Comparison of hemodynamics in general anesthesia patients with total intravenous anesthesia (TIVA) and balanced anesthesia techniques at RSI Purwokerto

Abstract

Background: General anesthesia can cause hemodynamic changes that may increase the risk of perioperative complications. Selecting the appropriate anesthetic technique, such as Total Intravenous Anesthesia (TIVA) and balanced anesthesia, is crucial for maintaining the patient’s stability. This study aims to compare hemodynamic changes in patients undergoing general anesthesia with these two techniques at RSI Purwokerto.

Method: This study employed a non-experimental quantitative design with a descriptive-comparative and longitudinal observational approach. Sampling was conducted using purposive sampling, a non-probability technique. The sample consisted of 46 participants divided into a TIVA group (n=23) and a balanced anesthesia group (n=23). The parameters observed included blood pressure, pulse rate, mean arterial pressure (MAP), respiratory rate, and oxygen saturation at baseline and at 5, 10, and 15 minutes post-induction. Analysis was performed using the Friedman, Wilcoxon, and Mann-Whitney tests.

Results: The results showed significant differences in systolic blood pressure at 15 minutes (p=0.030) and respiratory rate (p=0.007), whereas heart rate and oxygen saturation did not differ significantly (p>0.05). Overall, the TIVA group demonstrated better hemodynamic stability compared to the balanced anesthesia group.

Conclusion: TIVA is more effective in maintaining hemodynamic stability in patients under general anesthesia than balanced anesthesia.
