Abstract:
Objective To evaluate the effects of inhalation anesthesia with low-flow sevoflurane on the renal function of neonates.Methods Forty ASA physical status Ⅰ or Ⅱ neonates undergoing abdominal surgery under general anesthesia,aged 6-28 days,weighing 1730-2928 g,were included in the study.After induction of anesthesia,anesthesia was maintained with sevoflurane inhalation using a semi-closed circuit system (FGF 1 L/min).The end-tidal concentration of sevoflurane was maintained at 2.5％-4.0％ according to the vital signs.Before induction of anesthesia,immediately after operation,and at 24,48 and 72 h after operation,blood samples from the peripheral vein and urine specimens were taken for determination of serum concentrations of creatinine (Cr),blood urea nitrogen (BUN),urinary retinol binding protein (RBP) and β-N-acetyl-glucosaminidase (NAG).A temperature probe was inserted to the center of soda lime canister.Results Compared with the baseline value at T0,no significant changes were found in the serum Cr and BUN concentrations at T1-4,urinary RBP concentrations were increased at T1,no significant changes were found in urinary RBP concentrations at T2-4,NAG concentrations were significantly increased at T2 and no significant changes were found in NAG concentrations at T1,3,4.The temperature of soda lime was (37 ± 3) ℃ at the end of operation.Conclusion Inhalation anesthesia with low-flow sevoflurane (FGF 1 L/min) produces no significant effect on the renal function of neonates.
