This study looked at the influence of FGFs sevoflurane anesthesia on heat preservation in patients undergoing open or laparoscopic digestive surgery. <b>Materials and Methods:</b> 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, SpO<sub>2</sub>, FiO<sub>2</sub>, 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. <b>Results:</b> 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). <b>Conclusions:</b> 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.展开更多

A major challenge was the scarcity of mechanical ventilators, which resulted in the use of anaesthesia devices for this purpose. However, they are quite different from mechanical ventilators used in Intensive Care Units and some adaptations, such as the use of high flow to reduce CO2 rebreathing, were necessary to ensure patient safety. The objective of this study was to present a mathematical formula and develop a tool that can be used to adjust the flow of oxygen and air in flow metres of anaesthesia devices that do not have oxygen analysers or these analysers are not operational. A literature review was conducted using the main health databases and libraries as research sources: PubMed, Virtual Health Library (VHL), SciELO, and Cochrane. The review included studies published in English, Spanish, and Portuguese. Animal studies were excluded. A total of 11 references were included to support this article.展开更多
