ABSTRACT: Background: Because body temperature is such an important indicator and a basic requirement for all kinds of life, even tiny variances might induce undesired changes. This study looked at the influence of FGFs sevoflurane anesthesia on heat preservation in patients undergoing open or laparoscopic digestive surgery. Materials and Methods: Two hundred and forty adult patients (18 - 75 years) with an ASA of I-II were scheduled for open and laparoscopic digestive surgery: open surgery (Group O, n = 120 patients) and laparoscopic surgery (Group L, n = 120 patients). Each group was separated randomly into four subgroups (n = 30 patients) based on FGFs (0.7, 1, 1.5, or 2 L/min). Each patient’s HR, MBP, SpO2, FiO2, fluid infusion amount, urine volume, pre/post-Hb, surgery time, and nasopharyngeal temperatures were investigated and recorded every 15 min from 0 to 120 min. Results: Between groupings, there were no significant changes in demographic features. In 240 patients, the results of various FGFs (0.7, 1, 1.5, and 2 L/min), no statistically significant differences were found in core body temperature over time within each subgroup, with no statistically significant differences between the two (open and laparoscopic) (P > 0.05). Conclusions: The study concluded that FGFs (0.7, 1, 1.5, and 2 L/min) could be utilized safely in adult patients undergoing open or laparoscopic digestive surgery. FGFs (0.7, 1, 1.5, and 2 L/min) provide better body heat preservation during surgical operations.
