Stability Comparison of TIVA and Sevoflurane in Prone Spinal Surgery(TIVA:Total Intravenous Anesthesia)

Overview

Key Points: 1. Objective: o To compare the effects of Total Intravenous Anesthesia (TIVA) and sevoflurane anesthesia on respiratory mechanics, hemodynamic parameters, and neuromonitoring during prone position spinal surgeries. 2. Methodology: * A randomized controlled trial involving 52 patients scheduled for lumbar spine surgery, randomly assigned to either TIVA or sevoflurane groups. * Respiratory and hemodynamic parameters were measured at various time points. 3. Results: * No significant differences were found between the TIVA and sevoflurane groups in terms of respiratory mechanics or hemodynamic stability. * Both anesthesia techniques maintained stable intraoperative conditions. 4. Clinical Implications: * Anesthesiologists can flexibly choose between TIVA and sevoflurane based on patient-specific factors and surgical requirements. * TIVA may be preferred in surgeries with high neurological risk due to its compatibility with neuromonitoring. 5. Future Research: * Studies with broader patient populations and long-term outcomes are needed to further refine anesthesia management strategies. * Research on the environmental impact and cost-effectiveness of anesthesia techniques is also important.

This study aims to evaluate the impact of total intravenous anesthesia (TIVA) versus sevoflurane anesthesia on respiratory mechanics and hemodynamic parameters during spinal surgery performed in the prone position. Anesthesia management for spinal surgeries in the prone position is particularly challenging due to significant physiological changes. Identifying the effects of different anesthesia techniques is essential to enhance patient outcomes and ensure intraoperative stability. This randomized controlled trial involved 52 patients scheduled for lumbar spine surgery under general anesthesia. Participants were randomly allocated to either the TIVA group (n=26) or the sevoflurane group (n=26). Measurements of respiratory mechanics, including peak airway pressure (Ppeak), mean airway pressure (Pmean), positive end-expiratory pressure (PEEP), end-tidal CO2 (ETCO2), tidal volume (VT), respiratory rate (RR), and minute ventilation (MV), were taken at various intervals. Hemodynamic parameters such as systolic and diastolic blood pressures and heart rate were continuously monitored.
