nausia and vomiting and postoperative recovery unit discharge time.
Detailed description
The aim of this study was to compare the effects of different anesthesia methods applied in spinal surgeries lasting longer than three hours on postoperative recovery time. Specifically, it aimed to determine the contribution of low-dose (0.5 MAC) desflurane or sevoflurane combined intravenous anesthesia (CIVIA) approaches compared to total intravenous anesthesia (TIVA) on recovery parameters such as patient recovery time, extubation time, and time to consciousness. It also aimed to investigate whether the desflurane-containing combination resulted in a faster recovery than the sevoflurane-containing combination. TIVA will be administered using target-controlled infusion (TCI) with the Eleveld pharmacokinetic efect site model, utilizing a propofol-remifentanil combination, and guided by BIS monitoring. Outputs: Eye opening time (the time from the end of anesthesia until the patient's eye opening for verbal stimuli) Extubation time (the time from the end of anesthesia until extubation) Richardson agitation sedation and RAMSEY scale values, and Emergence agitation incidence. Postoperative nausea and vomiting incidence (PONV). Time to discharge from the PACU and time to an Aldrate score \>9 will be calculated.
Interventions
DRUGSevofluorane
In this group of patients, \<0.5 MAC sevoflurane will be used in combination with TIVA. (TIVA method described above)
DRUGDesflurane
In this group of patients, \<0.5 MAC Desflurane will be used in combination with TIVA.
In this group, TIVA will be applied with the combination of BIS-guided propofol + remifentanil.
