Đánh giá chức năng lọc của thận trên bệnh nhân phẫu thuật bụng gây mê vòng kín lưu lượng thấp bằng sevofurane

Objective: To evaluate the filtration of renal function during abdominal surgery under low-flow sevoflurane. Subject and method: The study was conducted in 45 patients of abdominal surgery under low-flow sevoflurane at a fresh gas flow level of 1 L/min. Methods for the determination of Glomerular Filtration Rate (GFR): To estimate GFR by Cockroft-Gault's equation from serum creatinine and the method of nuclear medicine by using Tc99m-DTPA (diethylene triamine penta acetic acid). Result: The postanesthetic renal function and Glomerular Filtration Rate studies did not change. Conclusion: Low-flow sevoflurane inhalation anesthesia has no significant effect on the renal function.
